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.

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 ...

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). ...

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,

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.. ...

The only difference between a woman with one ovary and a woman with both ovaries is that the woman with one ovary may go through menopause sooner. 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.

Management of women with reduced ovarian reserve or poor ovarian response (POR) to stimulation is one of the major challenges in reproductive medicine. 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. This prospective, randomized controlled study included 186 consecutive patients with POR stratified according to the POSEIDON classification group 3 (age | 35, poor ovarian reserve parameters). The participants were randomized to the CoQ10 pre-treatment for 60 days preceding IVF-ICSI cycle or no pre-treatment. The number of high quality embryos was a primary outcome measure. A total of 169

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.. The majority of vertebrate and invertebrate miRNAs identified in this study are not related by sequence, but a few exceptions do exist and are similar to results previously reported for let-7 RNA (8). Sequence analysis of the D. melanogaster miRNAs revealed four such instances of sequence ...

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 ...

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 ...

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 ...

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 ...

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.

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

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 ...

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 ...

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 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 ...

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. ...

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 ...

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, ...

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 ...

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 ...

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

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 ...

Though the authors insisted that instructions for collecting and submitting your urine are simple, modern readers might disagree. I feel amazing 90 of the time, there is that 10 when Im very uncomfortable but that is bound to happen, I have a human living inside me, haha. There may also be a change in mood, a feeling of fatigue, or simply somehow feeling different. Understand that youre not alone. Looking back now, after having information about HELLP syndrome (Ive spent hours reading about it on internet websites) I had a lot of corpus luteal cyst right ovary during pregnancy of this that could have possibly allowed me to prolong my delivery had it been caught. Waiting at least a week after a missed period may give you the most accurate result. In some women, more frequent urination starts even before they miss the period.

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 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. ...

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. ...

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 ...

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 ...
