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.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.Pregnanediol: An inactive metabolite of PROGESTERONE by reduction at C5, C3, and C20 position. Pregnanediol has two hydroxyl groups, at 3-alpha and 20-alpha. It is detectable in URINE after OVULATION and is found in great quantities in the pregnancy urine.Ovulation: The discharge of an OVUM from a rupturing follicle in the OVARY.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.Clomiphene: A triphenyl ethylene stilbene derivative which is an estrogen agonist or antagonist depending on the target tissue. Note that ENCLOMIPHENE and ZUCLOMIPHENE are the (E) and (Z) isomers of Clomiphene respectively.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.Time-to-Pregnancy: Time interval, or number of non-contraceptive menstrual cycles that it takes for a couple to conceive.Infertility, Female: Diminished or absent ability of a female to achieve conception.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.Follicle Stimulating Hormone, Human: A major gonadotropin secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and the LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. The alpha subunit is common in the three human pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.Oligomenorrhea: Abnormally infrequent menstruation.Hirsutism: A condition observed in WOMEN and CHILDREN when there is excess coarse body hair of an adult male distribution pattern, such as facial and chest areas. It is the result of elevated ANDROGENS from the OVARIES, the ADRENAL GLANDS, or exogenous sources. The concept does not include HYPERTRICHOSIS, which is an androgen-independent excessive hair growth.Amenorrhea: Absence of menstruation.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.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.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.Ovulation Induction: Techniques for the artifical induction of ovulation, the rupture of the follicle and release of the ovum.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.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.Menstrual Cycle: The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.Electrocoagulation: Procedures using an electrically heated wire or scalpel to treat hemorrhage (e.g., bleeding ulcers) and to ablate tumors, mucosal lesions, and refractory arrhythmias. It is different from ELECTROSURGERY which is used more for cutting tissue than destroying and in which the patient is part of the electric circuit.Fertility Agents, Female: Compounds which increase the capacity to conceive in females.Menstruation: The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.Postpartum Period: In females, the period that is shortly after giving birth (PARTURITION).Estrus: The period in the ESTROUS CYCLE associated with maximum sexual receptivity and fertility in non-primate female mammals.Animals, Suckling: Young, unweaned mammals. Refers to nursing animals whether nourished by their biological mother, foster mother, or bottle fed.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.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.Pregnancy: The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.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.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.Gonadotropin-Releasing Hormone: A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, LUTEINIZING HORMONE and FOLLICLE STIMULATING HORMONE. GnRH is produced by neurons in the septum PREOPTIC AREA of the HYPOTHALAMUS and released into the pituitary portal blood, leading to stimulation of GONADOTROPHS in the ANTERIOR PITUITARY GLAND.Pregnancy Rate: The ratio of the number of conceptions (CONCEPTION) including LIVE BIRTH; STILLBIRTH; and fetal losses, to the mean number of females of reproductive age in a population during a set time period.Hypothalamo-Hypophyseal System: A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.Privacy: The state of being free from intrusion or disturbance in one's private life or affairs. (Random House Unabridged Dictionary, 2d ed, 1993)Confidentiality: The privacy of information and its protection against unauthorized disclosure.Computer Security: Protective measures against unauthorized access to or interference with computer operating systems, telecommunications, or data structures, especially the modification, deletion, destruction, or release of data in computers. It includes methods of forestalling interference by computer viruses or so-called computer hackers aiming to compromise stored data.Obstetrics: A medical-surgical specialty concerned with management and care of women during pregnancy, parturition, and the puerperium.Gynecology: A medical-surgical specialty concerned with the physiology and disorders primarily of the female genital tract, as well as female endocrinology and reproductive physiology.Electronic Mail: Messages between computer users via COMPUTER COMMUNICATION NETWORKS. This feature duplicates most of the features of paper mail, such as forwarding, multiple copies, and attachments of images and other file types, but with a speed advantage. The term also refers to an individual message sent in this way.Food Dispensers, Automatic: Mechanical food dispensing machines.Editorial Policies: The guidelines and policy statements set forth by the editor(s) or editorial board of a publication.Authorship: The profession of writing. Also the identity of the writer as the creator of a literary production.Periodicals as Topic: A publication issued at stated, more or less regular, intervals.Postal Service: The functions and activities carried out by the U.S. Postal Service, foreign postal services, and private postal services such as Federal Express.Internet: A loose confederation of computer communication networks around the world. The networks that make up the Internet are connected through several backbone networks. The Internet grew out of the US Government ARPAnet project and was designed to facilitate information exchange.Endometrial Neoplasms: Tumors or cancer of ENDOMETRIUM, the mucous lining of the UTERUS. These neoplasms can be benign or malignant. Their classification and grading are based on the various cell types and the percent of undifferentiated cells.Ultrasonography, Interventional: The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.Insulin Resistance: Diminished effectiveness of INSULIN in lowering blood sugar levels: requiring the use of 200 units or more of insulin per day to prevent HYPERGLYCEMIA or KETOSIS.Menarche: The first MENSTRUAL CYCLE marked by the initiation of MENSTRUATION.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. Etiologies include genetic defects, autoimmune processes, chemotherapy, radiation, and infections.Hypothalamic Diseases: Neoplastic, inflammatory, infectious, and other diseases of the hypothalamus. Clinical manifestations include appetite disorders; AUTONOMIC NERVOUS SYSTEM DISEASES; SLEEP DISORDERS; behavioral symptoms related to dysfunction of the LIMBIC SYSTEM; and neuroendocrine disorders.Biological Science Disciplines: All of the divisions of the natural sciences dealing with the various aspects of the phenomena of life and vital processes. The concept includes anatomy and physiology, biochemistry and biophysics, and the biology of animals, plants, and microorganisms. It should be differentiated from BIOLOGY, one of its subdivisions, concerned specifically with the origin and life processes of living organisms.Audiovisual Aids: Auditory and visual instructional materials.
Histopathological findings of the ovaries in anovulatory women. (1/209)Wedge resection of the ovary was carried out in 45 anovulatory women to study the correlation between the degree of disturbance of ovulation and the histopathological findings. Polycystic ovary was always found in patients with anovulatory cycles. The ovaries in grade 1 amenorrhea showing withdrawal bleeding in response to gestagen alone belonged to the nonspecific type, polycystic type and sclerotic type. These histological changes were relatively mild in many cases. The ovaries in grade 2 amenorrhea showing withdrawal bleeding in response to estrogen and gestagen but not to gestagen alone belonged to the non-specific type, polycystic type, sclerotic type, atrophic type and streak type. Even within the same histological entity, the histological findings of the ovaries were more pronounced in grade 2 amenorrhea than in grade 1 amenorrhea. The patients with primary amenorrhea had only hypoplastic and aplastic ovaries with marked histological abnormalities. (+info)
Effects of time of suckling during the solar day on duration of the postpartum anovulatory interval in Brahman x Hereford (F1) cows. (2/209)Previously published reports have indicated that postpartum anovulatory intervals can be markedly reduced and rebreeding performance enhanced in Bos taurus cows by eliminating nighttime suckling. We sought to confirm this hypothesis by examining the effects of day, nighttime, and ad libitum suckling on suckling behavior of calves, duration of the postpartum anovulatory interval, and pregnancy rates in 45 fall-calving Brahman x Hereford (F1) cows. Beginning on d 9 to 12 postpartum, calves were removed from lactating cows from 0700 to 1900 (Night-Suckled, n = 15) or from 1900 to 0700 (Day-Suckled, n = 15), or remained with their dams continuously (Ad Libitum-Suckled, n = 15). Cows in each group were maintained with fertile Angus bulls from d 10 postpartum until the first normal luteal phase or 100 d postpartum, whichever occurred first. Cows were observed for estrous behavior twice daily, and jugular blood samples were collected twice weekly for the determination of serum progesterone concentration. Mean number of suckling episodes per 24 h was greater (P < .0001) for the Ad Libitum-Suckled group than either Night- or Day-Suckled groups (5.9+/-.42 vs 3.8+/-.14, and 3.9+/-.32, respectively). Hourly analysis of suckling episodes in the Ad Libitum group indicated that they were not skewed toward a particular period, with suckling occurring at a periodicity of 4 to 6 h. Intervals to the first rise in progesterone > or = 1 ng/mL (32+/-2.5, 32+/-4.5, and 31+/-1.7 d, respectively), first normal luteal phase (38+/-3.1, 38+/-3.8, and 37+/-2.5 d, respectively), and first estrus (43+/-3.5, 40+/-3.9, and 36+/-1.1 d, respectively) did not differ (P > .05) among the three groups. Similarly, cumulative pregnancy rates within 100 d after calving did not differ (P > .05). These results in Bos indicus x Bos taurus (F1) cattle do not support the previous conclusions in Bos taurus that eliminating nighttime suckling reduces the postpartum anovulatory interval. (+info)
Anovulations in an ovary during two menstrual cycles enhance the pregnancy potential of oocytes matured in that ovary during the following third cycle. (3/209)The aim of this study was to test whether ovulation from an ovary affects the health of oocytes from dominant follicles in that ovary two cycles later. A total of 80 women each with two intact ovaries underwent 270 treatment cycles (155 natural cycles and 115 clomiphene citrate cycles) all showing unilateral ovulation. The results from the in-vitro fertilization (IVF) treatment were grouped according to whether ovulation (O) or anovulation (A) (no ovulation) was observed in the ovary with dominant follicle during the treatment cycle in the previous two cycles: O-O, A-O, O-A and A-A (previous second cycle-previous first cycle). The rate of pre-embryo formation in A-A was significantly higher than that of O-A. The pregnancy rate in A-A (29%) was also higher than those of O-A (13%), A-O (9%) and O-O (5%). These rates increased from O-O to A-A as the number of previous ovulations in an ovary decreased. The presence of a corpus luteum and/or a dominant follicle is likely to exert local negative effects on the health of the oocyte contained in the follicle selected to ovulate up to two cycles later. Anovulations in an ovary for two menstrual cycles may therefore provide improved conditions for the development of a healthier oocyte with an increased pregnancy potential. (+info)
Nutritionally induced anovulation in beef heifers: ovarian and endocrine function preceding cessation of ovulation. (4/209)Angus x Hereford heifers were used to determine endocrine and ovarian function preceding nutritionally induced anovulation. Six heifers were fed to maintain body condition score (M), and 12 heifers were fed a restricted diet (R) until they became anovulatory. Starting on d 13 of an estrous cycle, heifers were given PGF2alpha every 16 d thereafter to synchronize and maintain 16 d estrous cycles. Ovarian structures of M and R heifers were monitored by ultrasonography daily from d 8 to ovulation (d 1 of the subsequent cycle) until R heifers became anovulatory. Concentrations of LH and FSH were quantified in serum samples collected every 10 min for 8 h on d 2 and 15 (48 h after PGF2alpha), and estradiol and IGF-I were quantified in daily plasma samples from d 8 to 16 during the last ovulatory cycle (Cycle -2) and the subsequent anovulatory cycle (Cycle -1). During the last two cycles before anovulation, M heifers had 50% larger (P < .0001) ovulatory follicles than R heifers and 61% greater (P < .0001) growth rate of the ovulatory follicles. There was a treatment x cycle x day effect (P < .001) for concentrations of estradiol. The preovulatory increase in estradiol occurred in the R and M heifers during Cycle -2 but only in M heifers during Cycle -1. A treatment x cycle x day effect (P < .05) influenced LH concentrations. During Cycle -2, LH concentrations were similar for M and R heifers, but during Cycle -1, M heifers had greater LH concentrations than did R heifers. Concentrations of FSH were greater (P < .05) in R than M heifers after induced luteolysis when R heifers failed to ovulate. There was a treatment x cycle interaction (P < .05) for IGF-I concentrations, and M heifers had 4.7- and 8.6-fold greater IGF-I concentrations than did R heifers during Cycle -2 and -1, respectively. We conclude that growth rate and diameter of the ovulatory follicle, and concentrations of LH, estradiol, and IGF-I are reduced before the onset of nutritionally induced anovulation in beef heifers.

Induction of ovulation by Sairei-to for polycystic ovary syndrome patients. (5/209)In anovulatory patients ovulation is usually induced by clomiphene citrate (CC) or gonadotropin therapy, but in the case of polycystic ovary syndrome (PCOS), diagnosed by the presence of several micropolycysts in the ovaries and a high LH/FSH ratio in the serum, CC is only minimally effective, and side effects are often a problem with gonadotropin therapy. In the present study we administered a Chinese herbal medicine Sairei-to which appears to have a steroidal effect in anovulatory PCOS patients. As a result of the treatment, serum LH and the LH/FSH ratio significantly decreased (P<0.01) and the ovulatory rate was 70.6%. Serum testosterone levels were within normal limits before the treatment, and did not significantly change during the treatment. Sairei-to may therefore be useful for the treatment of anovulation in PCOS patients. (+info)
Twice daily suckling but not milking with calf presence prolongs postpartum anovulation. (6/209)Two experiments were conducted to determine whether milking beef cows two or five times daily in the presence or absence of their own nonsuckling calves would alter postpartum interval to first ovulation. Multiparous Angus x Hereford cow-calf pairs were assigned randomly between 13 and 18 d postpartum to treatments for 4 wk. In Exp. 1, pairs were assigned to six treatments: 1) calf was weaned permanently from its dam (CW; n = 9); 2) same as CW, but dam was milked twice daily (CW+2xM; n = 9); 3) calf was present continuously with its dam but restricted from contact with the udder (CR; n = 9); 4) same as CR, but dam was milked twice daily (CR+2xM; n = 9); 5) same as CR, but calf was allowed to suckle twice daily (CR+2xS; n = 8); and 6) calf was present continuously with its dam and suckled ad libitum (CP; n = 9). The interval from onset of treatments to first postpartum ovulation was shorter (P<.05) in the CW (14.1+/-3.1 d), CR (14.2+/-3.1 d), CW+2xM (13.0+/-3.1 d), and CR+2xM (17.2+/-3.1 d) than in the CP (34.7+/-3.1 d) and CR+2xS (33.9+/-3.3 d) treatments. Daily milk yield during treatment was greater (P<.01) for CR+2xM cows (7.1+/-.6 kg) than for CW+2xM cows (3.5+/-.6 kg). In Exp. 2, cow-calf pairs were assigned to three treatments: 1) CR+2xM (n = 10); 2) same as CR+2xM but cows were milked five times daily (CR+5xM; n = 10); or 3) CP (n = 10). The interval to first postpartum ovulation was shorter (P<.05) in the CR+2xM (23.6+/-3.5 d) and CR+5xM (26.1+/-3.7 d) treatments than in the CP (37.7+/-3.7 d) treatment. Daily milk yield during treatment was greater (P<.05) for CR+5xM cows (7.7+/-.6 kg) than for CR+2xM cows (6.4+/-.6 kg) by 17%. We conclude that suckling twice daily was sufficient to prolong postpartum anestrus as much as suckling ad libitum. Furthermore, milk removal by suckling, but not by milking two or five times daily, even in the presence of the cow's own nonsuckling calf, is essential to prolong postpartum anovulation. (+info)
Adipocyte insulin action following ovulation in polycystic ovarian syndrome. (7/209)The role of anovulation and insulin resistance in the pathogenesis of polycystic ovarian syndrome (PCOS) remains to be determined. The aim of this study was to investigate whether the metabolic abnormality of insulin resistance in PCOS reflects, rather than causes, the ovarian dysfunction. Eight subjects with classical PCOS were studied on two occasions. Adipocyte insulin sensitivity together with hormonal and metabolic changes were investigated in patients with PCOS following prolonged amenorrhoea and then again in the early follicular phase after ovulation. Insulin receptor binding in amenorrhoeic subjects with PCOS was low at 0.78 +/- 0.08% and this increased to 1.18 +/- 0.19% after an ovulatory cycle (P < 0.05). Maximal insulin stimulated 3-O-methylglucose uptake was 0.70 +/- 0. 14 during amenorrhoea and increased to 1.08 +/- 0.25 pmol/10 cm(2) cell membrane (P < 0.05). Plasma testosterone fell (4.0 +/- 0.4 to 2. 3 +/- 0.2 nmol/l; P < 0.001), luteinizing hormone fell (17.6 +/- 2.3 to 6.7 +/- 0.8 IU/l; P < 0.001) but plasma insulin concentrations remained unchanged following ovulation (14.6 +/- 1.9 and 15.7 +/- 3. 8 pmol/l during amenorrhoea and after ovulation respectively). The results of this study suggest that chronic anovulation per se appears to modify the factors contributing to cellular insulin resistance seen in PCOS. (+info)
Neonatal handling induces anovulatory estrous cycles in rats. (8/209)Since previous work has shown that stimulation early in life decreases sexual receptiveness as measured by the female lordosis quotient, we suggested that neonatal handling could affect the function of the hypothalamus-pituitary-gonadal axis. The effects of neonatal handling on the estrous cycle and ovulation were analyzed in adult rats. Two groups of animals were studied: intact (no manipulation, N = 10) and handled (N = 11). Pups were either handled daily for 1 min during the first 10 days of life or left undisturbed. At the age of 90 days, a vaginal smear was collected daily at 9:00 a.m. and analyzed for 29 days; at 9:00 a.m. on the day of estrus, animals were anesthetized with thiopental (40 mg/kg, ip), the ovaries were removed and the oviduct was dissected and squashed between 2 glass slides. The number of oocytes of both oviductal ampullae was counted under the microscope. The average numbers for each phase of the cycle (diestrus I, diestrus II, proestrus and estrus) during the period analyzed were compared between the two groups. There were no significant differences between intact and handled females during any of the phases. However, the number of handled females that showed anovulatory cycles (8 out of 11) was significantly higher than in the intact group (none out of 10). Neonatal stimulation may affect not only the hypothalamus-pituitary-adrenal axis, as previously demonstrated, but also the hypothalamus-pituitary-gonadal axis in female rats. (+info)
Gonadotrophin Dosage Using a Threshold Nomogram for Ovulation Induction in WHO Group II Anovulatory Infertility - Full Text...
Ovulation disorders are a common cause of infertility in women. Most of these women can be classified as World Health Organization (WHO) Group II anovulatory patients as they have irregular or absent menstrual cycles but normal serum concentrations of follicle stimulation hormone (FSH) and estradiol.. The purpose of this study is to optimize the low-dose-step-up protocol traditionally used for ovulation induction with follicle-stimulating hormone (FSH) in women with anovulatory infertility WHO Group II.. Previous studies have established that menstrual cycle history, mean ovarian volume and BMI are significant predictors of FSH threshold dose in women with anovulatory infertility WHO Group II undergoing ovulation induction (Nyboe Andersen et al., 2008). A FSH dosage nomogram has been constructed based on these variables.. The aim of this study is to evaluate the clinical use of the nomogram in order to test the use of the variables to determine whether an individualized starting dose of FSH can ...

TY - JOUR. T1 - Hormonal profiles in anovulatory patients treated with gonadotropins and synthetic luteinizing hormone releasing hormone. AU - Crosignanl, Pier Giorgio. AU - Trojsi, Letizia. AU - Attanasio, Antonio. AU - Tonani, Emiliano. AU - Donini, Pietro. PY - 1975. Y1 - 1975. N2 - Ten patients with hypothalamic anovulation were treated with a "retard" preparation of synthetic luteinizing hormone releasing hormone (LHRH) after an HMG stimulation in order to induce ovulation and pregnancy. Four of the patients ovulated after intramuscular administration of the LHRH preparation. This study suggests that it is possible to induce ovulation with LHRH in patients pretreated with HMG, and that LHRH has advantages over HCG since it does not induce hyperstimulation even in the presence of exaggerated follicular growth. Nevertheless, the optimal conditions for the use and monitoring of LHRH treatment have yet to be clarified.. AB - Ten patients with hypothalamic anovulation were treated with a ...
Volume 5, Chapter 22. Anovulation
Failure of the female gonads to discharge ova in a monthly, repetitive manner is referred to as oligo-ovulation. Failure to discharge ova over a prolonged period, usually defined as longer than 3 months, is called anovulation. Anovulation is the normal state for both young women and those beyond their reproductive years. Between 16 and 40 years of age it is, in the absence of pregnancy, an abnormal state and a common gynecologic problem. When experienced over a long period, this condition may be associated with endometrial carcinoma and premature osteoporosis. Among infertile women, anovulation can be found approximately 30% of the time. Most anovulatory women experience either irregular vaginal bleeding or amenorrhea. However, anovulation and amenorrhea are not mutually inclusive states. The intermittent shedding of endometrium (i.e., menses) requires that there be sufficient circulating estrogen to promote tissue proliferation. Ovulation is not a requisite precondition for the production of ...
anovulatory cycles - Med Notes
Isolation of estrogen during anovulatory cycles are usually reduced in comparison with the norm.But because of different genesis anovulatory cycles, estrogen character selection may be different.Their excretion can be monotonous at a relatively high level.Spotting at the appropriate time of menstruation, occur at the same time due to the mechanism of intermittent bleeding in the intact hormone levels ( «break though» phenomenon).But in addition to this type of urinary estrogens, are anovulatory cycles with fluctuating level of their allocation;while there is a rather long persisting maximum release estrogen at mid-cycle (as opposed to the normal cycle when the ovulatory peak lasts only 1 to 2 days) before menstruation and their separation decreases, which reflects the development of the follicle atresia and then it without breaking.Isolation in all cases pregnanediol anovulatory cycles is low (not higher than 2.1 mg), which indicates the absence of progesterone production by the corpus ...

Anovulatory Cycle Explained: What Is It and How to Prevent It? - Mira Fertility Tracker
Identification of differentially expressed genes in pathways of cerebral neurotransmission of anovulatory mice. | GMR |...
Polycystic ovary syndrome is the classic example of loss of functional cyclicity and anomalous feedback. In this case, the excessive extra-glandular production and conversion of androgens to estrogens are the pathophysiological basis of the chronic anovulation. The literature describes an experimental model of the polymicrocystic ovary in obese diabetic mice with insulin resistance. The fact that these animals exhibit obesity, insulin resistance, and infertility demonstrates their skill as an experimental model for polycystic ovary. A recent study using long protocol for up to 40 weeks showed that anovulatory and obese mice transplanted with adipose tissue from animals with normal weight have multiple changes in their phenotype. These changes include reduction of body weight, prevention of obesity, insulin level normalization, and insulin tolerance tests, preventing the elevation of steroids and especially the reversal of fertility restoration with anovulation. Considering that there are close ...

Anovulation Follow-up: Further Outpatient Care
TTC... new of anovulatory cycle - BabyCenter
My husband and I decided to start TTC. I did a 21 day progesterone test and it came back anovulatory. I told my doc my periods are average 25 days (always 24, 25, or 26 days) and she did not want to move the date of the 21 day test. I have moderate to heavy periods every month, consistently. Very discouraged with the news. Even more discouraged there was limited information provided with the suggestion of OPK (ovulation predictor kit) kits x 2 months then start clomid. Any advice from anyone??

Clinical Effects of Clomiphene in Anovulation : Obstetrics & Gynecology
June 2009 | Leave the lights on
According to the Pope Paul VI institute, a major proponent of natural infertility treatment, so-called "natural reproductive technology" has higher success rates than IVF for various infertility diagnoses. These results are both statistically significant (i.e. not due to chance) and personally significant (i.e. theyre a lot higher). For example, for a diagnosis of endometriosis, IVF has a success (pregnancy) rate of about 21%, while natural reproductive treatment has a success rate of about 57%. It reports a 37% success rate for tubal occlusion compared to IVFs 27%. The whopping 82% success rate reported for natural fertility treatment of anovulation (not producing mature eggs) may be due to straightforward treatment of the most obvious cause of anovulation, hormonal insufficiency (although I am speculating here ...
Why could malnutrition cause anovulation? - Answered by top doctors on HealthTap
Article - INER - Planificarea naturală a concepției
Again and again, there is the statement that the temperature measurement is used to distinguish between an ovulatory and an anovulatory cycle and that the temperature is rising after ovulation [6: p.35, p.92] [12: p.72] [15: p 29] [30: p.84] [40: S.454] [43: p.133] [44: p.38] First, it should be pointed out that a biphasic cycle is not evidence that an ovulation has taken place. Therefore, an ovulatory cycle cant be determined in this way. Moreover it is to state that the waking temperature can rise before ovulation, which is described as early as 1950 in the work of Buxton and Engle . Rauscher (1954, 1958) [32,34] has this to say: "The increase in temperature can occur within a period ranging from some days before ovulation to 4, in extreme cases even up to 6 days after ovulation" This is not just a theoretical question, but it also serves for the understanding of the so-called "premature temperature rise" (Rötzer, 1979) [37,38,39]; an explanation for this lies in the obligatory ...

Can You Get Pregnant Naturally in your 50s | ConceiveEasy.com
Women who are approaching age 50 are most likely already in peri menopause, and some women are already in full blown menopause. If a woman has not used up all of her eggs by this point, the eggs that remain are most likely not viable, and if a pregnancy were to occur, it would most likely result in miscarriage or a baby with birth defects. Many women around age 50 also begin to have anovulatory cycles, where no egg is released at all. Women who do get pregnant after age 40 have around a 50 percent chance of conceiving in the first trimester, and the pregnancies that result after this age are not usually the most healthy.. ...

The Rotunda Ramblings: Clomiphene Citrate
Clomiphene Citrate is the most used and abused medication for infertility treatment. It was introduced to the clinical market in 1967 and almost immediately replaced the surgical procedure - wedge resection of the ovaries - for primary treatment of anovulation in patients with polycystic ovarian disease (PCOD). Clomiphene Citrate is still widely used by gynecologists for that purpose and others. It is important to remember that proper use of the medication will usually yield gratifying results while expanding its use to lesser indications may be counterproductive and often results in unsuccessful outcomes. Clomiphene Citrates best and most common indication is for induction of ovulation in euestrogenic, normoprolactinemic, and anovulatory patients. The majority of these patients will have PCOD, which is a clinical diagnosis of chronic anovulation with symptoms and signs of Hyperandrogenism. The definition implies that there is adequate endogenous estrogen production and that hyperprolactinemia ...

AsianAmerican Summit: Proceedings: AsianAmerican 2008 Hawaii
Aygul Demirol, MD Women Health, Infertility and IVF Center, Ankara/Turkey. Anovulation or oligo-ovulation is one of the main characteristics of the polycystic ovary syndrome (PCOS). When patients with PCOS complain of infertility, ovulation induction is the appropriate treatment. Various drugs and treatment regimens have been used for ovulation induction in PCOS, but none of them has become unique in achieving the goals. The reason for the existence of so many treatment regimens is related to the multifactorial pathophysiology of PCOS and consequently to the variability in clinical manifestations and the hormonal milieu.. Anovulation is a common cause of infertility. About 70% of infertile women presenting with oligomenorrhoea or amenorrhoea exhibit normal FSH and estradiol (E2) concentrations (World Health Organization [WHO], Type-2 anovulation). Normogonadotropic anovulatory infertility can be identified in 18-25% of the couples presenting with infertility. Polycystic ovary syndrome (PCOS) ...
Infertility in polycystic ovary syndrome - Wikipedia
Infertility in polycystic ovary disease (PCOS) is a hormonal imbalance in women that is thought to be one of the leading causes of female infertility. Polycystic ovary syndrome causes more than 75% of cases of anovulatory infertility. Not all women with PCOS have difficulty becoming pregnant. For those who do, anovulation is a common cause. The mechanism of this anovulation is uncertain, but there is evidence of arrested antral follicle development, which, in turn, may be caused by abnormal interaction of insulin and luteinizing hormone (LH) on granulosa cells. Endocrine disruption may also directly decrease fertility, such as changed levels of gonadotropin-releasing hormone, gonadotropins (especially an increase in luteinizing hormone), hyperandrogenemia, and hyperinsulinemia. Gonadotropins are released by gonadotroph cells in pituary gland, and these cells appear to harbor insulin receptors, which are affected by elevated insulin levels. A reason that insulin sensitizers work ...
La Consulta Semanal
The cardinal clinical features of PCOS are hirsutism and menstrual irregularity from anovulation. Obesity occurs in approximately 50% of hyperandrogenic anovulatory women, some of whom also have non-insulin-dependent diabetes mellitus. Underlying these clinical findings are several biochemical abnormalities, including LH hypersecretion, hyperandrogenism, acyclic estrogen production, decreased SHBG capacity, and hyperinsulinemia, all of which contribute to increased ovarian production of androgens, particularly T. A fundamental mechanism of ovarian hyperandrogenism in PCOS is LH hypersecretion. Whether the central nervous system is a possible locus for initiating LH hypersecretion remains unclear, because exaggerated LH secretion is temporarily reversed by induced ovulatory cycles or physiologic luteal concentrations of progesterone. On the other hand, desynchronization of pulsatile LH secretion from sleep in girls with PCOS and an exaggerated (e.g., masculinized) early LH response to GnRHa ...

How to recognize PCOS: results of a web-based survey at IVF-worldwide.com - WebSM
Abstract This retrospective evaluation of a web-based survey posted from 1 to 30 September 2010 was to determine which diagnostic tools physicians are currently utilizing to diagnose polycystic ovary syndrome (PCOS). Responses from 262 IVF centres in 68 countries are included in the study. Providers used various diagnostic criteria to diagnose PCOS, including the Rotterdam criteria (82%), National Institutes of Health criteria (8%), Androgen Excess Society 2006 criteria (3%) and other classification systems (7%). Many providers utilized diagnostic tools not necessarily included in traditional classification systems: 58% of respondents evaluated LH/FSH ratio in addition to androgen concentrations to define patients with PCOS; physicians also commonly obtain measurement of anti-M llerian hormone (22%) and impaired glucose tolerance (74%) in diagnosing PCOS. Many respondents (64%) felt that polycystic-appearing ovaries on ultrasound with anovulation and a normal serum prolactin should be adequate ...
Risk Factors for the Development of Haemorrhagic Anovulatory Follicles in the Mare - Cuervo-Arango - 2008 - Reproduction in...
Haemorrhage into the dominant follicle during the reproductive season is a subtle but definitive cause of infertility in the mare population. This condition however can be of high relevance for an individual in which its incidence is abnormally high. Little is known about the nature and factors affecting the incidence of haemorrhagic anovulatory follicles (HAFs) in the mare. The objectives of the study were to define and characterize the ultrasonographic development and incidence of HAFs and to investigate possible risk factors influencing its occurrence. Detailed reproductive and ultrasound records of seven mares studied during their entire reproductive lives (,10 years and 612 oestrous cycles) were analysed retrospectively and computed into a statistical mixed model. Of all animal studied, two mares were found to have an unusually high incidence of HAFs of approximately 25%. Time of season and use of induction treatments (Cloprostenol) were found to influence its incidence. It appears that ...

How Do I Know I Ovulated? The Signs of Fertility - www.early-pregnancy-tests.com
Answer: Perhaps the only sure way to determine if ovulation has taken place is verification through ultrasound at your doctors office. Unless you have confirmed fertility issues (anovulation, amenorrhea, etc), ultrasounding ova is likely not on your to-do list. Fortunately, there are a number of natural fertility signs and indicators that can tell you, with a very high degree of likelihood, that you have indeed ovulated (or are about to!). First off, simply exhibiting a regular menstrual cycle (lasting around a month) is the first solid indicator of a healthy cycle and suggests a strong likelihood you ovulate. Also, there are other important signs that tell you when you ovulate each month, the very signs that constitute the intricate facets of your fertility chart.Lets look at the ovulation symptoms below that can either confirm you have already ovulated this cycle - or help you anticipate imminent fertility….

Hyperprolactinemia-induced ovarian acyclicity is reversed by kisspeptin administration
Hyperprolactinemia is the most common cause of hypogonadotropic anovulation and is one of the leading causes of infertility in women aged 25-34. Hyperprolactinemia has been proposed to block ovulation through inhibition of GnRH release. Kisspeptin neurons, which express prolactin receptors, were recently identified as major regulators of GnRH neurons. To mimic the human pathology of anovulation, we continuously infused female mice with prolactin. Our studies demonstrated that hyperprolactinemia in mice induced anovulation, reduced GnRH and gonadotropin secretion, and diminished kisspeptin expression. Kisspeptin administration restored gonadotropin secretion and ovarian cyclicity, suggesting that kisspeptin neurons play a major role in hyperprolactinemic anovulation. Our studies indicate that administration of kisspeptin may serve as an alternative therapeutic approach to restore the fertility of hyperprolactinemic women who are resistant or intolerant to dopamine agonists ...

PCOS (Polycystic Ovary Syndrome) and Hypothyroidism - Stop The Thyroid Madness
In most cases, it appears so. Newer research has shown that women with PCOS are three times more likely (and some say four times more likely) to also have Hashimotos Disease. Women in internet forums have also been surprised to discover that most of them shared the two conditions.. PCOS and hypothyroidism have many symptoms in common, such as "anovulation" i.e. menstration without releasing an oocyte (egg cell). Some propose this is the cause of PCOS if anovulation is long term with its related low progesterone. Other symptoms the two conditions share are: insulin resistance, blood sugar problems leading to diabetes, high cholesterol levels, heavy periods, weight gain (obesity), hair loss and ovarian cysts.. In fact, we have seen patients who were erroneously diagnosed with PCOS when they really had thyroid disease. Read this gals story here.. Other causes of PCOS can include excess insulin which might boost androgen production, low grade inflammation (which is common with those who have ...

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in reproductive women and is characterized by polycystic ovaries, hyperandrogenism and chronic anovulation. Abnormal folliculogenesis is considered as a common characteristic of PCOS. Our aim is to identify the altered circRNA expression profile in exosomes isolated from follicular fluid (FF) of PCOS patients to investigate the molecular function of exosomal circRNA, as a vital mediator in follicular microenvironment, in the aetiology and pathobiology of PCOS. In this study, the circRNA expression profile of FF exosomes were compared between PCOS and control patients by RNA sequencing (N=5 vs 5). Sixteen circRNAs showed significantly different expression. GO and KEGG pathway analyses indicated that their parental genes were enriched in PCOS-related pathways, including ovarian steroidogenesis, aldosterone synthesis and secretion, and Jak-STAT signaling.

What does ovulation induction mean?
This mix is designed to address the causes of Poly Cystic Ovarian Syndrome (PCOS), which are excessive amounts of male hormones (androgens), produced by the ovaries and adrenal glands resulting from the release of excessive luteinizing hormone (LH) by the anterior pituitary gland or through high levels of insulin in the blood (hyperinsulinaemia). The mix also alleviates the symptoms, oligomenorrhea, amenorrhoea, chronic anovulation (lack of ovulation), hirsutism, male pattern baldness in women and acne, obesity, depression and a deepening of voice.
Stress and Reproductive Challenges - Kristy Allan Kinesiology
Emotional stress, oxidative stress and inflammation all play a role in the pathogenesis of PCOS. Stress has been linked to aggravate the metabolic abnormalities present in PCOS.. PCOS, characterised by chronic anovulation and hyperandrogenism, has many features of metabolic syndrome and can be considered a metabolic disease. Insulin resistance presents in the vast majority (60-90%) of obese patients and (25-45%) of lean patients. A dietary trigger such as glucose is capable of inciting oxidative stress and inflammatory response in women with PCOS. Increased abdominal fat is also a factor and this inflamed adipose tissue contributes to the inflammatory load in the disorder. Elevated insulin levels contribute to or cause the abnormalities seen in the hypothalamus - pituitary - ovarian axis that lead to PCOS.. In women, small amounts of testosterone are produced by the ovaries and adrenal glands. Even a slight increase in testosterone production can disrupt the balance of hormones and cause ...

For women with PCOS who are actively trying to conceive, it is advised to consult with a fertility specialist, since more than 95% of women with PCOS do not ovulate regularly, or have regular menstrual cycles and therfore experience difficulty when trying to conceive.. In anovulatory cycles, ovarian follicles fail to mature fully and release eggs. Treatment to promote the recruitment and release of the egg is required (ovulation induction).. For the optimal management of PCOS, we must also look at any coexisting causes of infertility and assess tubal function and semen analysis. We then manage ovulation induction through close monitoring and a time line.. Oral fertility medications like clomiphene (Clomid or Serophene) or letrozole (Femara), which have been available for many decades, continue to be widely used to produce an ovarian follicle containing an egg..

Can Being Overweight Make it Harder to Get Pregnant? | ConceiveEasy.com
If your BMI is over 40 then you are morbidly obese and you should not at all even consider conceiving if your weight is that high at all. Chances are if your BMI is over 40, you will not be able to conceive at all since you likely have anovulatory cycles. But that again means that if you have a BMI of 31 to 35, then you are not out of the woods- you are still obese and it is in your best interest, as well as the interest of your unborn baby to end up at least at an acceptably overweight level at the worst. The kind of complications that an obese pregnant woman can face are:. Hyperemesis gravidarum - This condition involves extreme nausea and vomiting which oftentimes requires hospitalization and can last through the entire pregnancy. Even though many babies born to mothers who had this condition end up healthy because of the fact that they were able to get their nutrients via IVs or from TPN, it is a miserable condition to go through and there are other risks that you could face from it like ...
What is Ovulation Induction (OI)? - Definition from FertilitySmarts
Mitochondrial dysfunction in oocytes of obese mothers: transmission to offspring and reversal by pharmacological endoplasmic...
Obese women have a well-known risk for anovulation and reduced pregnancy rates (Gesink Law et al., 2007; Rittenberg et al., 2011); our data now shows that concerted ER stress responses in both granulosa and cumulus cells, impaired matrix protein production and high levels of spindle abnormalities are likely to be responsible for reduced ovulation and poor fertilization rates in obese animals. Most alarmingly, however, following conception, maternal obesity is also associated with adiposity in offspring (Ruager-Martin et al., 2010), suggesting that metabolic change can be transmitted through the generations in a self-perpetuating cycle that is set by maternal over-nutrition. Our findings confirm that fetal growth is altered in obese mothers and further demonstrate that this developmental trajectory is established during oocyte development and maturation. We show the existence of a mechanism whereby nutrition in mothers, in this case obesity, can alter the embryo and fetal mitochondrial ...
Cell-cell interactions play crucial roles in the maintenance of tissue homeostasis, a loss of which often leads to varying diseases, including cancer. Here, we report that uncontrolled PI3K activity within oocytes irreversibly transforms granulosa cells (GC), causing GC tumors (GCT) through perturbed local cell-communication. Previously, we reported reproductive phenotypes of transgenic mice, in which expression of constitutively active mutant PI3K was induced in primordial oocytes by Gdf9-iCre. The transgenic mice (Cre+) demonstrated severe ovarian phenotypes, including the overgrowth of excess ovarian follicles and anovulation. Surprisingly, the Cre+ mice became cachectic by postnatal day 80 due to bilateral GCT. Although GCT cells proliferated independently of oocytes, local interactions with mutant PI3K-positive oocytes during early folliculogenesis were essential for the GC transformation. Growing GCT cells expressed high levels of inhibin βA and nuclear SMAD3, and the proliferation rate ...

Atherosclerosis is a disease which involves the gradual buildup of plaque in the arteries which eventually leads to narrowing. This prevents adequate blood supply to the affected area and leads to characteristic symptoms. When this condition affects the arteries in the legs, it reduces the amount of oxygen supplied to the muscles of the leg, causing muscle cramps when walking in its early stages. As the disease progresses, it can cause toe discoloration and foot ulcers. This condition is called peripheral arterial disease (PAD) or peripheral vascular disease (PVD). If it affects the arteries in the neck, this reduces the amount of oxygen-rich blood reaching the brain. This condition is called carotid artery disease (CAD) and may lead to a stroke. Risk factors for the development of atherosclerosis include smoking, hypertension, diabetes mellitus, and high cholesterol.. The following is a list of symptoms of PAD:. ...
