    Context: Adolescents are at high risk for menstrual dysfunction. The diagnosis of anovulatory disorders that may have long-term health consequences is too often delayed. Evidence Acquisition: A review of the literature in English was conducted, and data were summarized and integrated from the author's perspective. Main Findings: Normal adolescent anovulation causes only minor menstrual cycle irregularity: most cycles range from 21–45 days, even in the first postmenarcheal year, 90% by the fourth year. Approximately half of symptomatic menstrual irregularity is due to neuroendocrine immaturity, and half is associated with increased androgen levels. The former is manifest as aluteal or short/deficient luteal phase cycles and usually resolves spontaneously. The latter seems related to polycystic ovary syndrome because adolescent androgen levels are associated with adult androgens and ovulatory dysfunction, but data are sparse. Obesity causes hyperandrogenemia and, via unclear mechanisms, seems to suppress LH; it may mimic polycystic ovary syndrome. The role of pubertal insulin resistance in physiological adolescent anovulation is unclear. High-sensitivity gonadotropin and steroid assays, the latter by specialty laboratories, are necessary for accurate diagnosis of pubertal disorders. Polycystic ovaries are a normal ultrasonographic finding in young women and are associated with nearly 2-fold increased anti-Müllerian hormone levels. Oral contraceptives are generally the first-line treatment for ongoing menstrual dysfunction, and the effects of treatment are similar among preparations. Conclusions: Menstrual cycle duration persistently outside 21–45 days in adolescents is unusual, and persistence ≥ 1 year suggests that disordered hypothalamic-pituitary-gonadal function be considered. Research is needed on the mechanisms and prognosis of adolescent anovulation. PMID:23913942

    Although minerals are linked to several reproductive outcomes, it is unknown whether dietary minerals are associated with ovulatory function. We hypothesised that low intakes of minerals would be associated with an increased risk of anovulation. We investigated associations between dietary mineral intake and both reproductive hormones and anovulation in healthy women in the BioCycle Study, which prospectively followed up 259 regularly menstruating women aged 18-44 years who were not taking mineral supplements for two menstrual cycles. Intakes of ten selected minerals were assessed through 24-h dietary recalls at up to four times per cycle in each participant. Oestradiol, progesterone, luteinising hormone (LH), follicle-stimulating hormone (FSH), sex-hormone-binding globulin and testosterone were measured in serum up to eight times per cycle. We used weighted linear mixed models to evaluate associations between minerals and hormones and generalised linear models for risk of anovulation. Compared with Na intake ≥1500 mg, Na intake <1500 mg was associated with higher levels of FSH (21·3 %; 95 % CI 7·5, 36·9) and LH (36·8 %; 95 % CI 16·5, 60·5) and lower levels of progesterone (-36·9 %; 95 % CI -56·5, -8·5). Na intake <1500 mg (risk ratio (RR) 2·70; 95 % CI 1·00, 7·31) and Mn intake <1·8 mg (RR 2·00; 95 % CI 1·02, 3·94) were associated with an increased risk of anovulation, compared with higher intakes, respectively. Other measured dietary minerals were not associated with ovulatory function. As essential minerals are mostly obtained via diet, our results comparing insufficient levels with sufficient levels highlight the need for future research on dietary nutrients and their associations with ovulatory cycles.

    Full Text Available Polycystic ovary syndrome (PCOS is a prevalent endocrine disorder and the most common cause of female infertility. However, its etiology and underlying mechanisms remain unclear. Here we report that a transgenic obese mouse (Mito-Ob developed by overexpressing prohibitin in adipocytes develops polycystic ovaries. Initially, the female Mito-Ob mice were equally fertile to their wild-type littermates. The Mito-Ob mice began to gain weight after puberty, became significantly obese between 3-6 months of age, and ∼25% of them had become infertile by 9 months of age. Despite obesity, female Mito-Ob mice maintained glucose homeostasis and insulin sensitivity similar to their wild-type littermates. Mito-Ob mice showed morphologically distinct polycystic ovaries and elevated estradiol, but normal testosterone and insulin levels. Histological analysis of the ovaries showed signs of impaired follicular dynamics, such as preantral follicular arrest and reduced number, or absence, of corpus luteum. The ovaries of the infertile Mito-Ob mice were closely surrounded by periovarian adipose tissue, suggesting a potential role in anovulation. Collectively, these data suggest that elevated estradiol and obesity per se might lead to anovulation and polycystic ovaries independent of hyperinsulinemia and hyperandrogenism. As obesity often coexists with other abnormalities known to be involved in the development of PCOS such as insulin resistance, compensatory hyperinsulinemia and hyperandrogenism, the precise role of these factors in PCOS remains unclear. Mito-Ob mice provide an opportunity to study the effects of obesity on anovulation and ovarian cyst formation independent of the major drivers of obesity-linked PCOS.

    Within colonies of Damaraland mole-rats (Cryptomys damarensis), anovulation in non-reproductive females is thought to play an important role in maintaining reproductive skew. Pituitary sensitivity and ovarian structure were examined in three groups of females that differed with respect to their social environment and breeding status to determine whether anovulation is due to inhibitory social cues or is merely the result of a lack of copulatory stimulation. The contribution of gonadal steroid negative feedback to neuroendocrine differences in the reproductive systems of the respective groups was also investigated. LH secretion after a 0.5 micrograms GnRH challenge in females that had been removed from the presence of the breeding individuals for at least 6 months (removed non-reproductive females) was significantly higher than in non-reproductive females in the colony, but significantly lower than in reproductive females. In both removed non-reproductive females and reproductive females, corpora lutea were observed in ovaries of seven of eight females, indicating that ovulation occurs spontaneously in subordinate females on removal from the breeding pair. Circulating progesterone concentrations in removed non-reproductive females were significantly higher than in non-reproductive females, indicating that circulating progesterone is not responsible for infertility in non-reproductive females. Indeed, after hystero-ovariectomy, reproductive females continued to show significantly greater GnRH-stimulated LH secretion than non-reproductive females. Thus, differential inhibition of gonadotrophin secretion in breeding and non-breeding females occurs independently of gonadal steroids. It is concluded that female Damaraland mole-rats are spontaneous ovulators and that anovulation results from inhibitory social cues within the colony, not a lack of copulatory stimulation. Since non-reproductive females are infertile, inhibition of the hypothalamo-pituitary-gonadal axis has

    Objective To compare previously used algorithms to identify anovulatory menstrual cycles in women self-reporting regular menses. Design Prospective cohort study Setting Western New York Study participants 259 healthy, regularly menstruating women followed for one (n=9) or two (n=250) menstrual cycles (2005–2007). Intervention(s) None. Main Outcome Measure(s) Prevalence of sporadic anovulatory cycles identified using eleven previously defined algorithms that utilize estradiol, progesterone, and luteinizing hormone (LH) concentrations. Result(s) Algorithms based on serum LH, estradiol, and progesterone levels detected a prevalence of anovulation across the study period of 5.5% to 12.8% (concordant classification for 91.7% to 97.4% of cycles). The prevalence of anovulatory cycles varied from 3.4% to 18.6% using algorithms based on urinary LH alone or with the primary estradiol metabolite, estrone-3-glucuronide (E3G), levels. Conclusion(s) The prevalence of anovulatory cycles among healthy women varied by algorithm. Mid-cycle LH surge urine-based algorithms used in over-the-counter fertility monitors tended to classify a higher proportion of anovulatory cycles compared to luteal phase progesterone serum-based algorithms. Our study demonstrates that algorithms based on the LH surge, or in conjunction with E3G, potentially estimate a higher percentage of anovulatory episodes. Addition of measurements of post-ovulatory serum progesterone or urine pregnanediol may aid in detecting ovulation. PMID:24875398

    Stress has been identified as a potential trigger for reproductive dysfunctions, but the psycho-physiological pathway behind the effect of stress on ovulation remains unexplored. The present research work highlights the plausible mechanism of psychological stress on ovulation in mice by targeting superoxide dismutase (SOD), an enzyme involved in ovulation. For this, three consecutive studies were carried out. The first study aimed to determine the effect of psychological stress induced change in cortisol level, behavioral parameters and normal estrous cyclicity. The effect on mRNA expression of SOD subtypes, follicular growth in histological sections of ovaries and the difference in oocyte quality and number, upon superovulation were assessed in the subsequent studies. The results indicate that psychological stress model causes an increase in cortisol level (p⩽0.05) with development of anhedonia, depression and anxiety. An irregular estrous cycle was observed in stressed mice with an upregulation in mRNA expression of SOD subtypes. Histological sections revealed an increase in atretic antral follicle with an impaired follicular development. Moreover, immature oocytes were obtained from superovulated stressed mice. The study concludes that psychological stress results in anovulation which may be due to increase in cortisol level and SOD activity in stressed mice. Copyright © 2015 Elsevier Inc.

    To evaluate rates of presumptive anovulation in eumenorrheic adolescents and young adults with moderate to severe primary dysmenorrhea and those without primary dysmenorrhea. Participants completed luteinizing hormone surge ovulation predictor test kits. Anovulatory cycles were defined by never receiving a positive result before the next menstrual period; participants were grouped as anovulatory if they experienced at least 1 anovulatory cycle during study participation. Participants rated daily level of menstrual pain on a 0-10 numeric rating scale. A university-based clinical research laboratory. Thirty-nine adolescents and young adults (ages 16-24) with primary dysmenorrhea and 52 age-matched control girls. Rates of presumptive anovulation. One hundred sixty-eight cycles were monitored, 29.8% (N = 50) of which were anovulatory (37.1% [39/105] vs 17.5% [11/63] of cycles in control and dysmenorrhea groups, respectively). During study participation, control girls were significantly more likely to have had at least 1 anovulatory cycle than were girls with primary dysmenorrhea (44.2% [23/52] vs 17.9% [7/39] of participants, respectively; P  .05). Our data support previous findings of increased rates of ovulation in primary dysmenorrhea. However, menstruation after anovulatory cycles can be as painful as menstruation after ovulatory cycles. These data support the idea that regular menses do not necessarily indicate that a normal ovulatory cycle has occurred. Previous implications that ovulation is necessary for the development of substantial menstrual pain are incomplete. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

    Background: Clinicians often recommend limiting caffeine intake while attempting to conceive; however, few studies have evaluated the associations between caffeine exposure and menstrual cycle function, and we are aware of no previous studies assessing biological dose via well-timed serum measurements. Objectives: We assessed the relation between caffeine and its metabolites and reproductive hormones in a healthy premenopausal cohort and evaluated potential effect modification by race. Design: Participants (n = 259) were followed for ≤2 menstrual cycles and provided fasting blood specimens ≤8 times/cycle. Linear mixed models were used to estimate associations between serum caffeine biomarkers and geometric mean reproductive hormones, whereas Poisson regression was used to assess risk of sporadic anovulation. Results: The highest compared with the lowest serum caffeine tertile was associated with lower total testosterone [27.9 ng/dL (95% CI: 26.7, 29.0 ng/dL) compared with 29.1 ng/dL (95% CI: 27.9, 30.3 ng/dL), respectively] and free testosterone [0.178 ng/mL (95% CI: 0.171, 0.185 ng/dL) compared with 0.186 ng/mL (95% CI: 0.179, 0.194 ng/dL), respectively] after adjustment for age, race, percentage of body fat, daily vigorous exercise, perceived stress, depression, dietary factors, and alcohol intake. The highest tertiles compared with the lowest tertiles of caffeine and paraxanthine were also associated with reduced risk of anovulation [adjusted RRs (aRRs): 0.39 (95% CI: 0.18, 0.87) and 0.40 (95% CI: 0.18, 0.87), respectively]. Additional adjustment for self-reported coffee intake did not alter the reproductive hormone findings and only slightly attenuated the results for serum caffeine and paraxanthine and anovulation. Although reductions in the concentrations of total testosterone and free testosterone and decreased risk of anovulation were greatest in Asian women, there was no indication of effect modification by race. Conclusion: Caffeine intake

    In many countries, clomifene citrate is the treatment of first choice in women with normogonadotropic anovulation (ie, absent or irregular ovulation). If these women ovulate but do not conceive after several cycles with clomifene citrate, medication is usually switched to gonadotrophins, with or without intrauterine insemination. We aimed to assess whether switching to gonadotrophins is more effective than continuing clomifene citrate, and whether intrauterine insemination is more effective than intercourse. In this two-by-two factorial multicentre randomised clinical trial, we recruited women aged 18 years and older with normogonadotropic anovulation not pregnant after six ovulatory cycles of clomifene citrate (maximum of 150 mg daily for 5 days) from 48 Dutch hospitals. Women were randomly assigned using a central password-protected internet-based randomisation programme to receive six cycles with gonadotrophins plus intrauterine insemination, six cycles with gonadotrophins plus intercourse, six cycles with clomifene citrate plus intrauterine insemination, or six cycles with clomifene citrate plus intercourse. Clomifene citrate dosages varied from 50 to 150 mg daily orally and gonadotrophin starting dose was 50 or 75 IU daily subcutaneously. The primary outcome was conception leading to livebirth within 8 months after randomisation defined as any baby born alive after a gestational age beyond 24 weeks. Primary analysis was by intention to treat. We made two comparisons, one in which gonadotrophins were compared with clomifene citrate and one in which intrauterine insemination was compared with intercourse. This completed study is registered with the Netherlands Trial Register, number NTR1449. Between Dec 8, 2008, and Dec 16, 2015, we randomly assigned 666 women to gonadotrophins and intrauterine insemination (n=166), gonadotrophins and intercourse (n=165), clomifene citrate and intrauterine insemination (n=163), or clomifene citrate and intercourse (n=172).

    Evidence suggests that increased gut permeability may be associated with polycystic ovary syndrome (PCOS). Human zonulin is currently the only physiological mediator known to reversibly regulate gut permeability by disassembling intestinal tight junctions. So far, no data on serum zonulin levels in patients with PCOS are available. This study aimed to determine circulating serum zonulin levels in women with PCOS and discuss the relationship between zonulin, insulin resistance, and menstrual disorders in this group. A case-control study. The study includes 78 women recently diagnosed with PCOS and 63 age-matched healthy controls recruited. Serum zonulin levels were determined by ELISA. Insulin resistance was assessed by homeostasis model assessment of insulin resistance (HOMA-IR) and Matsuda and DeFronzo's insulin sensitivity index (ISI). PCOS women had higher serum zonulin levels (P=0.022). After adjustment for age and BMI, zonulin levels significantly correlated with HOMA-IR and ISI. Furthermore, PCOS women with more severe menstrual disorders had significantly higher zonulin levels and displayed an inverse correlation between zonulin and the number of menstrual cycles per year (r=-0.398, Pzonulin, a biomarker for gut permeability, is increased in PCOS women and correlates with insulin resistance and severity of menstrual disorders. It suggests that alterations in gut permeability may play a role in the pathophysiology of PCOS, and serum zonulin might be used as a biomarker for both risk stratification and therapeutic outcomes in PCOS women. © 2015 European Society of Endocrinology.

    The purpose of this study was to evaluate the effectiveness and endocrine response of oral contraceptive ovarian suppression followed by clomiphene citrate in patients who previously were clomiphene citrate resistant. Forty-eight patients from a private tertiary infertility clinic were assigned randomly prospectively to either group 1 (oral contraceptive/clomiphene citrate), which received continuous oral contraceptives followed by clomiphene citrate, or to group 2 (control) received no treatment in the cycle before clomiphene citrate treatment. On day 3, 17 beta-estradiol, follicle-stimulating hormone, luteinizing hormone, and androgens were assayed before and after treatment. Follicle growth, ovulation, and pregnancy were evaluated. The Student t test and analysis of variance were used for statistical significance. The oral contraceptive/clomiphene citrate group had a significantly higher percentage of patients who ovulated and of ovulatory cycles and pregnancies. Significantly lower levels of 17 beta-estradiol, luteinizing hormone, and androgen levels were seen in the oral contraceptive/clomiphene citrate group, with no significant changes in group 2. Suppression of the ovary with oral contraceptives results in excellent rates of ovulation and pregnancy in patients who previously were resistant to clomiphene citrate. The decreases in ovarian androgens, luteinizing hormone, and 17 beta-estradiol may be responsible for the improved response.

To recover reproduction functionality, recommended therapies for ovarian induction involve injections of FSH and LH medications. Objective: Since important differences exist between recombinant and urinary gonadotropin therapies in terms of efficacy and cost, the objective of this study was to develop a cost-effectiveness model to compare recombinant FSH (rFSH + recombinant LH (rLH and highly purified human menopausal gonadotropin (HP-HMG. Methods: A Markov model was developed, considering three cycles of therapy; probability of pregnancy and miscarriage were considered, and the efficacy was evaluated in terms of pregnancy occurrence. The perspective of the model was that of the Italian Health Service, so only direct cost (drugs, specialist visits, patient examinations, and hospitalizations were included. Results: rFSH + rLH is associated with a higher total cost (€3,453.50 and higher efficacy (0.87 compared with HP-HMG (€2,719.70 and 0.50. rFSH + rLH generated an incremental cost effectiveness ratio equal to €2,007.30 compared to HP-HMG; the average cost per pregnancy is estimated to be €3,990.00 for recombinant strategy and €5,439.80 for urinary strategy. Results of probabilistic sensitivity analysis were consistent with the abovementioned findings. Conclusion: Despite the higher acquisition cost in comparison to HP-HMG, rFSH + rLH resulted in a higher pregnancy rate, which makes it the recommended choice when considering cost-effectiveness of LH in supporting FSH-induced follicular gonadotropins in hypogonadotropic hypogonadal women.

    Full text. In order to evaluate the profile of the sex steroids gonadotropin and prolactin in polycystic ovarian syndrome (POS), 24 patients with POS were studied and compared with 20 normal women during the early follicular phase of the menstrual cycle. Radioimmunoassay techniques for androstenedione (A) and estrone (E 1 ) were standardized for the purpose of the study. Androstenedione and estrone were extracted from plasma with ethyl ether. The assays were maintained in equilibrium and the labelled hormone-antibody complex was then separated from the free hormone using dextran charcoal. The sensitivity of the method was 6.8 pg/tube for A and 3.7 pg/tube for E 1 . Nonspecific binding ws 3.4 for A and 3.3 for E 1 . The interessay error at the D50 level was 15.6 for A and 8.6 for E 1 . Patients with POS had significantly higher basal levels of LH, A, T E 1 and PRL and similar FSH and DHEA-S levels when compared with normal women. The LH/FSH ratio was significantly elevated and the A/T ratio was significantly decreased. The A/E 1 and T/E 2 ratios were elevated and the E 1 /E 2 was decreased, although the differences were not statistically significant. A positive correlation between A and E 1 was observed in patients with POS. In view of the above data, it was concluded that: the quality control parameters of the radioimmunoassay for A and E 1 standardized in the present study are considered satisfactory, and the assay could be used for diagnosis and research; the patients with POS have a different sex steroid and gonadotropin profile when compared normal women during the early follicular phase of the menstrual cycle

    Full text. In order to evaluate the profile of the sex steroids gonadotropin and prolactin in polycystic ovarian syndrome (POS), 24 patients with POS were studied and compared with 20 normal women during the early follicular phase of the menstrual cycle. Radioimmunoassay techniques for androstenedione (A) and estrone (E{sub 1}) were standardized for the purpose of the study. Androstenedione and estrone were extracted from plasma with ethyl ether. The assays were maintained in equilibrium and the labelled hormone-antibody complex was then separated from the free hormone using dextran charcoal. The sensitivity of the method was 6.8 pg/tube for A and 3.7 pg/tube for E{sub 1}. Nonspecific binding ws 3.4 for A and 3.3 for E{sub 1}. The interessay error at the D50 level was 15.6 for A and 8.6 for E{sub 1}. Patients with POS had significantly higher basal levels of LH, A, T E{sub 1} and PRL and similar FSH and DHEA-S levels when compared with normal women. The LH/FSH ratio was significantly elevated and the A/T ratio was significantly decreased. The A/E{sub 1} and T/E{sub 2} ratios were elevated and the E{sub 1}/E{sub 2} was decreased, although the differences were not statistically significant. A positive correlation between A and E{sub 1} was observed in patients with POS. In view of the above data, it was concluded that: the quality control parameters of the radioimmunoassay for A and E{sub 1} standardized in the present study are considered satisfactory, and the assay could be used for diagnosis and research; the patients with POS have a different sex steroid and gonadotropin profile when compared normal women during the early follicular phase of the menstrual cycle

In current study, efforts have been made to study the effect of Nasya and Matra Basti on anovulation (Beeja Dushti). Ovulation is under the control of Vata. Narayana Taila is attributed for its effect in Vandhyatva. 24 patients of female infertility having anovulatory factor, being diagnosed by Trans-Vaginal Sonography (TVS) for 2 consecutive cycles were divided in two groups. Patients in Group A (n = 12) administered the drug through Nasya and in Group B (n = 12) through Matra Basti. Ovulation occurred 36.36% of patients in group A and 66.16% of patients group B. Matra Basti showed better results than Nasya group on anovulation. PMID:24049410

    Abstract Background Female mice and rats injected with estrogen perinatally become anovulatory and develop follicular cysts. The current consensus is that this adverse response to estrogen involves the hypothalamus and occurs because of an estrogen-induced alteration in the GnRH delivery system. Whether or not this is true has yet to be firmly established. The present study examined an alternate possibility in which anovulation and cyst development occurs through an estrogen-induced disruptio...

Irregular menstrual cycles, reduced spontaneous and assisted fertility and an increased risk of miscarriage are risks associated with obesity that are often overlooked. Excessive weight and central distribution of body fat are both related to an increased risk of normogonadotrophic anovulation. Weight loss can re-establish ovulation in obese anovulatory patients or improve their response to ovulation induction. However, ev...

Treatment of anovulation is aimed at induction of ovulation. In women with clomiphene-citrate resistant WHO group II anovulation, one of the treatment options is ovulation induction with exogenous follicle-stimulating hormone (FSH or follitropin. FSH is derived from urine or is produced as recombinant FSH. Two forms of recombinant FSH are available – follitropin alpha and follitropin beta. To evaluate the efficacy, safety, costs and acceptability of recombinant FSH, we performed a review to compare recombinant FSH with urinary-derived FSH products. Follitropin alpha, beta and urinary FSH products appeared to be equally effective in terms of pregnancy rates. Patient safety was also found to be comparable, as the incidence of side effects including multiple pregnancies was similar for all FSH products. In practice follitropin alpha and beta may be more convenient to use due to the ease of self-administration, but they are also more expensive than the urinary products.Keywords: follitropin apha, follitropin beta, urinary gonadotropins, polycystic ovary syndrome

  3. Health and fertility in World Health Organization group 2 anovulatory women.

    Science.gov (United States)

    2012-01-01

    Disruption of ovulation occurs in different types of clinical infertility. The World Health Organization (WHO) has provided a classification of ovulation disorders. This review focuses on WHO group 2 anovulation. Searches were performed in Medline/PubMed and EMBASE. Each subject summary was presented to the European Society of Human Reproduction and Embryology (ESHRE) Workshop Group, where omissions or disagreements were resolved by discussion. Disorders resulting in ovulatory disturbances are a relatively common cause of infertility. They occur most frequently in the context of WHO group 2 anovulation as reflected, for example, in the polycystic ovary syndrome (PCOS). The aetiology of PCOS remains unclear but evidence exists for a multifactorial origin with a genetic predisposition. Women with PCOS show an increased time to pregnancy but their eventual family size is not necessarily reduced. Also their frequency of miscarriage does not appear increased. Clomiphene citrate is still the first-line treatment in subfertile anovulatory patients with PCOS, with gonadotrophins and laparoscopic ovarian surgery as second-line options. Aromatase inhibitors show promising results. Long-term health risks in patients with WHO group 2 anovulation demand their general health be monitored, even after their reproductive needs have been fulfilled. Metabolic and cardiovascular risk prevention in women with PCOS should start as early as possible. It is not easy to analyse the possible role of PCOS, independent of obesity, metabolic syndrome, insulin resistance and diabetes, on long-term health.

  4. Genetic ancestry affects the phenotype of normogonadotropic anovulatory (WHOII) subfertility.

    Normogonadotropic (World Health Organization category II) anovulation is the most frequent cause of reduced fertility. Anovulation is associated with endocrine changes, i.e. hyperandrogenism, obesity, and insulin resistance. However, the phenotype is notoriously heterogeneous, depending on population characteristics and diagnostic criteria. Our objective was to study the phenotype of normogonadotropic anovulatory women among various ethnic subgroups that coexist in an urban community (The Netherlands). Moreover, we studied whether genetic ancestry testing can be used to identify bio-geographic ancestry and predict the phenotype of individual patients. A standardized clinical and endocrine examination was performed in 1517 normogonadotropic anovulatory women. Bio-geographic ancestry was ascertained by questionnaire and genetic testing (637 cases), using a set of 10 previously validated ancestry informative markers. Subgroups constituted individuals from northwestern European (n = 774), Mediterranean European (north of Sahara and Middle East, n = 220), African (n = 111), Southeast Asian (n = 53), and Hindustani (n = 83) origin. Phenotypic differences included fasting insulin levels, androgen levels, and the frequency of hyperandrogenism (ranging from 76% in Mediterranean-European women to 41% in northwestern European women). Genetic ancestry testing was able to identify population structure on a continental level, i.e. European, African and Southeast Asian descent. We did not observe improved informativeness when genotype data were added to the prediction model. Population differences add to the phenotype of normogonadotropic anovulation and need to be taken into account when evaluating the individual patient. Although effective on a continental level, the present set of ancestry markers was not sufficiently effective to describe all ethnic variation in the phenotype of anovulatory subfertility.

    The polycystic ovary syndrome (PCOS) is a common and complex disease with unclear pattern of inheritance, characterized by an androgen excess, while hyperinsulinemia and insulin resistance (IR) are common features of the syndrome. The angiotensin I converting enzyme (ACE) insertion (I)/deletion (D) gene polymorphism was proved to be involved in many pathophysiological conditions, including hypertension and IR. The purpose of this study was to evaluate the involvement of the ACE gene polymorphism in the pathogenesis of PCOS. In a case-control association study involving 801 PCOS women and 266 healthy controls, hormonal determinations and ACE polymorphism genotyping were performed. The PCOS women were classified into three groups: Group A presented biochemical hyperandrogenism, combined with anovulation and polycystic ovarian morphology; Group B, clinical hyperandrogenism combined with anovulation and polycystic ovarian morphology; and Group C, chronic anovulation and polycystic ovarian morphology. A significant increase in the frequency of the DI genotype of the ACE polymorphism was detected in PCOS women as a whole (P=0.035), in PCOS Group A (P=0.039) and Group B (P=0.010), while there was no difference in Group C (P=0.939). Significant difference was also observed in hyperandrogenic PCOS women as a whole (Group A+B) (P=0.017). The II genotype was positively correlated with HOMA-IR and QUICKI and with fasting insulin and glucose/insulin ratio in these groups. The association study of the ACE I/D polymorphism in PCOS women demonstrates an increase in the DI genotype incidence and an association of the II genotype with IR.

    The first menstrual cycles following menarche are often caracterized by irregular and/or heavy bleeding. The adolescent patient may be worried by these episodes of bleeding. In 50-80% of cases these are anovulatory bleeding due to the immaturity of the gonadotrophic axis. Nevertheless pathologies such as von Willebrand disease, genital infection, polycystic ovary syndrom, eating disorders, a tumor or a pregnancy may be diagnosed by bleeding abnormalities. The challenge for the physician is to distinguish between bleeding abnormalities secondary to anovulation and pathologies where investigations and specific follow-up is mandatory. Adolescents who experience abnormal bleeding must be counceled according to their perceptions and expectations.

    Polycystic ovary syndrome (PCOS) is the common endocrine disorder of reproductive age women which is characterized by hyperandrogenism, chronic anovulation, and increased risk for infertility, endometrial cancer, developing metabolic dysfunction (type II diabetes, dyslipidemia), hypertension and heart disease. The syndrome is also associated with some skin disorders: hirsutismus, alopecia androgenetica and acne. The successful dermatologic therapy requires the holistic diagnosis of the women with skin disorders described above and use the antiandrogenic treatment with conventional methods and laser depilation in hirsutismus. In this paper we present literature studies and our own experiences.

  9. Role of metformin for ovulation induction in infertile patients with polycystic ovary syndrome (PCOS): a guideline.

    Science.gov (United States)

    2017-09-01

    Metformin alone compared with placebo increases the ovulation rate in women with polycystic ovary syndrome (PCOS) but should not be used as first-line therapy for anovulation because oral ovulation induction agents such as clomiphene citrate or letrozole alone are much more effective in increasing ovulation, pregnancy, and live-birth rates in women with PCOS. There is fair evidence that metformin alone does not increase rates of miscarriage when stopped at the initiation of pregnancy and insufficient evidence that metformin in combination with other agents used to induce ovulation increases live-birth rates.

    Full Text Available Being either underweight or overweight can affect a woman's fertility. Irregular menstrual cycles, reduced spontaneous and assisted fertility and an increased risk of miscarriage are risks associated with obesity that are often overlooked. Excessive weight and central distribution of body fat are both related to an increased risk of normogonadotrophic anovulation. Weight loss can re-establish ovulation in obese anovulatory patients or improve their response to ovulation induction. However, even a small amount of weight loss (5% may improve fertility. Men who are overweight or obese have significantly lower sperm counts than men of normal weight.

    1998-02-01

    This study was undertaken to assess the causes and treatments of menorrhagia in adolescents hospitalized for this menstrual disorder. A retrospective chart review was performed of all adolescents adolescents with 46 admissions for menorrhagia were identified. The average age of menarche was 12.9 years and the average age at admission was 15.9 years. Nineteen adolescents had significant medical diseases. For the 46 admissions, causes of menorrhagia were anovulation (21), hematologic disease (15), chemotherapy-related (5), and infections (5). Transfusions of blood products were performed in 28 of the admissions. Treatments included oral contraceptive pills or progestins (30), intravenous conjugated estrogens (8), antibiotics (4), immune gammaglobulin (3), DDAVP (3), and prednisone (1). Twelve surgical procedures were performed, including eight dilatation and curettages (D&Cs), three laparoscopies, and one hysterectomy. Sixty-one percent of admissions for adolescent menorrhagia were in adolescents with significant medical problems. The patients with menorrhagia who required admission had severe anemia and were transfused in 63% of cases. The predominant causes for these admissions included anovulation in 46%, hematologic disease in 33%, chemotherapy in 11%, and infection in 11%. Hormonal regulation or suppression of menses should be considered in adolescents with significant medical disease.

    The primary clinical manifestations of polycystic ovary syndrome (PCOS) are hirsutism and irregular menstrual bleeding due to ovarian androgen excess and chronic anovulation. Historically, these features emerge late in puberty or shortly thereafter. The presence of insulin resistance or obesity, both commonly associated with this disorder, seems to further amplify the severity of the presentation. Perhaps, the most important finding is that of progressive hirsutism. Irregular menstrual bleeding is less reliable unless the duration of menstrual irregularity is persistent. However, mild hair growth and chronic anovulation are also regarded as normal components of the late stages of puberty and early adolescence and may persist for several years. It is for this reason that the diagnosis is often not made until later in life when endocrine and metabolic dysfunctions have been firmly established. The evolution of PCOS during early adolescence is not well-understood, but seems to involve abnormal activation of the hypothalamic-pituitary-ovarian-adrenal axis accompanied by specific morphologic changes of the ovary. Efforts to minimize the clinical features of PCOS in young adolescent girls depend on early diagnosis and timely suppression of excess ovarian androgen production.

    Up to 14 percent of women experience irregular or excessively heavy menstrual bleeding. This abnormal uterine bleeding generally can be divided into anovulatory and ovulatory patterns. Chronic anovulation can lead to irregular bleeding, prolonged unopposed estrogen stimulation of the endometrium, and increased risk of endometrial cancer. Causes include polycystic ovary syndrome, uncontrolled diabetes mellitus, thyroid dysfunction, hyperprolactinemia, and use of antipsychotics or antiepileptics. Women 35 years or older with recurrent anovulation, women younger than 35 years with risk factors for endometrial cancer, and women with excessive bleeding unresponsive to medical therapy should undergo endometrial biopsy. Treatment with combination oral contraceptives or progestins may regulate menstrual cycles. Histologic findings of hyperplasia without atypia may be treated with cyclic or continuous progestin. Women who have hyperplasia with atypia or adenocarcinoma should be referred to a gynecologist or gynecologic oncologist, respectively. Ovulatory abnormal uterine bleeding, or menorrhagia, may be caused by thyroid dysfunction, coagulation defects (most commonly von Willebrand disease), endometrial polyps, and submucosal fibroids. Transvaginal ultrasonography or saline infusion sonohysterography may be used to evaluate menorrhagia. The levonorgestrel-releasing intrauterine system is an effective treatment for menorrhagia. Oral progesterone for 21 days per month and nonsteroidal anti-inflammatory drugs are also effective. Tranexamic acid is approved by the U.S. Food and Drug Administration for the treatment of ovulatory bleeding, but is expensive. When clear structural causes are identified or medical management is ineffective, polypectomy, fibroidectomy, uterine artery embolization, and endometrial ablation may be considered. Hysterectomy is the most definitive treatment.

    One hundred and twenty infertile couples (30 each among unexplained infertility, anovulation, tubal factor, and male factor groups) and 30 fertile couples as controls were evaluated for psychological assessment by different psychological test instruments. Initial evaluation was done at recruitment, followed by reassessment at 3, 6, 9 and 12 months during the infertility work-up, and at the end when the specific diagnosis and the management and prognosis were disclosed. Psychological components were found to play a significant role in infertility of unknown etiology, especially in the male partner. They affected the personality and social behavior of the male partner and caused anxiety, but led to depression in the female partner. In cases of organically caused infertility, partners were worried about the other's reaction. Anxiety was significantly greater in the partner with the fertility problem than in the other partner. Life events were significant in the partner in whom the fertility problem was detected. Periodic psychological assessment was not affected by infertility work-up on the male partner in any of the groups, whereas anovulation and tubal factor infertility showed a significant psychological effect on the female partner at the end of work-up. Depression and anxiety in the female partner were evident soon after the investigation started.

    Full Text Available Ugochi C Okoroafor, Emily S JungheimDepartment of Obstetrics and Gynecology, Washington University, St Louis, MO, USAAbstract: Polycystic ovary syndrome (PCOS is a heterogeneous condition characterized by anovulation, hyperandrogenism, and polycystic ovaries. Because of the heterogeneous nature of PCOS, women affected by the condition often require a customized approach for ovulation induction when trying to conceive. Treating symptoms of PCOS in overweight and obese women should always incorporate lifestyle changes with the goal of weight-loss, as many women with PCOS will ovulate after losing 5%–10% of their body weight. On the other hand, other factors must be considered including the woman’s age, age-related decline in fertility, and previous treatments she may have already tried. Fortunately, multiple options for ovulation induction exist for women with PCOS. This paper reviews specific ovulation induction options available for women with PCOS, the benefits and efficacy of these options, and the related side effects and risks women can anticipate with the various options that may affect treatment adherence. The paper also reviews the recommended evidence-based strategies for treating PCOS-related infertility that allow for incorporation of the patient’s preference. Finally, it briefly reviews emerging data and ongoing studies regarding newer agents that have shown great promise as first-line agents for the treatment of infertility in women with PCOS.Keywords: polycystic ovary syndrome, anovulation, clomiphene citrate, letrozole, metformin, obesity

    Evidence is growing that the equilibrium between reactive oxygen species and antioxidants plays a vital role in women's reproductive health. The objective of this study was to evaluate variations in serum antioxidant concentrations across the menstrual cycle and associations between antioxidants and reproductive hormones and anovulation among healthy women. The BioCycle Study, a prospective cohort, followed 259 women aged 18-44 y for up to 2 menstrual cycles. Serum fat-soluble vitamin and micronutrient (α-tocopherol, γ-tocopherol, retinol, lutein, lycopene, and β-carotene), ascorbic acid, and reproductive hormone concentrations were measured 5-8 times/cycle. We used weighted linear mixed models to assess associations between antioxidants and hormone concentrations, after adjustment for age, race, body mass index, parity, sleep, pain medication use, total energy intake, concurrent hormones, serum cholesterol, F2-isoprostanes, and other antioxidants. Generalized linear models were used to identify associations with anovulation. Serum antioxidant concentrations varied across the menstrual cycle. Retinol and α-tocopherol were associated with higher estradiol [RR: 1.00 pg/mL (95% CI: 0.67, 1.34 pg/mL); RR: 0.02 pg/mL (95% CI: 0.003, 0.03 pg/mL), respectively] and testosterone [RR: 0.61 ng/dL (95% CI: 0.44, 0.78 ng/dL); RR: 0.01 ng/dL (95% CI: 0.001, 0.01 ng/dL), respectively]. Ascorbic acid was associated with higher progesterone (RR: 0.15 ng/mL; 95% CI: 0.05, 0.25 ng/mL) and with lower follicle-stimulating hormone (RR: -0.06 mIU/mL; 95% CI: -0.09, -0.03 mIU/mL). The ratio of α- to γ-tocopherol was associated with an increased risk of anovulation (RR: 1.03; 95% CI: 1.01, 1.06). These findings shed new light on the intricate associations between serum antioxidants and endogenous hormones in healthy premenopausal women and support the hypothesis that concentrations of serum vitamins affect steroidogenesis even after adjustment for oxidative stress. © 2016 American

    Does use of commonly used over-the-counter (OTC) pain medication affect reproductive hormones and ovulatory function in premenopausal women? Few associations were found between analgesic medication use and reproductive hormones, but use during the follicular phase was associated with decreased odds of sporadic anovulation after adjusting for potential confounders. Analgesic medications are the most commonly used OTC drugs among women, but their potential effects on reproductive function are unclear. The BioCycle Study was a prospective, observational cohort study (2005-2007) which followed 259 women for one (n = 9) or two (n = 250) menstrual cycles. Two hundred and fifty-nine healthy, premenopausal women not using hormonal contraception and living in western New York state. Study visits took place at the University at Buffalo. During study participation, 68% (n = 175) of women indicated OTC analgesic use. Among users, 45% used ibuprofen, 33% acetaminophen, 10% aspirin and 10% naproxen. Analgesic use during the follicular phase was associated with decreased odds of sporadic anovulation after adjusting for age, race, body mass index, perceived stress level and alcohol consumption (OR 0.36 [0.17, 0.75]). Results remained unchanged after controlling for potential confounding by indication by adjusting for 'healthy' cycle indicators such as amount of blood loss and menstrual pain during the preceding menstruation. Moreover, luteal progesterone was higher (% difference = 14.0, -1.6-32.1, P = 0.08 adjusted) in cycles with follicular phase analgesic use, but no associations were observed with estradiol, LH or FSH. Self-report daily diaries are not validated measures of medication usage, which could lead to some classification error of medication use. We were also limited in our evaluation of aspirin and naproxen which were used by few women.

    The levonorgestrel intrauterine system (LNG-IUS) is an underused contraceptive method in adolescent populations. In addition to being a highly effective, reversible, long-acting contraception, the LNG-IUS has many noncontraceptive health benefits including reduced menstrual bleeding, decreased dysmenorrhea and pelvic pain related to endometriosis, and menstruation suppression in teens with physical or developmental disabilities. The LNG-IUS can also provide endometrial protection in teens with chronic anovulation, and may be used to treat endometrial hyperplasia and cancer. This review examines the evidence supporting the use of the LNG-IUS in adolescents for these noncontraceptive benefits. Copyright © 2013 Society for Adolescent Health and Medicine.

    The effect of season on ovulation has been monitored in two local breeds of Egyptian ewes - the Barki (desert type), and the Rahmani (fat tailed Nile valley breed), by sequentially measuring cyclic changes in plasma progesterone concentration throughout a period of one year in the absence of any possible ram effect. The modal length of the ovulatory cycle was 17-18 days for both breeds, with the progesterone concentration peaking around day 11. No effect of season on progesterone concentration was apparent for the Barki breed but in the Rahmani, progesterone values were lower (P < 0.05) during the summer than during the autumn months. While the Barki have a restricted breeding season from June to November, the Rahmani have only a short period of anovulation within April. Thirty-three per cent of the Rahmani breed were identified as having cycled throughout the year. (author). 9 refs, 4 figs

    Polycystic ovary syndrome (PCOS) is a widespread reproductive disorder that encompasses many associated health conditions and has an impact on various metabolic processes. PCOS is depicted by hyperandrogenism, polycystic ovaries, and anovulation. It increases the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. The etiology of the disease remains unclear, and the subjective phenotype makes a united diagnosis difficult among physicians. It seems to be a familial genetic syndrome caused by a combination of environmental and genetic factors. It can be linked with metabolic disorders in first-degree family members. PCOS is the cause of up to 30% of infertility in couples seeking treatment. Currently, there is no cure for PCOS. Despite the growing incidence of this syndrome, limited research has been done that encompasses the entirety of PCOS spectrum. In this review, the current status and possible future perspective will be discussed. PMID:24389146

    Estradiol valerate (EV)-induced polycystic ovaries (PCOs) in rats cause the anovulation and cystic ovarian morphology. We investigated whether treatment with HemoHIM influences the ovarian morphology and the expression of nerve growth factor (NGF) in an EV-induced PCO rat model. PCO was induced by a single intramuscular injection of EV (4 mg, dissolved in sesame oil) in adult cycling rats. HemoHIM was either administered orally (100 mg/kg of body weight/day) for 35 consecutive days or injected intraperitoneally (50 mg/kg of body weight) every other day after EV injection. Ovarian morphology was almost normalized, and NGF was normalized in the PCO + HemoHIM group. HemoHIM lowered the high numbers of antral follicles and increased the number of corpora lutea in PCOs. The results are consistent with a beneficial effect of HemoHIM in the prevention and treatment of PCO syndrome.

    Full Text Available The diagnosis of the polycystic ovary syndrome continues to be made based on the 2003 Rotterdam criteria which include oligo- or anovulation, hyperandrogenemia and/ or clinical signs of androgen excess, and polycystic ovaries on ultrasound. Nonetheless, the diagnosis is not always clear. In cases where one is unsure whether a woman ovulates, a progesterone level in the mid-luteal phase of the cycle can confirm ovulation. Clinical signs of hyperandrogenemia are strongly influenced by ethnicity, which should be considered during the assessment, although no ethnicity- related norms have been published. Recent studies have shown that AMH in combination with LH can aid in differentiating sonographically observed PCO morphology (a common entity in younger women from true PCOS. For women desiring pregnancy, the first therapeutic step is weight reduction as part of a lifestyle modification. Ovulation induction in these anovulatory women can be accomplished with clomiphene or low-dose gonadotropins, and may be combined with metformin. Clomiphene continues to be the first-line treatment because of its ease of administration, low costs and success rates. Low-dose gonadotropins may have an even higher success rate of ovulation and pregnancy, especially in clomipheneresistant women, but are much more expensive. Metabolic co-morbidities are very common in women with PCOS and should be diagnosed and treated in order to prevent or reduce future consequences. International recommendations include screening women with PCOS for dia betes with fasting glucose and oral glucose tolerance test, especially those with adiposity, anovulation and positive family history. Fasting insulin or HOMA Index can be used to assess for IR. Targeted thera pies for the metabolic aspects of PCOS include diet and exercise as part of lifestyle modification, treatment of hypertension and hypercholesterolemia with appropriate medications, and the use of insulin sensitizers for insulin

    Full Text Available We present the case of a 27-year-old lady who was seen in the infertility clinic with a history of secondary infertility of a one-year duration. She had a hysteroscopy and Mirena insertion for heavy periods. Coil strings were not found by the GP during first coil check six weeks after insertion. A pelvic ultrasound scan did not show any coil, and it was not investigated further with a possible diagnosis of coil expulsion made. One year following that, she was seen in the infertility clinic. Initial investigations revealed anovulation, and HSG located the coil to be extrauterine. Mirena was removed laparoscopically, and a month following the removal she conceived. She is currently pregnant. This case highlights the effect of extrauterine mirena coils on fertility by possibly causing higher plasma levels of levonorgesterol and resulting suppression of ovulation. Laparoscopic removal of mirena coil can help in restoration of fertility.

  6. Obesity and fertility.

    2015-10-01

    The prevalence of overweight and obesity in women of reproductive age has increased over the past 30 years. Infertility affects 1 in 7 couples, and female obesity is associated with anovulation. The mechanisms by which excessive fat delays time to pregnancy (TTP) appear rooted in ovulatory problems and direct effects on oocytes, causing poorer embryo development, as well as in effects on the endometrium. Weight loss in women has been shown to improve conception, but not necessarily live birth rates following fertility treatment, and further research in this area is needed. The obesity epidemic has been accompanied by a potential rise in male infertility, which has been attributed to hormonal disturbances and compromised semen parameters.

    2008-03-01

    Obesity and overweight are common conditions that have consequences not only on general health but also to a great extent on reproductive health. There is a high prevalence of obese women in the infertile population and numerous studies have highlighted the link between obesity and infertility. Obesity contributes to anovulation and menstrual irregularities, reduced conception rate and a reduced response to fertility treatment. It also increases miscarriage and contributes to maternal and perinatal complication. Reduction of obesity, particularly abdominal obesity, is associated with improvements in reproductive functions; hence, treatment of obesity itself should be the initial aim in obese infertile women before embarking on ovulation-induction drugs or assisted reproductive techniques. While various strategies for weight reduction, including diet, exercise, pharmacological and surgical intervention exist, lifestyle modification continues to be of paramount importance.

    2014-01-01

    Obesity can lead to anovulation and subfertility. Around the world fertility treatment is withheld from women above a certain BMI, ranging from 25 to 40 kg/m2. The proponents of this policy use three different arguments to justify their restrictions: risks to the woman, health and wellbeing of the future child, and importance for society. In this article we critically appraise these arguments. In conclusion, we think obese women should be informed about the consequences of their weight on fertility and pregnancy complications and encouraged to lose weight. If, however, a woman is unable to lose weight despite effort, we feel there is no argument to withhold treatment from her. This would be unjustified with respect to the treatment of other women with a high risk of complications.

    Both obesity and overweight are increasing worldwide and have detrimental influences on several human body functions including the reproductive health. In particular, obese women undergo perturbations of the 'hypothalamic pituitary ovarian axis', and frequently suffer of menstrual dysfunction leading to anovulation and infertility. Besides the hormone disorders and subfertility that are common in the polycystic ovary syndrome (PCOS), in obesity the adipocytes act as endocrine organ. The adipose tissue indeed, releases a number of bioactive molecules, namely adipokines, that variably interact with multiple molecular pathways of insulin resistance, inflammation, hypertension, cardiovascular risk, coagulation, and oocyte differentiation and maturation. Moreover, endometrial implantation and other reproductive functions are affected in obese women with complications including delayed conceptions, increased miscarriage rate, reduced outcomes in assisted conception treatments.On the contrary, weight loss programs through lifestyle modification in obese women, have been proven to restore menstrual cyclicity and ovulation and improve the likelihood of conception.

    PCOS is one of the most common endocrine disorders affecting women and it is characterized by a combination of hyper-androgenism, chronic anovulation, and insulin resistance. While a significant progress has recently been made in the diagnosis for PCOS, the optimal infertility treatment remains to be determined. Two inositol isomers, myo-inositol (MI) and D-chiro-inositol (DCI) have been proven to be effective in PCOS treatment, by improving insulin resistance, serum androgen levels and many features of the metabolic syndrome. However, DCI alone, mostly when it is administered at high dosage, negatively affects oocyte quality, whereas the association MI/DCI, in a combination reproducing the plasma physiological ratio (40:1), represents a promising alternative in achieving better clinical results, by counteracting PCOS at both systemic and ovary level. © 2014, The American College of Clinical Pharmacology.

    Full Text Available The aim of study was to evaluate endocrine changes in PCOS women during metformin treatment. One hundred women with PCOS, aged 20-40 years were included. A complete hormonal and metabolic pattern was recorded for each subject every 6 months. Metformin treatment after 6 and 12 months significantly reduced weight, BMI, waist circumference, insulin and HOMA-IR (p=0.000 with high differences of variances within repeated measurements. There was significant reduction of PRL, testosterone and estradiol (p=0.000 with small differences within repeated measurements. Metformin did not have effect on TSH. However, results showed important reduction of CRP, LH, LH/FSH, androstendione, DHEA-S and progesterone (p=0.000 with moderate differences within measures. Metformin restored menstrual cyclicity in most participants. At baseline in study group was 69% women with oligomenorrhoea, amenorrhoea or polymenorrhoea. After 12 months of treatment, only 20% PCOS women had irregular menstrual cycle (p=0.000. Hirsutism was also reduced. Intriguingly, during first 6 months of treatment in PCOS women 9 pregnancies occurred (p=0.000, while during last 6 months treatment were 2 pregnancies (p=0.317, in total 11(13%. Multiple regression model revealed that the presence of anovulation in PCOS women was strongly associated with BMI, waist, FSH and age. Insulin resistance was significantly predicted by BMI, cholesterol, progesterone and presence of hirsutism. The metformin therapy significantly improved insulin resistance, imbalance of endocrine hormones, hirsutism and menstrual cyclicity in women with PCOS. The most important predictors for duration of metformin treatment in PCOS women were testosterone, progesterone, FSH, CRP and presence of anovulation.

    This observational study compares the ratio of serum anti-Mullerian hormone (AMH) to the total antral follicle count (AFC) (as a marker of AMH production per follicle) in the various phenotypes of women with polycystic ovary syndrome (PCOS) and isolated polycystic ovarian morphology (PCOM). Two hundred and sixty-two women were recruited. Women with PCOS were divided into four phenotypes based on the diagnostic inclusion criteria of oligo-anovulation (OA), hyperandrogenism (HA) and polycystic ovarian morphology (PCOM). These included Group A (OA + HA + PCOM), Group B (OA + HA), Group C (HA + PCOM) and Group D (OA + PCOM). A ratio of serum AMH to total AFC was calculated and expressed as the AMH/AFC ratio which was compared in the phenotypes of PCOS and isolated PCOM. The median AMH/AFC ratios in PCOS-A, PCOS-D, PCOS-C and PCOM were 1.5, 1.6, 1.2 and 1.1, respectively. There were significant differences in the groups compared [F(3, 238) = 6.14, p = 0.000)]. The ratios were significantly higher in the oligo-anovulatory phenotypes PCOS-A and PCOS-D than the PCOM (p = 0.004 and 0.002, respectively). There was no significant difference in the ratio between ovulatory phenotype PCOS-C and PCOM (p = 0.59). The role of androgens and LH in per-follicle AMH production remains limited. The findings support the hypothesis of a key role for AMH in the mechanism of anovulation in PCOS.

    Does lifestyle intervention aiming at weight loss influence endometrial insulin signaling in overweight/obese women with polycystic ovary syndrome (PCOS)? Lifestyle intervention up-regulates, both at the mRNA and protein levels, components of insulin signaling in the endometrium of overweight/obese PCOS women, in relation to an improved menstrual pattern. PCOS is a multifactorial endocrine disorder diagnosed by two of the following three criteria: chronic anovulation, hyperandrogenism and polycystic ovaries. Many women with PCOS also have insulin resistance and obesity. The syndrome is furthermore associated with endometrial cancer and possible alterations in endometrial function and receptivity. This study assessed the effects of a combined diet and exercise lifestyle intervention for 3 months. A group of 20 overweight/obese PCOS women with anovulation, hyperandrogenism and polycystic ovaries were subjected to a combined diet and exercise program for 3 months. Ten body mass index (BMI)-matched regularly menstruating overweight/obese controls, nine normal-weight PCOS women and ten normal-weight controls were also included in the study. In an academic clinical setting, women were examined in mid-follicular phase for endocrine assessment and determination of endometrial levels of mRNA and immunohistochemical staining of insulin signaling molecules (the insulin receptor, insulin receptor substrate-1 (IRS1) and glucose transporter (GLUT) 1 and 4). Women with PCOS exhibited lower levels of IRS1 (P PCOS. Levels of IRS1 (P PCOS following lifestyle intervention improves the glucose homeostasis and thereby restores the functioning of the endometrium in these women.

    Oral contraceptive use decreases the risk of ovarian cancer, but no previous studies have assessed the impact of cumulative intake of estrogen and progestin on ovarian cancer risk. We used data from a population-based case–control study conducted in Denmark in 1995–1999 among women aged 35–79 years; 554 women with epithelial ovarian cancer and 1,564 age-matched controls were included in the analyses. Data were analyzed in multiple logistic regression models. The use of combined oral contraceptives only and the mixed use of combined and progestin-only pills decreased the risk of ovarian cancer, while no association was found with exclusive use of progestin-only pills. No major differences in risk were found for users of combined oral contraceptives with high- and low-potency estrogen and progestin. There was no effect of cumulative progestin intake, but decreased risks of ovarian cancer with increasing cumulative intake of estrogen (OR = 0.82; 95 % CI 0.67–0.99, per 100 mg estrogen) and increasing duration of oral contraceptive use (OR = 0.95; 95 % CI 0.92–0.98, per year of use) were found. No effect of cumulative estrogen intake was found, however, after adjustment for duration of oral contraceptive use. The protective effect of oral contraceptives against ovarian cancer may be sufficiently explained by duration of anovulation. This suggests that if the estrogen and progestin doses are sufficient to cause anovulation, a higher intake of estrogen or progestin confers no extra protection against ovarian cancer.

    Full Text Available The current study was conducted to investigate the relationship between melatonin and chronic anovulation. Adult (3-4 months old female Wistar rats were submitted to pinealectomy: group I: pinealectomized ovariectomized melatonin-treated (N = 10; group II: pinealectomized ovariectomized placebo-treated (N = 12; group III: pinealectomized light-treated placebo-treated(N = 10 or maintained under continuous light; group IV: maintained under continuous light, ovariectomized melatonin-treated (N = 22; group V: maintained under continuous light, ovariectomized placebo-treated (N = 10; group VI: maintained under continuous light placebo-treated (N = 10. In order to assess ovarian modifications, unilateral ovariectomy was performed during the fourth month in groups I, II, IV, V and the other ovary was removed after 8 months. Ovariectomy was performed in groups III and VI only after eight months. Melatonin (200 µg/100 g body weight dissolved in 0.02 ml absolute ethanol was injected intramuscularly daily during the last 4 months into groups I and IV. The other groups were treated with placebo (NaCl. The ovarian cysts were analyzed and their area, perimeter and maximum diameter, as well as the thickness of the ovarian capsule were measured. Daily colpocytological smears were performed throughout the study. Persistent estrous condition and ovarian cysts were observed in all groups. In pinealectomized rats the ovarian and vaginal alterations disappeared at the end of the study and in rats maintained under continuous light the vaginal and ovarian polycystic aspect was reversed only in those treated with melatonin. We conclude that melatonin may act on the ovarian response reverting chronic anovulation induced by pinealectomy or continuous light.

  16. The Polycystic Ovary Morphology-Polycystic Ovary Syndrome Spectrum.

    2015-12-01

    Polycystic ovary syndrome (PCOS) is the most common cause of chronic hyperandrogenic anovulation. Two-thirds of PCOS patients have functionally typical PCOS, with typical functional ovarian hyperandrogenism manifest as 17-hydroxyprogesterone hyper-responsiveness to gonadotropin stimulation. Most, but not all, of the remainder have atypical functional ovarian hyperandrogenism. Many asymptomatic volunteers with polycystic ovary morphology (PCOM) have similar abnormalities. The objective of this paper is to review the relationship of biochemical ovarian function to the clinical spectrum observed in PCOS and in normal volunteers with PCOM. Adolescents and adults with PCOS are similar clinically and biochemically. Ninety-five percent of functionally typical PCOS have classic PCOS, ie, hyperandrogenic anovulation with PCOM. In addition to having more severe hyperandrogenism and a greater prevalence of PCOM than other PCOS, they have a significantly greater prevalence of glucose intolerance although insulin resistance is similarly reduced. Half of normal-variant PCOM have PCOS-related steroidogenic dysfunction, which suggests a PCOS carrier state. There is a spectrum of ovarian androgenic dysfunction that ranges from subclinical hyperandrogenemia in some normal-variant PCOM to severe ovarian hyperandrogenism in most classic PCOS. A minority of mild PCOS cases do not fall on this spectrum of ovarian androgenic dysfunction, but rather seem to have obesity as the basis of their hyperandrogenism, or, less often, isolated adrenal androgenic dysfunction. Half of normal-variant PCOM also do not fall on the PCOS spectrum, and some of these seem to have excessive folliculogenesis as a variant that may confer mild prolongation of the reproductive lifespan. Improved understanding of PCOM in young women is needed. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc. All rights reserved.

    To determine whether the measurement of serum AMH can be used to diagnose PCOS and as a tool to predict the prognosis of PCOS. This is a case-control study. Women of reproductive age (18-35 years) were recruited consecutively at a tertiary academic hospital during the period of March 2009-October 2011 and were divided into case (PCOS patients defined by the Rotterdam criteria) and control groups (non-PCOS patients). Menstrual history, clinical manifestations of hyperandrogenism, ovarian ultrasound assessments, and the levels of AMH, LH, FSH, and estradiol were collected. Seventy-one cases and 71 controls were recruited. AMH serum levels were significantly higher in PCOS patients than in controls. The Area Under the Curve (AUC) of the serum AMH assay in PCOS patients reached a value of 0.870. With a cut-off value of 4.45 ng/ml, the serum AMH level had a sensitivity of 76.1 % and a specificity of 74.6 %. The most common phenotypes of PCOS in this study were anovulation and polycystic ovary (63.4 %). However, the mean level of AMH was highest in the phenotypes of anovulation, polycystic ovaries and hyperandrogenism (11.1 ng/ml). In Indonesian women, AMH can be used as an alternative diagnostic criteria for PCOS patients with a cut-off value of 4.45 ng/ml. AMH value rise when hyperandrogenism is present therefore serum AMH levels also reflect the phenotype of PCOS. However, these findings must be confirmed with larger clinical studies.

    Full Text Available Ahmed Badawy1 Abubaker Elnashar21Department of Obstetrics and Gynecology, Mansoura University, Mansoura, Egypt; 2Department of Obstetrics and Gynecology, Benha University, Benha, EgyptAbstract: Polycystic ovary syndrome (PCOS is the most common endocrine disorder in women. The clinical manifestation of PCOS varies from a mild menstrual disorder to severe disturbance of reproductive and metabolic functions. Management of women with PCOS depends on the symptoms. These could be ovulatory dysfunction-related infertility, menstrual disorders, or androgen-related symptoms. Weight loss improves the endocrine profile and increases the likelihood of ovulation and pregnancy. Normalization of menstrual cycles and ovulation could occur with modest weight loss as little as 5% of the initial weight. The treatment of obesity includes modifications in lifestyle (diet and exercise and medical and surgical treatment. In PCOS, anovulation relates to low follicle-stimulating hormone concentrations and the arrest of antral follicle growth in the final stages of maturation. This can be treated with medications such as clomiphene citrate, tamoxifen, aromatase inhibitors, metformin, glucocorticoids, or gonadotropins or surgically by laparoscopic ovarian drilling. In vitro fertilization will remain the last option to achieve pregnancy when others fail. Chronic anovulation over a long period of time is also associated with an increased risk of endometrial hyperplasia and carcinoma, which should be seriously investigated and treated. There are androgenic symptoms that will vary from patient to patient, such as hirsutism, acne, and/or alopecia. These are troublesome presentations to the patients and require adequate treatment. Alternative medicine has been emerging as one of the commonly practiced medicines for different health problems, including PCOS. This review underlines the contribution to the treatment of different symptoms.Keywords: treatment, polycystic ovary

    Energy-containing beverages are widely consumed among premenopausal women, but their association with reproductive hormones is not well understood. The objective was to assess the association of energy-containing beverages, added sugars, and total fructose intake with reproductive hormones among ovulatory cycles and sporadic anovulation in healthy premenopausal women. Women (n = 259) in the BioCycle Study were followed for up to 2 menstrual cycles; they provided fasting blood specimens during up to 8 visits/cycle and four 24-h dietary recalls/cycle. Women who consumed ≥1 cup (1 cup = 237 mL) sweetened soda/d had 16.3% higher estradiol concentrations compared with women who consumed less sweetened soda (86.5 pg/mL compared with 74.4 pg/mL, P = 0.01) after adjustment for age, BMI, race, dietary factors, and physical activity. Similarly elevated estradiol concentrations were found for ≥1 cup cola/d and noncola soda intake. Neither artificially sweetened soda nor fruit juice intake ≥1 cup/d was significantly associated with reproductive hormones. Added sugar above the average US woman's intake (≥73.2 g/d) or above the 66th percentile in total fructose intake (≥41.5 g/d) was associated with significantly elevated estradiol but not consistently across all models. No associations were found between beverages, added sugars, or total fructose intake and anovulation after multivariate adjustment. Even at moderate consumption amounts, sweetened soda is associated with elevated follicular estradiol concentrations among premenopausal women but does not appear to affect ovulatory function. Further research into the mechanism driving the association between energy-containing beverages and reproductive hormones, and its potential implications for women's health, is warranted.

    Polycystic Ovary Syndrome (PCOS) is recognized as the most common endocrine disorder of reproductive-aged women around the world. This document, produced by the collaboration of the American Association of Clinical Endocrinologists (AACE) and the Androgen Excess and PCOS Society (AES) aims to highlight the most important clinical issues confronting physicians and their patients with PCOS. It is a summary of current best practices in 2015. PCOS has been defined using various criteria, including menstrual irregularity, hyperandrogenism, and polycystic ovary morphology (PCOM). General agreement exists among specialty society guidelines that the diagnosis of PCOS must be based on the presence of at least two of the following three criteria: chronic anovulation, hyperandrogenism (clinical or biological) and polycystic ovaries. There is need for careful clinical assessment of women's history, physical examination, and laboratory evaluation, emphasizing the accuracy and validity of the methodology used for both biochemical measurements and ovarian imaging. Free testosterone (T) levels are more sensitive than the measurement of total T for establishing the existence of androgen excess and should be ideally determined through equilibrium dialysis techniques. Value of measuring levels of androgens other than T in patients with PCOS is relatively low. New ultrasound machines allow diagnosis of PCOM in patients having at least 25 small follicles (2 to 9 mm) in the whole ovary. Ovarian size at 10 mL remains the threshold between normal and increased ovary size. Serum 17-hydroxyprogesterone and anti-Müllerian hormone are useful for determining a diagnosis of PCOS. Correct diagnosis of PCOS impacts on the likelihood of associated metabolic and cardiovascular risks and leads to appropriate intervention, depending upon the woman's age, reproductive status, and her own concerns. The management of women with PCOS should include reproductive function, as well as the care of hirsutism

    2009-05-01

    Full Text Available Abstract Background Female mice and rats injected with estrogen perinatally become anovulatory and develop follicular cysts. The current consensus is that this adverse response to estrogen involves the hypothalamus and occurs because of an estrogen-induced alteration in the GnRH delivery system. Whether or not this is true has yet to be firmly established. The present study examined an alternate possibility in which anovulation and cyst development occurs through an estrogen-induced disruption in the immune system, achieved through the intermediation of the thymus gland. Methods, Results and Conclusion A putative role for the thymus in estrogen-induced anovulation and follicular cyst formation (a model of PCOS was examined in female mice by removing the gland prior to estrogen injection. Whereas all intact, female mice injected with 20 ug estrogen at 5–7 days of age had ovaries with follicular cysts, no cysts were observed in animals in which thymectomy at 3 days of age preceded estrogen injection. In fact, after restoring immune function by thymocyte replacement, the majority of thymectomized, estrogen-injected mice had ovaries with corpora lutea. Thus, when estrogen is unable to act on the thymus, ovulation occurs and follicular cysts do not develop. This implicates the thymus in the cysts' genesis and discounts the role of the hypothalamus. Subsequent research established that the disease is transferable by lymphocyte infusion. Transfer took place between 100-day-old estrogen-injected and 15-day-old naïve mice only when recipients were thymectomized at 3 days of age. Thus, a prerequisite for cyst formation is the absence of regulatory T cells. Their absence in donor mice was judged to be the result of an estrogen-induced increase in the thymus' vascular permeability, causing de facto circumvention of the final stages of regulatory T cell development. The human thymus has a similar vulnerability to steroid action during the fetal stage. We

    2011-05-01

    Full Text Available Abstract Background Metformin, an oral biguanide traditionally used for the treatment of type 2 diabetes, is widely used for the management of polycystic ovary syndrome (PCOS-related anovulation. Because of the significant prevalence of insulin resistance and glucose intolerance in PCOS patients, and their putative role in ovulatory dysfunction, the use of metformin was touted as a means to improve ovulatory function and reproductive outcomes in PCOS patients. To date, there has been inconsistent evidence to demonstrate a favorable effect of metformin on oocyte quality and competence in women with PCOS. Given the heterogeneous nature of this disorder, we hypothesized that metformin may be beneficial in mice with aberrant metabolic characteristics similar to a significant number of PCOS patients. The aim of this study was to gain insight into the in vitro and in vivo effects of metformin on oocyte development and ovulatory function. Methods We utilized metformin treatment in the transgenic ob/ob and db/db mutant murine models which demonstrate metabolic and reproductive characteristics similar to women with PCOS. Results: Metformin did not improve in vitro oocyte maturation nor did it have an appreciable effect on in vitro granulosa cell luteinization (progesterone production in any genotype studied. Although both mutant strains have evidence of hyperandrogenemia, anovulation, and hyperinsulinemia, only db/db mice treated with metformin had a greater number of mature oocytes and total overall oocytes compared to control. There was no observed impact on body mass, or serum glucose and androgens in any genotype. Conclusions Our data provide evidence to suggest that metformin may optimize ovulatory performance in mice with a specific reproductive and metabolic phenotype shared by women with PCOS. The only obvious difference between the mutant murine models is that the db/db mice have elevated leptin levels raising the questions of whether their

    Recent studies have shown significant associations between prepartum energy status and postpartum fertility in dairy cows; therefore, the assessment of energy status by blood metabolites and metabolic hormones and suitable improvement of management during the prepartum period may enhance reproductive performance. Rumen fill score (RFS) is associated with feed intake; however, it is unknown whether RFS is also related to blood parameters. Therefore, this study investigated the relationship between RFS and energy status during the prepartum period, and their associations with conception at first artificial insemination (AI) after parturition. In 42 multiparous Holstein cows, RFS assessment and blood sampling were carried out twice a week during 3 weeks of the peripartum period. Ovarian cycles until AI were evaluated by measuring milk progesterone levels. Before calving, positive correlations were observed between RFS and total cholesterol, and RFS did not change in pregnant cows at first AI after parturition, whereas in non-pregnant cows, RFS decreased gradually as the calving day approached. After calving, non-pregnant cows showed lower energy status compared with pregnant cows, and some non-pregnant cows showed anovulation and cessation of estrous cycle. In conclusion, RFS during the close-up dry period is related to real-time energy status, and is associated with postpartum energy status and conception at first AI in dairy cows. © 2016 Japanese Society of Animal Science. © 2016 Japanese Society of Animal Science.

  5. Impact of anorexia, bulimia and obesity on the gynecologic health of adolescents.

    Dieting behaviors and nutrition can have an enormous impact on the gynecologic health of adolescents. Teenaged patients with anorexia nervosa can have hypothalamic suppression and amenorrhea. In addition, these adolescents are at high risk of osteoporosis and fractures. Unfortunately, data suggest that estrogen replacement, even in combination with nutritional supplementation, does not appear to correct the loss of bone density in these patients. Approximately one half of adolescents with bulimia nervosa also have hypothalamic dysfunction and oligomenorrhea or irregular menses. Generally, these abnormalities do not impact bone density and can be regulated with interval dosing of progesterone or regular use of oral contraceptives. In contrast, the obese adolescent with menstrual irregularity frequently has anovulation and hyperandrogenism, commonly referred to as polycystic ovary syndrome. Insulin resistance is thought to play a role in the pathophysiology of this condition. While current management usually involves oral contraceptives, future treatment may include insulin-lowering medications, such as metformin, to improve symptoms. Because all of these patients are potentially sexually active, discussion about contraception is important.

    Full Text Available The impact of obesity on the outcome of assisted reproduction treatments is debatable. Several studies show that obese women have worse outcomes after undergoing fertility treatment. The researches show a worse response to ovulation induction. In the ovarian stimulation stage these women produce fewer follicles. Fertilization rates are poorer and the embryo quality is lower in young women suffering from obesity. According to some studies, pregnancy rates are lower in obese women and there is an increased risk of early pregnancy loss. Weight loss increases the chance of spontaneous ovulation and conception in women that suffer from overweight and obesity.The aim of this study is to describe the different influencing factors related to body mass index in pregnancy rate achieved by artificial insemination in our population.The results of this study show significant results in patients with higher body mass index was positively associated with duration of infertility, lower levels of luteinizing hormone and intrauterine artificial insemination indication increased .It appears more frequently, but without significant result, anovulation and unexplained cause of infertility among obese women, longer cycles, fewer antral follicles and get fewer mature follicles. The average of pregnancy rates was 12.6% but it did not differ significantly among the body mass index categories.

    To determine the prevalence of polycystic ovary syndrome (PCOS) according to the three major diagnostic criteria previously described in an unselected group of women from Spain and to identify the most common phenotypes of the disease. An observational, transversal prevalence study was carried out between July 1 2014 and October 31 2014. All participants received a questionnaire and underwent a physical and trans-vaginal ultrasound examination. Blood samples were also collected for analysis of metabolic markers and hormones. PCOS was diagnosed according to three major criteria: NIH, Rotterdam and AE-PCOS criteria. Following diagnosis women with PCOS were assigned to one of four phenotypes. A total of 242 women were involved in the study. The prevalence for each major criteria was as follows: National Institute of Health (NIH) criteria had a prevalence of 1 4.88%, Rotterdam criteria had a prevalence of 29.34% and Androgen Excess and PCOS Society criteria presented a prevalence of 17.36%. The prevalence for each phenotype was: A, 40.85%; B, 25.35%; C, 8.45%; and D, 25.35%. PCOS women had more prevalence of hirsutism (36.61 %), infertility (25.35%), obesity (21.1 2%) and metabolic syndrome (11 .26%) than controls (7.01%, 6.43%, 5.84% and 2.33% respectively). There is a rise in the prevalence of PCOS in Caucasian population with the classic phenotype (oligo-anovulation, hyperandrogenism, polycystic ovaries) being the most common presentation of the syndrome.

    When pregnancy occurs as a result of assisted reproductive technologies (ART), there are more chances of developing complications and adverse outcomes for the mother and fetus compared to spontaneous pregnancies. Taking into account the noted features, the purpose of our study was to determine the nature of the complications of induced pregnancy and their frequency, depending on the causes of infertility. Under our supervision were 86 women with induced single-pregnancy. Two clinical groups were formed depending on the causes of infertility: group I was represented by 53 observations, in which infertility of endocrine genesis took place; Group II included 33 women with tubal peritoneal infertility. Pregnancy, resulting from ART, should be attributed to the group at high risk of complications of pregnancy. Among the causes of female infertility, the tubal peritoneal factor is the least dangerous in terms of the complicated course of the gestational process, and the endocrine factors that can cause a two-fold increase in the frequency of the threat of abortion and pre-eclampsia are more dangerous. In turn, the cause of endocrine infertility are various factors that need to be determined when predicting the course of induced pregnancy. A special feature of maintaining this category of pregnant women is the constant observation and correction of dyshormonal disorders, which not only cause anovulation, but can also negatively affect the course of pregnancy.

    Polycystic ovarian syndrome (PCOS) induces anovulation in women of reproductive age, and is one of the pathological factors involved in the failure of in vitro fertilization (IVF). Indeed, PCOS women are characterized by poor quality oocytes. Therefore, a treatment for enhancing oocyte quality becomes crucial for these patients. Myo-Inositol and melatonin proved to be efficient predictors for positive IVF outcomes, correlating with high oocyte quality. We tested the synergistic effect of myo-inositol and melatonin in IVF protocols with PCOS patients in a randomized, controlled, double-blind trial. Five-hundred twenty-six PCOS women were divided into three groups: Controls (only folic acid: 400 mcg), Group A (Inofolic® plus, a daily dose of myo-inositol: 4000 mg, folic acid: 400 mcg, and melatonin: 3 mg), and Group B (Inofolic®, a daily dose of myo-inositol: 4000 mg, and folic acid: 400 mcg). The main outcome measures were oocyte and embryo quality, clinical pregnancy and implantation rates. The treatment lasted from the first day of the cycle until 14 days after embryo transfer. Myo-inositol and melatonin have shown to enhance, synergistically, oocyte and embryo quality. In consideration of the beneficial effect observed in our trial and on the bases of previous studies, we decided to integrate routinely MI and M supplementation in the IVF protocols. The same treatment should be taken carefully in consideration in all procedures of this kind.

    Menopause in women occurs at mid-life. Chimpanzees, in contrast, continue to display cycles of menstrual bleeding and genital swelling, suggestive of ovulation, until near their maximum life span of about 60 years. Because ovulation was not confirmed hormonally, however, the age at which chimpanzees experience menopause has remained uncertain. In the present study, we provide hormonal data from urine samples collected from 30 female chimpanzees, of which 9 were old (>30 years), including 2 above the age of 50 years. Eight old chimpanzees showed clear endocrine evidence of ovulation, as well as cycles of genital swelling that correlated closely with measured endocrine changes. Endocrine evidence thus confirms prior observations (cyclic anogenital swelling) that menopause is a late-life event in the chimpanzee. We also unexpectedly discovered an idiopathic anovulation in some young and middle-aged chimpanzees; this merits further study. Because our results on old chimpanzees validate the use of anogenital swelling as a surrogate index of ovulation, we were able to combine data on swelling and urinary hormones to provide the first estimates of age-specific rates of menopause in chimpanzees. We conclude that menopause occurs near 50 years of age in chimpanzees as it does in women. Our finding identifies a basic difference between the human and chimpanzee aging processes: female chimpanzees can remain reproductively viable for a greater proportion of their life span than women. Thus, while menopause marks the end of the chimpanzee's life span, women may thrive for decades more.

    Polycystic ovarian syndrome (PCOS) is known to be one of the most prevalent endocrine disorders affecting reproductive age women. One of the endocrine disorder is hyperinsulinemia, which corresponds with the severity of PCOS. However, the pathogenesis of PCOS is not fully understood, but one theory of anti-mullerian hormone (AMH) has been proposed as one of the factor related to the degree of severity of PCOS. However, there are no clear correlation between levels of AMH with the incidence of insulin resistance in PCOS patients especially in Indonesia. This is a cross-sectional study involving reproductive age women aged 18-35 years. Subjects were recruited consecutively at Dr. Cipto Mangunkusumo General Hospital between 2011 until 2014. PCOS women diagnosed using 2003 Rotterdam criteria were categorized into four different PCOS phenotypes. Subsequently, serum level of AMH and HOMA-IR was measured and evaluated with correlation tests performed using SPSS 11.0 RESULTS: A total of 125 PCOS patients were included in a study conducted within a 3-year period. Phenotype 1 (anovulation, hyperandrogenism, and polycystic ovaries) shows the highest levels of AMH and HOMA-IR, which decreases in accordance to severity level (p HOMA-IR persisted even after adjusting for BMI in multivariate analysis. There was a positive correlation between serum AMH and HOMA IR levels. Serum AMH and HOMA IR levels were significantly different across the four PCOS phenotypes; with the highest values were present with phenotype 1.

    Fifty-two women, aged from 25 to 41 years, with infertility due to chronic anovulation were admitted to the study together with 36 age-matched controls with proven ovulatory cycles. Paired plasma (3 ml) and whole unstimulated saliva (10 ml) samples were collected over a 30 day period, starting from the first day of a menstrual bleeding, in patients, and throughout the menstrual cycle, in controls. Salivary progesterone levels, measured in women with infertility, ranged from undetectable values to 16 pmol/l during the first, and from 36 to 98 pmol/l during the second half of the monitoring period. In eugonadal women the steroid levels ranged from 34 to 46 pmol/I and from 96 to 780 pmol/l during the follicular and luteal phases, respectively. The saliva/plasma progesterone ratio ranged from 0.58 to 2.71 p. cent and a good correlation between salivary and plasma levels was found at each time of monitoring. Many (86 p. cent) of patients, which were randomly allocated to a low-or high-dose epimestrol administration schedule, appeared to be sensitive to the drug, achieving, after therapy, salivary progesterone levels which were within the range of controls. Since correct assessment of luteal function in basal conditions and during therapy requires multiple steroid measurements, and since saliva can be obtained by non-invasive techniques, salivary assays represent an attractive alternative to plasma ones for monitoring ovarian activity, also during specific treatment

    Full Text Available Individuals under chronic psychological stress can be difficult to identify clinically. There is often no outwardly visible phenotype. Chronic stress of sufficient magnitude not only impacts reproductive function, but also concomitantly elicits a constellation of neuroendocrine changes that may accelerate aging in general and brain aging in particular. Functional hypothalamic amenorrhea, a phenotypically recognizable form of stress, is due to stress-induced suppression of endogenous gonadotropin-releasing hormone secretion. Reversal of functional hypothalamic amenorrhea includes restoration of ovulatory ovarian function and fertility and amelioration of hypercortisolism and hypothyroidism. Taken together, recovery from functional hypothalamic amenorrhea putatively offers neuroprotection and ameliorates stress-induced premature brain aging and possibly syndromic Alzheimer’s disease. Amenorrhea may be viewed as a sentinel indicator of stress. Hypothalamic hypogonadism is less clinically evident in men and the diagnosis is difficult to establish. Whether there are other sex differences in the impact of stress on brain aging remains to be better investigated, but it is likely that both low estradiol from stress-induced anovulation and low testosterone from stress-induced hypogonadism compromise brain health.

    Full Text Available Polycystic ovary syndrome (PCOS is characterized by chronical anovulation and hyperandrogenism which may be present in a different degree of severity. Insulin-resistance and hyperinsulinemia are the main physiopathological basis of this syndrome and the failure of inositol-mediated signaling may concur to them. Myo (MI and D-chiro-inositol (DCI, the most studied inositol isoforms, are classified as insulin sensitizers. In form of glycans, DCI-phosphoglycan and MI-phosphoglycan control key enzymes were involved in glucose and lipid metabolism. In form of phosphoinositides, they play an important role as second messengers in several cellular biological functions. Considering the key role played by insulin-resistance and androgen excess in PCOS patients, the insulin-sensitizing effects of both MI and DCI were tested in order to ameliorate symptoms and signs of this syndrome, including the possibility to restore patients’ fertility. Accumulating evidence suggests that both isoforms of inositol are effective in improving ovarian function and metabolism in patients with PCOS, although MI showed the most marked effect on the metabolic profile, whereas DCI reduced hyperandrogenism better. The purpose of this review is to provide an update on inositol signaling and correlate data on biological functions of these multifaceted molecules, in view of a rational use for the therapy in women with PCOS.

    Gynecological problems are one of the most frequent somatic complications of eating disorders. The purpose of the present study was to assess the role of improper eating habits in the aetiology of menstrual disturbances, anovulation and hormonal related changes. Bulimia nervosa is the focus of attention since amenorrhea is considered a diagnostic criterium in anorexia nervosa. Subjects of the BITE (Bulimia Investigation Test, Edinburgh) test who were infertile were studied (n = 58) In the studied population there were 6 cases of clinical and 8 cases of subclinical bulimia nervosa. Symptoms and severity subscales of the BITE test significantly correlated with body mass index (p = 0.003). All 14 patients suffering from clinical and subclinical bulimia nervosa had pathologically low FSH and LH hormone levels. In those with clinical bulimia nervosa (n = 6) we diagnosed 4 cases of multicystic ovary (MCO) and in the eating disorder not otherwise specified (EDNOS) group (n = 22) there were 2 cases of MCO and 5 cases of polycystic ovary syndrome (PCOS). The results suggest that unsatisfactory nutrition (binges and "crash diet") in bulimia nervosa results in hormonal dysfunction, menstrual disturbances and infertility. The authors question the necessity for immediately estrogen replacement: they consider the reversibility of the hormonal status by early treatment of eating disorders is more appropriate. Excessive use of hormonal contraceptives in therapy has to be questioned.

    Gynecological problems are one of the most frequent somatic complications of eating disorders. The purpose of the present study was to assess the role of improper eating habits causing menstrual disturbances, anovulation and related hormonal changes. Latent bulimia nervosa is in the focus of attention since amenorrhea is considered as a diagnostic criterion of anorexia nervosa. Subjects of the BITE (Bulimia Investigation Test, Edinburgh) test were infertile patients (n = 34) of the gynecological outpatient departments after medical examination, blood-test (LH, FSH, androstenedione, DHEAS, progesterone, testosterone, SHBG, prolactin) and ultrasonic examination (uterus and ovaries). Symptoms and severity subscales of the BITE test and body mass index (BMI) were close correlation (p = 0.003, p = 0.033). In comparison with previous results, EDNOS (Eating Disorders Not Otherwise Specified) prevalence was 48%. Of hormonal changes, low LH and FSH levels (6/6) and hyperandrogenism (5/6) were significant in patients with subclinical eating disorders (n = 6) by infertile women as compared with the "normal" infertile group (n = 18; 7/18, 8/18). The recent results suggests that unsatisfactory nutrition (bulimic binges, "crash diet") is as relevant in hormonal dysfunction, menstrual disturbances and infertility as pathologically low weight in anorexia nervosa. Excessive application of contraceptives in therapy has to be taken into consideration.

    The prolactinomas are the most common functioning pituitary tumors. The hyperprolactinemia is associated with anovulation and infertility. a) describe the relationship between hyperprolactinemia and fertility, b) review the results of the use of dopamine agonists during pregnancy and embryo-fetal development and c) review the therapeutic management in micro and macroprolactinomas during pregnancy. Medical therapy with dopamine agonists is the best treatment for prolactinomas of any size or invasiveness and restores ovulatory cycles in 80-90 % of patients. Cabergoline currently suggested rather than bromocriptine due to their excellent tolerability and long half-life. In general, it is recommended that fetal exposure to all drugs be limited to as short a period as possible. In the absence of menstrual period, the drug should be discontinued and confirm pregnancy. Both, bromocriptine and cabergoline, showed no evidence of obstetric and neonatal complications; however, experience with bromocriptine is higher. The patients with macroprolactinomas should be monitored clinically and evaluate the symptoms related to increased tumor size. If growth in the adenoma is suspected, nuclear magnetic resonance and neuro-ophthalmologic examination should be performed. In microprolactinomas the ophthalmologic examination is no formal indication. There is evidence that breastfeeding no increased risk for tumor growth.

    Polycystic ovary syndrome (PCOS) is a heterogeneous clinical entity that is defined as the association of hyperandrogenism with chronic anovulation in women without specific underlying diseases of the adrenal or pituitary glands. PCOS is also associated with a metabolic disturbance (insulin resistance). The nature of the complex interrelation of obesity, insulin resistance and endocrine abnormalities in PCOS remains unresolved. However, several studies link obesity, body fat distribution and nutritional habitus with the hormonal and metabolic profiles of PCOS. Moreover, intervention studies have suggested that reducing weight and/or hyperinsulinaemia either by diet alone or by a combination of diet and drugs improves hirsutism, fertility and the hormonal and metabolic profiles of PCOS. In fact, the evaluation of nutritional factors in PCOS is helpful for the screening of metabolic abnormalities and the management of women with PCOS. A point of particular interest in the management of PCOS is that the choice of contraception remains difficult in these high cardiovascular risk women. The impact of pills with ethinyl oestradiol on weight, body fat distribution and carbohydrate metabolism in women with PCOS has not been thoroughly evaluated. The lack of prospective studies to evaluate long-term metabolic and cardiovascular tolerance necessitates care and the assessment of other hormonal possibilities.

    Estrogens regulate body weight and reproduction primarily through actions on estrogen receptor-α (ERα). However, ERα-expressing cells mediating these effects are not identified. We demonstrate that brain-specific deletion of ERα in female mice causes abdominal obesity stemming from both hyperphagia and hypometabolism. Hypometabolism and abdominal obesity, but not hyperphagia, are recapitulated in female mice lacking ERα in hypothalamic steroidogenic factor-1 (SF1) neurons. In contrast, deletion of ERα in hypothalamic pro-opiomelanocortin (POMC) neurons leads to hyperphagia, without directly influencing energy expenditure or fat distribution. Further, simultaneous deletion of ERα from both SF1 and POMC neurons causes hypometabolism, hyperphagia, and increased visceral adiposity. Additionally, female mice lacking ERα in SF1 neurons develop anovulation and infertility, while POMC-specific deletion of ERα inhibits negative feedback regulation of estrogens and impairs fertility in females. These results indicate that estrogens act on distinct hypothalamic ERα neurons to regulate different aspects of energy homeostasis and reproduction. Copyright © 2011 Elsevier Inc.

    Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder, which is characterized by hyperandrogenism, insulin resistance and chronic anovulation, and has become a serious threat to the health of adolescents and women of childbearing age.At present,lowering androgen, improving insulin resistance and inducing ovulation are the main methods adopted by doctors to treat the disease, but the adverse reactions of the western medicine and the long-term treatment are hard to be accepted by the patients. PCOS treated by traditional Chinese medicine has achieved a certain effect in recent years.Traditional Chinese medicine is relatively safe and has more effect in many links and targets in improving the symptom of endocrine and metabolic disorder in patients with PCOS. This paper expounds the traditional Chinese medicine pathogenesis of PCOS through clinical and experimental aspects of the literature research:correcting endocrine hormone disorder,the effects of the expression of gene and regulatory factors,improving insulin resistance,correcting lipid metabolic disorder,improving the pregnancy outcome and improving ovarian morphology to summarize the treatment of traditional Chinese medicine in PCOS research results in recent years.

    Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder of women, with complex pathogenesis and heterogeneous manifestations. Professor Jin Yu recently wrote an article entitled "Proposal of Diagnosis and Diagnostic Classification of PCOS in Integrated Traditional Chinese and Western Medicine."From this, the Obstetrics and Gynecology branches of the Chinese Association of Integrative Medicine and the China Association of Chinese Medicine collaborated with the Gynecology branch of the Chinese Association for Research and Advancement of Chinese Medicine to draft a report on the consensus of criteria for the diagnosis and classification of PCOS in integrated traditional Chinese and Western medicine. The diagnosis for PCOS includes all three features: (1) oligo-ovulation or anovulation; (2) clinical and/or laboratory evidence of hyperandrogenism;(3) PCOS is classified into four types: types Ia,Ib, IIa, and IIb. Syndrome differentiation types for PCOS in traditional Chinese medicine are as follows: Kidney deficiency with phlegm blockage syndrome, Kidney Yin deficiency with phlegm blockage and blood stasis syndrome, and Kidney deficiency with Liver Qi stagnation syndrome.

    2015-01-01

    Full Text Available Several studies over the past decade have now consistently indicated that the serum anti-Mullerian hormone (AMH levels are at least 2–3-fold higher in the patients with polycystic ovary syndrome (PCOS, which also corresponds to the increased number of AMH producing preantral and small antral follicles. Moreover, AMH levels have been found to be associated in direct proportion to the follicle numbers per ovary or antral follicular count, assessed by the transvaginal ultrasound (TVS. Furthermore, AMH correlates directly with the rising serum testosterone and luteinizing hormone levels in PCOS. Hence, serum AMH in women with oligo-anovulation and/or hyperandrogenemia could indicate the presence of underlying PCOS, when reliable TVS is not feasible, or not acceptable, either due to the virginal status or psycho-social issue. In addition, the imaging quality of abdominal ultrasound is often impaired by obesity, which typically occurs in PCOS women. Indeed, PCOS occurs most commonly in young females who cannot be subjected to invasive TVS for various reasons; therefore, a desirable alternative to TVS is urgently required to diagnose the most prevalent endocrine abnormality of young women. This review will analyze the currently available evidence regarding the role of AMH in the diagnosis of PCOS.

    Functional hypothalamic amenorrhoea (FHA) is associated with functional inhibition of the hypothalamic-pituitary-ovarian axis. Causes of FHA can be classified into the three groups: 1) stress-related factors, 2) consequences of weight loss and/or underweight, and 3) consequences of physical exercise or practicing sports. Diagnosis of FHA should be based on a history of menstrual disorders. During physical examination, patients with FHA present with secondary and tertiary sex characteristics specific for the pubertal stage preceding development of the condition and with the signs of hypoestrogenism. Laboratory results determine further management of patients with amenorrhea, and thus their correct interpretation is vital for making appropriate therapeutic decisions. Treatment of chronic anovulation, menstrual disorders, and secondary amenorrhea resulting from hypothalamic disorders should be aimed at the elimination of the primary cause, i.e. a decrease in psycho-emotional strain, avoidance of chronic stressors, reduction of physical exercise level, or optimisation of BMI in patients who lose weight. If menses do not resume after a period of six months or primary causative treatment is not possible, neutralisation of hypoestrogenism consequences, especially unfavourable effects on bone metabolism, become the main issue. Previous studies have shown that oestroprogestagen therapy is useful in both the treatment of menstrual disorders and normalisation of bone mineral density. Hormonal preparations should be introduced into therapeutic protocol on an individualised basis.

    2013-01-01

    Full Text Available Polycystic ovary syndrome is a complex hormonal disorder affecting the reproductive and metabolic systems with signs and symptoms related to anovulation, infertility, menstrual irregularity and hirsutism. Skeletal muscle plays a vital role in the peripheral glucose uptake. Since PCOS is associated with defects in the activation and pancreatic dysfunction of β-cell insulin, it is important to understand the molecular mechanisms of insulin resistance in PCOS. Studies of muscle tissue in patients with PCOS reveal defects in insulin signaling. Muscle biopsies performed during euglycemic hyperinsulinemic clamp showed a significant reduction in glucose uptake, and insulin-mediated IRS-2 increased significantly in skeletal muscle. It is recognized that the etiology of insulin resistance in PCOS is likely to be as complicated as in type 2 diabetes and it has an important role in metabolic and reproductive phenotypes of this syndrome. Thus, further evidence regarding the effect of nonpharmacological approaches (e.g., physical exercise in skeletal muscle of women with PCOS is required for a better therapeutic approach in the management of various metabolic and reproductive problems caused by this syndrome.

    This study was conducted to investigate expression of matrix metalloproteinases (MMPs) and ovarian morphological changes in androgenized cyclic female guinea pigs. Adult cyclic female guinea pigs were injected daily for 28 days with medium doses of testosterone propionate (TP; 1 mg/100g), high doses of TP (2 mg/100g), or saline (control). Serum concentrations of testosterone, estradiol (E2), and progesterone (P4) were measured. Histologic sections of ovaries were stained with hematoxylin-eosin and by immunohistochemistry. Expressions of steroidogenic acute regulatory protein, proliferating cell nuclear antigen, and MMP-2 and MMP-9 in the ovary were characterized by immunohistochemistry. After 28 days of TP injection, serum testosterone concentrations were increased dose-dependently. An appropriate dosage of TP could induce permanent anovulation in guinea pigs, making them a potential model for human polycystic ovary syndrome. MMP-2 and MMP-9 are jointly involved in the growth and atresia of ovarian follicles in cyclic guinea pigs. Increased numbers of atretic antral follicles in the ovary might be associated with the observed high expression of MMP-2 in androgenized cyclic guinea pigs. Copyright © 2015 Elsevier Ltd.

    Full Text Available Few studies address alteration of sexual function in women with diabetes and chronic kidney disease (CKD. Quality of life surveys suggest that discussion of sexual function and other reproductive issues are of psychosocial assessment and that education on sexual function in the setting of chronic diseases such as diabetes and CKD is widely needed. Pharmacologic therapy with estrogen/progesterone and androgens along with glycemic control, correction of anemia, ensuring adequate dialysis delivery, and treatment of underlying depression are important. Changes in lifestyle such as smoking cessation, strength training, and aerobic exercises may decrease depression, enhance body image, and have positive impacts on sexuality. Many hormonal abnormalities which occur in women with diabetes and CKD who suffer from chronic anovulation and lack of progesterone secretion may be treated with oral progesterone at the end of each menstrual cycle to restore menstrual cycles. Hypoactive sexual desire disorder (HSDD is the most common sexual problem reported by women with diabetes and CKD. Sexual function can be assessed in women, using the 9-item Female Sexual Function Index, questionnaire, or 19 items. It is important for nephrologists and physicians to incorporate assessment of sexual function into the routine evaluation protocols.

    Detailed characterization of progesterone and ovulation across the menopausal transition provides insight into conception risk and mechanisms of reproductive aging. Participants (n = 108, aged 25-58 y) collected daily urine specimens for 6-month intervals in each of 5 consecutive years. Specimens were assayed for pregnanediol glucuronide (PDG), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estrone glucuronide (E1G). Reproductive stage was determined using cycle length variance. A hierarchical algorithm was used to identify ovulation. Linear mixed-effects models estimated (1) the frequency and day of ovulation by age and stage; (2) differences in FSH, LH, and E1G levels between ovulatory (O) and anovulatory (AO) cycles; and (3) total PDG levels and PDG levels in O cycles by age and stage. The probability of AO cycles increased across the perimenopause (P 60%), but one quarter of cycles longer than 60 days were O. Average day of ovulation was later in the late perimenopause (mean [SD] cycle day, 27 [25] d) compared with the premenopause. FSH and LH levels were higher and E1G levels were lower in AO than O cycles (P < 0.0001 for each). Total PDG decreased in the late perimenopause, but 95th percentile PDG in O cycles declined steadily across the transition. Exposure to the risk of conception in women experiencing cycles long enough to classify them as late perimenopausal is far from negligible. Reproductive stage is more informative than age about PDG levels and the likelihood of anovulation.

    Full Text Available Polycystic ovarian syndrome (PCOS is a low grade inflammatory disease characterized by hyperandrogenemia and chronic anovulation. C-reactive protein (CRP, released by adipocytes, plays a key role in PCOS. Apis mellifera honeybee venom (HBV contains a variety of biologically active components with various pharmaceutical properties. This study was designed to assess the possibility of HBV application as an anti-inflammatory therapeutic agent. To induce PCOS, 1 mg/100 g body weight estradiol valerate (EV was subcutaneously (SC injected into eight-week-old rats. After 60 days, 0.5 mg/kg HBV was administered SC for 14 consecutive days, and the results of PCOS treatment were investigated. Rats were then anesthetized with chloroform, and their ovaries and livers were surgically removed to determine histomorphometrical changes. Testosterone and 17-β-estradiol were detected by chemiluminescence immunoassay. In order to detect serum CRP, ELISA kit was used in three groups of EV-induced PCOS, HBV-treated PCOS and control animals. Thickness of the theca layer, number of cysts and the level of serum CRP significantly decreased in HBV group in comparison with PCOS group. Moreover, corpus luteum, as a sign of ovulation, was observed in HBV-treated ovaries which were absent in PCOS group. Our results suggest that the beneficial effect of HBV may be mediated through its inhibitory effect on serum CRP levels.

    Polycystic ovary syndrome (PCOS) is a complicated reproductive endocrine disease characterized by polycystic ovaries, hyperandrogenism and anovulation. It is one of the main causes of infertility. RU486 is an antagonist of progesterone receptor, and most commonly used as a contraceptive. However, whether RU486 is correlated with PCOS remains unclear. Atrial natriuretic peptide (ANP) is a small peptide with natriuretic and diuretic functions, and its availability to be used in PCOS treatment is unknown. Here, we showed that the serum ANP level was lower in PCOS patients than that in healthy women, and it was also decreased in the serum and ovarian tissues of RU486-induced PCOS rats compared with the control rats. We also found that RU486 inhibited the proliferation and promoted the apoptosis of human KGN ovarian granulosa cells by downregulating progesterone receptor membrane component 1 (PGRMC1). Meantime, ANP promoted the proliferation and inhibited the apoptosis of KGN cells through upregulating ANP receptor A (NPRA). The promotive effects of ANP on ovarian functions were mediated through the formation of an NPRA/PGRMC1/EGFR complex, which further activated MAPK/ERK signaling and transcription factor AP1. Moreover, ANP treatment reversed the PCOS symptoms, and improved the fertility of RU486-induced PCOS rats. Collectively, these findings highlight that RU486 is associated with the pathogenesis of PCOS, and ANP treatment may be a promising therapeutic option for PCOS.

    Background Subclinical hypothyroidism (SCH) is present in 5%-10% of polycystic ovary syndrome (PCOS) patients. To date, its impact on the metabolic and hormonal profile of those women remains controversial. The purpose of our study is to evaluate the impact of SCH on the glycemic, lipid and hormonal profile of PCOS patients. Materials and methods We conducted a prospective case control study of patients that attended the Department of Gynecological Endocrinology of our hospital. Results Overall, 280 women with PCOS were enrolled during a time period of 7 years (2009-2015). Twenty-one patients (7.5%) suffered from SCH. The anthropometric characteristics were comparable among women with PCOS and those with SCH + PCOS. The prevalence of acne, hirsutism and anovulation did not differ. Significant differences were observed in the 2-h oral glucose tolerance test (OGTT) (p = 0.003 for glucose and p = 0.046 for insulin). The QUICKI, Matsuda and homeostatic model assessment-insulin resistance (HOMA-IR) indices where, however, similar. No difference in serum lipids was observed. Slightly elevated levels of follicle stimulating hormone (FSH) and testosterone were noted. The remaining hormonal parameters remained similar among groups. Similarly, the ovarian volume and the endometrial thickness did not differ. Conclusions The impact of SCH on the metabolic and hormonal profile of PCOS patients seems to be negligible. Future studies are needed in the field and their conduct in a multi-institutional basis seems to be required, given the small prevalence of SCH among women with PCOS.

    Polycystic ovary syndrome (PCOS) is the most common, though heterogeneous, endocrine aberration in women of reproductive age, with high prevalence and socioeconomic costs. The syndrome is characterized by polycystic ovaries, chronic anovulation and hyperandrogenism, as well as being associated with infertility, insulin resistance, chronic low-grade inflammation and an increased life time risk of type 2 diabetes. MicroRNAs (miRNAs) are small, non-coding RNAs that are able to regulate gene expression at the post-transcriptional level. Altered miRNA levels have been associated with diabetes, insulin resistance, inflammation and various cancers. Studies have shown that circulating miRNAs are present in whole blood, serum, plasma and the follicular fluid of PCOS patients and that they might serve as potential biomarkers and a new approach for the diagnosis of PCOS. In this review, recent work on miRNAs with respect to PCOS will be summarized. Our understanding of miRNAs, particularly in relation to PCOS, is currently at a very early stage, and additional studies will yield important insight into the molecular mechanisms behind this complex and heterogenic syndrome.

    Polycystic ovary syndrome (PCOS), a complex endocrine disorder, is a leading cause of female infertility. An obvious reason for infertility in PCOS women is anovulation. However, success rate with high quality embryos selected by assisted reproduction techniques in PCOS patients still remain low with a high rate of early clinical pregnancy loss, suggesting a problem in uterine receptivity. Using a dehydroepiandrosterone-induced mouse model of PCOS, some potential causes of decreased fertility in PCOS patients were explored. In our study, ovulation problem also causes sterility in PCOS mice. After blastocysts from normal mice are transferred into uterine lumen of pseudopregnant PCOS mice, the rate of embryo implantation was reduced. In PCOS mouse uteri, the implantation-related genes are also dysregulated. Additionally, artificial decidualization is severely impaired in PCOS mice. The serum estrogen level is significantly higher in PCOS mice than vehicle control. The high level of estrogen and potentially impaired LIF-STAT3 pathway may lead to embryo implantation failure in PCOS mice. Although there are many studies about effects of PCOS on endometrium, both embryo transfer and artificial decidualization are applied to exclude the effects from ovulation and embryos in our study.

  16. Relationship between serum anti-Mullerian hormone and intrafollicular AMH levels in PCOS women.

    Polycystic ovary syndrome is a complex disease characterized by various endocrine disorders that are the potential cause of anovulation and hyperandrogenism. Anti-Müllerian hormone expression is suspected to be overexpressed in PCOS granulosa cells. AMH acts as a regulator of folliculogenesis: it is produced by the granulosa cells of follicles from the stage of the primary follicle to the initial formation of the antrum. Serum and intrafollicular AMH levels are elevated in patients with PCOS due to increased number of small follicles and an increased secretion within each of these small follicles. This excess of AMH is strongly suspected to play a role in the characteristic follicular arrest of PCOS, through a negative action on aromatase expression and on FSH action. Value above 5 ng/ml or 35 pmol/l might be considered as a diagnostic criterion for PCOS. The aim of our study is to demonstrate the presence of higher AMH serum levels and higher AMH intrafollicular fluid level of PCOS patients, undergone to IVF cycles, compared to normovulatory patients. The results clearly indicate that blood and intrafollicular AMH levels are significantly higher in PCOS women comparing to the normovulatory population. Serum AMH level appears to be a good predictive marker for the risk ovarian hyperstimulation syndrome: thus, its evaluation should be recommended before starting a controlled ovarian stimulation for IVF.

    Polycystic ovary syndrome (PCOS) is variously reported to affect between 5% and 26% of reproductive age women in the UK and accounts for up to 75% of women attending fertility clinics due to anovulation. The first-line treatment option for overweight/obese women with PCOS is diet and lifestyle interventions. However, optimal dietary guidelines are missing, with very little research having been done in this area. This paper presents the findings from a qualitative study (using semistructured interviews) of ten obese women who had PCOS and who had used LighterLife Total (LLT), a commercial weight loss program which utilizes a very low-calorie diet in conjunction with behavioral change therapy underpinned by group support. We investigated the women's history of obesity, their experiences of other diets compared with LLT, and the on-going impact that this has had on their lives. Findings show that most women reported greater success using this weight loss program in terms of achieving and maintaining weight loss when compared with other diets. Furthermore, all the women nominated LLT as their model weight loss intervention with only a few modifications.

    Obesity has been linked with a host of metabolic and reproductive disorders including polycystic ovary syndrome (PCOS). While a clear association exists between obesity and PCOS, the exact nature of this relationship remains unexplained. The primary symptoms of PCOS include hyperandrogenism, anovulation, and polycystic ovaries. Most animal models utilize androgen treatments to induce PCOS. However, these models often fail to address the underlying causes of the disease and do not effectively reproduce key metabolic features such as hyperinsulinemia. Here, we present a novel rodent model of diet-induced obesity that recapitulates both the metabolic and reproductive phenotypes of human PCOS. Rats on a high-fat high-sugar (HFHS) diet not only demonstrated signs of metabolic impairment, but they also developed polycystic ovaries and experienced irregular estrous cycling. Though hyperandrogenism was not characteristic of HFHS animals as a group, elevated testosterone levels were predictive of high numbers of ovarian cysts. Alterations in steroidogenesis and folliculogenesis gene expression were also found via RNA sequencing of ovarian tissue. Importantly, the PCOS-like symptoms induced in these rats may share a similar etiology to PCOS in humans. Therefore, this model offers a unique opportunity to study PCOS at its genesis rather than following the development of disease symptoms.

  19. Contraception during perimenopause.

    Perimenopause marks the transition from normal ovulation to anovulation and ultimately to permanent loss of ovarian function. Fecundity, the average monthly probability of conception, declines by half as early as the mid-forties, however women during the perimenopause still need effective contraception. Issues arising at this period such as menstrual cycle abnormalities, vasomotor instability, the need for osteoporosis and cardiovascular disease prevention, as well as the increased risk of gynecological cancer, should be taken into consideration before the initiation of a specific method of contraception. Various contraceptive options may be offered to perimenopausal women, including oral contraceptives, tubal ligation, intrauterine devices, barrier methods, hormonal injectables and implants. Recently, new methods of contraception have been introduced presenting high efficacy rates and minor side-effects, such as the monthly injectable system, the contraceptive vaginal ring and the transdermal contraceptive system. However, these new methods have to be further tested in perimenopausal women, and more definite data are required to confirm their advantages as effective contraceptive alternatives in this specific age group. The use of the various contraceptive methods during perimenopause holds special benefits and risks that should be carefully balanced, after a thorough consultation and according to each woman's contraceptive needs.

    Polycystic ovary syndrome is the most common endocrine disorder among women of reproductive age. Although traditionally viewed as a reproductive disorder, there is increasing appreciation that it is associated with significantly increased risk of cardiometabolic disorders. Women with polycystic ovary syndrome may present to clinicians via a variety of different routes and symptoms. Although the impact on reproduction predominates during the reproductive years, the increased cardiometabolic problems are likely to become more important at later stages of the life course. Women with polycystic ovary syndrome have an approximately 2- to 5-fold increased risk of dysglycaemia or type 2 diabetes, and hence regular screening with oral glucose tolerance test is warranted. Although the diagnostic criteria for polycystic ovary syndrome are still evolving and are undergoing revision, the diagnosis is increasingly focused on the presence of hyperandrogenism, with the significance of polycystic ovarian morphology in the absence of associated hyperandrogenism or anovulation remaining uncertain. The management of women with polycystic ovary syndrome should focus on the specific needs of the individual, and may change according to different stages of the life course. In view of the clinical manifestations of the condition, there is recent debate about whether the current name is misleading, and whether the condition should be renamed as metabolic reproductive syndrome.

    Full Text Available Background Polycystic ovary syndrome (PCOS is the most common cause of oligoovulation and anovulation in general population and in females with infertility. Objectives The purpose of this study was to compare the efficacy of ovarian laparoscopic drilling procedure (LOD in females with PCOS, resistant to treatment with estradiol (E2 level less than 40 pg/mL versus more than 40 pg/mL. Materials and Methods Females with PCOS, resistant to drug for ovary stimulation, were grouped based on the Estradiol levels of ≤ 40 pg/mL (n = 13 and > 40 pg/mL (n = 15. To survey the ovulation, continuing spontaneous ovulation and cumulative pregnancy rate, ovarian laparoscopic drilling was carried out after the analysis of serum E2. Results There was significant difference in the average starting time of ovulation and continuing spontaneous ovulation of cases with PCOS with E2 levels > 40 pg/mL, compared with ones with E2 ≤ 40 pg/mL (P = 0.029, P = 0.05, respectively. Significant differences were also found in pregnancy rates of cases with PCOS with E2 levels > 40 pg/mL compared with ones with E2 ≤ 40 pg/mL (P = 0.05. Conclusions This study revealed that LOD in females with PCOS with a serum E2 > 40 pg/mL was sufficient and safe to trigger development of ovarian follicles followed by clinical pregnancy.

    Background. Polycystic ovary syndrome (PCOS) is associated with chronic oligo-anovulation and high circulating sex hormone levels. Women with PCOS have an increased risk of developing endometrial cancer. In anovulatory women with PCOS a positive relationship between endometrial thickness and endometrial hyperplasia has been observed. Uterine peristalsis, which has been suggested to be of importance for female fertility, has not previously been studied in PCOS. Purpose. To assess whether women with PCOS have altered endometrial thickness, uterine wall morphology, and peristalsis. Material and Methods. In this prospective case-control study 55 women with PCOS (mean age, 29.5 years {+-} 4.5 SD) and 28 controls (27.6 {+-} 3.2) were examined using magnetic resonance imaging (MRI), assessing thickness of endometrium, junctional zone (JZ), and myometrium, and evaluating the occurrence, frequency (waves/min), strength (amplitude), pattern, and direction of peristalsis. Uterine morphology was also assessed by transvaginal ultrasonography (TVUS). Results. The endometrium was thinner in PCOS with oligo-amenorrhea compared to controls, also after adjustments for age and BMI (adjusted P = 0.043). There was no difference in thickness of the JZ or the myometrium in cases versus controls. Uterine peristalsis was less commonly observed in women with PCOS than in controls (adjusted P = 0.014). Conclusion. There were no differences in myometrial morphology between PCOS and controls, but the endometrium was thinner in PCOS with oligo-amenorrhea. Based on cine MRI, uterine peristalsis was less common in PCOS than in controls.

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age and is associated with various metabolic perturbations, in addition to chronic anovulation and factors related to androgen excess. In general, women live longer than men and develop cardiovascular disease at an older age. However, women with PCOS, as compared with age- and body mass index-matched women without the syndrome, appear to have a higher risk of insulin resistance, hyperinsulinemia, glucose intolerance, dyslipidemia, and an increased prothrombotic state, possibly resulting in a higher rate of type 2 diabetes mellitus, fatty liver disease, subclinical atherosclerosis, vascular dysfunction, and finally cardiovascular disease and mortality. Further alterations in PCOS include an increased prevalence of sleep apnea, as well as various changes in the secretion and/or function of adipokines, adipose tissue-derived proinflammatory factors and gut hormones, all of them with direct or indirect influences on the complex signaling network that regulates metabolism, insulin sensitivity, and energy homeostasis. Reviews on the cardiometabolic aspects of PCOS are rare, and our knowledge from recent studies is expanding rapidly. Therefore, it is the aim of the present review to discuss and to summarize the current knowledge, focusing on the alterations of cardiometabolic factors in women with PCOS. Further insight into this network of factors may facilitate finding therapeutic targets that should ameliorate not only ovarian dysfunction but also the various cardiometabolic alterations related to the syndrome.

Results of the survey of women included in this study strongly support the negative impact of obesity on the functional state of the reproductive system, evidenced by the high incidence of anovulation, rhythm disturbances of menstruation (amenorrhea up to, infertility. Conclusions. The obtained results once again confirm the high efficacy and safety of sibutramine to reduce body mass, suggest correction of metabolic, hormonal disorders and positive impact on women's reproductive health. This allows us to consider the use of sibutramine in women with PCOS and obesity as a way to restore the endocrine function of the reproductive system.

    Polycystic ovary syndrome (PCOS) is a common endocrine system disorder among women of reproductive age. In several cases, PCOS women show infertility or subfertility and other metabolic alteration, such as insulin resistance (InsR), dyslipidaemia, hyperinsulinemia and obesity. Despite the aetiology of the syndrome is still far from be elucidated, it could be considered the result of concurrent endocrine modifications, lifestyle factors and genetic background. In particular, accumulating evidence suggests that InsR and compensatory hyperinsulinemia play a pivotal pathogenic role in the hyperandrogenism of many PCOS phenotypes, which in turn have a clear detrimental effect on chronic anovulation. Different forms of fasting, such as intermittent fasting (IF, including alternate day fasting, or twice weekly fasting, for example) and periodic fasting (PF, lasting several days or longer every 2 or more weeks) are currently being tested in several in vitro and in vivo studies. Changes in the circulating levels of Insulin Growth Factor-1 (IGF-1), Insulin-like Growth Factor-Binding Protein 1 (IGFBP1), glucose and insulin are typical effects of fasting which may play a key role on aging and metabolic homeostasis. Considering the paramount importance of InsR and compensatory hyperinsulinemia, different fasting regimens can reduce IGF-1, IGFBP1, glucose and insulin levels and consequently have beneficial effects on ovarian function, androgen excess and infertility in PCOS women.

    Functional hypothalamic amenorrhea (FHA) is a form of anovulation, due to the suppression of hypothalamic-pituitary-ovarian axis, not related to identifiable organic causes. Like adolescents with anorexia nervosa (AN), subjects with FHA show dysfunctional attitudes, low self-esteem, depressive mood, anxiety and inability to cope with daily stress. The aim of the study is to examine similarities and differences between FHA and AN in terms of clinical profiles and psychological variables. 21 adolescents with FHA, 21 adolescents with anorexia nervosa, and 21 healthy adolescents were included in the study. All the teenagers completed a battery of self-administered psychological tests for the detection of behaviors and symptoms attributable to the presence of an eating disorder (EDI-2), depression (CDI), and alexithymia (TAS-20). Different from healthy controls, subjects with FHA and with AN shared common psychopathological aspects, such as maturity issues, social insecurity and introversion, a tendency to depression, excessive concerns with dieting, and fear of gaining weight. Nevertheless, adolescents with AN presented a more profound psychopathological disorder as observed at test comparisons with subjects with FHA. Results show a clinical spectrum that includes AN and FHA and suggest the necessity to treat FHA with a multidisciplinary approach for both organic and psychological aspects.

    Full Text Available Background: Cyclooxygenase 2 is a key enzyme which converts arachidonic acid into prostaglandins. Cyclooxygenase 2 is triggered by inflammatory stimuli, such as cytokines. Its expression increases in tumors and Alzheimer's disease and ovarian hyperstimulation syndrome. Polycystic ovarian syndrome is a heterogeneous disease characterized by pathological angiogenesis and chronic anovulation. In the present study, the probable role of cyclooxygenase 2 in Wistar rats with polycystic ovarian syndrome was investigated.Methods: Thirty female Wistar rats (170-200 gr were equally divided into three groups: 2 mg estradiol valerate was intramuscularly administered to each rat in the experiment group or group 1; the rats in group 2 were regarded as the sham group and received sesame oil injections and group 3 or the control group received no injections. After 60 days of treatment, animals were anaesthetized with chloroform and killed by decapitation. Ovaries were collected for histological and immunohistochemical evaluations. All the experiments were repeated three times.Results: Morphologically, ovaries from the control group exhibited follicles in various stages of development and many fresh corpus luteum. In estradiol valerate group small follicles in early development were observed in addition to follicles showing evidence of atresia and many large cysts with thickened theca cell layer. Corpus luteum was rare or absent in group 2. The immunohistochemical analysis for cyclooxygenase 2 expression showed an increased expression of cyclooxygenase 2 enzyme in group 1.Conclusion: The results suggested the involvement of cyclooxygenase 2 in the progression to polycystic ovarian syndrome in a rat model.

    Polycystic ovary syndrome (PCOS) is a complex syndrome characterized by reproductive and metabolic implications. Lifestyle changes, such as diet and exercise, are considered first-line treatment for women affected by PCOS. Pharmacologic treatments target the hormonal and metabolic dysregulations associated to the disease such as insulin resistance, anovulation, hirsutism and menstrual irregularities. To focus on the role of inositol isoforms, as well as Mediterranean and ketogenic diets, as possible therapeutic strategies in PCOS women. Narrative overview, synthesizing the findings of literature retrieved from searches of computerized databases. Accumulating evidence suggests that two inositol isoforms, myo- and D-chiro-, may play a pivotal role in re-addressing both hormonal and metabolic parameters toward homeostasis, counteracting the symptoms and signs typical of this syndrome. In addition, studies focused on Mediterranean and ketogenic diet provided positive results in patients affected by obesity and type 2 diabetes, so these dietetic regimens could represent a fascinating dietetic treatment for the management of PCOS. Both the isoforms of inositol are effective in improving ovarian function and metabolism in patients with PCOS. In spite of accumulating evidence, it is currently not possible to draw firm conclusion(s) about the efficacy of these interventions considering the severe bias due to different samples size, dose, and duration of intervention among the published studies on this topic. Furthermore, future longitudinal cohort studies along with prospective interventional trials may contribute to better clarify the role of Mediterranean and ketogenic diets in the treatment of PCOS.

    Despite the fact that sports organizations and legislators have introduced various mechanisms to discourage athletes from using performance and appearance enhancing substances a high percentage of athletes admits to their unabated application. In competitive athletics, bodybuilding and in recreational sports anabolic androgenic steroids (AAS) continue to be the substances most abused. This review summarizes the side effects of AAS abuse on organs and system functions in both sexes. High doses of AAS cause a significant increase of erythrocytes und haemoglobin concentration, which may lead to thromboembolism, intracardiac thrombosis and stroke. Long-term AAS abusers have a higher incidence of arrhythmias, atherosclerosis, concentric left-ventricular myocardial hypertrophy with impaired diastolic function and also sudden cardiac death. Changes of liver function and structure, up to hepatocellular carcinoma, have been described, mainly in cases of chronic misuse of 17α-alkylated AAS. Sleeplessness, increased irritability, depressive mood status are often observed in AAS abuse. In former AAS abusers depression, anxiety and melancholy may persist for many years. Due to negative feedback in the regulation of the hypothalamic-pituitary-gonadal axis AAS can cause reversible suppression of spermatogenesis up to azoospermia. In women the changes most often caused by AAS abuse are hirsutism, irreversible deepening of voice, dysmenorrhoea, secondary amenorrhoea with anovulation and infertility. AAS abuse notwithstanding, under clinical conditions testosterone remains the most important hormone for substitution therapy of male hypogonadism.

    Caloric restriction caused by undernutrition or over-exercise is increasingly common and has significant health consequences such as hypothalamic amenorrhea, infertility, attainment of low peak bone mass, and bone loss leading to fracture. In these patients, the pathophysiology of amenorrhea and bone loss is multifactorial, involving hormones that integrate the nutritional state with the hypothalamic-pituitary-ovarian axis, including leptin and possibly ghrelin. The pathophysiology of bone loss includes nutritional deficiencies, possibly estrogen deficiency, and direct and indirect effects of leptin on bone. Identifying patients at risk for low bone mineral density and fracture is important, as is screening with dual energy radiograph absorptiometry. Treatment has focused on oral contraceptive use, yet improved bone mineral density is marked by nutritional recovery and anovulation reversal. Therefore, resolving the nutrition deficiency should be the cornerstone of treatment. Cognitive-behavioral therapy aims for weight recovery, which can lead to reversal of amenorrhea and improvement in other associated metabolic abnormalities. During treatment, estradiol levels can be followed to assess hypothalamic-pituitary-ovarian recovery because estradiol secretion may increase well before ovulation occurs. In patients failing the above interventions, hormone replacement should be considered, but bone mineral density should be followed because patients may continue to lose bone despite treatment with oral contraceptives if nutrition is not improved.

    Polycystic ovary syndrome (PCOS) is a complex syndrome of unclear etiopathogenesis characterized by heterogeneity in phenotypic manifestations. The clinical phenotype of PCOS includes reproductive and hormonal aberrations, namely anovulation and hyperandrogenism, which coexist with metabolic disturbances. Reflecting the crosstalk between the reproductive system and metabolic tissues, obesity not only deteriorates the metabolic profile but also aggravates ovulatory dysfunction and hyperandrogenism. Although the pathogenesis of PCOS remains unclear, the syndrome appears to involve environmental and genetic components. Starting from early life and extending throughout lifecycle, environmental insults may affect susceptible women who finally demonstrate the clinical phenotype of PCOS. Diet emerges as the major environmental determinant of PCOS. Overnutrition leading to obesity is widely recognized to have an aggravating impact, while another detrimental dietary factor may be the high content of food in advanced glycated end products (AGEs). Environmental exposure to industrial products, particularly Bisphenol A (BPA), may also exacerbate the clinical course of PCOS. AGEs and BPA may act as endocrine disruptors in the pathogenesis of the syndrome. PCOS appears to mirror the harmful influence of the modern environment on the reproductive and metabolic balance of inherently predisposed individuals.

    To highlight the recent developments in the field of menstrual function in sports and to provide an overview of our current understanding in regard to the pathophysiology, evaluation and management strategies of exercise-related reproductive dysfunction. A PUBMED search was carried out and all articles published from 1980 to 2010 with title words related to exercise, athletes, menstrual function and primary and secondary amenorrhea were reviewed. The review structure includes a pathophysiology overview, menstrual dysfunction among different athletic disciplines, clinical manifestations, evaluation and management strategies, with particular emphasis on recent data regarding the use of oral contraceptives and hormone replacement therapy. Exercise-related reproductive dysfunction appears to be multifactorial in origin and remains a diagnosis of exclusion. Recent findings underscore the endocrine role of adipose tissue in the regulation of metabolism and reproduction, providing further data on our understanding of the pathophysiology of exercise-related reproductive dysfunction. Clinical manifestations range from primary amenorrhea or delayed menarche to luteal phase deficiency, oligomenorrhea, anovulation and secondary amenorrhea. Amenorrhea constitutes the most serious clinical consequence and is associated with bone pathology. Early diagnosis, thorough evaluation and individualized management (ranging from diet and exercise, or behavior adjustments to pharmacologic treatment) should be achieved in order to preserve bone mass.

    Ghrelin is an endogenous appetite stimulant that may have a role in ovarian function. Women with polycystic ovary syndrome have anovulation and frequently weight management issues; however the associations between ghrelin and hormonal markers in polycystic ovary syndrome have not been well studied. In order to characterize the association between total ghrelin levels and ovarian function and the possible modification of this relationship by obesity, we examined total ghrelin levels and anti-mullerian hormone, total testosterone, and insulin in obese and non-obese women with and without polycystic ovary syndrome. Total ghrelin levels were lower in obese women with polycystic ovary syndrome (n = 45) compared to obese controls (n = 33) (p = 0.005), but similar in non-obese women with polycystic ovary syndrome (n = 20) compared to non-obese controls (n = 21) (p = NS). In the obese polycystic ovary syndrome group, anti-mullerian hormone was associated with ghrelin levels independent of age, insulin, and total testosterone (p = 0.008). There was no association between total ghrelin and anti-mullerian hormone levels in non-obese women with polycystic ovary syndrome, non-obese controls, or obese controls (p = NS). Our results provide evidence for a potential relationship between ghrelin and ovarian function in obese women with polycystic ovary syndrome that was not observed in non-obese women with polycystic ovary syndrome or controls.

    Polycystic Ovarian syndrome (PCOS) is a major cause of infertility in females of reproducing age and is typified by oligo-anovulation, hyperandrogenism, hirsutism and polycystic ovaries. FSHR gene located on chromosome 2 p21 is responsible for the normal follicular development and any deletion or mutation in the gene affects the interaction of FSH with its receptor. Thus, it becomes the candidate gene for PCOS study. Inactivating mutation in FSHR gene limits the receptor’s function by creating a complete block, changing the receptor-ligand complex or the basic hormone signal transduction.To screen the inactivating mutations in Exon 6 and Exon 10E of FSHR gene in women diagnosed with PCOS.PCR-RFLP analysis indicated that there were no inactivating mutations found in Exon 6 and Exon 10E. Variations in hormone levels were seen amongst the PCOS patients. There were no inactivating mutations found in FSHR gene of the women diagnosed with PCOS according to the Rotterdam criteria in Vellore population.

    Our aim was to investigate the percentage occurrence of different phenotypes of polycystic ovary syndrome (PCOS) in a Bulgarian population, and their clinical, metabolic and hormonal characteristics. The study included 110 women with PCOS, diagnosed according to the Europian Society of Human Reproduction & Embriology/American Society for Reproductive Medicine criteria. The women were divided into four phenotypes: hyperandrogenism (HA) + oligo-/ anovulation (OA) + polycystic ovaries at ultrasound (PCO) ( full-blown syndrome, phenotype A); HA + OA (former Institute of Health definition, phenotype B); OA + PCO (phenotype C); and HA + PCO (phenotype D). Serum levels of testosteron, immune-reactive insulin, sex hormone-binding globulin, dehydroepiandrosterone sulfate and lipid metabolism parameters were measured. Free androgen index and homeostasis model assessment of insulin resistance were calculated. Body mass index and waist- to--hip ratio were assessed. The percentage of phenotypes A, B, C and D in a Bulgarian Population are 53.6%, 12.8%, 11%, 22.6% respectively. The women with the classical form of PCOS (phenotypes A and B) were more obese, had more strongly expressed hyperandrogenemia, and were more insulin--resistant compared with the women of phenotypes C and D. There is a significant difference in anthropometric, hormonal and metabolic indices between the classical form and the clinical variants of PCOS in the studied Bulgarian population.

    Any amenorrhoea noticed outside pregnancy, lactation and menopause periods might be of organic or functional origin. Today, non organic amenorrhoea are either called hypothalamic amenorrhoea, more exactly supra hypothalamic amenorrhoea; functional amenorrhoea--this definition being characterized by its lack of any anatomic substratum; or, psychogenic amenorrhoea--an etiologic definition. Like any amenorrhoea, functional or psychogenic amenorrhoea is the consequence of either anovulation or endometrial hypotrophy. Neuroendocrine sciences do open new exciting research perspectives but other ways all the more promising since hormonal mechanics would not be the explanation. Work on the unconscious is indeed the other road leading to these psychogenic amenorrhoea. The term "psychogenic"--of psychological origin--does not mean of unknown origin, provided we recognize the strong link between psyche and soma. Treatment for this kind of amenorrhoea is twofold: medical and psychotherapeutic. Even though psychological etiology is obvious, clinical examination must be rigorous and completed by complementary exams which will guide the therapeutics. This is reassuring to the patient for the gynaecologist she chose to consult is implied, and not the psychotherapist. This reassures us too, because what we care for, as doctors, is first of all the body. Psychotherapeutic support can be provided by the general practitioner or the gynaecologist, both with psychosomatics training, but a multidisciplinary approach must often be worked out.

    Functional hypothalamic amenorrhea (FHA) is one of the most common causes of secondary amenorrhea. There are three types of FHA: weight loss-related, stress-related, and exercise-related amenorrhea. FHA results from the aberrations in pulsatile gonadotropin-releasing hormone (GnRH) secretion, which in turn causes impairment of the gonadotropins (follicle-stimulating hormone and luteinizing hormone). The final consequences are complex hormonal changes manifested by profound hypoestrogenism. Additionally, these patients present mild hypercortisolemia, low serum insulin levels, low insulin-like growth factor 1 (IGF-1) and low total triiodothyronine. The aim of this work is to review the available data concerning the effects of FHA on different aspects of women's health. Functional hypothalamic amenorrhea is related to profound impairment of reproductive functions including anovulation and infertility. Women's health in this disorder is disturbed in several aspects including the skeletal system, cardiovascular system, and mental problems. Patients manifest a decrease in bone mass density, which is related to an increase in fracture risk. Therefore, osteopenia and osteoporosis are the main long-term complications of FHA. Cardiovascular complications include endothelial dysfunction and abnormal changes in the lipid profile. FHA patients present significantly higher depression and anxiety and also sexual problems compared to healthy subjects. FHA patients should be carefully diagnosed and properly managed to prevent both short- and long-term medical consequences.

    The American Society for Reproductive Medicine, the European Society of Endocrinology, and the Pediatric Endocrine Society. This guideline was funded by the Endocrine Society. To formulate clinical practice guidelines for the diagnosis and treatment of functional hypothalamic amenorrhea (FHA). The participants include an Endocrine Society-appointed task force of eight experts, a methodologist, and a medical writer. This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation approach to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies. One group meeting, several conference calls, and e-mail communications enabled consensus. Endocrine Society committees and members and cosponsoring organizations reviewed and commented on preliminary drafts of this guideline. FHA is a form of chronic anovulation, not due to identifiable organic causes, but often associated with stress, weight loss, excessive exercise, or a combination thereof. Investigations should include assessment of systemic and endocrinologic etiologies, as FHA is a diagnosis of exclusion. A multidisciplinary treatment approach is necessary, including medical, dietary, and mental health support. Medical complications include, among others, bone loss and infertility, and appropriate therapies are under debate and investigation. Copyright © 2017 Endocrine Society

  1. Biocultural perspectives on women's health.

    1997-04-01

    During the 1997 meeting of the American Association for the Advancement of Science, a session was devoted to biocultural perspectives on women's health in developing countries. The topics covered included female circumcision conducted as part of the traditional wedding ceremony of the Rendille people of Kenya and the deleterious effect of sociocultural factors such as acceptance of premarital sexual intercourse and early child-bearing on the health of adolescent girls in West Africa. A study in Bangladesh sought information on women's health during pregnancy and lactation. Using 19,000 paired questionnaires and urine samples from 493 women representing all reproductive states, pregnancy-related sickness (such as nausea and vomiting) was correlated to hormone levels, maternal age, and fetal loss. Preliminary results contradict a popular belief that incidence of pregnancy-related sickness is associated with a lowered risk of early fetal loss. Another study in Bangladesh revealed that previous research indicating that women in Bangladesh experience menopause eight years sooner than US women was inaccurate. The two-year earlier onset of menopause found in Bangladesh is likely caused by stress-related anovulation. A preliminary literature review has also shown that Bangladeshi women lack significant amounts of phytoestrogens in their diet. Improved knowledge of biocultural factors is sought as a prerequisite for improving medical treatment in developed and developing countries.

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive aged women and is characterized by two of the following three features: oligoovulation or anovulation, clinical and/or biochemical signs of hyperandrogenism, or polycystic ovaries. It has been demonstrated that PCOS includes a complex number of systemic symptoms in addition to symptoms related to the reproductive apparatus. It has been associated with obesity, metabolic syndrome, type 2 diabetes and an increased risk of cardiovascular disease. Several clinical and basic studies have investigated the link between PCOS and the cardiovascular disease risk, which seems to be due to blunted lipid/glucose metabolism, hypertension, and systemic inflammatory and coagulation disorders. Therefore, the current manuscript aims to review the main findings on PCOS and obesity/obesity-related disease (glucose derangements and cardiovascular disease risk factors). Although there are no long-term data on the morbidity and mortality for cardiovascular disease in PCOS, it is advisable to perform a careful metabolic and cardiovascular assessment in women with PCOS in order to tailor the most suitable strategy to prevent cardiovascular disease.

    Full Text Available Introduction. We evaluated the effects of a therapy that combines myo-inositol (MI and D-chiro-inositol (DCI in young overweight women affected by polycystic ovary syndrome (PCOS, characterized by oligo- or anovulation and hyperandrogenism, correlated to insulin resistance. Methods. We enrolled 46 patients affected by PCOS and, randomly, we assigned them to two groups, A and B, treated, respectively, with the association of MI plus DCI, in a 40 : 1 ratio, or with placebo (folic acid for six months. Thus, we analyzed pretreatment and posttreatment FSH, LH, 17-beta-Estradiol, Sex Hormone Binding Globulin, androstenedione, free testosterone, dehydroepiandrosterone sulphate, HOMA index, and fasting glucose and insulin. Results. We recorded a statistically significant reduction of LH, free testosterone, fasting insulin, and HOMA index only in the group treated with the combined therapy of MI plus DCI; in the same patients, we observed a statistically significant increase of 17-beta-Estradiol levels. Conclusions. The combined therapy of MI plus DCI is effective in improving endocrine and metabolic parameters in young obese PCOS affected women.

    Full Text Available Polycystic ovary syndrome (PCOS is the most common endocrinopathy affecting women, and a leading cause of female infertility worldwide. Defined clinically by the presence of hyperandrogenemia and oligomenorrhoea, PCOS represents a state of hormonal dysregulation, disrupted ovarian follicle dynamics, and subsequent oligo- or anovulation. The syndrome’s prevalence is attributed at least partly to a well-established association with obesity and insulin resistance (IR. Indeed, the presence of severe PCOS in human genetic obesity and IR syndromes supports a causal role for IR in the pathogenesis of PCOS. The molecular mechanisms underlying this causality, however, as well as the important role of hyperandrogenemia, remain poorly elucidated. As such, treatment of PCOS is necessarily empirical, focusing on symptom alleviation. The generation of knockout and transgenic rodent models of obesity and IR offer a promising platform in which to address mechanistic questions about reproductive dysfunction in the context of metabolic disease. The impact of primary perturbations in rodent gonadotrophin or androgen signaling has been similarly interrogated. The insights gained from such models, however, have been limited by the relatively poor fidelity of rodent models to human PCOS. In this minireview we evaluate the ovarian phenotypes associated with rodent models of obesity and IR, including the extent of endocrine disturbance, ovarian dysmorphology and subfertility. We compare them to both human PCOS and other animal models of the syndrome (genetic and hormonal, explore reasons for their discordance and consider the new opportunities that are emerging to better understand and treat this important condition.

    Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women of reproductive age. It is characterized by chronic anovulation, hyperandrogenism, and insulin resistance. It is the main cause of infertility due to the menstrual dysfunction and metabolic disorders. Women with PCOS also have an increased cardiovascular risk because of dyslipidemia and insulin resistance. So far, we have a lot of information about the etiology of PCOS, and many steps forward have been made about the diagnosis of this syndrome, but there is still no certainty about the therapy. Myo-inositol (MI) and D-chiro-inositol, two inositol stereoisomers, have been proven to be effective in PCOS treatment. However, only MI has been shown to have beneficial effects on reproductive function, whereas the administration of MI/D-chiro-inositol, in the physiological plasma ratio (i.e., 40:1) ensures better clinical results, such as the reduction of insulin resistance, androgens' blood levels, cardiovascular risk and regularization of menstrual cycle with spontaneous ovulation.

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women in fertile age. It is an endocrine and metabolic disorder characterized by oligo-anovulation, hyperandrogenism and insulin-resistance. Various therapeutic approaches have been attempted in PCOS, including diet and the use of pharmacological agents such as oral contraceptives (OCs) or anti-androgens. Recently, the introduction of inositol in the treatment plan has proved to be as reasonable as useful in countering the endocrine-metabolic disorders of this syndrome. The aim of our study was to compare the clinical, endocrine and metabolic response after 6 months of therapy in 137 PCOS women characterized by oligomenorrhea and/or acne and/or mild hirsutism and insulin-resistance. The patients were treated with myo-inositol or with D-chiro-inositol or with placebo. Our study showed that both myo-inositol (MI-PG) and D-chiro inositol (DCI-PG) treatments are able to significantly improve the regularity of the menstrual cycle, the Acne Score, the endocrine and metabolic parameters and the insulin-resistence in young, overweight, PCOS patients. Definitely, we assumed that both treatments with myo-inositol and with D-chiro inositol could be proposed as a potential valid therapeutic approach for the treatment of patients with PCOS. Additionally, further examination and for a longer period of treatment are needed.

    (8.3%). Higher uric acid levels were associated with increased odds of anovulation (odds ratio 2.39, 95% CI: 1.25, 4.56). LIMITATIONS, REASONS FOR CAUTION The change in uric acid levels among this cohort of healthy women was modest, and analysis was limited to two menstrual cycles. The women in this study were healthy and regularly menstruating, and as such there were few women with high uric acid levels and anovulatory cycles. WIDER IMPLICATIONS OF THE FINDINGS These findings demonstrate the importance of taking menstrual cycle phase into account when measuring uric acid in premenopausal women, and confirm the hypothesized beneficial lowering effects of endogenous E2 on uric acid levels. These findings suggest that there could be an underlying association affecting both sporadic anovulation and high uric acid levels among young, regularly menstruating women. Further studies are needed to confirm these findings and elucidate the connection between uric acid and reproductive and later cardiovascular health.

    Infertility is an important health issue which has been neglected in the developing countries. First test-tube babies (triplet) in Bangladesh were born on 30th May, 2001. Although there is no tertiary level infertility center in the public sector, several private centers have come up with the facilities. The objective of the study was to find i) the quality and quantity of infertility care in Bangladesh and ii) the cause of infertility in the attending patients iii) the treatment seeking behaviors iv) and the reasons for not taking treatment among the attending patients. There are now 10 tertiary level Infertility centers in Bangladesh. The information was collected in a preformed datasheet about the facilities and the profile of the patients and the treatment seeking behavior of the attending patients. Out of the ten centers two centers refused to respond and did not disclose their data. Around 16700 new patients are enrolled in a year in the responsive clinics. Five percent (5%) of the patients underwent ART, 7% of the patients gave only one visit, 84% of the patients completed their evaluation, 76% of the patients took treatment. Causes of infertility in the patients taking treatment were male factor in 36.4%, bilateral tubal block in 20.2%, PCOS and anovulation in 31.7%, endometriosis in 19.6%, unexplained in 10.95, combined in 3.5%, ovarian failure in 1.4%, testicular failure in 0.33%, congenital anomaly in 0.3%. The main reason for not taking treatment was financial constrainment. The quality and quantity of infertility care is dependent on the available resources and on the use of the resources by the patients. In developing countries the resources are merging and confined to specified areas which cannot meet the demand of their population. The study gives us the idea of the need and the demand of the services in the country.

    Full Text Available Polycystic ovary syndrome (PCOS is a common female endocrinopathy of unclear origin characterized by hyperandrogenism, oligo-/anovulation, and ovarian cysts. Women with PCOS frequently display overweight, insulin resistance, and systemic low-grade inflammation. We hypothesized that endotoxemia resulting from a leaky gut is associated with inflammation, insulin resistance, fat accumulation, and hyperandrogenemia in PCOS. In this pilot study, we compared the stool microbiome, gut permeability, and inflammatory status of women with PCOS and healthy controls.16S rRNA gene amplicon sequencing was performed on stool samples from 24 PCOS patients and 19 healthy controls. Data processing and microbiome analysis were conducted in mothur and QIIME using different relative abundance cut-offs. Gut barrier integrity, endotoxemia, and inflammatory status were evaluated using serum and stool markers and associations with reproductive, metabolic, and anthropometric parameters were investigated.The stool microbiome of PCOS patients showed a lower diversity and an altered phylogenetic composition compared to controls. We did not observe significant differences in any taxa with a relative abundance>1%. When looking at rare taxa, the relative abundance of bacteria from the phylum Tenericutes, the order ML615J-28 (phylum Tenericutes and the family S24-7 (phylum Bacteroidetes was significantly lower and associated with reproductive parameters in PCOS patients. Patients showed alterations in some, but not all markers of gut barrier function and endotoxemia.Patients with PCOS have a lower diversity and an altered phylogenetic profile in their stool microbiome, which is associated with clinical parameters. Gut barrier dysfunction and endotoxemia were not driving factors in this patient cohort, but may contribute to the clinical phenotype in certain PCOS patients.

    Full Text Available Polycystic ovary syndrome affects 5-10% of women in the developed world, making it the most common endocrine disorder among women of reproductive age. The symptoms typically associated with polycystic ovary syndrome: amenorrhea, oligomenorrhea, hirsutism, obesity, subfertility, anovulation and acne can lead to a significant reduction in female life quality.The aim of the study was to evaluate the effect of polycystic ovary syndrome on quality of life and marital sexual satisfaction. Fifty women with polycystic ovary syndrome were qualified to the study as the research group. The control group consisted of fourty healthy women. A specific questionnaire was used as a research tool in this study. It included the socio-demographic part, polycystic ovary syndrome's symptomatology and validated scales: Polish version of Short Form-36 Health Survey (SF-36 and Index of Sexual Satisfaction (ISS. The mean age of researched women was 28.9+/-5.6 years, and in the control group - 30.5+/-5.3 years (p>0.05. Quality of life parameters for women with polycystic ovary syndrome were lower than for the controls in the aspect of: general health (p<0.01, limitations due to physical health (p<0.05, limitations due to emotional problems (p<0.001, social functioning (p<0.01, energy/fatigue (p<0.001 and emotional wellbeing (p<0.01. Studied women showed worse marital sexual functioning (p<0.05. Marital sexual dysfunctions were diagnosed in 28.6% of women with polycystic ovary syndrome and in 10.5% of healthy women (p<0.05. Polycystic ovary syndrome decreases quality of life and marital sexual functioning among women. A negative effect of hirsutism severity on general well-being and marital sexual life is also observed.

    Subfertility is frequently encountered among female rheumatoid arthritis (RA) patients and has been associated with disease activity and antirheumatic drugs. However, little is known about the results of the fertility assessments in these women. Our aim was to study the outcome of fertility assessments in subfertile women with RA. A cross-sectional study was performed in a nationwide cohort of female RA patients who were pregnant or trying to conceive between 2002 and 2010 (Pregnancy-Induced Amelioration of Rheumatoid Arthritis Study). Patients who had given consent for future contact (n = 260) received a questionnaire on reproductive history, fertility examinations, and fertility treatments. Medical files were obtained from attending gynecologists. A completed questionnaire was returned by 178 women (68%), of whom 96% had ended their efforts to conceive. Eighty-two subjects (46%) had at least 1 subfertile episode, and for 61 women a diagnosis for subfertility was available. Unexplained subfertility (48%) and anovulation (28%) were the most common gynecologic diagnoses, and both occurred more often in RA patients than reported in the general population. Women with unexplained subfertility more often used nonsteroidal antiinflammatory drugs (NSAIDs) during the periconceptional period. Seventeen percent of all pregnancies were conceived after fertility treatments. Fertility treatments had equal or higher pregnancy rates in RA compared to other subfertile populations. Unexplained subfertility is more often diagnosed in subfertile female RA patients than in the general population, and is related to periconceptional NSAID use. Despite the higher incidence of subfertility in women with RA, the outcome of fertility treatments in these women appears favorable. © 2016 The Authors.

    Objective: To compare different treatment regimens on pregnancy rate and outcome in patients with anovulatory infertility. Patients and Methods: A prospective observational study was conducted on patients with infertility due to anovulation. Patients treated with clomiphene citrate (CC) 50/100 mg/day from 2nd to 6th day of menstrual cycle (MC) (n = 38), short gonadotropin-releasing hormone (GnRH) agonist regimen (leuprolide [0.5 mg subcutaneous] + recombinant follicle-stimulating hormone [rFSH] [225 IU intramuscular [IM] from 2nd to 10th day of MC [n = 32]), long GnRH agonist regimen (leuprolide from 21st day followed by leuprolide + rFSH from 2nd to 10th day of MC [n = 19]), and antagonist regimen (human menopausal gonadotropin [hMG] [150 IU IM] from 2nd day followed by hMG + cetrorelix from 7th to 10th day of MC) (n = 6) were recruited and followed up for follicular size, endometrial thickness, and pregnancy test. Data were analyzed using appropriate statistical test andP < 0.05 was considered statistically significant. Results: A significant increase in follicular diameter and endometrial thickness was observed in patients treated with gonadotropin regimens as compared to CC alone (P < 0.0001). The highest number of positive pregnancy test with ultrasonographic evidence of gestational sac was observed with leuprolide + rFSH (long regimen) (10/19, 52.6%) followed by leuprolide + rFSH (short regimen) (13/32, 40.6%) while least in antagonist regimen (2/6, 33.3%) and CC (1/38, 2.63%). All regimens were well tolerated. Conclusion: Treatment outcome was better with long agonist regimen. PMID:29081619

    PCOs is a heterogeneous disorder with anovulation/oligo ovulation usually taken as oligo menorrhoea or amenorrhoea, hyperandrogenemia, hirsutism, acne, androgen alopecia and polycystic ovaries as the key diagnostic feathers. The study was undertaken to investigate the possible protective and ameliorating effects of GABA in Letrozole induced PCOS model in rats by targeting insulin resistance. PCOs in Adult female rat was induced by the daily gastric administration of letrozole (1 mg/kg/day) in CMC (0.5%) for 36 days. Rats were given metformin (2 mg/kg), GABA (100 mg/kg/day) and GABA (500 mg/kg/day) along with letrozole. One group severed as vehicle control. On the 37 day, the animals were euthanized, and anthropometrical, biochemical (glucose, insulin, lipids, testosterone, Estradiol, Progesterone, oral glucose tolerance test, total protein content in ovary, cholesterol level, triglyceride, HDL, LDL), Antioxidants (CAT, POD, GSR, ROS, GSH, TBARS), and histopathological evaluation of ovaries were carried out. Daily colpocytological examination was also carried out until the termination. Both the doses of GABA significantly reduced body weight, body mass index and testosterone. While the levels of CAT, SOD, POD and Estradiol (E 2 ) were significantly increased in the both doses of GABA. A favourable lipid profile, normal glucose tolerance, and decreased in the percentage of estrus smears were observed. Histopathological examination of ovary revealed a decreased in the number of cystic follicles, and decreased in the adipocytes respectively. The effects observed with GABA were comparable to that with metformin. The results suggest that GABA treatment has shown protective effect in PCOs and provide beneficial effect either by reducing insulin resistance or by inducing antioxidant defence mechanisms.

    Polycystic ovary syndrome (PCOS) is a combination of chronic anovulation, obesity, and hyperandrogenism and can affect sexual function in women of reproductive age. It is also associated with endometrial cancer. Our aim was to evaluate the frequency and predisposing factors of sexual dysfunction in PCOS patients. In this cross-sectional study, 16 married women with a definite diagnosis of PCOS were recruited. Sexual function was assessed in the domains of desire, arousal, lubrication, orgasm, satisfaction and pain using the female sexual function index (FSFI) questionnaire. Patients were also assessed for mental health using the depression, anxiety and stress (DASS-21) questionnaire. Presence of hirsutism was assessed using the Ferriman-Gallwey (FG) scoring system. Demographic data were obtained from patients during in-person interview. Sexual dysfunction was present in 62.5% of patients with the domains of arousal and lubrication particularly affected (93.8% and 87.5%, respectively). Patients with symptoms of depression and anxiety were significantly more likely to suffer sexual dysfunction than those without these symptoms (p=0.04 and p=0.03 respectively). Patients with stress symptoms reported higher orgasm dysfunction than those without (p=0.02). No significant difference in any of the FSFI score domains was observed between patients with and without hirsutism. PCOS patients markedly suffer from sexual dysfunction and therefore it seems appropriate to be screened for intervention. Poor mental health conditions that may be the result of infertility or other complications of PCOS should also be considered as curable causes of sexual dysfunction in these patients.

The first-line treatment option for overweight/obese women with PCOS is diet and lifestyle interventions. However, optimal dietary guidelines are missing, with very little research having been done in this area. This paper presents the findings from a qualitative study (using semistructured interviews of ten obese women who had PCOS and who had used LighterLife Total (LLT, a commercial weight loss program which utilizes a very low-calorie diet in conjunction with behavioral change therapy underpinned by group support. We investigated the women’s history of obesity, their experiences of other diets compared with LLT, and the on-going impact that this has had on their lives. Findings show that most women reported greater success using this weight loss program in terms of achieving and maintaining weight loss when compared with other diets. Furthermore, all the women nominated LLT as their model weight loss intervention with only a few modifications. Keywords: PCOS, obesity, weight loss, diet

  16. Crowding and Follicular Fate: Spatial Determinants of Follicular Reserve and Activation of Follicular Growth in the Mammalian Ovary.

    Full Text Available Initiation of growth of resting ovarian follicles is a key phenomenon for providing an adequate number of mature oocytes in each ovulation, while preventing premature exhaustion of primordial follicle reserve during the reproductive lifespan. Resting follicle dynamics strongly suggest that primordial follicles are under constant inhibitory influences, by mechanisms and factors whose nature remains ill defined. In this work, we aimed to assess the influence of spatial determinants, with special attention to clustering patterns and crowding, on the fate of early follicles in the adult mouse and human ovary. To this end, detailed histological and morphometric analyses, targeting resting and early growing follicles, were conducted in ovaries from mice, either wild type (WT or genetically modified to lack kisspeptin receptor expression (Kiss1r KO, and healthy adult women. Kiss1r KO mice were studied as model of persistent hypogonadotropism and anovulation. Different qualitative and quantitative indices of the patterns of spatial distribution of resting and early growing follicles in the mouse and human ovary, including the Morisita's index of clustering, were obtained. Our results show that resting primordial follicles display a clear-cut clustered pattern of spatial distribution in adult mouse and human ovaries, and that resting follicle aggrupation is inversely correlated with the proportion of follicles initiating growth and entering into the growing pool. As a whole, our data suggest that resting follicle crowding, defined by changes in density and clustered pattern of distribution, is a major determinant of follicular activation and the fate of ovarian reserve. Uneven follicle crowding would constitute the structural counterpart of the major humoral regulators of early follicular growth, with potential implications in ovarian ageing and pathophysiology.

    There are complex causal associations between mental disorders, fertility treatment, fertility treatment outcome and infertility per se. Eating disorders cause endocrine disturbances, anovulation and thereby infertility, and research has shown that infertility as well as unsuccessful assisted reproductive technology (ART) treatment are potential risk factors for developing a depression on a long-term basis. Despite the fact that worldwide more than 400 000 ART treatment cycles are performed every year, the causal associations between mental disorders, use of medication for mental disorders and ART treatment in both sexes have only been sparsely explored. The main objective of this national register-based cohort study is to assess women's and men's mental health before, during, and after ART treatment in comparison with the mental health in an age-matched population-based cohort of couples with no history of ART treatment. Furthermore, the objective is to study the reproductive outcome of ART treatment among women who have a registered diagnosis of a mental disorder or have used medication for mental disorders prior to ART treatment compared with women in ART treatment without a mental disorder. We will establish the Danish National ART-Couple (DANAC) cohort including all women registered with ART treatment in the Danish in vitro fertilisation Register during 1994-2009 (N=42 915) and their partners. An age-matched population-based comparison cohort of women without ART treatment (n=215 290) and their partners will be established. Data will be cross-linked with data from national registers on psychiatric disorders, medical prescriptions for mental disorders, births, causes of deaths and sociodemographic data. Survival analyses and other statistical analyses will be conducted on the development of mental disorders and use of medication for mental disorders for women and men both prior to and after ART treatment.

  18. Is foetal hyperexposure to androgens a cause of PCOS?

    Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting reproductive-aged women. The pathophysiology of this syndrome is still not completely understood but recent evidence suggests that the intra-uterine environment may be a key factor in the pathogenesis of PCOS, in particular, hyperexposure of the foetus to androgens. High concentrations of maternal serum testosterone during pregnancy have been shown to influence behaviour during childhood, the prevalence of autism disorders and anti-Mullerian hormone (AMH) concentrations in adolescence. They are also thought to re-programme the female reproductive axis to induce the features of PCOS in later life: oligo/anovulation, polycystic ovaries, hyperandrogenism and insulin resistance (IR). Support for this developmental theory for the aetiology of PCOS is gathering momentum, following results from first animal studies and now human data, which lend credence to many aspects of this hypothesis. In this review the recent available evidence is presented to support the hypothesis that hyperandrogenic changes in the intra-uterine environment could play a major part in the aetiological basis of PCOS. An extensive PubMED and MEDline database search was conducted. Relevant studies were identified using a combination of search terms: 'polycystic ovary syndrome', 'PCOS', 'aetiology', 'anti-Mullerian hormone', 'AMH', 'pathogenesis', 'kisspeptin', 'hyperandrogenism', 'insulin resistance', 'metabolic factors', 'placenta', 'developmental hypothesis', 'genetic and epigenetic origins'. A total of 82 studies were finally included in this review. There is robust evidence that a hyperandrogenic intra-uterine environment 'programmes' the genes concerned with ovarian steroidogenesis, insulin metabolism, gonadotrophin secretion and ovarian follicle development resulting in the development of PCOS in adult life. Once the evidence supporting this hypothesis has been expanded by additional studies, the door would be open to

    Polycystic ovary syndrome (PCOS) is a common female endocrinopathy of unclear origin characterized by hyperandrogenism, oligo-/anovulation, and ovarian cysts. Women with PCOS frequently display overweight, insulin resistance, and systemic low-grade inflammation. We hypothesized that endotoxemia resulting from a leaky gut is associated with inflammation, insulin resistance, fat accumulation, and hyperandrogenemia in PCOS. In this pilot study, we compared the stool microbiome, gut permeability, and inflammatory status of women with PCOS and healthy controls. 16S rRNA gene amplicon sequencing was performed on stool samples from 24 PCOS patients and 19 healthy controls. Data processing and microbiome analysis were conducted in mothur and QIIME using different relative abundance cut-offs. Gut barrier integrity, endotoxemia, and inflammatory status were evaluated using serum and stool markers and associations with reproductive, metabolic, and anthropometric parameters were investigated. The stool microbiome of PCOS patients showed a lower diversity and an altered phylogenetic composition compared to controls. We did not observe significant differences in any taxa with a relative abundance>1%. When looking at rare taxa, the relative abundance of bacteria from the phylum Tenericutes, the order ML615J-28 (phylum Tenericutes) and the family S24-7 (phylum Bacteroidetes) was significantly lower and associated with reproductive parameters in PCOS patients. Patients showed alterations in some, but not all markers of gut barrier function and endotoxemia. Patients with PCOS have a lower diversity and an altered phylogenetic profile in their stool microbiome, which is associated with clinical parameters. Gut barrier dysfunction and endotoxemia were not driving factors in this patient cohort, but may contribute to the clinical phenotype in certain PCOS patients.

    Polycystic ovary syndrome (PCOS) is associated with hyperandrogenism, oligo-anovulation, polycystic ovaries and metabolic syndrome. Many researchers reported that PCOS often starts with menarche in adolescents. Presently available animal model focuses on ovarian but not metabolic features of PCOS. Therefore, we hypothesized that high-fat diet feeding to pre-pubertal female rats results in both reproductive and metabolic features of PCOS. Pre-pubertal female rats were divided into two groups: group I received normal pellet diet and group II received high-fat diet (HFD). In the letrozole study, adult female rats were divided into two groups: group I received 1% carboxy methyl cellulose and group II received 1 mg/kg letrozole orally. Oral glucose tolerance test, lipid profile, fasting glucose, insulin, estrus cycle, hormonal profile, ovary weight, luteinizing hormone (LH) receptor and follicle-stimulating hormone receptor expression were measured. Polycystic ovarian morphology was assessed through histopathological changes of ovary. Feeding of HFD gradually increase glucose intolerance and fasting insulin levels. Triglyceride level was higher in HFD study while total cholesterol level was higher in the letrozole study. Alteration in testosterone and estrogen levels was observed in both studies. LH receptor expression was upregulated only in HFD study. Histopathological changes like increase cystic follicle, diminished granulosa cell layer and thickened theca cell layer were observed in letrozole as well as HFD study. High-fat diet initiated at pre-puberty age in rats produces both metabolic disturbances and ovarian changes similar to that observed clinically in PCOS patients. Letrozole on the other hand induces change in ovarian structure and function. © 2018 Society for Reproduction and Fertility.

    Diet is proposed to contribute to androgen-related reproductive dysfunction. This study evaluated the association between dietary macronutrient intake, carbohydrate fraction intake, and overall diet quality on androgens and related hormones, including anti-Müllerian hormone (AMH) and insulin, in healthy, regularly menstruating women. This was a prospective cohort study from 2005 and 2007. The study was conducted at the University at Buffalo, western New York State, USA. Participants were 259 eumenorrheic women without a self-reported history of infertility, polycystic ovary syndrome (PCOS), or other endocrine disorder. A 24-hour dietary recall was administered 4 times per menstrual cycle, and hormones were measured 5 to 8 times per cycle for 1 (n = 9) or 2 (n = 250) cycles per woman (n = 509 cycles). Associations between the dietary intake of carbohydrates (starch, sugar, sucrose, and fiber), macronutrients, overall diet quality and hormones (insulin, AMH, and total and free testosterone), as well as the relationship of dietary intake with occurrences of high total testosterone combined with high AMH (fourth quartile of each), ie, the "PCOS-like phenotype," were assessed. No significant relationships were identified between dietary intake of carbohydrates, percent calories from any macronutrient or overall diet quality (ie, Mediterranean diet score) and relevant hormones (insulin, AMH, and total and free testosterone). Likewise, no significant relationships were identified between dietary factors and the occurrence of a subclinical PCOS-like phenotype. Despite evidence of a subclinical continuum of a PCOS-related phenotype of elevated androgens and AMH related to sporadic anovulation identified in previous studies, dietary carbohydrate and diet quality do not appear to relate to these subclinical endocrine characteristics in women without overt PCOS.

    Metabolic syndrome (MBS) is a common disorder and is thought to be extremely prevalent in polycystic ovary syndrome (PCOS). In the USA the prevalence of MBS in PCOS has been reported to be as high as 43-46% using Adult Treatment Panel III (ATP-III) criteria. Because of differences in diet, lifestyle and genetic factors, we postulated that the prevalence of MBS might not be as high in Italian women. This study sought to determine the prevalence of MBS in Italian women using both the ATP-III and the World Health Organization (WHO) criteria and to determine whether the prevalence is influenced by the way in which PCOS is diagnosed. Assessment of the prevalence of MBS in 282 women with PCOS, aged 18-40 years, living in western Sicily. Eighty-five age- and weight-matched normal women served as controls. Patients were divided into those with chronic anovulation and hyperandrogenism (classic PCOS; n = 225) and others with hyperandrogenism and polycystic ovaries but who were ovulatory (ovulatory PCOS; n = 57). A 75 g oral glucose tolerance test was carried out, as were lipid determinations; insulin resistance was assessed by the Quantitative Insulin-Sensitivity Check Index (QUICKI). We used ATP-III and WHO criteria to diagnose MBS. Using ATP-III criteria, the prevalence of MBS was 8.2% and using WHO criteria it was 16% in Italian women with PCOS. In controls, the prevalence was 2.4% using both methods. In classic PCOS patients, MBS was higher (8.9% by ATP-III, 17.3% by WHO) than in ovulatory PCOS (5% and 10.6% respectively). Body weight significantly modified prevalence rates. MBS is substantially higher in women with PCOS than in the general population, and the prevalence is higher in those women diagnosed by classic criteria. However, the prevalence of MBS in PCOS appears to be much lower in Italy than in the USA.

    Any insult that affects survival of ovarian antral follicles can cause abnormal estradiol production and fertility problems. Phthalate esters (PEs) are plasticizers used in a wide range of consumer and industrial products. Exposure to these chemicals has been linked to reduced fertility in humans and animal models. Di-(2-ethylhexyl) phthalate (DEHP) and mono-(2-ethylhexyl) phthalate (MEHP) decrease serum estradiol levels and aromatase (Arom) expression, prolong estrous cycles, and cause anovulation in animal and culture models. These observations suggest PEs directly target antral follicles. We therefore tested the hypothesis that DEHP (1-100 μg/ml) and MEHP (0.1-10 μg/ml) directly inhibit antral follicular growth and estradiol production. Antral follicles from adult mice were cultured with DEHP or MEHP, and/or estradiol for 96 h. During culture, follicle size was measured every 24 h as a measurement of follicle growth. After culture, media were collected for measurement of estradiol levels and follicles were subjected to measurement of cylin-D-2 (Ccnd2), cyclin-dependant-kinase-4 (Cdk4), and Arom. We found that DEHP and MEHP inhibited growth of follicles and decreased estradiol production compared to controls at the highest doses. DEHP and MEHP also decreased mRNA expression of Ccnd2, Cdk4, and Arom at the highest dose. Addition of estradiol to the culture medium prevented the follicles from DEHP- and MEHP-induced inhibition of growth, reduction in estradiol levels, and decreased Ccnd2 and Cdk4 expression. Collectively, our results indicate that DEHP and MEHP may directly inhibit antral follicle growth via a mechanism that partially includes reduction in levels of estradiol production and decreased expression of cell cycle regulators.

    Polycystic ovary syndrome (PCOS) is a common heterogeneous disorder that appears to have its origins during the peripubertal years. The diagnostic conundrum is that the typical clinical features, irregular menses and acne, occur during normal female puberty. Understanding the physiologic origins and molecular basis of the dysregulated hypothalamic-pituitary-gonadal axis in PCOS is fundamental to interrupting the distinctive vicious cycle of hyperandrogenism and chronic anovulation. Newer ultrasound technology with better spatial resolution has generated controversy regarding the optimal imaging criteria to define polycystic ovary morphology. Using such equipment, the Androgen Excess PCOS Society Task Force Report recommends a threshold of at least 25 follicles per ovary as the definition of polycystic ovary morphology. The implementation and results of genome-wide association studies has opened a new window into the pathogenesis of PCOS. Recent genome-wide association studies have identified several loci near genes involved in gonadotropin secretion, ovarian function, and metabolism. Despite the impediments posed by phenotypic and genetic heterogeneity among women with PCOS, investigation into one locus, the DENND1A gene, is providing insight into the ovarian steroidogenesis. Anti-Mullerian hormone (AMH) has long been recognized to play a major role in the ovarian dysfunction. Recent animal data implicate AMH in the neuroendocrine dysregulation by demonstrating AMH-stimulated increased gonadotropin releasing hormone and luteinizing hormone secretion. PCOS is a common complex multifaceted disorder associated with genetic and environmental influences affecting steroidogenesis, steroid metabolism, neuroendocrine function, insulin sensitivity, pancreatic β cell function, and alternative adaptations to energy excess. Current research into the genetics and pathophysiology is reviewed. The difficulties inherent in diagnosing PCOS in adolescent girls are discussed.

    Any abnormality of menstrual cycle makes women worried and requires proper evaluation. Oligomenorhea is one of the indicators of Polycystic Disease of the Ovary (PCO) which is associated not only with reproductive failure but it also has metabolic and cardiovascular complications. The recent study was conducted to find out the role of Pituitary Gonadotropins in the diagnosis. After diagnosing and finding out the cause for menstrual irregularities and chronic anovulation one can explain the prognosis and management of these disorders. Fifty patients were studied in the year 2005-06 in the outpatient department of Khyber Teaching Hospital Peshawar. A history Performa was duly completed in all subjects. Blood sample was collected for hormonal essay during first ten days of the cycle. Hormonal essay was performed by Microparticle enzyme immunoassay (MEIA) on AXSYM system of Abbott. Age ranged from 13-45 years, 82% of the women were infertile, 60% had infrequent periods and 22% of the women had amenorrhea, 30% patients were overweight while 48% were obese. Physical examination revealed hersuitism in 24%, acne in 8% and galactorrhea in 6% of the patients. Ultrasound examination showed classical picture of PCO in 28% patients while 32% women had multiple small follicles and 16 % women were devoid of follicles. Elevated LH levels were found in 36% women. FSH level were found normal in 64% patients while in 16% women the levels were in menopausal range. LH/FSH ratio of more than two was observed in 52% women. Prolactin level was raised in 22% women. TSH level was below normal in 16% and higher in 22% women. Hormonal essays are mandatory in the evaluation of women presenting with Oligomenorhea/amenorrhea and chronic anovulatory infertility for finding out the cause and explaining the prognosis of the disease to the patient.

    Full Text Available Abstract Background & aim: Polycystic ovary syndrome (PCOS is an endocrine failure leading to anovulation. TNFα is an effective factor in the regulation of normal functioning of the ovaries. High levels of TNFα causes PCOS is further. In this study, the effects of bumble bee venom (HBV on TNFα and other symptoms of ovarian PCOS were studied. Methods: In this experimental study, 60 female Wistar rats were divided into three groups: control, sham and experimental groups. The experimental group was injected with estradiol valerate-induced PCOS direction. Induced rats (PCOS were divided into two groups and treated with HBV. The treatment Group received 0.2mg of HBV for 10 consecutive days. Serum and ovarian tissue was collected from each of the four groups to compare the histological and changes in blood sugar levels. Results: A significant increase in ovarian PCOS weight was observed in the control group , whereas in the treated group with HBV rate fell (15.5 mg Glucose levels in PCOS was 256.5, the control group138, and the treatment group 158. Thickness of the theca layer of antral follicles in the treated group compared with PCOS showed a significant decrease (110 μm and 150 μm respectively. Immunohistochemical results showed increased TNFα factor in PCOS group than in the control group, whereas these levels in samples treated with HBV Reduced. Conclusion: The results of this study revealed that the beneficial effects of HBV in PCOS may be due to the inhibitory effect on factor TNFα.

    Full Text Available Objective of the study — to investigate the disorders of growth hormone (GH secretion in women with polycystic ovary syndrome (PCOS compared to patients with non-functional pituitary adenomas (NFPA. Under our supervision during period from September 2015 to March 2016, there were 15 female outpatients of childbearing age with PCOS and 15 — with NFPA. Average age of patients was 25.5 and 28.9 years, respectively. The duration of disease ranged from 7 months to 9 years. It was found that in both groups, there were neuroendocrine disorders typical for each pathology. So, in the first group of patients with PCOS, the following violations were most often: obesity, striae, acanthosis, аcne, hyperandrogenemia, hyperpolyme­norrhea, and in the second one — secondary amenorrhea, hyperprolactinemia, panhypopituitarism. In both groups, there was anovulation, as well as decline of GH and insulin-like growth factor‑1 (IGF‑1 secretion. In addition, patients with NFPA had significantly decreased basal levels of tropic hormones — GH, luteinizing hormone (LH and follicle-stimulating hormone (FSH on the background of hyperprolactinemia and normal values of IGF‑1, while in patients with PCOS, the levels of GH, LH, FSH were reduced on the background of hyperandrogenemia and IGF‑1 decline. Thus, it was found that in the group of patients with PCOS, there was the most significant reduction of basal IGF‑1 levels, whereas GH deficiency was less frequent. Patients with NFPA had panhypopituitarism, namely combined deficiency of GH, LH, FSH, thyroid stimulating hormone, while IGF‑1 deficiency was less frequent. Disorders of GH and IGF‑1 secretion identified in our study confirm the literature data that patients with PCOS have a reduction in the levels of GH and IGF‑1 on the background of hyperinsulinemia and hyperandrogenaemia.

    Polycystic ovarian syndrome (PCOS) is characterized by the presence of multiple follicular cysts, giving rise to infertility due to anovulation. This syndrome affects about 10% of women, worldwide. The exact molecular mechanism leading to PCOS remains obscure. RhoGTPase has been associated with oogenesis, but its role in PCOS remains unexplored. Therefore, we attempted to elucidate the Vav-Rac1 signaling in PCOS mice model. We generated a PCOS mice model by injecting dehydroepiandrosterone (DHEA) for a period of 20 days. The expression levels of Rac1, pRac1, Vav, pVav and Caveolin1 were analyzed by employing immuno-blotting and densitometry. The association between Vav and Rac1 proteins were studied by immuno-precipitation. Furthermore, we analyzed the activity of Rac1 and levels of inhibin B and 17β-estradiol in ovary using biochemical assays. The presence of multiple follicular cysts in ovary were confirmed by histology. The activity of Rac1 (GTP bound state) was significantly reduced in the PCOS ovary. Similarly, the expression levels of Rac1 and its phosphorylated form (pRac1) were decreased in PCOS in comparison to the sham ovary. The expression level and activity (phosphorylated form) of guanine nucleotide exchanger of Rac1, Vav, was moderately down-regulated. We observed comparatively increased expressions of Caveolin1, 17β-estradiol, and inhibin B in the polycystic ovary. We conclude that hyperandrogenization (PCOS) by DHEA diminishes ovarian Rac1 and Vav expression and activity along with an increase in expression of Caveolin1. This is accompanied by an increase in the intra-ovarian level of '17 β-estradiol and inhibin B.

    Full Text Available Background: Polycystic ovary syndrome (PCOS, the most common endocrinopathy in women of reproductive age, is characterized by polycystic ovaries, chronic anovulation, hyperandrogenism and insulin resistance. Despite the high prevalence of hyperandrogenemia, a definitive endocrine marker for PCOS has so far not been identified. Circulating miRNAs have recently been shown to serve as diagnostic/prognostic biomarkers in patients with cancers. Our current study focused on the altered expression of serum miRNAs and their correlation with PCOS. Method and Results: We systematically used the TaqMan Low Density Array followed by individual quantitative reverse transcription polymerase chain reaction assays to identify and validate the expression of serum miRNAs of PCOS patients. The expression levels of three miRNAs (miR-222, miR-146a and miR-30c were significantly increased in PCOS patients with respect to the controls in our discovery evaluation and followed validation. The area under the receiver operating characteristic (ROC curve (AUC is 0.799, 0.706, and 0.688, respectively. The combination of the three miRNAs using multiple logistic regression analysis showed a larger AUC (0.852 that was more efficient for the diagnosis of PCOS. In addition, logistic binary regression analyses show miR-222 is positively associated with serum insulin, while miR-146a is negatively associated with serum testosterone. Furthermore, bioinformatics analysis indicated that the predicted targets function of the three miRNAs mainly involved in the metastasis, cell cycle, apoptosis and endocrine. Conclusion: Serum miRNAs are differentially expressed between PCOS patients and controls. We identified and validated a class of three serum miRNAs that could act as novel non-invasive biomarkers for diagnosis of PCOS. These miRNAs may be involved in the pathogenesis of PCOS.

    Polycystic ovarian syndrome (PCOS) is the most frequent female endocrine disorder that affects 5-10% of women. PCOS is characterized by hyperandrogenism, oligo-/anovulation, and polycystic ovaries. The aim of the present research is to evaluate the expression of steroidogenic acute regulatory protein (StAR) and aromatase (CYP19) mRNA in the ovaries of an estradiol valerate (EV)-induced PCOS rat model, and the effect of treadmill and running wheel (voluntary) exercise on these parameters. In this experimental study, we divided adult female Wistar rats that weighed approximately 220 ± 20 g initially into control (n=10) and PCOS (n=30). Subsequently, PCOS group were divided to PCOS, PCOS with treadmill exercise (P-ExT), and PCOS with running wheel exercise (P-ExR) groups (n=10 per group). The expressions of StAR and CYP19 mRNA in the ovaries were determined by quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR). Data were analyzed by one-way ANOVA using SPSS software, version 16. The data were assessed at α=0.05. There was significantly lower mRNA expression of CYP19 in the EV-induced PCOS, running wheel and treadmill exercise rats compared to the control group (PStAR in the ovaries of the PCOS group indicated an increasing trend compared to the control group, however this was not statistically significant (P=0.810). We observed that 8 weeks of running wheel and treadmill exercises could not statistically decrease StAR mRNA expression compared to the PCOS group (P=0.632). EV-induced PCOS in rats decreased CYP19 mRNA expression, but had no effect on StAR mRNA expression. We demonstrated that running wheel and moderate treadmill exercise could not modify CYP19 and StAR mRNA expressions. Copyright© by Royan Institute. All rights reserved.

    Polycystic ovarian syndrome (PCOS), one of the leading causes of infertility seen in women, is characterized by anovulation and hyperandrogenism, resulting in ovarian dysfunction. In addition, associations of several metabolic complications like insulin resistance, obesity, dyslipidemia and psychological co-morbidities are well known in PCOS. One of the major factors influencing mood and the emotional state of mind is neurotransmitters. Also, these neurotransmitters are very crucial for GnRH release. Hence, the current study investigates the status of neurotransmitters in PCOS. A PCOS rat model was developed using testosterone. Twenty-one-day-old rats were subcutaneously injected with 10 mg/kg body weight of testosterone propionate (TP) for 35 days. The animals were validated for PCOS characteristics by monitoring estrus cyclicity, serum testosterone and estradiol levels and by histological examination of ovarian sections. Neurotransmitter estimation was carried out using fluorometric and spectrophotometric methods. TP-treated animals demonstrated increased serum testosterone levels with unaltered estradiol content, disturbed estrus cyclicity and many peripheral cysts in the ovary compared to control rats mimicking human PCOS. Norepinephrine (NE), dopamine, serotonin, γ-amino butyric acid (GABA) and epinephrine levels were significantly low in TP-induced PCOS rats compared to control ones, whereas the activity of acetylcholinesterase in the PCOS brain was markedly elevated. Neurotransmitter alteration could be one of the reasons for disturbed gonadotropin-releasing hormone (GnRH) release, consequently directing the ovarian dysfunction in PCOS. Also, decrease in neurotransmitters, mainly NE, serotonin and dopamine (DA) attributes to mood disorders like depression and anxiety in PCOS.

    Sheep are seasonal breeders, but a lower seasonality has been reported for sheep breeds from the Mediterranean countries enabling spring matings. To further substantiate this, the present study compared seasonal variation in oestrus behaviour and ovulation in two Greek breeds (Chios and Serres) maintained in the same environment. In 27 adult ewes of each breed, oestrus behaviour, the occurrence of ovulation and ovulation rate were monitored during 2 successive years by daily inspection by rams, weekly progesterone assay in circulating blood plasma and monthly ovarian laparoscopy. The periods of anoestrus (109 +/- 8 (wk) vs 178 +/- 5 d) and anovulation (63 +/- 8 vs 149 +/- 6 d) were significantly shorter (P duration of oestrus was also longer in Chios ewes (1.8 +/- 0.05 vs 1.5 +/- 0.06 d; P = 0.002). There were significant correlations between the duration of anovulatory periods of the 2 successive years in Chios (r = 0.43) but not Serres ewes. Ovulation rate was positively related to the onset of the sexual season in Serres but not in Chios ewes. The present data suggest that: i) the efficiency of Serres but not in Chios ewes. The present data suggest that: i) the efficiency of spring mating in these breeds is suboptimal since it is a period when the percentage of ewes exhibiting oestrus and ovulation as well as ovulation rate are limited, ii) owing to the large variation in seasonality within Chios ewes and to the good between year correlation in features of seasonality, selection against seasonality in Chios ewes could be worthwhile.

    Polycystic ovarian syndrome (PCOS) is a low-grade inflammatory disease characterized by hyperandrogenemia, hirsutism, chronic anovulation and vascular disorder. Interleukin-6 (IL-6), cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) are triggered by inflammatory stimuli and lead to angiogenesis and pathogenesis of the ovary. Honeybee venom (HBV) contains an array of biologically active components possessing various pharmaceutical properties. This study was designed to assess the possibility of HBV application as an anti-inflammatory therapeutic agent to suppress levels of the main inflammatory mediators IL-6, COX-2 and VEGF.To induce PCOS, 1 mg of estradiol valerate (EV) per 100 g of body weight was subcutaneously (SC) injected into eight-week-old rats. After 60 days, 0.5 mg/kg of HBV was administered Intraperitoneal (IP) for 14 consecutive days, and the results of PCOS treatment were investigated. Rats were then anesthetized with CO2, and the ovaries were surgically removed. Serum IL-6 was detected by the ELISA kit. Immunoexpression of COX-2 and VEGF were examined in three groups: EV-induced PCOS, HBV-treated PCOS and control animals. Thickness of theca layer, number and diameter of cysts and levels of IL-6 significantly decreased in HBV group relative to PCOS group. The immunohistochemical analysis showed an increase in COX-2 and VEGF expression in PCOS group whereas HBV-treated rats presented weak and irregular immunostaining. Our results suggest that the beneficial effect of HBV may be mediated through its inhibitory effect on serum IL-6 level and ovarian COX-2 and VEGF expression.

    Full Text Available Background Polycystic ovary syndrome (PCOS is a common but complex endocrine disorder and is the major cause of anovulation and consequent subfertility. In this study the effect of grape seed extract (GSE on triglyceride (TG, total cholesterol (TC, highdensity lipoprotein-cholestrol (HDL-C, low-density lipoprotein-cholestrol (LDL-C and interleukin-6 (IL-6 in PCOS Wistar rats were assessed. Materials and Methods In this experimental study, 84 adult female Wistar rats were divided into 7 groups (n=12 including control (intact, Sham (estradiol valerate solvent injection, control PCOS and 4 experimental PCOS groups. To induce the syndrome, a single subcutaneous injection of 2 mg estradiol valerate was applied. In experimental groups, PCOS rats were treated with different doses of 50, 75, 100 and 200 mg/kg body weight (BW GSE by intraperitoneal injection for 10 consecutive days. After harvesting blood serum, TG was measured by Glycerol-3-phosphate Oxidase-Peoxidase (GPO- PAP, TC by Cholesterol Oxidase-Peroxidase (CHOD-PAP, and HDL-C by sedimentation method, LDL-C by Friedwald calculation and IL-6 by ELISA method. The serum values of each parameter were analyzed using one-way ANOVA at P≤0.05. Results In all experimental groups significant decrease of visceral fat was obvious as compared with control PCOS group. LDL-C, TC and IL-6 levels in experimental groups, particularly at dose of 50 mg/kg of GSE, were significantly decreased as compared with PCOS group. However, HDL-C levels were not significantly changed. Conclusion : According to the findings of this study, it can be concluded that GSE with its effects on serum TC, LDL-C and IL-6 could reduce the effects of dyslipidemia and inflammation in PCOS rats and improve systemic symptoms of PCOS.

    To assess the capacity of the postcoital test (PCT) to predict pregnancy in WHO II anovulatory women who are ovulatory on clomiphene citrate (CC). In these women, an abnormal PCT result could be associated with lower pregnancy chances, but this has never been proven or refuted. Prospective cohort study was performed between December 2009 and September 2012 for all women who started ovulation induction with CC in one university clinic and two teaching hospitals in the Netherlands. A PCT was performed in one of the first three ovulatory cycles. Ovulation induction with CC was continued for at least six cycles. The PCT was judged to be positive if at least one progressive motile spermatozo was seen in one of five high power fields at 400× magnification. The primary outcome was time to ongoing pregnancy, within six ovulatory cycles. In 152 women the PCT was performed. 135 women had a reliable, well-timed PCT. The ongoing pregnancy rate was 44/107 (41%) for a positive and 10/28 (36%) for a negative PCT. The hazard rate for ongoing pregnancy was 1.3 (95% CI 0.64-2.5) for a positive versus a negative PCT. Thirty five of 77 (46%) women with clear mucus had an ongoing pregnancy versus 12 of 45 (27%) women in whom the mucus was not clear (HR 2.0; 95% CI 1.02-3.84, p=0.04). The present study suggests that the outcome of the postcoital test in women with WHO-II anovulation that undergo ovulation induction with CC does not have a large effect on ongoing pregnancy chances over time.

    Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism (H), oligo-anovulation (O) and / or polycystic ovaries (P). There is currently little information on perinatal complications. to investigate obstetric and neonatal characteristics of women with PCOS in our population. we studied 87 pregnant women with PCOS (categorized in four phenotypes according Rotterdam Consensus: A (H + O + P) n = 53; B (H + O) n = 9; C (H + P) n = 16 and D (O + P) n = 9) and 96 without PCOS (control). We analyzed clinical and biochemical features (age, anthropometry hirsutism, acanthosis nigricans, OGTT, insulin, lipid profile, androgen and gonadotropins) during preconception, (weight gain, blood pressure, OGTT) through gestation and occurrence of perinatal complications. we found no differences in age (29.4 ± 4 and 28.7 ± 5 years) and body mass index (28.2 ± 6 and 27.8 ± 6 kg / m2) in both groups; while patients with PCOS had higher waist circumference, blood pressure and acanthosis nigricans versus control. Despite similar weight gain, patients with PCOS had higher percentage of perinatal complications. In the A phenotype RR for perinatal adverse outcomes was 2.37 (95%CI: 1.67-3.36, p <0.001). The HOMA-IR index preconception and fasting glucose during pregnancy were the predictors for these complications (p=0.01). patients with PCOS have a higher risk for complications during pregnancy and newborns more frequently have low weight or macrosomy. A careful history can recognize patients with higher perinatal risk to develop complications.

    Full Text Available Abstract Background The polycystic ovary syndrome (PCOS affects approximately 6-10% of women of reproductive age and is characterized by chronic anovulation and hyperandrogenism. However, a comprehensive understanding of the mechanisms that dictate androgen overproduction is lacking, which may account for inconsistencies between measures of androgen excess and clinical presentation in individual cases. Methods A rat model of PCOS was established by injecting dehydroepiandrosterone sulfoconjugate (DHEAS into pregnant females. Rats were administered with DHEAS (60 mg/kg/d subcutaneously (s.c. for all 20 days of pregnancy (Group A, or for the first 10 days (Group B, or from day 11 to day 20 (Group C. Controls were administered with injection oil (0.2 ml/day s.c. throughout pregnancy (Group D. The litter rate, abortion rate, and offspring survival rate in each group were recorded. Serum androgen and estrogen were measured and the morphological features of the ovaries were examined by light and electron microscopy in the offspring of each group. Results We found that rats injected with DHEAS throughout pregnancy (group A lost fertility. Rats injected with DHEAS during early pregnancy (group B exhibited more serious aberrations in fertility than both Group C, in which rats were injected with DHEAS during late pregnancy (P  Conclusions Our results indicate that androgen excess during pregnancy can decrease rat fertility. Excess androgen at the early stage of pregnancy causes high reproductive toxicity, leading to abnormality of ovarian morphology and functions in female offspring.

    Full Text Available Polycystic ovary syndrome (PCOS is one of the most frequent endocrine disorders in women of reproductive age, characterized by the association of polycystic ovaries, hyperandrogenism and chronic anovulation. Excessive ovarian production of anti- mülerian hormone (AMH, secreted by the excess of growing follicles, is now considered an important feature of PCOS, with an increasing number of evidence in the last decade on the role of AMH in the pathogenesis of the syndrome. The aim of this study was to determine the sensitivity and specificity of AMH in the diagnosis of PCOS, as well as the association of AMH with other components of the syndrome. A cross-sectional study of clinical, hormonal and biochemical markers in 60 patients with PCOS and 30 controls was conducted. There was a statistically significant difference of AMH values between the groups, with an almost 5-fold increase in circulating AMH levels in women with PCOS compared with those without the syndrome. Positive significant correlation of AMH values with the duration of the menstrual cycle, as well as a significant correlation with testosterone levels and negative significant correlation with the levels of follicle stimulating hormone were observed. Measurement of serum AMH levels as a diagnostic modality of PCOS showed high sensitivity and specificity. Optimal specificity and sensitivity were achieved at the cut-off level of 5 ng/ml offering sensitivity of 82.76% and specificity of 88.89 % with a positive predictive value of 94.12%. This study showed that AMH could be used as an alternative diagnostic tool in PCOS patients.

    Full Text Available Introduction: Polycystic ovary syndrome (PCOS is one of the most common endocrine disorders in women. PCOS comprises a broad spectrum of anomalies, including hyperandrogenism, chronic anovulation, obesity, and infertility. Insulin resistance and its compensatory hyperinsulinemia play a key role in the pathogenicity of PCOS. This study compares the effects of 2 types of insulin sensitizer drugs, metformin and pioglitazone, on clinical, metabolic, and endocrine characteristics of women with PCOS. Methods: In this randomized clinical trial, 56 women with PCOS (ages 20–49 years were treated orally with either metformin (500 mg 3 times daily or pioglitazone (30 mg daily for 3 months. Clinical (body weight, blood pressure [BP], and body mass index and laboratory indices (fasting blood sugar [FBS], serum triglyceride [TG], cholesterol, low-density lipoprotein, high-density lipoprotein, insulin, testosterone, and dehydroepiandrosterone [DHEA] were measured before and after therapy. Data were analyzed by Chi-square and McNemar's tests. Results: Significant decreases were seen after treatment with metformin in extent of hair loss (P = 0.008, wrist circle (P = 0.011, weight (P = 0.047, diastolic BP (P = 0.023, and DHEA (P = 0.035. A significant decrease in TG was seen with pioglitazone treatment (P = 0.047. In both groups, significant decreases in acne, menstrual disturbance, FBS, and serum insulin were seen. Conclusion: There is a significant amelioration of endocrine and metabolic indices with pioglitazone in PCOS patients. Although we were not able to recommend one treatment regime over the other, pioglitazone offers a useful, alternate treatment in women with PCOS who are not able to tolerate metformin.

    2011-01-01

    Full Text Available Background: Polycystic ovary syndrome (PCOS is associated with approximately 75% of women who suffer from infertility due to anovulation. Additionally, around 20– 25% of anovulatory women with PCOS do not respond at all to clomiphene citrate and are considered to be “clomiphene– resistant”. Aromatase inhibitors have been suggested as an alternative treatment to clomiphene as the discrepancy between ovulation and pregnancy rates with clomiphene citrate has been attributed to its anti-estrogenic action and estrogen receptor depletion. Objective: The aim of this study is to compare results of Metformin-letrozole with Metformin-clomiphene citrate in clomiphene resistance PCOS patients undergoing IUI.Materials and Methods: In this single blind randomized trial, ovarian cycles were studied in 100 clomiphene- resistant patients with PCOS. The inclusion criteria were patients who received 150mg clomiphene citrate daily for 3 cycles and failed to become pregnant. The patients were matched for their age, body mass index (BMI, and infertility period. They were randomly allocated to a metformin-letrozole group (n=50 and a metformin-clomiphene citrate group (n=50. Chemical and clinical pregnancies were assessed after IUI. Abortion rates were determined in both groups. Results: Regarding pregnancy rate, there was no significant difference between the two groups. One miscarriage (2% occurred in the metformin-clomiphene citrate group, whereas none was seen in the metformin-letrozole group. Conclusion: There is no significant difference in pregnancy rate between clomiphene citrate and letrozole groups although it has been 2% in the former and 5% in the latter.

    Full Text Available Background: Polycystic ovarian syndrome (PCOS was first introduced by Leventhal and Steinin 1935. It has a wide range of manifestations such as hyperandrogenism, irregular menstruationand central body obesity. The lack of definite diagnostic criteria has made the diagnosis a difficulttask. Moreover, the disturbing aspects of the syndrome range from hirsutism in an adolescent girlto infertility in a young woman. Based on the Rotterdam 2003 Criteria, current diagnostic criteriamust include two of the following three symptoms:1. Either oligo-ovulation or anovulation,2. Clinical or laboratory manifestations of hyperandrogenism,3. Polycystic ovaries on sonographic examination (more than 12 follicles of less than 10 mm indiameter in each ovary.In this study, we have focused on the enrollment of a large sample size to assess the prevalence andclinical features of PCOS such that a wide range of basic information can be utilized for furtherinvestigations.Materials and Methods: This was a cross-sectional study with multi-stage random sampling.Subjects were selected from 15-18 years old girls from a number of high schools in Tehran. Afterinterview and clinical examination, those individuals with either menstrual irregularities, hirsutismor obesity were referred for further laboratory evaluations and abdominal sonography in order todiagnose PCOS and estimate its prevalence. We also aimed to assess the predominant features ofthis disorder among adolescents.Results: The overall prevalence of the syndrome was 3.42%. Out of the 1430 girls, 49 werediagnosed with PCOS.Conclusion: Despite its high prevalence, this syndrome has not been widely studied. Most of theconducted studies have enrolled small samples within a short time period. Thus, more accuratepolicy making in this regard can be achieved through definition of the prevalence of PCOS andaccurate estimation of its burden.

    Thousands of safety-related studies have been published on bisphenol A (BPA), an ubiquitous environmental pollutant with estrogenic activity and many other potential biological effects. In recent years, BPA exposure has been shown to cause anovulation and infertility through irreversible alteration of the hypothalamic-pituitary-gonadal axis in several organisms, including fish and mammals. Recently, the European Chemical Agency classified BPA as a "substance of very high concern" because of its endocrine-disrupting properties, which have serious effects on human health. Given the risk of exposure to BPA as a pollutant in the environment, food, and drinking water, the objective of our study was to assess the effects of this compound on the adeno-hypophysis by means of a histopathological and morphometric study of the gonadotroph cells. In addition, using quantitative real-time PCR (qRT-PCR) assays, we analyzed the changes in the expression of Cyp19b (an aromatase gene). Zebrafish were randomly distributed into five groups: a control group and 4 treated groups which were exposed to different BPA concentrations (1, 10, 100 and 1000 µg/L). The effects of the different doses on Cyp19b mRNA molecules followed a non-monotonic curve, with the 1 and 1000 µg/L doses causing dramatic decreases in the number of Cyp19b transcripts while the doses of 10 and 100 µg/L caused important increases. The consequences might be deregulation of gonadotropic hormones causing degeneration of gonadotropic cells, as observed in BPA treated animals. This is the first study in which the gonadotroph cells have been evaluated using histomorphological endpoints after BPA exposure in zebrafish. Copyright © 2018 Elsevier Inc. All rights reserved.

    Identifying cows in estrus remains a challenge on dairy cattle farms, and tools and technologies have been developed and used to complement or replace visual detection of estrus. Automated activity monitoring (AAM) systems and timed artificial insemination (TAI) are technologies available to dairy farmers, but many factors can influence their relative performance. The objective of the present study was to compare reproductive performance of cows managed with an AAM system combined with TAI, or with a TAI program (Double Ovsynch) for insemination before 88 DIM. From April 2014 to April 2015, 998 cows from 2 herds were randomly assigned either to be inseminated at 85 ± 3 DIM exclusively using the Double Ovsynch protocol for TAI, or to be inseminated based on estrus detection by AAM without hormonal intervention between 50 and 75 DIM; if no alarm was detected by 75 DIM, cows were inseminated following the single Ovsynch protocol (AAM + Ovsynch). The herds used different AAM systems. Parity, hyperketonemia at wk 1 and 2 postpartum (PP), purulent vaginal discharge at wk 5 PP, body condition score at wk 7 PP, and anovulation to wk 9 PP were recorded. These health indicators did not significantly differ between treatments, but did between herds. The effect of treatment on pregnancy at first insemination and by 88 DIM were assessed using logistic regression models. Time to pregnancy was assessed using survival analysis. Results are reported from intention-to-treat analyses. Treatment did not affect pregnancy at first insemination or pregnancy by 88 DIM, but we found significant interactions between treatment and herd for both outcomes. In herd 2, marginal mean pregnancy at first AI was greater with Double Ovsynch (38%) than AAM + Ovsynch (31%), but no difference was observed in herd 1 (Double Ovsynch = 31%; AAM + Ovsynch = 34%). By 88 DIM, a smaller proportion of cows in herd 1 were pregnant in Double Ovsynch (31%) than AAM + Ovsynch (49%), but there was no difference in

    Full Text Available The objective of the research was to study the indices of local immunity in relation to the hormonal state of the body in women with benign ovarian tumors and pre-existing cervical diseases. Materials and methods. The concentration of major gonadotropic and steroid hormones during the female ovarian and menstrual cycle, as well as individual local immunity factors of proinflammatory cytokines and secretory immunoglobulin A was studied in 40 patients with benign ovarian tumors and pre-existing cervical diseases. Results and discussion. In the second phase of the ovarian and menstrual cycle, a significant reduction (by 3.0 times in the concentration of progesterone and relative hypoestrogenism (by 1.5 times as compared to the control data were found. Anovulation was observed in 40.00% of cases and corpus luteum deficiency syndrome was diagnosed in 62.5% of women. The assessment of secretory immunoglobulin A concentration allowed us to note (along with the hypersecretion of proinflammatory cytokines an increase in this marker in half of the examined women in the presence of chronic cervicitis and vaginitis, candidiasis and viral lesion - along with the activation of proinflammatory cytokine depression of secretory immunoglobulin A synthesis as compared to the control data. Conclusions. Local immunity changes in women with benign ovarian tumors and pre-existing cervical diseases are accompanied by abnormalities of the hormonal profile and the association of maladaptive changes in the system of local immunity manifested by fluctuations in the level of secretory immunoglobulin A during the secretory phase of the menstrual cycle and an increase in proinflammatory cytokine synthesis. The results of the conducted study allowed us to note a significant increase in the concentration of secretory immunoglobulin A along with the activation of proinflammatory cytokine synthesis in most women with benign ovarian tumors and pre-existing cervical diseases which

    Background Ovulatory menstrual cycles are essential for women’s fertility and needed to prevent bone loss. There is a medical/cultural expectation that clinically normal menstrual cycles are inevitably ovulatory. Currently within the general population it is unknown the proportion of regular, normal-length menstrual cycles that are ovulatory. Thus, the objective of this study was to determine the population point prevalence of ovulation in premenopausal, normally menstruating women. The null hypothesis was that such cycles are ovulatory. Methods This is a single-cycle, cross-sectional, population-based study—a sub-study of the HUNT3 health study in the semi-rural county (Nord Trøndelag) in mid-Norway. Participants included >3,700 spontaneously (no hormonal contraception) menstruating women, primarily Caucasian, ages 20–49.9 from that county. Participation rate was 51.9%. All reported the date previous flow started. A single, random serum progesterone level was considered ovulatory if ≥9.54 nmol/L on cycle days 14 to -3 days before usual cycle length (CL). Results Ovulation was assessed in 3,168 women mean age 41.7 (interquartile range, [IQR] 36.8 to 45.5), cycle length 28 days (d) (IQR 28 to 28) and body mass index (BMI) 26.3 kg/m2 (95% CI 26.1 to 26.4). Parity was 95.6%, 30% smoked, 61.3% exercised regularly and 18% were obese. 1,545 women with a serum progesterone level on cycle days 14 to -3 were presumed to be in the luteal phase. Of these, 63.3% of women had an ovulatory cycle (n = 978) and 37% (n = 567) were anovulatory. Women with/ without ovulation did not differ in age, BMI, cycle day, menarche age, cigarette use, physical activity, % obesity or self-reported health. There were minimal differences in parity (96.7% vs. 94.5%, P = 0.04) and major differences in progesterone level (24.5 vs. 3.8 nmol/L, P = 0.001). Conclusion Anovulation in a random population occurs in over a third of clinically normal menstrual cycles. PMID:26291617

    Full Text Available Background: Polycystic ovarian syndrome (PCOS is the most frequent female endocrine disorder that affects 5-10% of women. PCOS is characterized by hyperandrogenism, oligo-/anovulation, and polycystic ovaries. The aim of the present research is to evaluate the expression of steroidogenic acute regulatory protein (StAR and aromatase (CYP19 mRNA in the ovaries of an estradiol valerate (EV-induced PCOS rat model, and the effect of treadmill and running wheel (voluntary exercise on these parameters. Materials and Methods: In this experimental study, we divided adult female Wistar rats that weighed approximately 220 ± 20 g initially into control (n=10 and PCOS (n=30. Subsequently, PCOS group were divided to PCOS, PCOS with treadmill exercise (P-ExT, and PCOS with running wheel exercise (P-ExR groups (n=10 per group. The expressions of StAR and CYP19 mRNA in the ovaries were determined by quantitative real-time reverse transcriptase polymerase chain reaction (qRT-PCR. Data were analyzed by one-way ANOVA using SPSS software, version 16. The data were assessed at α=0.05. Results: There was significantly lower mRNA expression of CYP19 in the EV-induced PCOS, running wheel and treadmill exercise rats compared to the control group (P<0.001. Treadmill exercise (P=0.972 and running wheel exercise (P=0.839 had no significant effects on CYP19 mRNA expression compared to the PCOS group. mRNA expression of StAR in the ovaries of the PCOS group indicated an increasing trend compared to the control group, however this was not statistically significant (P=0.810. We observed that 8 weeks of running wheel and treadmill exercises could not statistically decrease StAR mRNA expression compared to the PCOS group (P=0.632. Conclusion: EV-induced PCOS in rats decreased CYP19 mRNA expression, but had no effect on StAR mRNA expression. We demonstrated that running wheel and moderate treadmill exercise could not modify CYP19 and StAR mRNA expressions.

    The purpose of this study was to evaluate the reproductive status and clarify the reproductive physiology of captive Sichuan golden monkeys. The concentrations of urinary estradiol-3-glucuronide (E 2 G) and pregnanediol-glucuronide (PdG) or fecal estradiol-17β (E 2 ) and PdG in two females, and fecal testosterone concentrations in a male, were measured continuously using enzyme immunoassays. On the basis of these hormone profiles, the follicular phase, luteal phase, and ovarian cycle were calculated to be 14.7 ± 4.8, 10.4 ± 2.8, and 25.1 ± 3.3 days, respectively. The first ovulation (puberty) in a female monkey was observed at 5.1 years old, and the first pregnancy was diagnosed at 6.4 years old. For the first 2 months of pregnancy (204 days), fecal E 2 and PdG maintained constant high values and then increased until parturition. These profiles were similar to urinary E 2 G and PdG changes. During the last trimester of a twin pregnancy, fecal PdG was up to approximately three times higher compared with a single pregnancy. Therefore, fecal PdG levels in late pregnancy may be effective for the detection of a twin pregnancy. The first postpartum ovulation occurred 66 (fetal death and artificial rearing), 143 (fetal death), and 189 (natural suckling) days after parturition. The anovulation period of the natural suckling case was longer than the others. Conception and postpartum ovulation were detected between September and January. Fecal testosterone levels of the male were correlated with the fecal E 2 level of the nonpregnancy period in exhibited together female. Our results reported that urinary (E 2 G and PdG) and fecal (E 2 and PdG) hormone measurement is effective for monitoring the reproductive status, thereby expanding knowledge of the reproductive endocrinology of this endangered species.

    We studied a group of obese hyperandrogenic amenorrheic women to determine the effects of weight loss on anthropometry, hormonal status, menstrual cycles, ovulation, and fertility. Fourteen women had polycystic ovaries, two the hyperandrogenism-insulin resistance-acanthosis nigricans syndrome, one hirsutism of adrenal origin, and three idiopathic chronic anovulation. The duration of amenorrhea before the study ranged from 3-17 months [mean, 8.6 +/- 4.5 (+/- SD)]. All women ate a hypocaloric diet for a period of 8.0 +/- 2.4 months. Weight loss ranged from 4.8 to 15.2 kg (mean, 9.7 +/- 3.1 kg; 1.35 +/- 0.56 kg/month) and the waist to hip ratio, which was used as a measurement of body fat distribution, decreased from 0.86 +/- 0.1 to 0.81 +/- 0.06 (P less than 0.0001). The women's mean plasma testosterone and LH concentrations decreased significantly (P less than 0.001 and P less than 0.005, respectively). A significant positive correlation was found between the decreases in plasma testosterone levels and the decreases in glucose-stimulated insulin levels. Moreover, the decreases in the waist to hip ratio correlated positively with the decreases in glucose-stimulated insulin levels and inversely with the decreases in plasma 17 beta-estradiol. No relationships were found between weight loss and the changes in plasma insulin, steroid, and gonadotropin concentrations. The responsiveness to the weight reduction program was evaluated by comparing the number of menstrual cycles during the study period with the number reported before it. Eight women had significantly improved menstrual cyclicity (responders), while 12 did not (nonresponders). The clinical characteristics and hormone values were similar in responder and nonresponder women. In the group as a whole, 33% of the menstrual cycles during the study were ovulatory, and 4 pregnancies occurred. Hirsutism improved significantly in more than half of the women, as did acanthosis nigricans when present. We conclude that

    Ketosis-prone diabetes (KPD) is heterogeneous. Longitudinal follow-up revealed that patients with "A-β+" KPD (absent autoantibodies and preserved β-cell function) segregated into 2 subgroups with distinct evolution of β-cell function and glycemic control. Generalized linear analysis demonstrated that the variable that most significantly differentiated them was presence of a clinically evident precipitating event for the index diabetic ketoacidosis (DKA). Hence, we performed a comprehensive analysis of A-β+ KPD patients presenting with "provoked" compared with "unprovoked" DKA. Clinical, biochemical, and β-cell functional characteristics were compared between provoked and unprovoked A-β+ KPD patients followed prospectively for 1 to 8 years. Human leukocyte antigen class II allele frequencies were compared between these 2 groups and population controls. Unprovoked A-β+ KPD patients (n = 83) had greater body mass index, male preponderance, higher frequency of women with oligo-/anovulation, more frequent African American ethnicity, and less frequent family history of diabetes than provoked A-β+ KPD patients (n = 64). The provoked group had higher frequencies of the human leukocyte antigen class II type 1 diabetes mellitus susceptibility alleles DQB1*0302 (than the unprovoked group or population controls) and DRB1*04 (than the unprovoked group), whereas the unprovoked group had a higher frequency of the protective allele DQB1*0602. β-Cell secretory reserve and glycemic control improved progressively in the unprovoked group but declined in the provoked group. The differences persisted in comparisons restricted to patients with new-onset diabetes. "Unprovoked" A-β+ KPD is a distinct syndrome characterized by reversible β-cell dysfunction with male predominance and increased frequency of DQB1*0602, whereas "provoked" A-β+ KPD is characterized by progressive loss of β-cell reserve and increased frequency of DQB1*0302 and DRB1*04. Unprovoked DKA predicts long

    Do naturally occurring, hyperandrogenic (≥1 SD of population mean testosterone, T) female rhesus monkeys exhibit traits typical of women with polycystic ovary syndrome (PCOS)? Hyperandrogenic female monkeys exhibited significantly increased serum levels of androstenedione (A4), 17-hydroxyprogesterone (17-OHP), estradiol (E2), LH, antimullerian hormone (AMH), cortisol, 11-deoxycortisol and corticosterone, as well as increased uterine endometrial thickness and evidence of reduced fertility, all traits associated with PCOS. Progress in treating women with PCOS is limited by incomplete knowledge of its pathogenesis and the absence of naturally occurring PCOS in animal models. A female macaque monkey, however, with naturally occurring hyperandrogenism, anovulation and polyfollicular ovaries, accompanied by insulin resistance, increased adiposity and endometrial hyperplasia, suggests naturally occurring origins for PCOS in nonhuman primates. As part of a larger study, circulating serum concentrations of selected pituitary, ovarian and adrenal hormones, together with fasted insulin and glucose levels, were determined in a single, morning blood sample obtained from 120 apparently healthy, ovary-intact, adult female rhesus monkeys (Macaca mulatta) while not pregnant or nursing. The monkeys were then sedated for somatometric and ultrasonographic measurements. Female monkeys were of prime reproductive age (7.2 ± 0.1 years, mean ± SEM) and represented a typical spectrum of adult body weight (7.4 ± 0.2 kg; maximum 12.5, minimum 4.6 kg). Females were defined as having normal (n = 99) or high T levels (n = 21; ≥1 SD above the overall mean, 0.31 ng/ml). Electronic health records provided menstrual and fecundity histories. Steroid hormones were determined by tandem LC-MS-MS; AMH was measured by enzymeimmunoassay; LH, FSH and insulin were determined by radioimmunoassay; and glucose was read by glucose meter. Most analyses were limited to 80 females (60 normal T, 20 high T) in

    Full Text Available Abstract Background Under-carboxylated osteocalcin (ucOC, the precursor substrate of bone biomarker OC is a potent regulator of energy metabolism by promoting insulin production and adiponectin synthesis and decreasing fat stores. The aim of the present study was to point out the potential role of ucOC in the physiopathology of polycystic ovary syndrome (PCOS, a common disorder defined by the constellation of anovulation, insulinresistance, hyperinsulinemia, obesity and androgen excess. Methods In this prospective case–control investigation, 78 young premenopausal women, i.e. 52 PCOS patients and 26 age- and body mass index (BMI-matched healthy controls, were successively enrolled. Recruitment of PCOS patients was performed according to Androgen Excess-Polycystic Ovary Syndrome (AE-PCOS Society 2006 criteria. All study participants were subjected to clinical examination, whole-body composition assessment and measurements of serum ucOC, OC (1-49, glucose and lipids, insulin, total testosterone (TT, estradiol, sex-hormone binding globulin (SHBG, high-sensitivity C-reactive protein (Hs-CRP and β-CrossLaps. Results BMI-stratified multivariate analysis revealed significantly higher ucOC levels in PCOS vs. controls in lean (p = 0.001 but not overweight and obese study participants (p = 0.456. Notably, a positive correlation between ucOC and TT (p = 0.018, calculated free testosterone (cFT, p = 0.028 and serum insulin (p = 0.036, respectively, was found to be confined to the lean analysis subgroup. Furthermore, in stepwise multiple regression models, β-CrossLaps and cFT were able to predict 46.71% of serum ucOC variability. (1-43/49OC failed to be significantly associated to any PCOS trait. Conclusions Circulating ucOC concentration is related to key endocrine PCOS characteristics in a weight-dependent manner. Within the bone-pancreas loop, high ucOC may favor insulin release in lean hyperandrogenic women to compensate for

    Polycystic ovary syndrome (PCOS) is a prevalent, complex endocrine disorder characterised by polycystic ovaries, chronic anovulation and hyperandrogenism leading to symptoms of irregular menstrual cycles, hirsutism, acne and infertility. Evidence based medical management emphasises a multidisciplinary approach for PCOS, as conventional pharmaceutical treatment addresses single symptoms, may be contra-indicated, is often associated with side effects and not effective in some cases. In addition women with PCOS have expressed a strong desire for alternative treatments. This review examines the reproductive endocrine effects in PCOS for an alternative treatment, herbal medicine. The aim of this review was to identify consistent evidence from both pre-clinical and clinical research, to add to the evidence base for herbal medicine in PCOS (and associated oligo/amenorrhoea and hyperandrogenism) and to inform herbal selection in the provision clinical care for these common conditions. We undertook two searches of the scientific literature. The first search sought pre-clinical studies which explained the reproductive endocrine effects of whole herbal extracts in oligo/amenorrhoea, hyperandrogenism and PCOS. Herbal medicines from the first search informed key words for the second search. The second search sought clinical studies, which corroborated laboratory findings. Subjects included women with PCOS, menstrual irregularities and hyperandrogenism. A total of 33 studies were included in this review. Eighteen pre-clinical studies reported mechanisms of effect and fifteen clinical studies corroborated pre-clinical findings, including eight randomised controlled trials, and 762 women with menstrual irregularities, hyperandrogenism and/or PCOS. Interventions included herbal extracts of Vitex agnus-castus, Cimicifuga racemosa, Tribulus terrestris, Glycyrrhiza spp., Paeonia lactiflora and Cinnamomum cassia. Endocrine outcomes included reduced luteinising hormone (LH), prolactin

    Polycystic ovary syndrome (PCOS) is a condition of androgen excess and chronic anovulation frequently associated with insulin resistance. We combined a nontargeted and targeted metabolomics approach to identify pathways and metabolites that distinguished PCOS from metabolic syndrome (MetS). Twenty obese women with PCOS were compared with 18 obese women without PCOS. Both groups met criteria for MetS but could not have diabetes mellitus or take medications that treat PCOS or affect lipids or insulin sensitivity. Insulin sensitivity was derived from the frequently sampled intravenous glucose tolerance test. A nontargeted metabolomics approach was performed on fasting plasma samples to identify differentially expressed metabolites, which were further evaluated by principal component and pathway enrichment analysis. Quantitative targeted metabolomics was then applied on candidate metabolites. Measured metabolites were tested for associations with PCOS and clinical variables by logistic and linear regression analyses. This multiethnic, obese sample was matched by age (PCOS, 37±6; MetS, 40±6years) and body mass index (BMI) (PCOS, 34.6±5.1; MetS, 33.7±5.2kg/m 2 ). Principal component analysis of the nontargeted metabolomics data showed distinct group separation of PCOS from MetS controls. From the subset of 385 differentially expressed metabolites, 22% were identified by accurate mass, resulting in 19 canonical pathways significantly altered in PCOS, including amino acid, lipid, steroid, carbohydrate, and vitamin D metabolism. Targeted metabolomics identified many essential amino acids, including branched-chain amino acids (BCAA) that were elevated in PCOS compared with MetS. PCOS was most associated with BCAA (P=.02), essential amino acids (P=.03), the essential amino acid lysine (P=.02), and the lysine metabolite α-aminoadipic acid (P=.02) in models adjusted for surrogate variables representing technical variation in metabolites. No significant differences between

    Full Text Available Objective Ketoconazole (KCZ is a known inhibitor of steroidogenic P450 enzymes in the adrenal cortex and the gonads. Previous studies examined the potential clinical use of KCZ for attenuation of ovarian response to gonadotropin treatments. This study aimed to use the superovuating rat model to explore the effect of KCZ on ovarian steroidogenesis, follicular function, and development toward ovulation. Methods Prepubertal rats were treated with equine chorionic gonadotropin (eCG/human CG (hCG resulting in multiple follicular development and ovulation. The effect of KCZ on this model was examined by administration of KCZ-gel formula and subsequent analyses of ovarian steroidogenesis, rate of ovulation, morphometric assessments of follicular parameters, and cell-specific steroidogenic maturation of the treated ovaries. Results When applied shortly before gonadotropin stimulation, KCZ markedly reduced ovarian progesterone, androstenedione, and estradiol levels down to 18.7, 36.5, and 19.0%, respectively ( P < 0.001. A single KCZ-gel administration of 6, 12, and 24 mg/rat resulted in reduction of ovulated ova/ovary down to 8.6 ± 4.9, 5.1 ± 4.3, and 2.4 ± 3.2, respectively, as compared to 13.6 ± 4.4 ova found in the oviduct of control-gel-injected animals ( P < 0.001. An alternative protocol made use of small KCZ doses injected in non-gel formula (5 mg/dose/8 hours, commenced with the eCG administration and terminated 24 hours later; this treatment readily inhibited the ovulation rates to 6.6 ± 6.6 as compared to 16.5 ± 4.1 ova/ovary in the control group ( P < 0.01. By contrast, KCZ failed to inhibit ovulation if administered 24 hours after eCG injection. Anovulation by KCZ resulted from arrest of follicular development at the stage of 800-840 μm Graafian follicles as compared to 920 μm of peri-ovulatory follicles (OFs observed in the control group, P = 0.029. In addition, absence of CYP11A1 expression was evident in the granulosa cell layers

    Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive-aged women that manifests itself with a variety of features. For this reason, three different diagnostic criteria have been introduced. For adults, the National Institutes of Health Conference (NIH) criteria, which consists of hyperandrogenism and oligo-anovulation, is the most widely used. Symptoms of PCOS usually start with puberty and may overlap with normal pubertal development. Hormonal fluctuations during this period make the diagnosis of PCOS more difficult. Until now, there is no validated diagnostic criteria for PCOS in adolescents. Although menstrual disorders and cosmetic problems are the most common complaints of adolescents with PCOS, patients should also be evaluated for the potential risk for insulin resistance, obesity, subclinical atherosclerosis, diabetes, metabolic syndrome and cardiovascular disease. Obesity is the most prominent predictor of metabolic syndrome. As the incidence of obesity is increasing both in childhood and adolescence, governments will be faced with a social and economic burden in the future. Adolescents with PCOS are more obese than normal adolescents and have an increased risk of metabolic syndrome. It is suggested that abdominal adiposity increases the risk of metabolic syndrome by inducing various cytokine secretions. Although there is no consensus on metabolic syndrome criteria in the adolescent period, International Diabetes Federation (IDF) criteria may be used for children older than 10 years. Various clinical and metabolic markers are investigated for the prediction of metabolic syndrome in the literature. Waist circumference, serum triglycerides and androgens are the suspected predictors of metabolic syndrome. The prevention of abdominal adiposity and the early diagnosis of PCOS in adolescence should be the main target for the prevention of metabolic syndrome.

    Polycystic ovary syndrome (PCOS) affects 5-10% of women of childbearing age and manifests itself through oligomenorrhea, anovulation, hirsutism, micro-polycystic ovaries. Insulin resistance is a characteristic of PCOS patients and is more pronounced in obese patients. Insulin resistance and consequent hyperinsulinemia are related to many aspects of the syndrome such as hyperandrogenism, reproductive disorders, acne and hirsutism. In the long-term it may increase the risk of cardiovascular disease and negatively affect lipid profile and blood pressure. Changes in lifestyle and diet can partially improve these aspects. The use of insulin-sensitizing drugs such as metformin often normalises the menstrual cycle, improving hyperandrogenism and, subsequently, the response to ovulation induction therapies. New molecules have recently been marketed, that produce the same results, but without the side-effects. One of these is myo-inositol, a new insulin-sensitizing molecule which has been successfully administered to women suffering from PCOS. Associations between inositol and other compounds that can increase the therapeutic effect have been proposed. Of these, we found to be interesting the association with monacolin K, a natural statin that reduces cholesterol levels starting point of the synthesis of steroids, including androgens, and lipoic acid, known for its anti-inflammatory, antioxidant and insulin-sensitizing activity. We decided to assess the efficacy of the product. We recruited 30 women aged between 24 and 32 years suffering from PCOS with insulin resistance, HOMA index>2.5 and no other endocrine diseases. The following were assessed: Body Mass Index (BMI), characteristics of menstrual cycles, lipid profile (total cholesterol, and HDL), androgens (total testosterone and androstenedione). The patients were also assessed for the degree of hirsutism using the Ferriman-Gallwey Score>8. The subjects were divided into two groups: Group A, treated with an association

    suppresses endometrial mitotic activity and its proliferation. Most epidemiologic studies show that oral contraceptives reduce the risk of endometrial cancer and that this protective effect exists many years after the discontinuation of medication. It has been long known that the oral contraceptive use causes protective anovulation and reduces the risk of ovarian cancer. This powerful reduction is the best demonstrated major benefit of oral contraception. This protection is especially observed in nulliparous and seems to persist for many years after the discontinuation of medication.

In this study, we used a combination of letrozole and clomiphene in patients resistant to both drugs individually, and studied the effects of this combination in ovulation and pregnancy in resistant PCOS patients. Methods: The study population included infertile couples diagnosed as PCOS in the wife. The women used clomiphene for at least six cycles in order to ovulate after failure to form the dominant follicle, and were then put on letrozole for four cycles. Patients who were unable to form the dominant follicle were enrolled on letrozole and clomiphene combination therapy. Results: One hundred enrolled patients underwent 257 cycles of a combination of letrozole and clomiphene, in which 213 were able to form the dominant follicle (82.9% and 44 were unable to do so (17.1%. The number of mature follicles was 2.3±1.1. The mean endometrial thickness in patients on the day of human chorionic gonadotropin administration was 8.17±1.3 mm. The pregnancy rate was 42%. Conclusion: According to the results of this study, it can be proposed that in PCOS patients resistant to clomiphene and letrozole used as single agents, a combination of the two drugs can be administered before using more aggressive treatment that may have severe complications or surgery. This combination may also be used as a first-line therapy to induce ovulation in severe cases of PCOS in order to

    In order to develop a medical alternative to surgical ovarian diathermy (OD) in polycystic ovary syndrome (PCOS) more mechanistic information is required about OD. We therefore studied the cellular, molecular and vascular effects of diathermy on the ovary using an established ovine model of PCOS. Pregnant sheep were treated twice weekly with testosterone propionate (100 mg) from day 30-100 gestation. Their female offspring (n = 12) were studied during their second breeding season when the PCOS-like phenotype, with anovulation, is fully manifest. In one group (n = 4) one ovary underwent diathermy and it was collected and compared to the contralateral ovary after 24 hours. In another group a treatment PCOS cohort underwent diathermy (n = 4) and the ovaries were collected and compared to the control PCOS cohort (n = 4) after 5 weeks. Ovarian vascular indices were measured using contrast-enhanced ultrasound and colour Doppler before, immediately after, 24 hours and five weeks after diathermy. Antral follicles were assessed by immunohistochemistry and ovarian stromal gene expression by quantitative RT-PCR 24 hours and 5 weeks after diathermy. Diathermy increased follicular atresia (P<0.05) and reduced antral follicle numbers after 5 weeks (P<0.05). There was an increase in stromal CCL2 expression 24 hours after diathermy (P<0.01) but no alteration in inflammatory indices at 5 weeks. Immediately after diathermy there was increased microbubble transit time in the ovarian microvasculature (P = 0.05) but this was not seen at 24 hours. However 24 hours after diathermy there was a reduction in the stromal Doppler blood flow signal (P<0.05) and an increased ovarian resistance index (P<0.05) both of which persisted at 5 weeks (P<0.01; P<0.05). In the ovine model of PCOS, OD causes a sustained reduction in ovarian stromal blood flow with an increased ovarian artery resistance index associated with atresia of antral follicles.

    What is the prevalence of polycystic ovary syndrome (PCOS) in Han Chinese women from different communities? The prevalence of PCOS in Chinese women aged 19-45 years is 5.6%. The prevalence of PCOS is reported to range from 5 to 10% but to the best of our knowledge the Han Chinese population has not been studied. A large-scale epidemiological study was carried out between October 2007 and September 2011 in 15 924 Han Chinese women of reproductive age (19-45 years) from the 10 provinces and municipalities in China. A total of 16 886 women from 152 cities and 112 villages were involved in the study. All study participants received a questionnaire and underwent a physical and transvaginal ultrasound examination. Blood samples were collected from a subsample of women (n = 3565) for analysis of metabolic markers and hormones. Based on the Rotterdam PCOS criteria, we assessed hyperandrogenism (H), chronic anovulation (O) and polycystic ovaries (P). Following diagnosis, women with PCOS were assigned to one of four different phenotypes. Finally, the prevalence and related risks of PCOS among Chinese women were estimated based on all the data sources. A total of 16 886 women were initially involved in the study and 15 924 eligible participants then completed the study; the overall response rate was 94.3% (15 924/16 886). The prevalence of PCOS in the Chinese community population was 5.6% (894/15 924). Blood samples were analyzed from 833 of these women who were assigned to the four PCOS phenotypes as follows: 19% H + O, 37% H + P, 15% O + P and 29% H + O + P. Comparing the 833 women with PCOS to 2732 women without PCOS indicated that PCOS occurs in younger women (P < 0.05) and these women were prone not only to menstrual problems, hyperandrogenism, PCO and infertility but also metabolic syndrome (MS) and insulin resistance (IR). However, there was no significant difference in the rate of hypertension or hyperlipemia between the two groups. Obese patients with PCOS had a

    Full Text Available Polycystic ovary syndrome (PCOS is a common condition with both a reproductive and metabolic phenotype. Women with PCOS often seek care because of infertility or menstrual cycle irregularities that result from chronic anovulation interspersed with occasional ovulatory cycles. Initially, it is important to delineate a differential diagnosis for oligo- or amenorrhea and to evaluate for disorders that may “masquerade” as PCOS. If fertility is a desired goal, then it is critical to optimize health conditions that impact fertility and gestation. Lifestyle modifications, including nutritional counseling and weight loss, should be a part of all treatment plans. Even minimal (5% weight loss in obese women with PCOS improves both ovulation and pregnancy rates. The first line of treatment for ovulation induction remains the selective estrogen receptor modulator (SERM clomiphene citrate. The role of insulin sensitizers, particularly metformin, remains unclear. A recent consensus panel recommended against its routine use in the absence of an elevated glucose or hemoglobin A1c. If a woman fails to achieve pregnancy after a trial of weight loss and six ovulatory cycles induced by clomiphene citrate, then ovulation induction with exogenous gonadotropin, with or without timed intrauterine insemination, or in vitro fertilitization, is a reasonable next step. Women with PCOS are particularly prone to excessive follicle development and are at increased risk for ovarian hyperstimulation syndrome (OHSS. Although limited data exist comparing approaches to ovulation induction or controlled ovarian stimulation in women with PCOS, the American Society for Reproductive Medicine recommends the use of “step-up” or “step-down” protocols in which a low dose of exogenous FSH or combined gonadotropins are employed in an attempt to constrain ovarian responsiveness. In vitro fertilization allows for the transfer of only one embryo or for cryopreservation of all

    Full Text Available Ovulatory menstrual cycles are essential for women's fertility and needed to prevent bone loss. There is a medical/cultural expectation that clinically normal menstrual cycles are inevitably ovulatory. Currently within the general population it is unknown the proportion of regular, normal-length menstrual cycles that are ovulatory. Thus, the objective of this study was to determine the population point prevalence of ovulation in premenopausal, normally menstruating women. The null hypothesis was that such cycles are ovulatory.This is a single-cycle, cross-sectional, population-based study-a sub-study of the HUNT3 health study in the semi-rural county (Nord Trøndelag in mid-Norway. Participants included >3,700 spontaneously (no hormonal contraception menstruating women, primarily Caucasian, ages 20-49.9 from that county. Participation rate was 51.9%. All reported the date previous flow started. A single, random serum progesterone level was considered ovulatory if ≥9.54 nmol/L on cycle days 14 to -3 days before usual cycle length (CL.Ovulation was assessed in 3,168 women mean age 41.7 (interquartile range, [IQR] 36.8 to 45.5, cycle length 28 days (d (IQR 28 to 28 and body mass index (BMI 26.3 kg/m2 (95% CI 26.1 to 26.4. Parity was 95.6%, 30% smoked, 61.3% exercised regularly and 18% were obese. 1,545 women with a serum progesterone level on cycle days 14 to -3 were presumed to be in the luteal phase. Of these, 63.3% of women had an ovulatory cycle (n = 978 and 37% (n = 567 were anovulatory. Women with/ without ovulation did not differ in age, BMI, cycle day, menarche age, cigarette use, physical activity, % obesity or self-reported health. There were minimal differences in parity (96.7% vs. 94.5%, P = 0.04 and major differences in progesterone level (24.5 vs. 3.8 nmol/L, P = 0.001.Anovulation in a random population occurs in over a third of clinically normal menstrual cycles.

    Full Text Available Background. Polycystic ovary syndrome (PCOS is the most common female endocrinopathy of reproductive age affecting 15–22 % of women according to European standards. It is a multisystem reproductive-metabolic disorder and its diagnostics and treatment remain controversial. Women with PCOS are at increased risk of developing type II diabetes, metabolic syndrome, cardiovascular disease, depression, non-alcoholic fatty liver disease, endometrial hyperplasia and cancer and few other types of carcinoma. Due to all above, early correct diagnosis, treatment and permanent surveillance of PCOS are of great importance. The main difficulty with diagnosis of PCOS was until recently lack of clear diagnostic criteria. In 2003 the European Society for Human Reproduction and Embryology and the American Society for Reproductive Medicine published a definition of PCOS. For a diagnosis of PCOS two of three criteria have to be met: oligo- or chronic anovulation (less than 8 menses per year or menses that occur at intervals greater than 35 days, clinical or biochemical signs of hyperandrogenism (alopecia, hirsutism, seborrhoea, acne, virilism, polycystyc ovaries seen on vaginal ultrasound (VUS (presence of 12 or more follicles in both ovaries measuring 2–9 mm in diameter and/or ovarian volume larger than 10 cm3 of either or both ovaries. Exclusion of other diseases with similar clinical presentation is necessary. Treatment depends on the age of the patient, predominating clinical signs and aim we try to achieve. First-line treatment for all patients includes life-style changes and weight reduction in obese patients. Management of adolescent patients is aimed at abolishment of menses irregularity and endometrial protection, treatment of hyperandrogenism, obesity, and insulin resistance (IR. In the first-line treatment we also recommend oral hormonal contraceptives (OHC with non-androgenic gestagens (NG with or without antiandrogens (AA and topical dermatological

    Mayer-Rokitansky-Küster-Hauser Syndrome (MRKHS) is characterized by complete or partial absence of the vagina, uterus and proximal fallopian tubes and diagnosis is usually made in late adolescence, when primary amenorrhea appears as the major symptom. Polycystic Ovary Syndrome (PCOS), which is the most common endocrine disorder among women of reproductive age, includes a variety of clinical manifestations (menstrual irregularities, hirsuitism, acne, alopecia, obesity and infertility), due to androgen hypersecretion, insulin resistance and chronic anovulation. Both MRKHS and PCOS have been studied concerning the psychological aspects and have been associated with emotional distress as well as self-esteem, body image, identity and femininity impairment. The purpose of this study was to assess psychological functioning in adolescents with uterovaginal agenesis and primary amenorrhea due to MRKHS and those with hyperandrogenism and oligomenorrhea due to PCOS, compared with healthy adolescents. The participants were 70 adolescent girls, of whom 24 with MRKHS, 22 with PCOS and 24 healthy eumenorrheic adolescents (control group) matched by age and school grade. Psychological assessment included self report questionnaires, standardized in Greek population sample. Particularly, the "Beck Depression Inventory" (BDI), the "State-Trait Anxiety Inventory" (STAI-Gr) and the "Youth Self Report" (YSR) were used to measure depression, anxiety and psychopathology respectively, while the "Symptom Checklist-90-R" was used to measure psychopathology for the patients >18 years old. The results showed significantly higher scores on the state - anxiety scale for the MRKHS group compared with the control group. The MRKHS patients in late adolescence (18-20 years old) presented also significantly higher scores in depression and psychopathology scales (symptoms of anxiety, aggressive behavior and phobic disorder) than PCOS patients of the same age. On the contrary, regarding PCOS patients

    How can we predict chances of natural conception at various time points in couples diagnosed with unexplained subfertility? We developed a dynamic prediction model that can make repeated predictions over time for couples with unexplained subfertility that underwent a fertility workup at a fertility clinic. The most frequently used prediction model for natural conception (the 'Hunault model') estimates the probability of natural conception only once per couple, that is, after completion of the fertility workup. This model cannot be used for a second or third time for couples who wish to know their renewed chances after a certain period of expectant management. A prospective cohort studying the long-term follow-up of subfertile couples included in 38 centres in the Netherlands between January 2002 and February 2004. Couples with bilateral tubal occlusion, anovulation or a total motile sperm count conception, leading to an ongoing pregnancy. Follow-up time was censored at the start of treatment or at the last date of contact. In developing the new dynamic prediction model, we used the same predictors as the Hunault model, i.e. female age, duration of subfertility, female subfertility being primary or secondary, sperm motility and referral status. The performance of the model was evaluated in terms of calibration and discrimination. Additionally, we assessed the utility of the model in terms of the variability of the calculated predictions. Of the 4999 couples in the cohort, 1053 (21%) women reached a natural conception leading to an ongoing pregnancy within a mean follow-up of 8 months (5th and 95th percentile: 1-21). Our newly developed dynamic prediction model estimated the median probability of conceiving in the first year after the completion of the fertility workup at 27%. For couples not yet pregnant after half a year, after one year and after one and a half years of expectant management, the median probability of conceiving over the next year was estimated at

Se caracteriza por la presencia de hiperandrogenismo, oligo-anovulación y ovarios poliquísticos. Entre los genes candidatos se encuentran aquellos que codifican para enzimas que actúan en la síntesis de andrógenos. Dos de los genes candidatos son el CYP17 y el CYP11alfa que codifican para la 17alfa hidroxilasa (P45017alfa y para el P450scc (colesterol side chain cleavage respectivamente. Los polimorfismos en estos genes están asociados al desarrollo del fenotipo hiperandrogénico. Nuestro objetivo fue analizar las frecuencias alélicas de los polimorfismos de los dos genes mencionados en población con PCOS, compararla con población normal y analizar la relación de cada variante alélica con el fenotipo hiperandrogénico correspondiente. Se analizaron 65 pacientes y 58 controles sanos en los que se determinaron niveles de testosterona y frecuencia de polimorfismos en los genes mencionados. Se observó una diferencia estadísticamente significativa cuando se asoció el grupo de mayor nivel de androgenemia con la presencia del genotipo A2/A2 del gen CYP17, y se hallaron mayores niveles de andrógenos circulantes en las pacientes con PCOS portadoras del alelo 216- del gen CYP11alfa. Nuestros resultados sugieren que ambos alelos juegan un rol menor en el desarrollo de PCOS y podrían ser considerados como potenciales marcadores de riesgo genético para el desarrollo del fenotipo hiperandrogénico.The polycystic ovary syndrome (PCOS is a heterogeneous multifactorial endocrine metabolic disorder with genetic predisposition affecting 6% of women in the reproductive age.

    Clomiphene citrate (CC) is generally considered first-line treatment in women with anovulation due to polycystic ovary syndrome (PCOS). Ovulation induction with follicle-stimulating hormone (FSH; gonadotrophins) is second-line treatment for women who do not ovulate or conceive while taking CC. Metformin may increase the effectiveness of ovulation induction with gonadotrophins and may promote safety by preventing multiple pregnancy. To determine the effectiveness and safety of metformin co-treatment during ovulation induction with gonadotrophins with respect to rates of live birth and multiple pregnancy in women with PCOS. We searched the Cochrane Gynaecology and Fertility (CGF) Group specialised register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO and the Cumulative Index to Nursing and Allied Health Literature (CINAH) on 8 June 2016, and the reference lists of included and other relevant studies. We searched ongoing trials registries in the World Health Organization (WHO) portal and on clinicaltrials.gov on 4 September 2016. We included randomised controlled trials (RCTs) reporting data on comparison of clinical outcomes in women with PCOS undergoing ovulation induction with gonadotrophins plus metformin versus gonadotrophins alone or gonadotrophins plus placebo. We used standard methodological procedures recommended by Cochrane. Primary review outcomes were live birth rate and multiple pregnancy rate. Secondary outcomes were ovulation rate, clinical pregnancy rate, ovarian hyperstimulation syndrome (OHSS) rate, miscarriage rate, cycle cancellation rate and adverse effects. We included five RCTs (with 264 women) comparing gonadotrophins plus metformin versus gonadotrophins. The gonadotrophin used was recombinant FSH in four studies and highly purified FSH in one study. Evidence was of low quality: The main limitations were serious risk of bias due to poor reporting of study methods and blinding of participants and

    The use of insulin-sensitising agents, such as metformin, in women with polycystic ovary syndrome (PCOS) who are undergoing ovulation induction or in vitro fertilisation (IVF) cycles has been widely studied. Metformin reduces hyperinsulinaemia and suppresses the excessive ovarian production of androgens. As a consequence, it is suggested that metformin could improve assisted reproductive techniques (ART) outcomes, such as ovarian hyperstimulation syndrome (OHSS), pregnancy and live birth rates. To determine the effectiveness and safety of metformin as a co-treatment during IVF or intracytoplasmic sperm injection (ICSI) in achieving pregnancy or live birth in women with PCOS. We searched the Cochrane Menstrual Disorders and Subfertility Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, LILACS, the metaRegister of Controlled Trials and reference lists of articles (up to 15 October 2014). Types of studies: randomised controlled trials (RCTs) comparing metformin treatment with placebo or no treatment in women with PCOS who underwent IVF or ICSI treatment. women of reproductive age with anovulation due to PCOS with or without co-existing infertility factors.Types of interventions: metformin administered before and during IVF or ICSI treatment.Types of outcome measures: live birth rate, clinical pregnancy rate, miscarriage rate, incidence of ovarian hyperstimulation syndrome , incidence of participant-reported side effects, serum oestradiol level on the day of trigger, serum androgen level, and fasting insulin and glucose levels. Two review authors independently selected the studies, extracted the data according to the protocol and assessed study quality. The overall quality of the evidence was assessed using GRADE methods. We included nine randomised controlled trials involving a total of 816 women with PCOS. When metformin was compared with placebo there was no clear evidence of a difference

The aim of this study was to identify the artery that first is affected by early pre-atherosclerotic changes in PCOS. Methods: Twenty-nine women with PCOS aged 17 to 27 years and 26 healthy nonhyperandrogenic volunteers with regular menses (control women aged 16 to 28 years were enrolled. All PCOS patients were overweight or obese (body mass index [BMI] ≥ 25. Diagnosis of PCOS was performed in line with the 2003 Rotterdam ESHRE/ASRM-Sponsored PCOS Consensus Workshop Group. Accordingly, PCOS was defined when at least two of the following three features were present after exclusion of other etiologies: 1 oligomenorrhea and or anovulation; 2 hyperandrogenism and/or hyperandrogenemia; and 3 polycystic ovaries visible at ultrasound. Androgen excess or related disorders were excluded. The intima-media thickness (IMT of common carotid arteries and common femoral arteries and the anteroposterior diameter of the infrarenal abdominal aorta were measured by ultrasound. Lutenizing hormone (LH, follicle-stimulating hormone (FSH, estradiol, total testosterone, androstenedione, and sex hormone-binding globulin (SHBG serum levels were measured between the 3rd and the 6th day of spontaneous or progestin-induced menstrual cycle. Our study was performed in the absence of any medical treatment. Results: Women with PCOS showed a higher LH to FSH ratio (p < 0.01, increased fasting insulin (p < 0.001, total testosterone (p < 0.001, and androstenedione (p < 0.001 levels, and lower

    hyperandrogenemia and hyperprolactinemia. So, as compared to the group of control on the 14th day of cycle LH, FSH, and estradiol, progesterone, while free testosterone, DGEA were enhanced as compared to control data. In the second group of patients the reliable decline of pituitary hormones was also educed on a background of hyperandrogenemia and hyperprolactinemia while an ovarian function was within the normal limits. So, as compared to the group of control on the 14th day of cycle the LH, FSH, here free testosterone, DGEA and АМH levels were enhanced as compared to control data. The neuroimaging of hypophysis in patients with PCOS educed hyperplasia (adenomatosis of hypophysis in 49 from 120 (40.8 %, that can be explained by ovarian insufficiency in these patients. On the second place by incidence there was the syndrome of the empty sella (26 cases, 21.6 %, and on the third — the microadenoma of hypophysis in 16 persons (13.3 %. Conclusions. In the first group of patients with primary sterility the reliable decline of both pituitary and ovarian hormones was marked on a background of hyperandrogenemia and hyperprolactinemia. In the second group of patients the significant decline of pituitary hormones was also educed on a background of hyperanrogenemia and hyperprolactinemia, while an ovarian function was within the normal limits. In both groups of patients hypogonadotropinemia occurred combined with moderate hyperprolactinemia and hyperandrogenemia. Thus, the most expressed violations of the system of pituitary — ovarian function were found out in the first group of patients with PCOS with primary sterility, at that the significant decline of the functional status of pituitary — gonads axis was marked, namely decline of LH, FSH, estradiol and progesterone levels on the 14th day of menstrual cycle, that was confirmed by ultrasouns examination of uterus and ovaries by impoverishment of follicle vehicle of ovaries, anovulation signs. Thus, the most expressed violations of

    Polycystic ovary syndrome (PCOS) is a common endocrine condition, affecting approximately one in 10 women. PCOS is defined by two of three features: oligo- or anovulation, clinical or biochemical hyperandrogenism or both, or polycystic ovaries.Women with PCOS can have a wide range of health problems, including infrequent and irregular periods, unwanted hair growth and acne, and subnormal fertility. Long-term health concerns include an increased risk of heart disease, diabetes and the development of precancerous disease of the womb. To assess the effectiveness and harms of ovarian surgery as a treatment for symptomatic relief of hirsutism, acne and menstrual irregularity in PCOS. We searched the Cochrane Gynaecology and Fertility Group specialized register, CENTRAL, MEDLINE, Embase and PsycINFO (from inception to 17 October 2016). We handsearched citation lists, registers of ongoing trials and conference proceedings. We included randomized controlled trials (RCTs) of women undergoing ovarian drilling in comparison to no treatment, medical treatment, or other forms of surgical treatment for the symptoms of PCOS. We used standard methodological procedures recommended by Cochrane. The primary outcome measures were improvement in menstrual regularity and androgenic symptoms of PCOS (hirsutism, acne); the secondary outcome measures included harms, change of body mass index (BMI), waist circumference, androgen levels, metabolic measures and quality of life. We assessed the quality of the evidence using GRADE methods. We included 22 RCTs (2278 women analyzed) of participants with PCOS and symptoms of acne, hirsutism or irregular menstrual cycles, all of which included laparoscopic ovarian drilling (LOD) as an intervention.Two studies reported their funding source (Farquhar 2002 - supported in part by the Auckland Medical Research Foundation; Sarouri 2015 - the authors thank the Vice Chancellor for Research of Guilan University of Medical Sciences for funding this project
