Abstract
Infertility is a globally recognized issue caused by different reproductive disorders. To date, various therapeutic approaches to restore fertility have been attempted including etiology-specific medication, hormonal therapies, surgical excisions, and assisted reproductive technologies. Although these approaches produce results, however, fertility restoration is not achieved in all cases. Advances in using stem cell (SC) therapy hold a great promise for treating infertile patients due to their abilities to self-renew, differentiate, and produce different paracrine factors to regenerate the damaged or injured cells and replenish the affected germ cells. Furthermore, SCs secrete extracellular vesicles (EVs) containing biologically active molecules including nucleic acids, lipids, and proteins. EVs are involved in various physiological and pathological processes and show promising non-cellular therapeutic uses to combat infertility. Several studies have indicated that SCs and/or their derived EVs transplantation plays a crucial role in the regeneration of different segments of the reproductive system, oocyte production, and initiation of sperm production. However, available evidence triggers the need to testify the efficacy of SC transplantation or EVs injection in resolving the infertility issues of the human population. In this review, we highlight the recent literature covering the issues of infertility in females and males, with a special focus on the possible treatments by stem cells or their derived EVs.

Abstract
Background: Polycystic ovary syndrome (PCOS), the major endocrinopathy among reproductive-aged women, is not yet perceived as an important health problem in the world. It affects 4%–20% of women of reproductive age worldwide. The prevalence, diagnosis, etiology, management, clinical practices, psychological issues, and prevention are some of the most confusing aspects associated with PCOS. Aim: The exact prevalence figures regarding PCOS are limited and unclear. The aim of this review is to summarize comprehensively the current knowledge on the prevalence of PCOS. Materials and Methods: Literature search was performed through PubMed, ScienceDirect, Cochrane Library, and Google Scholar (up to December 2019). All relevant articles published in English language were identified following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Our analysis yielded 27 surveys with a pooled mean prevalence of 21.27% using different diagnostic criteria. The proportion of women with PCOS also increased in the last decade. Conclusion: The current review summarizes and interprets the results of all published prevalence studies and highlights the burden of the syndrome, thereby supporting early identification and prevention of PCOS in order to reverse the persistent upward trend of prevalence.

Abstract
INTRODUCTION Polycystic ovary disease is a common endocrine condition which is rapidly gaining epidemic proportions. No community based prevalence data is available for this syndrome in India. MATERIALS AND METHODS A cross-sectional community-based study was undertaken in a sampled census block of Mumbai to assess the prevalence of polycystic ovarian syndrome (PCOS) among 778 adolescents and young girls aged 15-24 years. Among them, 600 completed all clinical, ultrasonography (USG), and biochemical investigations. RESULTS The prevalence of PCOS among them was 22.5% by Rotterdam and 10.7% by Androgen Excess Society criteria. Nonobese comprised 71.8% of PCOS diagnosed by Rotterdam criteria. Mild PCOS (oligomenorrhea and polycystic ovaries on USG) was the most common phenotype (52.6%). History of oligomenorrhea had a positive predictive value of 93.3% and negative predictive value of 86.7% to detect a possible case of PCOS. Hyperinsulinemia (serum insulin >15 μlU/mL) was present among 19.2% of diagnosed PCOS cases. Obese girls with PCOS were more hirsute, hypertensive, and had significantly higher mean insulin and 2 h post 75 g glucose levels compared with nonobese PCOS. CONCLUSION To our knowledge, this is the first urban community-based study diagnosing PCOS and phenotypes among adolescent and young girls in India. This study demonstrates that PCOS is an emerging disorder during adolescence and screening could provide opportunity to target the group for promoting healthy lifestyles and early interventions to prevent future morbidities.

Abstract
In most of South Asia, prevalences and phenotypes of polycystic ovary syndrome (PCOS) among women in the community are unknown. The authors aimed to estimate prevalence and phenotype in a community setting in Sri Lanka and to test a valid, feasible screening approach to early diagnosis. A community-based, cross-sectional study was carried out in 2005-2006. A random sample of 3,030 women aged 15-39 years was selected by cluster sampling proportionate to population size. An interviewer-administered questionnaire was utilized to screen for "probable cases" of PCOS based on menstrual history and clinical manifestations of hyperandrogenism. Selected "probable cases" underwent clinical, biochemical, and ovarian ultrasound assessment. The response rate was 96.2% (n = 2,915). A total of 220 (7.5%) "probable cases" were identified: 209 women with oligo/amenorrhea (95%) and 11 women with hirsutism (5%). Further evaluation of the 220 probable cases confirmed 164 newly diagnosed cases of PCOS based on the 2003 Rotterdam diagnostic criteria. With 19 previously diagnosed cases already present, total prevalence was 6.3% (95% confidence interval: 5.9, 6.8). Of the women with "oligo/amenorrhea and/or hirsutism," 91.1% were confirmed to have PCOS; 99.4% of women with "regular cycles in the absence of clinical hyperandrogenism" were confirmed as normal. The most common phenotypes of PCOS were oligo/amenorrhea and polycystic ovaries (91.4%) and oligo/amenorrhea and hirsutism (48.3%).

Abstract
PURPOSE Many women with polycystic ovarian syndrome (PCOS) are overweight. This study investigated the impact of weight loss surgery on the clinical manifestations of this disorder in morbidly obese women with PCOS-a major risk factor for the development of heart disease, stroke, and type II diabetes. METHODS We reviewed the outcomes of women diagnosed with PCOS who had undergone weight loss surgery at the University of Pittsburgh between July 1997 and November 2001. We evaluated the changes in menstrual cycles, hirsutism, infertility, and type II diabetes. RESULTS A total of 24 women with PCOS were included in the study. Their mean age was 34 +/- 9.7 years. The mean preoperative body weight was 306 +/- 44 lb, with a body mass index of 50 +/- 7.5. All patients were oligomenorrheic. Of the 24 patients, 23 were hirsute. All women underwent elective laparoscopic gastric bypass surgery. The mean follow-up period was 27.5 +/- 16 months. The mean excess weight loss at 1 year of follow-up was 56.7% +/- 21.2%. All women resumed normal menstrual cycles after a mean of 3.4 +/- 2.1 months postoperatively. Of the 23 women with hirsutism, 12 (52%) had complete resolution at a mean follow-up of 8 +/- 2.3 months, 6 (25%) had moderate resolution at a mean of 21 +/- 18 months, and 3 had minimal resolution at 34 +/- 14 months. Two women reported no change in their hirsutism at 32 +/- 7 months. Five women were able to conceive after surgery without the use of clomiphene. CONCLUSION Gastric bypass surgery and its consequent weight loss results in significant improvement of multiple clinical problems related to PCOS.

Abstract
OBJECTIVE To investigate the role of serine-threonine phosphorylation on the activity of human P450c17. DESIGN In vitro study. SETTING Academic basic research laboratory. PATIENT(S) None. INTERVENTION(S) P450c17 expression constructs with a FLAG-tag on either the C-terminus or N-terminus of the protein were generated. Human C-terminal FLAG-tagged P450c17 chromosomal DNA was subjected to site-directed mutagenesis. Serine 258 and threonine 260 each were mutated to alanine and aspartic acid. The mutant P450c17s were expressed in COS-7 cells, and the enzymatic activities were measured. MAIN OUTCOME MEASURE(S) 17alpha-Hydroxylase and C(17-20) lyase activities of human P450c17. RESULT(S) C-terminal FLAG-tagged P450c17 functioned indistinguishably from the wild-type P450c17. Mutants S258A, S258D, and T260D had significantly less 17alpha-hydroxylase and C(17-20) lyase activities than the wild type. CONCLUSION(S) Adding an epitope tag to the C-terminus of the P450c17 protein does not interfere with its activities and will be a useful tool to isolate human P450c17 protein from cultured cells. Phosphorylation of serine 258 but not threonine 260 may act as a physiologic regulator of both enzymatic activities through interaction with obligatory redox partners.

Abstract
The classic polycystic ovarian syndrome (PCOS) was originally described by Stein and Leventhal as the association of amenorrhea with polycystic ovaries and, variably, hirsutism and/or obesity. It is estimated that 5 to 10% of women of reproductive age have PCOS. Although insulin resistance is not part of the diagnostic criteria for PCOS, its importance in the pathogenesis of PCOS can not be denied. PCOS is associated with insulin resistance, independent of total or fat-free body mass. Postreceptor defects in the action of insulin have been described in PCOS that are similar to those found in obesity and type 2 diabetes. Treatment with insulin sensitizers, metformin, and thiazolidinediones (TZDs) improve both metabolic and hormonal patterns and also improve ovulation in PCOS. Recent studies have shown that women who have PCOS have higher circulating levels of inflammatory mediators such as C-reactive protein, tumor necrosis factor, tissue plasminogen activator, and plasminogen activator inhibitor-1 (PAI-1). It is possible that the beneficial effect of insulin sensitizers in PCOS may be partly due to a decrease in inflammation.

Abstract
Our understanding of Polycystic Ovary Syndrome (PCOS) has been hampered by varying diagnostic criteria, and ignorance of the etiology of the syndrome. PCOS women are uniquely insulin resistant and obesity aggravates this underlying predisposition to insulin resistance. Diagnostic criteria which focus on hyperandrogenism and/or menstrual irregularity are more likely to identify insulin resistant women, than such criteria as abnormal gonadotropin secretion or ovarian morphology. The lack of a clear etiologic mechanism to the syndrome has led to a multitude of symptom-oriented treatments with few therapies improving all aspects of the endocrine syndrome of PCOS. Improving insulin sensitivity has become established as a baseline treatment strategy in PCOS. There are, however, few randomized controlled trials of adequate power to provide an evidence based guide to treatment in PCOS.

Abstract
STUDY OBJECTIVE To analyze the efficacy of laparoscopic ovarian drilling using monopolar diathermy in women with anovulatory infertility with clomiphene-resistant polycystic ovary syndrome (PCOS), and to determine factors influencing pregnancy rate and pregnancy outcomes. DESIGN Prospective study (Canadian Task Force classification II-2). SETTING Infertility clinic in a tertiary referral teaching hospital. PATIENTS Seventy women with clomiphene-resistant PCOS. INTERVENTION Laparoscopic ovarian drilling, with follow-up for 4.5 years. MEASUREMENTS AND MAIN RESULTS Follow-up data, which were available for 66 patients, showed a spontaneous ovulation rate of 81.8%, cumulative ovulation rate of 93.9%, and pregnancy rate of 54.5%. Successful pregnancies were commonly complicated by gestational diabetes mellitus and pregnancy-induced hypertension. Pregnancy rates (23.5%) were low in women with tuboperitoneal disease and those whose partners had subfertile male factors. Statistical evaluation using a proportion test (Z test) and multivariable logistical regression analysis showed that elevated luteinizing hormone levels (>10 IU/L), short duration of infertility (<3 yrs), and absence of preexisting tubal disease were associated with better outcomes. CONCLUSION Laparoscopic ovarian drilling is an effective surgical procedure in women with clomiphene-resistant PCOS.

Abstract
In a preview study we found that luteinizing granulosa cells from follicles of patients with polycystic ovary syndrome (PCOS) have a reduced capacity to synthesize progesterone in vitro. Because the 3 beta-hydroxysteroid dehydrogenase/delta 5-delta 4-isomerase (3 beta-HSD) is an important enzyme for the biosynthesis of progesterone, the reduced capacity of PCO luteinizing granulosa cells to synthesize progesterone in vitro may be due to reduced 3 beta-HSD gene expression. A reverse transcriptase polymerase chain reaction for 3 beta-HSD was performed and the relative intensity of signals for 3 beta-HSD was evaluated using computer-assisted densitometry. Cells from polycystic ovaries expressed less 3 beta-HSD in follicles < or 10 mm (p < 0.05) and in follicles > or 16 mm (p < 0.05) than cells from normal ovaries. Furthermore, after human chorionic gonadotropin stimulus (50 ng/ml), cells from polycystic ovaries expressed less 3 beta-HSD in follicles > or = 16 mm (p < 0.01) than cells from normal ovaries. The data show that there is a specific change in the gene expression of 3 beta-HSD in PCO granulosa cells resulting in a suppressed capacity to secrete progesterone.

Abstract
The clinical features of polycystic ovary syndrome (PCOS) include hirsutism and irregular menses, which are the results of ovarian hyperandrogenism and chronic, unopposed estrogen secretion. The discovery that most women with PCOS are insulin-resistant and have compensatory hyperinsulinemia, with increased risk for type 2 diabetes mellitus, designates this condition as a reproductive-metabolic disorder. That the symptoms of PCOS may be mimicked by other endocrine disorders of the ovary and adrenal glands warrants careful evaluation to exclude these associated conditions.

Abstract
In an effort to elucidate the aetiology of female-to-male transsexualism (FM-TS) 12 out of an annual sample of 16 untreated female-to-male transsexuals (FMT), aged 19 years 7 months (19;7) to 44 years 8 months (44;8) [median age (M) 27;5] were assessed by means of sexual-medical questionnaires, physical and endocrinological examination. The control group consisted of 15 healthy women (CF), aged 19 years 2 months (19;2) to 36 years 1 month (36;1) (M 22;7) without gender identity disorder, who were not under hormonal medication (including contraceptives). Baseline levels of testosterone (T; ng/dl), androstenedione (A4; ng/dl), dehydroepiandrosterone sulfate (DHEAS; ng/ml), luteinizing hormone (LH; IU/l), follicle stimulating hormone (FSH; IU/l), and sex-hormone binding globuline (SHBG; microgram/dl) were measured. A standard single-dose ACTH stimulation test (250 micrograms ACTH IV; Synacthen) was performed with all subjects. Aldosterone (ALDO), corticosterone (B), deoxycorticosterone (DOC), progesterone (PROG), 17-hydroxyprogesterone (17OHP), 11-deoxycortisol (S), cortisol (F), cortisone (E), pregnenolone (PREG) and 17-hydroxypregnenolone (OHPREG) were assessed before and 60 min after ACTH stimulation. Transvaginal ultrasound was performed in nine out of 12 FMT (20;11 to 44;8, M 27;5; m 29.1 +/- 7.5) but not in CF. Results showed that 10 FMT (83.3%) and five CF (33.3%) were above normal values for at least one of the measured androgens. Baseline levels of T and A4 were significantly higher in FMT than in CF (T: 54.0 +/- 13.8 vs. 41.1 +/- 12.8; A4: 244.8 +/- 73.0 vs. 190.5 +/- 49.3; p < .05), whereas DHEAS, SHBG, LH and FSH did not differ between the groups. Unbound T (T/SHBG ratio) was higher in FMT (72.0 +/- 67.6) than in CF (26.4 +/- 15.1). Baseline levels of 17OHP, OHPREG and DOC were higher in FMT than in CF (p < .05). After ACTH stimulation 17OHP and OHPREG remained higher in FMT than in CF (p < .05). Single case analysis of ACTH stimulation test together with physical examination revealed symptoms for non-classical congenital adrenal hyperplasia (NC-CAH) in six FMT (50%) and two CF (13.3%). Eight out of nine FMT who were assessed by means of transvaginal ultrasound (i.e. 88.9%; 50.0% of 16) had polycystic ovaries (PCO). Oligomenorrhoea or menstrual dysregularities (81.7% of 16 FMT vs. 0% of CF), hirsutism (56.2% of 16 FMT vs. 13.3% of 15 CF) and adiposity (25.0% vs. 0%) were frequent in FMT, but not in CF. Hyperandrogenism with polycystic ovarian syndrome (PCOS) and adrenocortical hyperresponsiveness to ACTH seems to be a common finding in FMT. This offers support for a hormonal factor in the genesis of FM-TS. Because the prevalence of PCOS and NC-CAH in the female population is higher than FM-TS, the true nature of this factor and its interaction with environmental influences remains unknown.

Abstract
The ovary and testis are sites for interaction between the endocrine and immune system via leukocytes and their secreted products, the cytokines. There are convincing data available to show that the gonads are sites of cytokine action and production. In the ovary, cytokines and leukocytes are intimately involved in follicular development, ovulation, and luteal function. A variety of clinical situations may be due to cytokine action in the gonads, and therapeutic manipulation of the immune system may affect reproductive function.
