Ovary
The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
Polycystic Ovary Syndrome
A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.
Cricetinae
A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.
CHO Cells
CELL LINE derived from the ovary of the Chinese hamster, Cricetulus griseus (CRICETULUS). The species is a favorite for cytogenetic studies because of its small chromosome number. The cell line has provided model systems for the study of genetic alterations in cultured mammalian cells.
Ovarian Follicle
An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.
Cricetulus
A genus of the family Muridae consisting of eleven species. C. migratorius, the grey or Armenian hamster, and C. griseus, the Chinese hamster, are the two species used in biomedical research.
Ovulation
The discharge of an OVUM from a rupturing follicle in the OVARY.
Granulosa Cells
Supporting cells for the developing female gamete in the OVARY. They are derived from the coelomic epithelial cells of the gonadal ridge. Granulosa cells form a single layer around the OOCYTE in the primordial ovarian follicle and advance to form a multilayered cumulus oophorus surrounding the OVUM in the Graafian follicle. The major functions of granulosa cells include the production of steroids and LH receptors (RECEPTORS, LH).
Hyperandrogenism
A condition caused by the excessive secretion of ANDROGENS from the ADRENAL CORTEX; the OVARIES; or the TESTES. The clinical significance in males is negligible. In women, the common manifestations are HIRSUTISM and VIRILISM as seen in patients with POLYCYSTIC OVARY SYNDROME and ADRENOCORTICAL HYPERFUNCTION.
Ovarian Diseases
Pathological processes of the OVARY.
Follicular Atresia
The degeneration and resorption of an OVARIAN FOLLICLE before it reaches maturity and ruptures.
Oogenesis
The process of germ cell development in the female from the primordial germ cells through OOGONIA to the mature haploid ova (OVUM).
Theca Cells
The flattened stroma cells forming a sheath or theca outside the basal lamina lining the mature OVARIAN FOLLICLE. Thecal interstitial or stromal cells are steroidogenic, and produce primarily ANDROGENS which serve as precusors of ESTROGENS in the GRANULOSA CELLS.
Progesterone
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
Follicle Stimulating Hormone
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.
Ovarian Neoplasms
Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.
Oocytes
Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM).
Gonadotropins, Equine
Gonadotropins secreted by the pituitary or the placenta in horses. This term generally refers to the gonadotropins found in the pregnant mare serum, a rich source of equine CHORIONIC GONADOTROPIN; LUTEINIZING HORMONE; and FOLLICLE STIMULATING HORMONE. Unlike that in humans, the equine LUTEINIZING HORMONE, BETA SUBUNIT is identical to the equine choronic gonadotropin, beta. Equine gonadotropins prepared from pregnant mare serum are used in reproductive studies.
Corpus Luteum
The yellow body derived from the ruptured OVARIAN FOLLICLE after OVULATION. The process of corpus luteum formation, LUTEINIZATION, is regulated by LUTEINIZING HORMONE.
Ovarian Cysts
General term for CYSTS and cystic diseases of the OVARY.
Chorionic Gonadotropin
A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).
Luteinizing Hormone
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.
Estradiol
The 17-beta-isomer of estradiol, an aromatized C18 steroid with hydroxyl group at 3-beta- and 17-beta-position. Estradiol-17-beta is the most potent form of mammalian estrogenic steroids.
Gonadotropins
Hormones that stimulate gonadal functions such as GAMETOGENESIS and sex steroid hormone production in the OVARY and the TESTIS. Major gonadotropins are glycoproteins produced primarily by the adenohypophysis (GONADOTROPINS, PITUITARY) and the placenta (CHORIONIC GONADOTROPIN). In some species, pituitary PROLACTIN and PLACENTAL LACTOGEN exert some luteotropic activities.

Anovulation
Suspension or cessation of OVULATION in animals or humans with follicle-containing ovaries (OVARIAN FOLLICLE). Depending on the etiology, OVULATION may be induced with appropriate therapy.
Estrous Cycle

Estrus
The period in the ESTROUS CYCLE associated with maximum sexual receptivity and fertility in non-primate female mammals.
Oligomenorrhea
Abnormally infrequent menstruation.
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Androstenedione
A delta-4 C19 steroid that is produced not only in the TESTIS, but also in the OVARY and the ADRENAL CORTEX. Depending on the tissue type, androstenedione can serve as a precursor to TESTOSTERONE as well as ESTRONE and ESTRADIOL.
Granulosa Cell Tumor
A neoplasm composed entirely of GRANULOSA CELLS, occurring mostly in the OVARY. In the adult form, it may contain some THECA CELLS. This tumor often produces ESTRADIOL and INHIBIN. The excess estrogen exposure can lead to other malignancies in women and PRECOCIOUS PUBERTY in girls. In rare cases, granulosa cell tumors have been identified in the TESTES.
Sexual Maturation
Achievement of full sexual capacity in animals and in humans.
Testis
The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS.
Infertility, Female
Diminished or absent ability of a female to achieve conception.
Testosterone
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
Uterus
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
Amino Acid Sequence
The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.
Follicular Phase
The period of the MENSTRUAL CYCLE representing follicular growth, increase in ovarian estrogen (ESTROGENS) production, and epithelial proliferation of the ENDOMETRIUM. Follicular phase begins with the onset of MENSTRUATION and ends with OVULATION.
Anti-Mullerian Hormone
A glycoprotein that causes regression of MULLERIAN DUCTS. It is produced by SERTOLI CELLS of the TESTES. In the absence of this hormone, the Mullerian ducts develop into structures of the female reproductive tract. In males, defects of this hormone result in persistent Mullerian duct, a form of MALE PSEUDOHERMAPHRODITISM.
Transfection
The uptake of naked or purified DNA by CELLS, usually meaning the process as it occurs in eukaryotic cells. It is analogous to bacterial transformation (TRANSFORMATION, BACTERIAL) and both are routinely employed in GENE TRANSFER TECHNIQUES.
Follicular Fluid
The fluid surrounding the OVUM and GRANULOSA CELLS in the Graafian follicle (OVARIAN FOLLICLE). The follicular fluid contains sex steroids, glycoprotein hormones, plasma proteins, mucopolysaccharides, and enzymes.
Base Sequence
The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.

Aromatase
An enzyme that catalyzes the desaturation (aromatization) of the ring A of C19 androgens and converts them to C18 estrogens. In this process, the 19-methyl is removed. This enzyme is membrane-bound, located in the endoplasmic reticulum of estrogen-producing cells of ovaries, placenta, testes, adipose, and brain tissues. Aromatase is encoded by the CYP19 gene, and functions in complex with NADPH-FERRIHEMOPROTEIN REDUCTASE in the cytochrome P-450 system.
Ovariectomy
The surgical removal of one or both ovaries.
Androgens
Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.
Recombinant Proteins
Proteins prepared by recombinant DNA technology.
Inhibins
Glycoproteins that inhibit pituitary FOLLICLE STIMULATING HORMONE secretion. Inhibins are secreted by the Sertoli cells of the testes, the granulosa cells of the ovarian follicles, the placenta, and other tissues. Inhibins and ACTIVINS are modulators of FOLLICLE STIMULATING HORMONE secretions; both groups belong to the TGF-beta superfamily, as the TRANSFORMING GROWTH FACTOR BETA. Inhibins consist of a disulfide-linked heterodimer with a unique alpha linked to either a beta A or a beta B subunit to form inhibin A or inhibin B, respectively
Mutation
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
Vitellogenesis
The active production and accumulation of VITELLINS (egg yolk proteins) in the non-mammalian OOCYTES from circulating precursors, VITELLOGENINS. Vitellogenesis usually begins after the first MEIOSIS and is regulated by estrogenic hormones.
Primary Ovarian Insufficiency
Cessation of ovarian function after MENARCHE but before the age of 40, without or with OVARIAN FOLLICLE depletion. It is characterized by the presence of OLIGOMENORRHEA or AMENORRHEA, elevated GONADOTROPINS, and low ESTRADIOL levels. It is a state of female HYPERGONADOTROPIC HYPOGONADISM.

Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed)
Drug Resistance
Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.

Effect of sex difference on the in vitro and in vivo metabolism of aflatoxin B1 by the rat. (1/8699)

Hepatic microsome-catalyzed metabolism of aflatoxin B1 (AFB1) to aflatoxin M1 and aflatoxin Q1 and the "metabolic activation" of AFB1 to DNA-alylating metabolite(s) were studied in normal male and female Sprague-Dawley rats, in gonadectomized animals, and in castrated males and normal females treated with testosterone. Microsomes from male animals formed 2 to 5 times more aflatoxin M1, aflatoxin Q1, and DNA-alkylating metabolite(s) than those from females. Castration reduced the metabolism of AFB1 by the microsomes from males by about 50%, whereas ovariectomy had no significant effect on AFB1 metabolism by the microsomes from females. Testosterone treatment (4 mg/rat, 3 times/week for about 6 weeks) of castrated immature males and immature females enhanced the metabolism of AFB1 by their microsomes. A sex difference in the metabolism of AFB1 by liver microsomes was also seen in other strains of rats tested: Wistar, Long-Evans, and Fischer. The activity of kidney microsomes for metabolic activation was 1 to 4% that of the liver activity and was generally lower in microsomes from male rats as compared to those from female rats of Sprague-Dawley, Wistar, and Long-Evans strains. The in vitro results obtained with hepatic microsomes correlated well with the in vivo metabolism of AFB1, in that more AFB1 became bound in vivo to hepatic DNA isolated from male rats and from a female rat treated with testosterone than that isolated from control female rats. These data suggest that the differences in hepatic AFB1 metabolism may be the underlying cause of the sex difference in toxicity and carcinogenicity of AFB1 observed in rats.  (+info)

Apontic binds the translational repressor Bruno and is implicated in regulation of oskar mRNA translation. (2/8699)

The product of the oskar gene directs posterior patterning in the Drosophila oocyte, where it must be deployed specifically at the posterior pole. Proper expression relies on the coordinated localization and translational control of the oskar mRNA. Translational repression prior to localization of the transcript is mediated, in part, by the Bruno protein, which binds to discrete sites in the 3' untranslated region of the oskar mRNA. To begin to understand how Bruno acts in translational repression, we performed a yeast two-hybrid screen to identify Bruno-interacting proteins. One interactor, described here, is the product of the apontic gene. Coimmunoprecipitation experiments lend biochemical support to the idea that Bruno and Apontic proteins physically interact in Drosophila. Genetic experiments using mutants defective in apontic and bruno reveal a functional interaction between these genes. Given this interaction, Apontic is likely to act together with Bruno in translational repression of oskar mRNA. Interestingly, Apontic, like Bruno, is an RNA-binding protein and specifically binds certain regions of the oskar mRNA 3' untranslated region.  (+info)

Utero-ovarian interaction in the regulation of reproductive function. (3/8699)

The physiological regulation of fertile reproductive cycle in mammals depends on interactions between hypothalamus-pituitary, ovarian and uterine stimuli. Over the past 20 years, much has been learned about the interrelation between the affluent and effluent lymph and vascular drainage in and around both ovarian and uterine tissues. An essential feature in the regulation of the fertile cycle is the functional status of the ovary, particularly the corpus luteum. During the time of implantation and the early pregnancy, an active corpus luteum is essential. As human chorionic gonadotrophin (HCG) is important in the maintenance of the corpus luteum, we investigated if it was produced by the cyclic endometrium. Immunohistochemical and in-situ hybridization reactions were performed but neither identified the presence of HCG during the proliferative phase. Positive staining and beta-human chorionic gonadotrophin (beta-HCG) mRNA were observed during the secretory phase in the glandular cells of the endometrium. The results were confirmed by Western blotting of secretory phase endometrium extracts and assessment of the functional secretory capacity of primary endometrial cultures. Polymerase chain reaction (PCR) investigations showed a positive result in the secretory phase. We postulate that, based on the very close morphological interrelation between the uterus and the ovary, the beta-HCG of the endometrium is the primary factor for the maintenance of the corpus luteum and early pregnancy.  (+info)

Uterine peristalsis during the follicular phase of the menstrual cycle: effects of oestrogen, antioestrogen and oxytocin. (4/8699)

Uterine peristalsis, directing sustained and rapid sperm transport from the external cervical os or the cervical crypts to the isthmic part of the tube ipsilateral to the dominant follicle, changes in direction and frequency during the menstrual cycle, with lowest activity during menstruation and highest activity at mid cycle. It was therefore suggested that uterine peristalsis is under the control of the dominant follicle with the additional involvement of oxytocin. To test this hypothesis, vaginal sonography of uterine peristalsis was performed in the early, mid and late proliferative phases, respectively, of cycles of women treated with oestradiol valerate and with human menopausal gonadotrophin following pituitary downregulation, with clomiphene citrate and with intravenous oxytocin, respectively. Administration of oestradiol valerate resulted in oestradiol serum concentrations comparable with the normal cycle with a simulation of the normal frequency of peristaltic contractions. Elevated oestradiol concentrations and bolus injections of oxytocin resulted in a significant increase in the frequency of peristaltic contractions in the early and mid follicular phases, respectively. Chlomiphene tended, though insignificantly so, to suppress the frequency of peristaltic waves in the presence of elevated oestradiol concentrations. In the late follicular phase of the cycle extremely elevated oestradiol concentrations as well as the injection of oxytocin resulted only in an insignificant further increase of peristaltic frequency. In the normal cycles, as well as during extremely elevated oestradiol concentrations and following oxytocin administration, the peristaltic contractions were always confined to the subendometrial layer of the muscular wall. The results and the review of literature indicate that uterine peristalsis during the follicular phase of the menstrual cycle is controlled by oestradiol released from the dominant follicle with the probable involvement of oxytocin, which is presumably stimulated together with its receptor within the endometrial-subendometrial unit and therefore acting in an autocrine/paracrine fashion. Since unphysiological stimulation with oestradiol and oxytocin did not significantly increase the frequency of uterine peristalsis in the late follicular phase of the cycle it is assumed that normal preovulatory frequency of uterine peristalsis is at a level which cannot be significantly surpassed due to phenomena of refractoriness of the system.  (+info)

Sonographic evidence for the involvement of the utero-ovarian counter-current system in the ovarian control of directed uterine sperm transport. (5/8699)

Sperm transport from the cervix into the tube is an important uterine function within the process of reproduction. This function is exerted by uterine peristalsis and is controlled by the dominant ovarian structure via a cascade of endocrine events. The uterine peristaltic activity involves only the stratum subvasculare of the myometrium, which exhibits a predominantly circular arrangement of muscular fibres that separate at the fundal level into the fibres of the cornua and continue into the circular muscles of the respective tubes. Since spermatozoa are transported preferentially into the tube ipsilateral to the dominant follicle, this asymmetric uterine function may be controlled by the ovary via direct effects utilizing the utero-ovarian counter-current system, in addition to the systemic circulation. To test this possibility the sonographic characteristics of the uterine vascular bed were studied during different phases of the menstrual cycle. Vaginal sonography with the measurement of Doppler flow characteristics of both uterine arteries and of the arterial anastomoses of the uterine and ovarian arteries (junctional vessels) in the cornual region of both sides of the uterus during the menstrual phase of regular-cycling women demonstrated significant lower resistance indices of the junctional vessels ipsilateral to the side of the dominant ovarian structure as compared with the corresponding arteries contralaterally. By the use of the perfusion mode technique, it could be observed that vascular perfusion of the fundal myometrium was significantly increased ipsilateral to the dominant follicle during the late follicular phase of the cycle. These results show that the endocrine control of the dominant ovarian structure over uterine function is not only exerted via the systemic circulation but also directly, most probably utilizing the utero-ovarian counter-current system.  (+info)

Endometriotic disease: the role of peritoneal fluid. (6/8699)

Peritoneal fluid and the intraovarian milieu are a specific microenvironment. Peritoneal fluid originates mainly as an ovarian exudation product caused by increased vascular permeability, with cyclic variation in volume and steroid hormones which are always higher than in plasma. It contains large amounts of macrophages and their secretion products, and has a large exchange area with plasma through the peritoneum, which is highly permeable for small molecules. Diffusion becomes virtually zero for molecules with a molecular weight of >100000 Da. In women with the luteinized unruptured follicle (LUF) syndrome, concentrations of oestrogens and progesterone are much lower in the luteal phase. Endometriosis is associated with sterile low-grade inflammation, increased concentrations of activated macrophages and many of their secretions, such as cytokines, growth factors and angiogenic factors. Concentrations of CA-125 and of glycodelins are also increased, secreted locally by the endometrial cells. Natural killer (NK) cell function declines, possibly mediated by glycodelins or local intercellular adhesion molecule (ICAM) -1 shedding. The ovary is also a specific microenvironment, with steroid hormone concentrations 1000-fold higher in follicles than in plasma. Endometrial and superficially implanted cells are influenced by peritoneal fluid concentrations so that local environment, rather than inherent cellular differences could explain differences between superficial endometriosis and eutopic endometrium. Differences between superficial implants and endometriotic disease, deep infiltrating or cystic ovarian endometriosis, may thus arise via different endocrine environments. Superficial endometrial implants are regulated by peritoneal fluid factors, whereas deep endometriosis and cystic ovarian endometriosis are influenced by blood or ovarian factors. The endometriotic disease theory considers superficial endometriotic implants and their remodelling as a physiological process in most women, and concentrates on the causes of severe endometriosis such as differences in the eutopic endometrium from women with and without endometriosis (which may indicate hereditary differences), the invasiveness of some endometriotic cells in vitro, focal 'shielding' of endometriotic foci by adhesions, and inhibition of NK activity by ICAM-1 and glycodelins. Endometriotic disease is thus seen as a benign tumour. The type of cellular lesion, hereditary and immunological environments and local hormone concentrations in the ovary and in peritoneal fluid, will decide expression as cystic ovarian endometriosis, deep endometriosis or adenomyosis externa, and whether the latter is associated with adhesions.  (+info)

Leptin and reproduction. (7/8699)

In the few years since leptin was identified as a satiety factor in rodents, it has been implicated in the regulation of various physiological processes. Leptin has been shown to promote sexual maturation in rodent species and a role in reproduction has been investigated at various sites within the hypothalamo-pituitary-gonadal axis. This review considers the evidence that leptin (or alteration in amount of body fat) can affect reproduction. There is evidence that leptin plays a permissive role in the onset of puberty, probably through action on the hypothalamus, where leptin receptors are found in cells that express appetite-regulating peptides. There is little evidence that leptin has a positive effect on the pituitary gonadotrophs and the gonads. There is also very little indication that leptin acts in an acute manner to regulate reproduction in the short term. It seems more likely that leptin is a 'barometer' of body condition that sends signals to the brain. Studies in vitro have shown negative effects on ovarian steroid production and there are no reports of effects on testicular function. Leptin concentrations in plasma increase in women during pregnancy, owing to production by the placenta but the functional significance of this is unknown. A number of factors that affect the production and action of leptin have yet to be studied in detail.  (+info)

Effect of shellfish calcium on the apparent absorption of calcium and bone metabolism in ovariectomized rats. (8/8699)

Fossil shellfish powder (FS) and Ezo giant scallop shell powder (EG) were rendered soluble with lactate and citrate under decompression (FSEx and EGEx, respectively) and we examined the effects of lactate-citrate solubilization of FS and EG on mineral absorption, tissue mineral contents, serum biochemical indices and bone mineral density (BMD) in ovariectomized (OVX) rats. The apparent absorption ratios of minerals tended to be high in the rats fed with the solubilized mineral sources, those in the FSEx group being significantly higher than in the FS group. There was no significant difference in the tibia mineral content among the OVX groups. BMD at the distal femoral diaphysis was significantly increased by FSEx and EGEx feeding. It is suggested that solubilization with lactate and citrate under decompression increased the solubility and bioavailability of calcium from such natural sources of shellfish calcium as FS and EG.  (+info)

The adult ovarian surface epithelium has already been proposed as a source of stem cells and germinal cells in the literature, it has been termed the germinal epithelium therefore. that neonatal and adult mouse ovaries have come cells which can become effectively proliferated and verified [1C3]. Pacchiarotti et al. [2] discovered in neonatal and adult mouse ovaries two unique populations of feminine germline come cells with different diameters: cells with diameters of 10C15?transgene. These results lead to the fundamental study of ovarian come cells, oogenesis, and a fresh understanding of the physiology of the mammalian ovary and demonstrated that ovarian surface area epithelium might become an essential resource of germinal come cells in adult mouse ovaries. In addition to the mouse model, many related research in human beings also display that adult human being ovarian surface area epithelium might become a resource of Galeterone control cells. Bukovsky et al. verified that oocyte-like cells ...

The adult ovarian surface epithelium has already been proposed as a source of stem cells and germinal cells in the literature, it has been termed the germinal epithelium therefore. that neonatal and adult mouse ovaries have come cells which can become effectively proliferated and verified [1C3]. Pacchiarotti et al. [2] discovered in neonatal and adult mouse ovaries two unique populations of feminine germline come cells with different diameters: cells with diameters of 10C15?transgene. These results lead to the fundamental study of ovarian come cells, oogenesis, and a fresh understanding of the physiology of the mammalian ovary and demonstrated that ovarian surface area epithelium might become an essential resource of germinal come cells in adult mouse ovaries. In addition to the mouse model, many related research in human beings also display that adult human being ovarian surface area epithelium might become a resource of Galeterone control cells. Bukovsky et al. verified that oocyte-like cells ...

Answer (1 of 1): The ovaries are part of the female reproductive system, and are found in pairs among vertebrates (animals with spines). If youre a girl, youll have ovaries in your lower stomach area, where your pelvis is.Where Are The Ovaries, And What Do They Do? In human females, the ovaries are located in the pelvic area, either side of the uterus. Each one is about the size of an almond, and they release a single egg every month, unless youre pregnant.If you have sex, your partners sperm can fertilize this egg, which then turns into a baby. If the egg isnt used, you flush it out during your period, and your ovaries will release another one the following month.How Can I Feel Where My Ovaries Are? The ovaries can be found about four inches below the navel. Each one is out three inches to the side, so that should be just above and inside your hipbones if youre of average height!Youll need to know where your ovaries are if you want to perform a fertility massage. This is supposed to increase

This study demonstrates that different PKC isoforms are differentially expressed in particular cellular components of ovarian follicles of pre-pubertal, pubertal and adult mouse ovaries.. Data obtained from H-Score evaluation of immunohistochemistry findings revealed that PKCα expression was more apparent in oocytes of all follicles in pre-pubertal, pubertal and adult ovaries, though it was also expressed in granulosa cells. Interestingly, in adult and pre-pubertal ovaries, intense immunostaining of PKCα in oocytes was statistically significant in primordial (PND60, PND7 and PND1), primary (PND60, PND7 and PND1) and secondary follicles (PND60 and PND7), whereas in PND21 ovaries only oocytes of primordial follicles had significantly higher immunostaining level of PKCα. These findings support the idea that PKCα expression in oocytes of larger follicles may have low significance due to granulosa-oocyte interactions during initiation of hormone dependent follicular growth [27],[28]. PKCα ...

Diminished ovarian reserve is associated with a poor ovarian response (POR) to gonadotropin stimulation and IVF outcomes. Whether pretreatment with DHEA improves the ovarian response in DOR patients remains debated. In the present study, no statistically significant improvement in ovarian reserve markers, ovarian response, or IVF outcomes was found. However, subgroup analysis showed that the expression of AR and FSHR mRNA in GCs were significantly increased in women with ≥5 oocytes retrieved after DHEA pretreatment, suggesting that DHEA may improve the ovarian response in DOR women through promoting the expression of AR and FSHR in GCs.. Although many studies have focused on the effects of androgens and AR on follicular development, the conclusions are controversial. A recent meta-analysis indicated the clinical pregnancy rate was statistically increased in DOR patients who were pre-treated with DHEA, there was no significant improvement on the number of oocytes retrieved and the cancellation ...

The Drosophila ovary consists of repeated units, the ovarioles, where oogenesis takes place. The repetitive structure of the ovary develops de novo from a mesenchymal cell mass, a process that is initiated by the formation of a two-dimensional array of cell stacks, called terminal filaments, during the third larval instar. We have studied the morphogenetic process leading to the formation of terminal filaments and find that this involves recruitment, intercalation and sorting of terminal filament cells. Two other types of cell stacks that participate in ovary morphogenesis, the basal stalks and interfollicular stalks, also form by cell rearrangement utilizing a convergence and extension mechanism. Terminal filament formation depends on the Bric a brac protein, which is expressed in the nuclei of terminal filament cells and is cell autonomously required. Disruption of terminal filament formation, together with defects of basal and interfollicular stalk development, leads to disruption of ovariole ...

Light microscopy of the fetal primate ovary about 20 weeks of gestation. The ovary is densely populated with oocytes (female germ cells) enclosed with a layer of follicle cells which together are known as follicles. The earliest follicles are called primordial follicles. In most species the fetal ovary is massively oversupplied with oocytes/follicles; in humans there may be up to 5 million per ovary. For reasons that remain unknown the majority (approximately 85%) of follicles die with a few hundred thousand surviving in each ovary at birth.

Ovarian volume correlates strongly with the number of non-growing follicles in the human ovaryOvarian volume correlates strongly with the number of non-growing follicles in the human ovary
A reliable indirect measure of ovarian reserve for the individual woman remains a challenge for reproductive specialists. Using descriptive statistics from a large-scale study of ovarian volumes, we have developed a normative model for healthy females for ages 25 through 85. For average values, this model has a strong and positive correlation (r=0.89) with our recent model of nongrowing follicles (NGFs) in the human ovary for ages 25 through 51. When both models are log-adjusted, the correlation increases to r=0.99, over the full range of ovarian volume. Furthermore we can deduce that an ovary of 3 cm3 volume (or less) contains approximately 1000 NGF (or fewer). These strong correlations indicate that ovarian volume is a useful factor in the indirect estimation of human ovarian reserve for the individual woman ...

Regulation of fibrillins and modulators of TGFβ in fetal bovine and human ovariesRegulation of fibrillins and modulators of TGFβ in fetal bovine and human ovaries
View more ,Fibrillins 1-3 are stromal extracellular matrix proteins that play important roles in regulating TGFβ activity, which stimulates fibroblasts to proliferate and synthesize collagen. In the developing ovary, the action of stroma is initially necessary for the formation of ovigerous cords and subsequently for the formation of follicles and the surface epithelium of the ovary. FBN3 is highly expressed only in early ovarian development and then it declines. In contrast, FBN1 and 2 are upregulated in later ovarian development. We examined the expression of FBN1-3 in bovine and human fetal ovaries. We used cell dispersion and monolayer culture, cell passaging and tissue culture. Cells were treated with growth factors, hormones or inhibitors to assess the regulation of expression of FBN1-3. When bovine fetal ovarian tissue was cultured, FBN3 expression declined significantly. Treatment with TGFβ-1 increased FBN1 and FBN2 expression in bovine fibroblasts, but did not affect FBN3 expression. ...

Although ovarian cancer is rare, it is the most deadly of gynaecological cancers. Unfortunately, still very little is known about the cells that give rise to 90% of ovarian cancers, the ovarian surface epithelial (OSE) cells, and much of the available data remains controversial. This project was designed to address the possible involvement of ovarian stromal/thecal cells in the regulation of OSE cell growth and Kit and KL expression. Such interactions are probably involved in normal OSE-stromal/thecal cell activities as well as in interactions occurring within inclusion cysts and leading to ovarian tumour formation. The regulation of rat OSE (ROSE) cell growth by theca-derived factors and gonadotropins was investigated by proliferation experiments and cell counts. The modulation of Kit and Kit ligand (KL) messenger ribonucleic acid (mRNA) expression in these cells by the same factors was investigated by Northern blot analysis and reverse transcription-polymerase chain reaction (RT-PCR). ...

Role of Progesterone Receptors in Neonatal Ovary Development by Marta N. DzyadykRole of Progesterone Receptors in Neonatal Ovary Development by Marta N. Dzyadyk
In female mammals, proper oocyte development is a vital prerequisite for future gamete viability and fertility. This development of oocytes, known as oogenesis, begins with the migration of primordial germ cells to the genital ridge of the early embryo, where multiple rounds of mitotic division occur without complete cytokinesis. The result is temporary cyst morphology. Cyst breakdown is a crucial process in the next developmental stage, resulting in formation of the single oocytes which will grow in follicles surrounded by granulosa cells and eventually develop into eggs. These aspects of embryogenesis are conserved across multiple species, including Drosophila, mice, and humans. Extensive research has already been completed to elucidate the mechanisms through which the steroid hormone estrogen regulates these developmental processes. Some research shows that progesterone, among other steroid hormones, also plays a role in inhibiting cyst breakdown and disrupting proper follicular assembly. However,

Ovary (plant) : Wikis (The Full Wiki)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the carpel which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. In this picture of a zucchini the petals and sepals are above the ovary and such a flower is said to have an inferior ovary; also referred to as epigynous. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to grow into one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. The carpel together with all the female components including ovules, placental tissue, style and stigma are called gynoecium. The carpel is considered to be a modified leaf. A pea shell is a good example of a carpel and shows the genetic and morphological relationship to a leaf.. ...

According to Dr. Peter Kenemans at OBGYYN.net, Early removal of one ovary or a substantial part of a functional ovary (e.g., by a large wedge resection) can provoke menopause by reducing the actual amount of follicles still present. You still still experience the same symptoms, but there is no other dramatic change. ...

The prolonged, gonadotoxic effect of chemotherapy can finally lead to infertility in female cancer survivors. There is controversial evidence regarding the protective role of gonadotropin-releasing hormone analogue (GnRH-a) on chemotherapy-induced ovarian damage. In the present study on a murine model, ultrasound (US) and contrast-enhanced US (CEUS) were firstly used to characterise ovarian glands in normal conditions to validate a preclinical model. In addition, preliminary findings were obtained on anatomical and vascular ovarian changes induced by GnRH-a based on decapeptyl administration. Ovaries were accurately assessed with US and CEUS in a murine model placed in prone position, providing quantitative and reproducible information. Ovaries were identified in 40/40 cases and CEUS analysis was successfully performed in 20/20 cases with 100% technical success.

The primary causes of POR remain elusive and oxidative stress was proposed as one of the important contributors. It has been suggested that focus on the specific subpopulations within heterogeneous group of poor responders could assist in evaluating optimal management strategies for these patients. This study investigated the effect of anti-oxidant treatment with coenzyme Q10 (CoQ10) on ovarian response and embryo quality in young low-prognosis patients with POR.

High-fat diet (HFD) consumption in female rodents causes impaired estrous cyclicity, fewer pups per litter, and dysregulation of key ovulatory genes suggesting that HFD-induced subfertility may be due to ovulatory dysfunction. To test this hypothesis female mice were fed chow or HFD for 10 weeks at which point ovulation and ovarian gene expression of endothelin-2 (Edn2), a gene critical for ovulation, were assessed. After 10 weeks of HFD, both mice that remained lean and those that became obese had fewer ovulated oocytes than chow controls (P = 0.041, P = 0.0030, respectively). In chow controls, Edn2 was expressed as expected with basal levels during diestrus and proestrus, increased 11.6-fold during estrus, and decreased to basal levels during metestrus. In HFD mice, Edn2 was dysregulated across the entire estrous cycle as were other Edn2 system components (endothelin converting enzyme 1 (Ece-1), and the endothelin receptors (Ednra, Ednrb)). Interestingly, we found dysregulation of key ovarian ...

The expression of HeLa cell miR-15 to miR-33 was examined by Northern blotting using HeLa cell total RNA, in addition to total RNA prepared from mouse kidney, adult zebrafish, Xenopus laevis ovary, and D. melanogaster S2 cells (Fig. 1B andTable 2). miR-15 and miR-16 are encoded in a gene cluster (Fig. 2B) and are detected in mouse kidney, adult zebrafish, and very weakly in frog ovary, which may result from miRNA expression in somatic ovary tissue rather than in oocytes. mir-17 to mir-20 are also clustered (Fig. 2B) and are expressed in HeLa cells and adult zebrafish, but undetectable in mouse kidney and frog ovary (Fig. 1 andTable 2), and therefore represent a likely case of tissue-specific miRNA expression..

In this review we analyze the involvement of cytokines in regulation of ovarian function. A growing body of evidence suggests that the ovary is a site of inflammatory reactions. Immune-competent cells present within the ovary may constitute potential in-situ modulators of ovarian function that act through local secretion of regulatory soluble factors - cytokines. In addition many over cell in the ovary also pro- duce cytokines independently of the presence of leukocytes, thus ovaries are sites of cytokine action and production. There are many evidences that cytokines are involved in the ovarian control of follicular development and are surveyed as the important regulators of steroidogenesis and gamete produc- tion. It is established that cytokines generally inhibit gonadot- ropin-stimulated production of steroids. However ovarian ste- roids, in turn, reduce the cytokine production by immune- competent cells. There are some data about participation of cytokines in regulating the proliferation and ...

Ovaries - Female Anatomy: Internal Parts
Incredibly, each young female infant is born with all of her potential eggs. In fact, most girls are born with an estimated 1,000,000 eggs. A womans eggs cannot be created, copied, or grown; moreover, eggs are simply an inherent part of even a nearly fully developed fetus female anatomy. The Ovaries, which store these eggs, must mature one egg each month (for women with a regular menstrual / reproductive cycle), as the Ovaries must also send the matured egg off to the Fallopian Tubes. As there is both a right and left Ovary, each Ovary takes turns, as one will release an egg one month, while the other takes over for the next month ...

I only ever get pain from my left ovary.. It got me wondering if there was something wrong with my right one so I Googled (as you do!!) and came across quite a few posts from other forums saying that this can be quite normal and doesnt mean there is anything wrong.. The long and short of what I read was that one ovary can go about its business nice and quietly while the other might make a huge song and dance about it. My left one is obviously just an attention seeker!!!!. Anyone else only ever feel pain on one side when ovulating? ...

First Baby Born From Ovary Tissue Frozen During Mothers Childhood | UPRISER
A team of Belgian doctors have managed to restore fertility in a 27-year-old woman using a piece of ovarian tissue that was removed and frozen when she was 13. This is the first time this procedure has worked with non-adult tissue, offering new hope for women who are infertile as a result of medical treatments during their childhood. The case study has been published in the journal Human Reproduction.. This is an important breakthrough in the field because children are the patients who are most likely to benefit from the procedure in the future, said lead author, researcher and gynaecologist Isabelle Demeestere, in a press release. When they are diagnosed with diseases that require treatment that can destroy ovarian function, freezing ovarian tissue is the only available option for preserving their fertility.. At the age of 13, the patient described in the new study underwent chemotherapy so that she could receive a bone marrow transplant from her brother, intended to treat severe ...

Simones Journey : Ovary in distress sending out an SOSSimones Journey : Ovary in distress sending out an SOS
I have been thinking about what to do. Since lufs is my main problem. I would like to ignore the number and focus on using my good ovary and see how the Lupron and G-csf affect my LUFS. Statistically the right ovary goes more often than the left so this may be tricky. I may have to go back on stims to work them both. If nothing makes me rupture then I am done for good. Then if I do rupture but do not have success then I would consider having another surgery and get my ovary cleaned up. I have already had 5 and I really do not want to have another. I honestly do not know if my DH could take another one with the expense, travel, time off, emotions etc ...

Successfully cryo-preserved whole ovary
Before this technology can be used in human preservation the perfusion rates and the levels of anti-coagulant will need to be optimised for different sized ovaries and of course trials on the normality of offspring will be required. Additionally it could also perhaps be applied to the cryo-preservation of other organs and even one day major ones such as kidneys where there are considerable difficulties in storing donated tissue. Although an organ, the ovary is small - though still with multiple cell types and a separate blood supply. So far attempts to freeze and store larger whole organs such as the heart, liver and kidney have proved unsuccessful. The primary challenge with whole organ cryo-preservation is that of preserving an intact vascular system and the Nottingham work, funded by the UKs Medical Research Council - is a major step in the right direction ...

Transformation of human ovarian surface epithelial cells by Kruppel-liTransformation of human ovarian surface epithelial cells by Kruppel-li
We have previously demonstrated that Kruppel-like factor 8 (KLF8) participates in oncogenic transformation of mouse fibroblasts and is highly overexpressed in human ovarian cancer. In this work, we first correlated KLF8 overexpression with the aggressiveness of ovarian patient tumors and then tested if KLF8 could transform human ovarian epithelial cells. Using the immortalized non-tumorigenic human ovarian surface epithelial cell line T80 and retroviral infection, we generated cell lines that constitutively overexpress KLF8 alone or its combination with the known ovarian oncogenes c-Myc, Stat3c and/or Akt and examined the cell lines for anchorage-independent growth and tumorigenesis. The soft agar clonogenic assay showed that T80/KLF8 cells formed significantly more colonies than the mock cells. Interestingly, the cells expressing both KLF8 and c-Myc formed the largest amounts of colonies, greater than the sum of colonies formed by the cells expressing KLF8 and c-Myc alone. These results suggested that

Ovarian transposition is a procedure that can help preserve fertility for female patients requiring radiation in the abdominopelvic region. However, the displacement of ovaries from its original anatomic location can make oocyte retrieval challenging. A 24-year-old nulligravid patient recently diagnosed with colorectal carcinoma [CRC] underwent ovarian transposition prior to radiation. After radiation and chemotherapy, she began in vitro fertilization [IVF] by reproductive endocrinology and infertility physicians. Right ovary demonstrated nonviability due to failed transposition and radiation. Left ovarian oocytes were not able to be harvested due to risk of left kidney puncture via transvaginal ultrasound [TVUS]. Interventional Radiology [IR] was involved and performed a transabdominal ultrasound guided egg retrieval which led to successful IVF. This case highlights the utility of IR-assisted transabdominal ultrasound approach for oocyte retrieval in patients with history of ovarian transposition.

Ecdysteroid Regulation of Ovarian Growth and Oocyte Maturation in the by R. Parthasarathy, Zhentao Sheng et al.Ecdysteroid Regulation of Ovarian Growth and Oocyte Maturation in the by R. Parthasarathy, Zhentao Sheng et al.
Previous studies from our laboratory showed the involvement of juvenile hormone (JH) and ecdysteroid signaling in the regulation of female reproduction in the red flour beetle, Tribolium castaneum. JH regulates vitellogenin (Vg) synthesis in the fat body but the role of ecdysteroid signaling is not known. Here, we report on ecdysteroid regulation of ovarian growth and oocyte maturation. Microarray analysis of RNA isolated from ovaries showed the up-regulation of several genes coding for proteins involved in ecdysteroid signaling on the 4th day after female adult eclosion. The functional analyses of genes coding for proteins involved in ecdysteroid and JH signaling pathways by RNA interference (RNAi) revealed that ecdysteroids but not JH regulate ovarian growth and primary oocyte maturation. Ultrastructural studies showed the temporal sequences of key events in oogenesis including the development of primary oocytes, the differentiation and development of follicle epithelial cells, and the formation of

Canonical Wnt signalling in mouse ovarian surface epithelium.OA BiologyCanonical Wnt signalling in mouse ovarian surface epithelium.OA Biology
Introduction. The gonad arises from the thickening of the coelomic epithelium and then commits into the sex determination process. The Wnts are a family of glycoprotein signalling molecules known mostly for the roles they play in embryonic and ovarian development. Canonical Wnt signalling leads to intracellular accumulation of the multifunctional protein β-catenin which can interact with members of the T-cell factor family to modulate gene transcription. In reviewing the current understanding of ovarian surface epithelium development in the literature, we highlight some previous studies and discuss some of the recent mouse models that have contributed to the understanding of ovarian surface epithelium differentiation.. Conclusion. Taking into account the recent emergence of studies examining Wnt signalling in ovary development and ovarian cancer, the current data suggest that mouse ovarian surface epithelium is heterogeneous in Wnt signalling and may contain a population of stem/progenitor ...

Polycystic ovary syndrome | Archives of Disease in ChildhoodPolycystic ovary syndrome | Archives of Disease in Childhood
The symptoms of PCOS often date from adolescence and it is no surprise that polycystic ovaries are commonly found in teenagers with menstrual disturbances and/or hirsutism. The typical biochemical abnormalities are often present but it is important to be aware that, as in adults, serum concentrations of LH or testosterone (even in hirsute subjects) may be normal and should not prohibit the diagnosis of PCOS, which is made, primarily, on clinical and ultrasonographic criteria. Polycystic ovaries can be identified on ultrasound, even in prepubertal children. The prevalence of polycystic ovaries increases throughout puberty, reaching 26% by the age of 15.12 Full expression of clinical and endocrine features of polycystic ovary syndrome depends on the maturational changes in the hypothalamic-pituitary-ovarian axis which occur during normal puberty, notably the influence of gonadotrophins on ovarian steroidogenesis. The presence of polycystic ovaries before the onset of puberty suggests that the ...

Regulated expression of follicle stimulating hormone receptor type III in cancer causing mouse ovarian surface epithelial cellsRegulated expression of follicle stimulating hormone receptor type III in cancer causing mouse ovarian surface epithelial cells
Follicle stimulating hormone (FSH) is known as the key hormone capable of causing proliferation of granulosa cells in the ovary. The classical receptor belongs to the G protein-coupled superfamily and is designated FSHR-1. A variant in the FSH receptor has been shown to be functional in mouse ovaries. The variant receptor is designated as FSHR-3, and when bound by FSH activates a pathway that shares similar characteristics to the growth factor type I receptor pathway, with no increase in cAMP. The FSHR-3 variant activates MAPK upon binding to FSH, and causes proliferation of cells on which it is known to be expressed. For example ID8 mouse ovarian surface epithelium cells (MOSEC), a cell line that when introduced in immunocompetent mice causes tumors similar to human ovarian cancer and which also express FSHR-3, proliferated in response to FSH. The present study explored the potential for decreasing expression of FSHR-3 protein. The RNA interference (RNAi) technique was used to insert small ...

Earlier studies have demonstrated that phenol UDP-glucuronosyltransferase (UGT) activity is up-regulated by pregnant mares serum gonadotropin (PMSG) in rat ovary, but not liver. This phenomenon was investigated in more detail in the present study. Ovaries and livers of immature rats, rats synchronized with respect to their preovulatory and corpus lutealphases by treatment with PMSG, and mature rats hyperstimulated with PMSG were compared. Under all of these conditions, only one immunoreactive band of UGT, shown to be phenol UGT, was detected in the rat ovary. The effects of oestradiol, progesterone and/or human chorionic gonadotropin (hCG) on the level of phenol UGT in immature rat ovary were also examined. Partial up-regulation was caused by progesterone or oestradiol, together with hCG, whereas progesterone or oestradiol alone had no up-regulating effect. Follicle-stimulating hormone also seemed to be required for the up-regulation in ovaries enriched in corpus luteum. The present findings ...

Ovarian follicle activation - WikipediaOvarian follicle activation - Wikipedia
Ovarian follicle activation can be defined as primordial follicles in the ovary moving from a quiescent (inactive) to a growing phase. The primordial follicle in the oocyte is what makes up the pool of follicles that will be induced to enter growth and developmental changes that change them into pre-ovulatory follicles, ready to be released during ovulation. The process of development from a primordial follicle to a pre-ovulatory follicle is called folliculogenesis. Activation of the primordial follicle involves the following: a morphological change from flattened to cuboidal granulosa cells, proliferation of granulosa cells, formation of the protective zona pellucida layer, and growth of the oocyte. It is widely understood that androgens act primarily on preantral follicles and that this activity is important for preantral follicle growth. Additionally, it is thought that androgens are involved in primordial follicle activation. However, the influence of androgens on primordial follicle ...

Experimental evidence showing that no mitotically active female germline progenitors exist in postnatal mouse ovaries | PNASExperimental evidence showing that no mitotically active female germline progenitors exist in postnatal mouse ovaries | PNAS
It has been generally accepted for more than half a century that, in most mammalian species, oocytes cannot renew themselves in postnatal or adult life, and that the number of oocytes is already fixed in fetal or neonatal ovaries. This assumption, however, has been challenged over the past decade. In this study, we have taken an endogenous genetic approach to this question and generated a multiple fluorescent Rosa26rbw/+;Ddx4-Cre germline reporter mouse model for in vivo and in vitro tracing of the development of female germline cell lineage. Through live cell imaging and de novo folliculogenesis experiments, we show that the Ddx4-expressing cells from postnatal mouse ovaries did not enter mitosis, nor did they contribute to oocytes during de novo folliculogenesis. Our results provide evidence that supports the traditional view that no postnatal follicular renewal occurs in mammals, and no mitotically active Ddx4-expressing female germline progenitors exist in postnatal mouse ovaries. ...

Apoplexy of the ovary. - Yoga Its Our Health
Apoplexia of the ovary (apoplexia ovarii) is an acute gynecological disease that results in the rupture of vessels (this may be the vessels of both the ovary itself and the cyst formed), and a sudden hemorrhage develops into the ovarian tissue or into the abdominal cavity.. Anatomy and physiology of ovaries.. The ovaries are a paired organ located on either side of the uterus in a small pelvis. Their average length is 3 cm, the thickness is 1 cm, and the width is 2 cm. But these dimensions are not constant, and vary throughout the month, depending on the phase of the menstrual cycle. Ovaries are female sex glands, they produce sex hormones (progesterone and estrogens), and every month an egg is formed that can give life to a new organism. Ovaries have their own ligaments, with which they attach to the uterus.. The prevalence of the disease.. Apoplexy of the ovary occurs at any age, but most often the gap occurs in women of childbearing period (from 18 to 45 years), because it is at this age that ...

Synchrotron Imaging of Human Ovaries Ex Situ - Full Text View - ClinicalTrials.govSynchrotron Imaging of Human Ovaries Ex Situ - Full Text View - ClinicalTrials.gov
The objective of our research is to determine whether the synchrotron is an effective tool for imaging human ovaries ex situ. Approximately 1 in every 6 women in Canada is affected by infertility; however, the underlying causes remain largely unknown. Imaging techniques are essential for increasing our understanding of normal and abnormal female reproductive biology. At present, ultrasonography is the most commonly-used tool to image human ovaries. However, ultrasonography only allows the detection of structures ≥ 2 mm in size within the ovaries, limiting the ability to detect smaller anatomic details (eg. the eggs and the surrounding cells and follicles or the small fluid filled sacs that contain the eggs). Other limitations of ultrasonography for imaging the ovaries include a limited depth of penetration within the pelvis and the inability to see the ovaries clearly due to bowel activity and/or gas.. The synchrotron has been effectively used for imaging soft tissues, including the breast, ...

Aromatase plays a key role in sex differentiation of gonads. In this study, we cloned the full-length cDNA of ovarian aromatase from protogynous hermaphrodite red-spotted grouper (Epinephelus akaara), and prepared the corresponding anti-EaCyp19a1a antiserum. Western blot and immunofluorescence studies revealed ovary-specific expression pattern of EaCyp19a1a in adults and its dynamic expression change during artificial sex reversal. EaCyp19a1a was expressed by follicular cells of follicular layer around oocytes because strong EaCyp19a1a immunofluorescence was observed in the cells of ovaries. During artificial sex reversal, EaCyp19a1a expression dropped significantly from female to male, and almost no any positive EaCyp19a1a signal was observed in testicular tissues. Then, we cloned and sequenced a total of 1967 bp T-flanking sequence of EaCyp19a1a promoter, and showed a number of potential binding sites for some transcriptional factors, such as SOX5, GATA gene family, CREB, AP1, FOXL1, C/EBP, ...

Hormonal Signals that Regulate Ovarian Differentiation - Northwestern Scholars
DESCRIPTION (provided by applicant): This proposal requests renewal for years 21-25 of the P01 program Hormonal Signals that Regulate Ovarian Differentiation at Northwestern University. The program has a long history of collaborative discovery-based research in the reproductive sciences that has led to numerous scientific breakthroughs over the lifetime of the grant. The major theme of the program is to investigate signaling pathways by which hormones or other regulatory factors act on the ovary to promote steroidogenesis and the maturation of follicles and germ cells necessary to sustain female fertility. To investigate this theme, 3 new research projects are proposed that represent novel and creative research directions inspired by our progress during the last grant period and by our most recent preliminary findings. Project 1 (Kelly Mayo and Teresa Woodruff) focuses on ovarian development and the events that regulate the breakdown of germ cell nests to form the initial pool of primordial ...

The Role of Growth Factors in Ovarian Function and Development | GLOWMThe Role of Growth Factors in Ovarian Function and Development | GLOWM
Transforming growth factor-β (TGF-β) superfamily is a group of about 35 proteins involved in pre- and postnatal physiological processes.56 Members of this superfamily are expressed by oocytes and ovarian somatic cells in key developmental stages.57, 58, 59, 60, 61 Throughout life ovarian follicles leave the resting pool to join the growing pool. The precise mechanism of follicular recruitment is not fully elucidated, however, members of the TGF-β family are involved in the process. Bone morphogenetic proteins (BMP) 7 and 4 promote primordial to primary follicle transition.62 Similarly, anti-Mullerian hormone (AMH), another member of the TGF-β superfamily, is involved in initiation of primordial follicle growth.63 Progression of primary follicles to early antral stage is enhanced by growth and differentiation factor-9 (GDF-9) and BMP-15 of oocyte origin, activins of granulosa origin, and BMP-4 and BMP-7 of thecal origin.61 Antral follicle growth and follicle selection mechanism involves the ...

Ovary - Embryonic Development & Stem Cells - LifeMap DiscoveryOvary - Embryonic Development & Stem Cells - LifeMap Discovery
Clusters of primordial germ cells (PGCs) with somatic cells come closer to form ovigerous cords, which is first discernible in the fetal ovary upon establishment of initial contact between germ cells and somatic cells near the surface of the ovarian epithelium.. The first mechanistic difference between an XX and an XY germ cell in the genital ridge is reactivation of the inactive X in the female PGCs. The XX germ cells continue to divide and then enter meiosis at around E12.5. Subsequently, the female germ cells arrest at the diplotene stage of meiosis I and do not resume meiosis until postnatal ovarian folliculogenesis.. Folliculogenesis: Before formation of an ovarian follicle, oocytes are present within germ cell clusters (cysts or nests). The first stage of ovarian folliculogenesis involves the formation of the primordial follicle, which occurs when oocytes that survive the process of germ cell cluster breakdown are individually surrounded with squamous pre-granulosa cells. This takes place ...

Factors that cause some primordial follicles to enter the growth phase while the others remain quiescent are unknown. The hypothesis was tested that primate primordial follicles can survive and initiate growth in vitro in serum-free medium. Superficial pieces of ovarian cortex, containing mostly primordial follicles, were obtained from baboon fetuses during late gestation and cultured for 0, 2, 4, 7, 10 or 20 days in Waymouth MB 752/1 medium supplemented with insulin, transferrin, selenium, linoleic acid, and bovine serum albumin (ITS +). Histological examination of cortical pieces revealed that after 2 and 4 days in culture, the total number of primordial follicles had decreased by 55 and 76% (P | 0.01) respectively, relative to day 0 of culture. This was associated with a sustained, 5- to 8-fold increase in total primary follicles (P | 0.01) beginning on day 2 of culture. There was also a gradual increase in the total number of early secondary and secondary follicles. The average

Ovaries | SEER TrainingOvaries | SEER Training
Female sex cells, or gametes, develop in the ovaries by a form of meiosis called oogenesis. The sequence of events in oogenesis is similar to the sequence in spermatogenesis, but the timing and final result are different. Early in fetal development, primitive germ cells in the ovaries differentiate into oogonia. These divide rapidly to form thousands of cells, still called oogonia, which have a full complement of 46 (23 pairs) chromosomes. Oogonia then enter a growth phase, enlarge, and become primary oocytes. The diploid (46 chromosomes) primary oocytes replicate their DNA and begin the first meiotic division, but the process stops in prophase and the cells remain in this suspended state until puberty. Many of the primary oocytes degenerate before birth, but even with this decline, the two ovaries together contain approximately 700,000 oocytes at birth. This is the lifetime supply, and no more will develop. This is quite different than the male in which spermatogonia and primary spermatocytes ...

To determine the intracellular gene targets of P4 in non-neoplastic OSE cells, we analyzed changes in gene expression patterns in six independent short-term cultures using genome-wide transcript arrays. We found a highly statistically significant regulation of transcripts involved in cholesterol metabolism. For example, multiple transcripts representing cholesterol-homeostasis genes including HMGCS1, HMGCR, IDI1, FDPS, FDFT1, NSDHL, EBP, DHCR7, INSIG1, FADS1 were upregulated by P4 exposure (Additional File 2). Examination of each experimental pair revealed that the transcriptional activity induced by P4 exposure originated only from three of the six experimental pairs. Re-analysis of these three responder pairs uncovered a functionally uncharacterized gene TMEM97 as the most-responsive transcript which showed a 1.95-fold increase upon P4 exposure. Examination of genome-scale, tissue-specific gene expression levels in the GNF2 database uncovered a strong correlation between TMEM97 and cholesterol ...

The reproductive cycle can be divided into an ovarian cycle and a uterine cycle (compare ovarian histology and uterine histology in the diagram on the right). During the uterine cycle, the endometrial lining of the uterus builds up under the influence of increasing levels of estrogen (labeled as estradiol in the image). Follicles develop, and within a few days one matures into an ovum, or egg. The ovary then releases this egg, at the time of ovulation. After ovulation the uterine lining enters a secretory phase, or the ovarian cycle, in preparation for implantation, under the influence of progesterone. Progesterone is produced by the corpus luteum (the follicle after ovulation) and enriches the uterus with a thick lining of blood vessels and capillaries so that it can sustain the growing fetus. If fertilization and implantation occur, the embryo produces Human Chorionic Gonadotropin (HCG), which maintains the corpus luteum and causes it to continue producing progesterone until the placenta can ...

The present study investigated the efficiency of saline solution and coconut water solution in the preservation of goat preantral follicles enclosed in ovarian tissue, at different temperatures and for different incubation periods. At the slaughterhouse, the ovarian pair was divided into 19 fragments; one ovarian fragment was immediately fixed for histology (control-time zero). The other 18 ovarian fragments were preserved in both solutions at 4ºC, 20ºC or 39ºC for 4 h, 12 h or 24 h. The histological analysis showed that the storage of ovarian fragments in both solutions at 4ºC for up to 24 h kept the percentage of normal preantral follicles similar to the control values. In contrast, preservation at 20°C or 39ºC, in either solution, reduced significantly the percentage of normal preantral follicles compared to the control values, except in saline solution at 20ºC for 4 h or in coconut water solution at 20ºC for 4 h and 12 h. In conclusion, this study shows that both solutions can be ...

I prefer to end my week either on a high note or hell, why not just high.. However, since Im now a responsible adult with a child, Ill be selecting the high note.. There are several tests out there to help physicians determine a womans Ovarian Reserve (cache of eggs). We have the AFC: Antral Follicle Count - Presumably, the number of antral follicles visible on ultrasound is indicative of the relative number of microscopic (and sound asleep) primordial follicles remaining in the ovary. Each primordial follicle contains an immature egg that can potentially develop in the future. In other words, when there are only a few antral follicles visible, there are less eggs remaining as compared to when there are more antral follicles visible. As women age, they have less eggs (primordial follicles) remaining, therefore they have less antral follicles visible on ultrasound. (1). We have the CD3 FSH:. Day 3 Follicle Stimulating Hormone - By measuring a baseline FSH on day 3 of the cycle (we do it on ...

Lipid Cell Tumor of the Ovary: A case report.Lipid Cell Tumor of the Ovary: A case report.
Lipid cell tumors of the ovary are among the rarest of the functional ovarian neoplasms. Recently, authors experienced a case of lipid cell tumor of the left ovary in a 19 year old female, who presented with amenorrhea and hirsutism for 4 years. Grossly, the ovary was well encapsulated, and measured 6.5x6x4.5 cm. Cut surface show homogenous yellowish bulging neoplastic tissue and peritheral displaced normal ovarian tissue. Microscopically, neoplastic cells were composed of rounded and polyhedral cells, arranged in nests seperated by rich vascular networks. On the basis of the authors findings and the evidence available in the literature, we determined this case as ovarian lipid cell tumor. ...

Ovary Cancer | Causes and Home remedy for Ovary Cancer
The risk rises with age, with around nine in 10 women being over 45. There are several other risk factors, the most important being a history in your close family - as 5-10 per cent of women with ovary cancer have inherited a damaged BRCA1 or BRCA2 gene, which makes this cancer more likely. If your mother has had ovary cancer your risk is six times that of the average woman and if your sister has had it your risk is nearly four times the average. If two close relatives have had it, you have a two in five risk of getting it - which is very high, so its essential to see a gynecologist to discuss screening. Sometimes a high risk of both ovary and breast cancers or of ovary and colon cancers, runs in families. ...

the reason why women are different from men, is the inherent chromosome, the external genital organs, centered in the central part of the ovary. because of ovarian hormone secretion diligently, in order to maintain the development of reproductive organs, from the inside to show the feminine. women from birth to old, ovary is not the full role in the play, but she has been in the company, even has quietly to sleep, no function, still stubbornly nest deep in the body, never abandon. the life of a woman is a reduced version of a womans life infants and young children, the children grow up slowly, the ovary is, but at this time the ovary can not secrete hormones, but in the long. generally after the age of 8, the ovary began to produce sex hormones, puberty began to develop, menstruation, and this is the menstrual cycle of ovarian hormones secreted by the changes in the endometrium. women of childbearing age can give birth to life, this stage is also the most exuberant period of ovarian vitality. ...

Mice Give Birth With 3D Printed Ovaries - Nova ScientiaMice Give Birth With 3D Printed Ovaries - Nova Scientia
Science fiction meets biology meets medicine. Researchers at Northwestern University presented findings in April 2016 at the Annual Endocrine Society Meeting where they created a prosthetic ovary using a 3D printer and implanted it into mice. The hope of this seemingly Frankenstein-esque procedure is to be able to provide fertility to woman who have lost the use of their ovaries due to processes such as trauma, chemotherapy, radiation or resection.. The process begins by printing a scaffold out of gelatin (made from animal collagen). What makes this step crucial is related to the physical properties of human ovaries. When eggs mature in the ovaries, they grow. Once the egg is released, the remaining products (corpus luteum) remains behind to secrete hormones to allow for development of the embryo. Therefore, the scaffold cannot be rigid, but allow for expansion and contraction of the eggs. Not only does the scaffold have to house the growing eggs, but there also has to be room for blood vessels ...

Proteins act to preserve fertility in animals - BREVIA
In January 2017, Drs. Donahoe and David Pépin stunned the scientific community with the discovery that AMH/MIS can function both as a contraceptive agent and as an agent which can protect the ovarian reserve during chemotherapy. Their research team showed that MIS can block primordial follicle activation, thereby inhibiting the first step of folliculogenesis and reproduction. Reduction in the number of growing follicles leads to a phenotype of smaller ovaries in the body. This increase in AMH does not reduce the number of primordial follicles, rather it prevents follicular loss. It also can provide contraception without removing reserve oocytes - or immature, female germ cells - during chemotherapy, so natural reproduction can still occur. In mice, treatment with MIS has now been shown to protect the ovarian reserve. As a result, MIS proves to be a reversible contraceptive that functions to mitigate potentially negative effects that chemotherapy may have on mice [7]. Ongoing studies on larger ...
