Abstract
INTRODUCTION Hirsutism is a prevalent condition among women and represents a primary clinical feature of polycystic ovary syndrome (PCOS). AREAS COVERED Our study aims to address the principal challenges associated with this hyperandrogenic manifestation in PCOS women. Our narrative review based on the available indexed literature explored the complexities of establishing mFG cutoff values for various ethnic groups, investigated hirsutism during peri- and postmenopausal stages, and examined the role of oxyandrogens. EXPERT OPINION Hirsutism may have a negative impact on the quality of life and on the mental health, being associated with anxiety and depression. Future perspectives for its diagnosis include the use of artificial intelligence and the consideration of the distress caused by excessive hair growth.

Increased Prevalence of Elevated DHEAS in PCOS Women with Non-Classic (B or C) Phenotypes: A Retrospective Analysis in Patients Aged 20 to 29 Years. Cells 2022; 11:cells11203255. [PMID: 36291122 PMCID: PMC9601254 DOI: 10.3390/cells11203255] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 09/26/2022] [Accepted: 10/13/2022] [Indexed: 11/16/2022] Open
Abstract
It is well known that a subgroup of women with PCOS present an excessive adrenal androgen production, generally associated with ovarian hyperandrogenism. In the past, it has been impossible to correlate adrenal hyperandrogenism to any clinical or hormonal pattern of PCOS. However, adrenal androgens are strictly dependent on age and their blood values reduce by 40% in patients moving from their twenties to thirties. Due to this, serum DHEAS values are strongly influenced by the age distribution of studied populations. To avoid this bias, in this study we retrospectively analyzed the clinical and hormonal data of PCOS women in their twenties (age between 20 and 29 years). Data of 648 young hyperandrogenic women with PCOS were evaluated. Serum DHEAS was increased in a third (33%) of studied patients and was associated with higher values of testosterone (T) and androstenedione (A). In each phenotype, patients with high DHEAS had higher values of T and A than patients with normal DHEAS of the same phenotype. Therefore, a DHEAS increase is generally part of a generalized higher androgen production in a subgroup of PCOS patients, independently of the finding of anovulatory or ovulatory cycles or of polycystic or normal ovaries. However, our study showed some important differences between PCOS phenotypes. A lower prevalence of increased DHEAS in A phenotype PCOS patients who generally have the highest androgen levels, versus non-classic (B or C) PCOS phenotypes, was observed. It was also found that patients with A phenotype PCOS present significantly lower BMI and serum insulin than patients with normal DHEAS of the same phenotype while, in patients with the B or C phenotype, the opposite occurs. We conclude that adrenal hyperandrogenism is more common in patients with non-classic (B and C) phenotypes of PCOS and is generally part of a generalized higher production of androgens in a subgroup of PCOS patients. However, other factors may increase the adrenal androgen production and influence the clinical expression of the syndrome. More studies in large, selected for age, populations of PCOS women with different phenotypes are needed.

Abstract
CONTEXT Syndromes of severe insulin resistance (SIR) include insulin receptoropathy, in which all signaling downstream of the insulin receptor is lost, and lipodystrophy, in which some signaling pathways are impaired and others preserved. Women with SIR commonly have ovarian hyperandrogenemia; adrenal-derived 11-oxygenated androgens, produced by CYP11B1, have not been studied. OBJECTIVE We aimed to evaluate classic pathway androgens (androstenedione, testosterone) and 11-oxygenated androgens in women with SIR and hyperandrogenemia, and to elucidate the role of insulin receptor signaling for 11-oxygenated androgen production by comparing lipodystrophy and receptoropathy. METHODS Steroid hormones were quantified using LC-MS/MS in a cross-sectional study of 18 women with hyperandrogenemia and SIR (11 lipodystrophy, 7 receptoropathy) and 23 controls. To assess ovarian vs adrenal origin, steroids were compared in receptoropathy patients with (Ovary+) vs without (Ovary-) ovarian function. RESULTS Compared with controls, classic androgens were elevated in both lipodystrophy and receptoropathy, and 11-oxygenated androgens were increased in lipodystrophy (2.9-fold higher 11β-hydroxyandrostenedione (11OHA4), 2.4-fold higher 11-ketoandrostenedione (11KA4), 3.6-fold higher 11-ketotestosterone (11KT); P < 0.01), but not receptoropathy. Product-to-precursor ratios for CYP11B1 conversion of androstenedione to 11OHA4 were similar in lipodystrophy and controls but decreased in receptoropathy (6.5-fold lower than control; P = 0.001). Classic androgens were elevated in Ovary + but not Ovary- patients. CONCLUSIONS 11-Oxygenated androgens are elevated in lipodystrophy but not receptoropathy. In SIR, insulin receptor signaling is necessary for adrenal hyperandrogenemia but not ovarian hyperandrogenemia; excess classic androgens are derived from the ovaries. Insulin receptor signaling increases adrenal 19-carbon steroid production, which may have implications for more common disorders of mild IR.

Abstract
OBJECTIVE To examine the possible effects of adrenal prohormones in the prediction of clinical and metabolic abnormalities in women with polycystic ovary syndrome (PCOS). METHODS The present study enrolled 299 normal cycling non-PCOS, 156 normoandrogenemic, and 474 hyperandrogenemic women with PCOS. Baseline characteristics were compared using a chi-squared test or analysis of variance (ANOVA) as appropriate. The roles of adrenal prohormones and their ratios with total testosterone in predicting co-occurring morbidities in women PCOS were evaluated using univariate and multivariate logistic regression analyses. RESULTS Adrenal hyperandrogenism per dehydroepiandrosterone sulfate (DHEAS) levels were found in 32% of women with PCOS. In non-PCOS women, dehydroepiandrosterone (DHEA) and its sulfate had no predictive role concerning clinical, anthropometric, and metabolic parameters. In PCOS women, mainly in the hyperandrogenemic group, DHEA showed to be a significant predictor against most anthropometric-metabolic index abnormalities (odds ratio [OR] = 0.36-0.97; p < 0.05), and an increase in triglycerides (TG) levels (OR = 0.76; p = 0.006). Dehydroepiandrosterone sulfate presented a few predictive effects regarding PCOS-associated disorders. In controls, DHEAS predicted against the increase in estimated average glucose (OR= 0.38; p = 0.036). In the normoandrogenic group, it predicted against elevation in the waist/hip ratio (WHR) (OR= 0.59; p = 0.042), and in hyperandrogenemic PCOS women, it predicted against abnormality in the conicity index (CI) (OR = 0.31; p = 0.028). CONCLUSION Dehydroepiandrosterone was shown to be a better predictor of abnormal anthropometric and biochemical parameters in women with PCOS than DHEAS. Thus, regarding adrenal prohormones, DHEA measurement, instead of DHEAS, should be preferred in PCOS management. The effects of androgen prohormones on the prediction of PCOS abnormalities are weak.

Abstract
The hyperandrogenism in polycystic ovary syndrome (PCOS) is associated with the risk for the future development of the cardiovascular disease. The objective of the study is to verify whether different androgens have the same harmful effect. This cross-sectional study enrolled 823 women with PCOS: 627 (76.2%) with biochemical hyperandrogenism and 196 (23.8%) with normal androgen levels. The role of individual androgen was evaluated using univariate and multivariate logistic regression. In normoandrogenemic PCOS (NA-PCOS), free androgen index (FAI) predicted significant abnormality in visceral adipose index (VAI, OR=9.2, p=0.002) and dehydroepiandrosterone (DHEA) predicted against alteration in β-cell function (OR=0.5, p=0.007). In hyperandrogenemic PCOS (HA-PCOS), FAI predicted derangements in waist triglyceride index (WTI), VAI, and lipid accumulation product (LAP) (OR ranging from 1.6 to 5.8, p<0.05). DHEA weakly predicted against VAI (OR 0.7, p=0.018), dehydroepiandrosterone sulfate (DHEAS) tended to predict against the conicity index (OR=0.7, p=0.037). After multiple regression, FAI retained significant strength to predict various anthropometric and metabolic abnormalities (OR ranging from 1.1 to 3.0, p<0.01), DHEA was kept as a protector factor against WTI, LAP, and VAI (OR ranging from 0.6 to 0.9; p<0.01) and DHEAS against the conicity index (OR=0.5, p<0.001). In conclusion, the free androgen index was the most powerful predictor of anthropometric and metabolic abnormalities of polycystic ovary syndrome. Conversely, DHEA and DHEAS demonstrated protective effects against disorders in some markers of obesity and abnormal metabolism.

Abstract
Follicular cystic ovary disease is a common reproductive disorder in women and females of domestic animals, characterized by anovulation and the persistence of follicle is a common cause of reproductive failure in mammalian. Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism (HA), chronic anovulation and polycystic ovaries, and it is a common reproductive endocrine disease with clinical manifestations including hirsutism, acne, infertility and obesity that can affect 5-20% of women in their reproductive age. Photobiomodulation (PBM) has been investigated and used in clinical practice, related to biomodulatory influences on cellular functions in animals and humans, both in vivo and in vitro. In this study, we include endocrine and reproductive features in a rat model for PCOS and the effects of PBM on ovarian activities. Forty-five adult female Wistar rats PCOS-induced by a single dose of the estradiol valerate (EV) were used in the study. After the EV injection for PCO induction, rats were divided into 9 groups (n = 5/group) named C30, C45 and C60 (Control group), S30, S45 and S60 (PCO group) and L30, L45 and L60 (PCO/Laser group). The rats were irradiated with laser 3 times/week. The results shown that EV PCO-induced rats had increased body mass, reduced ovary mass, and reduced GSI. The plasma levels of P4 and T were increased, and the LH plasma level was decreased by PBM stimulation. The number of ovarian follicles and corpus luteum were increased, and the number of ovarian cysts was decreased by PBM stimulation. Thus, reproductive and endocrine characteristics were modulated by PBM.

Abstract
BACKGROUND Insulin resistance and obesity are not universal features of polycystic ovary syndrome (PCOS). We planned to assess the differences between patients with nonobese /insulin-sensitive phenotype vs. obese/ insulin-resistant phenotype in terms of the potential mechanisms underlying their hyperandrogenism. MATERIALS AND METHODS A total of 52 women satisfying Androgen Excess Society (AES) criteria were included. Hormonal and metabolic profile including prolactin, dehydroepiandrosterone sulfate (DHEAS), free testosterone, sex hormone binding globulin (SHBG), fasting plasma glucose and insulin were measured in follicular phase. RESULTS DHEAS was found to be higher in the nonobese patients as compared to the obese (p = 0.01). There was also a strong trend for a higher DHEAS among patients with lower insulin resistance by homeostatic model assessment (HOMA-IR< 2.3) (p = .06).While the total testosterone (p = .044) and SHBG (p = .007) were found to be lower in the more insulin-resistant group (HOMA-IR ≥ 2.3), the free testosterone levels were similar. However, the percentage of free testosterone was higher in the more insulin-resistant group (p = .005). CONCLUSIONS The hyperandrogenic state in PCOS appears to have heterogenous origins. Nonobese patients with PCOS have adrenal hyperandrogenism as the underlying mechanism while their obese/ insulin-resistant counterparts have low SHBG and hence an increased fraction of free testosterone.

Abstract
OBJECTIVE The aim of this study was to investigate the impact of adrenal hyperandrogenism on insulin resistance and lipid profile in women with polycystic ovary syndrome (PCOS). PATIENTS AND METHODS We studied 372 women with PCOS according to the NIH criteria. 232 age- and BMI-matched women served as controls in order to define adrenal hyperandrogenism (DHEA-S >95th percentile). Then, patients with PCOS were classified into two groups: with adrenal hyperandrogenism (PCOS-AH, n = 108) and without adrenal hyperandrogenism (PCOS-NAH, n = 264). Anthropometric measurements were recorded. Fasting plasma glucose, insulin, lipid profile, sex hormone-binding globulin (SHBG) and androgen (TT, Δ4A, DHEA-S) concentrations were assessed. Free androgen index (FAI) and homeostatic model assessment-insulin resistance (HOMA-IR) index were calculated. RESULTS Women with PCOS-AH were younger than PCOS-NAH (P < 0.001), but did not differ in the degree and type of obesity. No differences were found in HOMA-IR, total cholesterol, HDL-c, LDL-c and triglyceride concentrations (in all comparisons, P > 0.05). These metabolic parameters did not differ between the two groups even after correction for age. Women with PCOS-AH had lower SHBG (29.2 ± 13.8 vs 32.4 ± 11.8 nmol/L, P = 0.025) and higher TT (1.0 ± 0.2 vs 0.8 ± 0.4 ng/mL, P = 0.05) and Δ4A (3.9 ± 1.2 vs 3.4 ± 1.0 ng/mL, P = 0.007) concentrations, as well as FAI (14.1 ± 8.0 vs 10.2 ± 5.0, P < 0.001). These results were confirmed by a multiple regression analysis model in which adrenal hyperandrogenism was negatively associated with age (P < 0.001) and SHBG concentrations (P = 0.02), but not with any metabolic parameter. CONCLUSIONS Women with PCOS and adrenal hyperandrogenism do not exhibit any deterioration in insulin resistance and lipid profile despite the higher degree of total androgens.

Abstract
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.

Abstract
OBJECTIVE To examine the anthropometric, and metabolic connections of 17-hydroxypregnenolone in the normo- and hyperandrogenemic polycystic ovary syndrome phenotypes. MATERIALS AND METHODS This cohort study was conducted at the Julio Muller University Hospital, Cuiabá, Brazil, between January 2014 and July 2016, and 91 normal cycling healthy women, 46 normoandrogenemic and 147 hyperandrogenemic, patients with polycystic ovary syndrome (PCOS) were enrolled according to the Rotterdam criteria. Several anthropometric, biochemical and hormonal parameters were properly verified and correlated with 17-hydroxypregnenolone (17-OHPE) concentrations. RESULTS 17-OHPE was higher in hyperandrogenemic PCOS than in normoandrogenemic PCOS and in control groups (P = 0.032 and P < 0.001, respectively). In healthy controls, 17-OHPE was positively associated with glucose, free estrogen index, DHEAS and negatively associated with compounds S. In normoandrogenemic PCOS patients, 17-OHPE presented positive correlations with VAI, LAP, cortisol, insulin and HOMA-IR. In the hyperandrogenemic group, 17-OHPE presented significant negative correlations with most anthropometric parameters, HOMA-IR, HOMA %B, estradiol, free estrogen index (FEI), C-peptide, and TG levels and positive correlations with HOMA-S and high-density lipoprotein cholesterol (HDL-C), sex-hormone binding globulin (SHBG), androstenedione (A4) and dehydroepiandrosterone (DHEA). Regarding hyperandrogenemic PCOS, and using a stepwise multiple regression, only HOMA-S and WHR were retained in the model (R2 = 0.294, P < 0.001). CONCLUSION 17-OHPE exhibited different relationships with anthropometric, and biochemical parameters in PCOS patients, depending on the androgen levels. In PCOS subjects with high androgen concentrations, 17-OHPE was negatively associated with most anthropometric parameters, particularly with those used as markers of adipose tissue dysfunction and frequently employed as predictors of cardiovascular disease risk; otherwise, 17-OHPE was positively associated with HDL-C and HOMA-S in this patients. Future studies are required to evaluate the clinical implications of these novel findings.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is associated with reproductive and metabolic abnormalities. The aim of this study was to analyse risk of cardiovascular disease (CVD) in PCOS, to define individual risk factors and assess their ability to predict risk. METHODS Fifty-four young women with PCOS (22 obese and 32 normal weight) were compared to 46 respective controls (17 obese and 29 normal weight). Anthropometric parameters, lipid status parameters, inflammation markers, concentrations of glucose, transaminases, sex and anterior pituitary hormones, sex hormone binding globulin (SHBG) and androgens were measured. Cardiovascular Risk Score (CVRS), indices for identifying Non-Alcoholic Fatty Liver Disease (NAFLD) and the Index of Central Obesity (ICO) were calculated. RESULTS Significantly higher CVRS values (p<0.05) were found in obese PCOS women compared to normal weight control and normal weight PCOS groups. Anthropometric parameters, lipid status parameters and fibrinogen (p<0.001, p<0.01) were higher in women with higher CVRS. The most significant CVRS predictors in all PCOS women were SHBG, androstenedione, follicle-stimulating hormone (FSH) and dehydroepiandrosterone sulphate (DHEAS). ICO and all NAFLD indices exhibited significant positive correlation with CVRS and a model consisting of these indices provided good diagnostic accuracy (AUC>0.8) in identifying patients with increased cardiovascular risk (CVR). CONCLUSIONS Obesity is a higher risk for developing CVD than PCOS alone. Anthropometric parameters, lipid parameters, fibrinogen, NAFLD indices and ICO increase CVR in PCOS women. For the prediction of CVR in PCOS, we suggest a combination of NAFLD indices and ICO.

Abstract
OBJECTIVE To compare the prevalence of various metabolic and cardiovascular risk factors and insulin resistance between polycystic ovary syndrome (PCOS) patients with or without hyperandrogenism. MATERIAL AND METHODS This is a retrospective cross-sectional study involving women with PCOS as diagnosed according to the Androgen Excess (AE) Society definition (n=504) and women with normoandrogenemic PCOS (n=183). Anthropometrics, lipid profile, glucose, insulin, oral glucose tolerance test (OGTT), and reproductive hormone levels were evaluated. RESULTS Women with PCOS diagnosed according to the AE Society had a significantly higher prevalence of metabolic syndrome compared with the normoandrogenemic PCOS phenotype: odds ratio (OR) 2.95 [95% confidence interval (CI) 1.21-7.21]. There was no significant difference in the prevalence glucose intolerance test between the groups [OR: 2.15, 95% CI 0.71-6.56]. The prevalence of low high density lipoprotein (HDL)-cholesterol in the group under the AE-PCOS Society criteria was higher than that of the normoandrogenemic PCOS group [OR: 2.82, 95%CI 1.29-3.36]. CONCLUSION The risks of metabolic syndrome and cardiovascular disease may vary among the phenotypes of PCOS based on the Rotterdam criteria. This new data may be of reference in informing women with PCOS, although further prospective studies are needed to validate this proposition.

Abstract
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, alopecia, and acne. Cycle length >35 days suggests chronic anovulation, but cycle length slightly longer than normal (32 to 35 days) or slightly irregular (32 to 35-36 days) needs assessment for ovulatory dysfunction. Ovulatory dysfunction is associated with increased prevalence of endometrial hyperplasia and endometrial cancer, in addition to infertility. In PCOS, hirsutism develops gradually and intensifies with weight gain. In the neoplastic virilizing states, hirsutism is of rapid onset, usually associated with clitoromegaly and oligomenorrhea. Girls with severe acne or acne resistant to oral and topical agents, including isotretinoin (Accutane), may have a 40% likelihood of developing PCOS. Hair loss patterns are variable in women with hyperandrogenemia, typically the vertex, crown or diffuse pattern, whereas women with more severe hyperandrogenemia may see bitemporal hair loss and loss of the frontal hairline. Oral contraceptives (OCPs) can effectively lower androgens and block the effect of androgens via suppression of ovarian androgen production and by increasing sex hormone-binding globulin. Physiologic doses of dexamethasone or prednisone can directly lower adrenal androgen output. Anti-androgens can be used to block the effects of androgen in the pilosebaceous unit or in the hair follicle. Anti-androgen therapy works through competitive antagonism of the androgen receptor (spironolactone, cyproterone acetate, flutamide) or inhibition of 5α-reductase (finasteride) to prevent the conversion of T to its more potent form, 5α-dihydrotestosterone. The choice of antiandrogen therapy is guided by symptoms. The diagnosis of PCOS in adolescents is particularly challenging given significant age and developmental issues in this group. Management of infertility in women with PCOS requires an understanding of the pathophysiology of anovulation as well as currently available treatments. Many features of PCOS, including acne, menstrual irregularities, and hyperinsulinemia, are common in normal puberty. Menstrual irregularities with anovulatory cycles and varied cycle length are common due to the immaturity of the hypothalamic-pituitary-ovarian axis in the 2- to 3-year time period post-menarche. Persistent oligomenorrhea 2 to 3 years beyond menarche predicts ongoing menstrual irregularities and greater likelihood of underlying ovarian or adrenal dysfunction. In adolescent girls, large, multicystic ovaries are a common finding, so ultrasound is not a first-line investigation in women <17 years of age. Ovarian dysfunction in adolescents should be based on oligomenorrhea and/or biochemical evidence of oligo/anovulation, but there are major limitations to the sensitivity of T assays in ranges applicable to young girls. Metformin is commonly used in young girls and adolescents with PCOS as first-line monotherapy or in combination with OCPs and anti-androgen medications. In lean adolescent girls, a dose as low as 850 mg daily may be effective at reducing PCOS symptoms; in overweight and obese adolescents, dose escalation to 1.5 to 2.5 g daily is likely required. Anti-androgen therapy in adolescents could affect bone mass, although available short-term data suggest no effect on bone loss.

Abstract
Objective: The aim of this study was to investigate whether polycystic ovary syndrome (PCOS) phenotype without polycystic ovaries (PCO) differs in terms of in vitro fertilization (IVF) outcomes compared with classic phenotypes. Materials and Methods: This retrospective controlled study included 262 patients who underwent IVF treatment with an indication of unexplained or tubal factor infertility (control group), ovulatory patients with PCO morphology (group 1), PCOS phenotype with oligoanovulation and hyperandrogenemia (group 2), PCOS phenotype with PCO morphology and oligoanovulation (group 3). Outcomes and baseline characteristics of IVF-embryo transfer treatments were compared among all groups. Results: PCOS phenotype without PCO morphology had similar IVF stimulation characteristics compared with classic phenotypes; however, a higher total gonadotropin dose was needed to achieve similar results compared with patients with PCO morphology with or without PCOS. Basal follicle-stimulating hormone level (beta coefficient=0.207, p=0.003), group (beta coefficient=-0.305, p<0.001) and age (beta coefficient=0.311, p<0.001) were significantly associated with the total gonadotropin dose. The number of good quality embryo on transfer day was significantly lower in patients with isolated PCO morphology and PCO morphology with oligoanovulation than in those with PCOS phenotype without PCO morphology. Conclusion: PCO morphology provides easier stimulation, whereas hyperandrogenemia provides better results as good quality embryos. However, the end point is similar in terms of biochemical, clinical, and ongoing pregnancy rates.

Abstract
Intraovarian hyperandrogenism is one of the determining factors of follicular arrest in women with polycystic ovary syndrome (PCOS). Using androgenized rat models, we investigated the effects of androgens on metabolism, as well as on factors involved in follicular arrest and the reduced number of estrus cycles. The dihydrotestosterone (DHT)-treated rats had fewer estrus cycles, higher numbers of large arrested follicles and an increased in body weight gain compared with the dehydroepiandrostenedione (DHEA)- and placebo-treated rats. In cultured rat granulosa cells, DHT suppressed follicle stimulating hormone (FSH)-induced granulosa cell proliferation and increased the accumulation of cells in the G2/M phase. DHT decreased phosphorylated Akt (p-Akt) and cyclin D1 levels through increasing PTEN. DHT-promoted PTEN expression was regulated by peroxisome proliferator-activated receptor gamma (PPARγ) in granulosa cells. Meanwhile, in the large follicles of the DHT-treated rats, the expressions of PPARγ and PTEN were higher, but the expression of p-Akt and proliferating cell nuclear antigen (PCNA) were lower. Conclusively, DHT and DHEA produced differential effects on metabolism in prepubertal female rats like clinical manifestations of women with PCOS. DHT treatment may affect ovarian follicular maturation by altering granulosa cell proliferation through the regulation of enhancing PPARγ dependent PTEN/p-Akt expression in the granulosa cells.

Abstract
The aim of this study was to examine the external genital features in Turkish women with polycystic ovary syndrome (PCOS). Thirty-two newly diagnosed PCOS cases and 35 healthy women were included the study. All women underwent a thorough gynaecological examination. Clitoral length, and labia minora length and width were recorded. The groups were compared for features of external genital structures. Clitoral and labial lengths were significantly higher in PCOS group. There was a strong correlation between clitoral length and modified Ferriman-Gallwey score. The most effective predictor of PCOS was found to be clitoral length. Clitoral length alone predicted 99.9% of PCOS patients. There were some subclinical genital changes in women with PCOS. These changes in PCOS patients may be a sign of hyperandrogenism and might have diagnostic value in indistinct cases.

Abstract
CONTEXT Adrenal hyperandrogenism affects approximately 25% of polycystic ovary syndrome (PCOS) patients but its relation to obesity is not totally understood. OBJECTIVE This study aimed to assess dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) levels in relation to body mass index (BMI) in PCOS. DESIGN AND SETTING This was a prospective observational study at an institutional practice at an obstetrics/gynecology hospital. PARTICIPANTS The study included 136 PCOS patients, 20-35 years old, and 42 age-matched control women. The participants were classified with the BMI cutoff value of 27 kg/m(2) as follows: 1) high-BMI PCOS patients; 2) low-BMI PCOS patients; 3) high-BMI control women; and 4) low-BMI control women. The data were reanalyzed with the BMI cutoff value of 30 kg/m(2) to corroborate the findings in obese and nonobese patients. MAIN OUTCOME MEASURE(S) Blood samples were taken and LH, FSH, insulin, T, androstenedione (A4), DHEA, DHEAS, and glucose levels were determined. Homeostatic model assessment was calculated. Pelvic and abdominal ultrasound for ovarian morphology and adipose tissue, respectively, were performed. RESULTS Obese PCOS patients presented significantly more insulin resistance than nonobese PCOS patients. The LH levels and LH/FSH ratio were significantly higher in low-BMI than in high-BMI PCOS patients. The A4 and DHEAS levels were significantly higher in nonobese than in obese PCOS patients. A significant correlation between LH and A4 in nonobese PCOS patients was observed. The frequency of hyperandrogenism by increased A4, and DHEA along with DHEAS was significantly higher in low-BMI PCOS patients compared with high-BMI PCOS patients. Some findings observed with the BMI cutoff value of 27 kg/m(2) changed with the cutoff value of 30 kg/m(2). CONCLUSIONS Low BMI more so than high BMI is associated with increased LH, high A4, DHEA, and DHEAS levels in PCOS patients. The BMI cutoff value of 27 kg/m(2) classified better than 30 kg/m(2) for hormonal and metabolic characteristics.

Abstract
STUDY QUESTION What are the potential endocrine characteristics related to risk and severity of metabolic disturbances in women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWER Women with PCOS could be subtyped into four subgroups according to heterogeneous endocrine characteristics and the major predictive endocrine factors for metabolic aberrations among different subgroups were free androgen index (FAI) and luteinizing hormone (LH) levels. WHAT IS KNOWN ALREADY Women diagnosed with PCOS present with highly heterogeneous phenotypes, including endocrine and metabolic aberrations. Different strategies have been proposed to predict the metabolic outcomes but whether the endocrine factors can solely predict the metabolic aberrations is still inconclusive. STUDY DESIGN, SIZE, DURATION A cross-sectional study including 460 patients recruited from a reproductive endocrinology outpatient clinic of a tertiary medical center. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients with PCOS diagnosed according to the 2003 Rotterdam criteria were studied. Clinical history recorded by questionnaires, anthropometric measurements, biochemistry tests after an overnight fast, and pelvic ultrasonography were collected from all patients. MAIN RESULTS AND THE ROLE OF CHANCE Applying a matrix visualization and clustering approach (generalized association plots), the patients were divided into four distinct clusters according to the correlation with four endocrine parameters. Each cluster exhibited specific endocrine characteristics and the prevalence of metabolic syndrome (MS) was significantly different among the clusters (P < 0.0001). The high-risk subgroups for MS included one cluster with higher mean (SD) FAI (39.6 (14.7) in cluster 4), and another one with lower mean (SD) FAI (10 (6.4) in cluster 2). A common endocrine characteristic of these two metabolically unhealthy clusters was relatively lower LH level. Contrarily, higher LH level (≧15 mIU/ml) during early follicular phase was found to be the best indicator of the metabolically healthy cluster (cluster 1). While high FAI level did correlate with more severe metabolic aberrations, high LH level showed better predictive value than low FAI level to become a metabolically healthy cluster. LIMITATIONS, REASONS FOR CAUTION The results should be applied to other populations with caution due to racial or environmental differences. Another limitation is a lack of normal non-PCOS control in our study. WIDER IMPLICATIONS OF THE FINDINGS Stratifying women with PCOS into meaningful subtypes could provide a better understanding of related risk factors and potentially enable the design and delivery of more effective screening and treatment intervention. STUDY FUNDING/COMPETING INTERESTS This study was supported by grant NSC 100-2314-B002-027-MY3 from the National Science Council of Taiwan. TRIAL REGISTRATION NUMBER Nil.

Abstract
Approximately 20-30% of PCOS women demonstrate excess adrenal precursor androgen (APA) production, primarily using DHEAS as a marker of APA in general and more specifically DHEA, synthesis. The role of APA excess in determining or causing PCOS is unclear, although observations in patients with inherited APA excess (e.g., patients with 21-hydroxylase deficient congenital classic or non-classic adrenal hyperplasia) demonstrate that APA excess can result in a PCOS-like phenotype. Inherited defects of the enzymes responsible for steroid biosynthesis, or defects in cortisol metabolism, account for only a very small fraction of women suffering from hyperandrogenism or APA excess. Rather, women with PCOS and APA excess appear to have a generalized exaggeration in adrenal steroidogenesis in response to ACTH stimulation, although they do not have an overt hypothalamic-pituitary-adrenal axis dysfunction. In general, extra-adrenal factors, including obesity, insulin and glucose levels, and ovarian secretions, play a limited role in the increased APA production observed in PCOS. Substantial heritabilities of APAs, particularly DHEAS, have been found in the general population and in women with PCOS; however, the handful of SNPs discovered to date account only for a small portion of the inheritance of these traits. Paradoxically, and as in men, elevated levels of DHEAS appear to be protective against cardiovascular risk in women, although the role of DHEAS in modulating this risk in women with PCOS remains unknown. In summary, the exact cause of APA excess in PCOS remains unclear, although it may reflect a generalized and inherited exaggeration in androgen biosynthesis of an inherited nature.

Methods We analyzed the association between androstenedione, testosterone, and free testosterone and metabolic parameters in a cross-sectional study including 706 polycystic ovary syndrome and 140 BMI-matched healthy women. Polycystic ovary syndrome women were categorized into 4 groups: normal androstenedione and normal free testosterone (NA/NFT), elevated androstenedione and normal free testosterone (HA/NFT), normal androstenedione and elevated free testosterone (NA/HFT), elevated androstenedione and free testosterone (HA/HFT). Results Polycystic ovary syndrome women with elevated free testosterone levels (HA/HFT and NA/HFT) have an adverse metabolic profile including 2 h glucose, HbA1c, fasting and 2 h insulin, area under the insulin response curve, insulin resistance, insulin sensitivity index (Matsuda), triglycerides, total and high density lipoprotein cholesterol levels compared to NA/NFT (p<0.05 for all age- and BMI-adjusted analyses). In binary logistic regression analysis adjusted for age and BMI, odds ratio for insulin resistance was 2.78 (1.34–5.75, p = 0.006) for polycystic ovary syndrome women with HA/HFT compared to NA/NFT. We found no significantly increased risk of metabolic disorders in polycystic ovary syndrome women with HA/NFT. In multiple linear regression analyses (age- and BMI-adjusted), we found a significant negative association between androstenedione/free testosterone-ratio and area under the insulin response curve, insulin resistance, and total cholesterol/high density lipoprotein cholesterol-ratio and a positive association with Matsuda-index, and high density lipoprotein cholesterol (p<0.05 for all). Conclusions Polycystic ovary syndrome women with elevated free testosterone levels but not with isolated androstenedione elevation have an adverse metabolic phenotype. Further, a higher androstenedione/free testosterone-ratio was independently associated with a beneficial metabolic profile.

Abstract
BACKGROUND The present study was aimed to investigate lipid profile in relation to anthropometric indices and insulin resistance in overweight or obese women with polycystic ovary syndrome (PCOS). METHODS In this cross-sectional study, lipid profile and anthropometric indices including body mass index (BMI), waist and hip circumference, waist to hip ratio (WHR), and waist to height ratio (WHtR) were evaluated in 63 overweight or obese PCOS patients subdivided into insulin-resistant (IR) and non insulin-resistant (NIR) groups. IR was defined as homeostasis model of insulin resistance (HOMA-IR) ≥3.8. RESULTS Fasting insulin concentration and HOMA-IR were higher (P<0.001) and high-density lipoprotein cholesterol (P=0.012) was lower in IR group. All of the anthropometric measures other than WHR and BMI showed significant correlations with several lipid parameters. Amongst, WHtR showed the strongest correlation with total cholesterol (TC) (r=0.37; P=0.004) and low density lipoprotein cholesterol (LDL-C) (r=0.33; P=0.011) in the whole PCOS patients. CONCLUSION Anthropometric characteristics (especially BMI and hip circum-ference) are more important parameters correlated to lipid profile than IR in overweight or obesePCOS patients, confirming the importance of early treat-ment of obesity to prevent dyslipidemia in the future.

Abstract
CONTEXT Because of the elevated dehydroepiandrosterone sulfate (DHEAS) levels in polycystic ovary syndrome (PCOS) and the heritability of DHEAS serum levels, genes encoding the enzymes that control the sulfation of dehydroepiandrosterone (DHEA) to DHEAS and vice versa are obvious candidate genes to explain part of the heritability of PCOS. OBJECTIVE The objective of the study was to determine the role of genetic variants in sulfotransferase (SULT2A1), 3-phosphoadenosine 5-phosphosulfate synthase isoform 2 (PAPSS2), and steroid sulfatase (STS) in PCOS and in hormone levels related to the hyperandrogenic phenotype of PCOS. DESIGN This was a candidate-gene study. PATIENTS The discovery set consisted of 582 patients and 2017 controls. MAIN OUTCOME MEASURES A pruned subset of 28 single-nucleotide polymorphisms (SNPs) in SULT2A1, PAPSS2, and STS was generated based on pairwise genotypic correlation. Association with PCOS was tested, and we studied whether the SNPs modulate DHEAS levels, DHEA levels, and their ratio in PCOS. Significant SNPs were replicated in an independent sample of patients. RESULTS None of the SNPs in SULT2A1, PAPSS2, and STS constituted risk alleles for PCOS. SNP rs2910397 in SULT2A1 decreased the DHEAS to DHEA ratio in PCOS by 5% in the discovery sample. Meta-analysis of discovery and replication sample resulted in a combined effect of -0.095 (P = .027). However, carrying the minor T allele did not contribute to differences in the hyperandrogenic phenotype, including the levels of T and androstenedione, of PCOS patients. CONCLUSIONS Genetic variants in SULT2A1, PAPSS2, and STS do not predispose to PCOS. Although a variant in SULT2A1 decreased the DHEAS to DHEA ratio, no changes in other androgenic hormone levels were observed.

Abstract
Background Adrenal androgen excess is frequently observed in PCOS. The aim of the study was to determine whether adrenal gland function varies among PCOS phenotypes, women with hyperandrogenism (H) only and healthy women. Methods The study included 119 non-obese patients with PCOS (age: 22.2 ± 4.1y, BMI:22.5 ± 3.1 kg/m2), 24 women with H only and 39 age and BMI- matched controls. Among women with PCOS, 50 had H, oligo-anovulation (O), and polycystic ovaries (P) (PHO), 32 had O and H (OH), 23 had P and H (PH), and 14 had P and O (PO). Total testosterone (T), SHBG and DHEAS levels at basal and serum 17-hydroxprogesterone (17-OHP), androstenedione (A4), DHEA and cortisol levels after ACTH stimulation were measured. Results T, FAI and DHEAS, and basal and AUC values for 17-OHP and A4 were significantly and similarly higher in PCOS and H groups than controls (p < 0.05 for all) whereas three groups did not differ for basal or AUC values of DHEA and cortisol. Three hyperandrogenic subphenotypes (PHO, OH, and PH) compared to non-hyperandrogenic subphenotype (PO) had significantly and similarly higher T, FAI, DHEAS and AUC values for 17-OHP, A4 and DHEA (p < 0.05). All subphenotypes had similar basal and AUC values for cortisol. Conclusion PCOS patients and women with H only have similar and higher basal and stimulated adrenal androgen levels than controls. All three hyperandrogenic subphenotypes of PCOS exhibit similar and higher basal and stimulated adrenal androgen secretion patterns compared to non-hyperandrogenic subphenotype.

Abstract
The aim of this study was to examine the effect of adrenal versus ovarian androgen (dehydroepiandrosterone sulfate/total testosterone [DHEAS/TT]) on clinical presentation and related metabolic disturbances in Turkish women with polycystic ovarian syndrome (PCOS). Two hundred eighty PCOS cases were taken into the study. For all cases, the DHEAS/TT ratio was calculated. The median value of this ratio was 4.40. Patients with an androgen ratio lower than 4.40 were included in Group 1 and cases with a ratio higher than 4.40 were Group 2. The two groups were compared in terms of hormonal, biochemical and clinical parameters. Body mass index and waist circumference were lower, the Ferriman-Gallwey score was higher and the cycle length was shorter in Group 2. High DHEAS level was associated with better lipid profiles and lower levels of inflammatory markers, meaning good metabolic control in these women, in spite of increased hirsutism rates. In patients with PCOS, both androgens are usually high in proportion to each other. Therefore, it would be more meaningful to use the DHEAS/TT ratio for an assessment of the metabolic and phenotypic effects of PCOS.

Abstract
STUDY QUESTION What is the role of myostatin and its relationship with obesity, androgens and follistatin levels in women with polycystic ovary syndrome (PCOS)? SUMMARY ANSWERS: The myostatin level was positively correlated to the risk of abdominal obesity, but negatively associated with circulating levels of dehydroepiandrosterone sulfate (DHEAS) and follistatin in women with PCOS. WHAT IS KNOWN AND WHAT THIS PAPER ADDS Myostatin is a well-known negative regulator of skeletal muscle and is involved in metabolism; however, little is known about the role of myostatin in women with PCOS. In this study, we found that the myostatin level was positively related to the risk of abdominal obesity, but negatively related to the circulating levels of DHEAS and follistatin in women with PCOS. Such a relationship might imply a potential regulatory role of androgens and follistatin in the metabolism of skeletal muscle in women with PCOS. DESIGN A cross-sectional case-control study. PARTICIPANTS AND SETTING A total of 239 untreated, consecutive women with PCOS and 38 healthy volunteer women without PCOS were enrolled and studied in a tertiary medical center. MAIN RESULTS AND THE ROLE OF CHANCE Myostatin level was higher in women with PCOS than those without PCOS (16.6±15.6 and 14.2±9.7, P=0.025), but were not significantly different between non-obese women with and without PCOS after considering the effect of obesity (P=0.09). Stepwise multivariate regression analysis in women revealed that only the presence of PCOS (β=0.256, P=0.0001), total testosterone (β=0.159, P=0.031), DHEAS (β=-0.188, P=0.0003) and follistatin (β=-0.171, P=0.0001) levels were left in the final model and were significantly related to the myostatin level after considering all the explanatory variables. By using stepwise multivariate regression analysis, the total testosterone levels (β=0.196, P=0.003) were positively, but the DHEAS (β=-0.196, P<0.0001) and follistatin (β=-0.151, P=0.0001) levels were negatively, related to myostatin levels in women with PCOS after adjustment for age, anthropometric measurements, insulin sensitivity index and hormonal profiles. The high myostatin level was associated with the increased risk of abdominal obesity after further adjusting the androgens and follistatin levels in women with PCOS. LIMITATION, REASONS FOR CAUTION This study is a cross-sectional case-control design, and therefore, cannot answer the cause-effect relationship among the androgens, follistatin and myostatin levels. The small sample size and non-obese control group may also limit the application of the conclusion of the present study to general population other than women with PCOS. In addition, lack of data regarding muscle mass is another limitation in this study that prevents clarification of the relationship between myostatin, lean mass and obesity and therefore restricts the clinical application of the results. WIDER IMPLICATIONS OF THE FINDINGS Future studies to investigate the efficacy of exercise and lifestyle modification in treating women with PCOS should consider the myostatin, follistatin and androgen levels as well as the effect of muscle mass and BMI. STUDY FUNDING/COMPETING INTEREST This study was supported by grants NSC97-2314-B002-079-MY3, NSC98-2314-B002-105-MY3 and NSC 100-2314-B002-027-MY3 from the National Science Council of Taiwan.

Abstract
Polycystic ovary syndrome (PCOS) is a common disorder in women of reproductive age, affecting around 10% of them. Polycystic ovary syndrome is considered to be related to increased risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). There are 2 definitions for PCOS: one adopted in 1990 (classical PCOS with phenotypes A and B) and the other in 2003 (Rotterdam criteria with 4 phenotypes A to D). The latter is a wider definition including the 1990 phenotypes. There is mounting data suggesting that phenotypes C and D are not actually related to increased CVD risk, and thus screening for CVD risk factors of intervening for primary CVD prevention in young women is not cost-effective. There is an increasing number of suggestions to return to the 1990 criteria plus some metabolic parameters to identify real CVD risk in this population. However, such a strategy needs verification by large, prospective studies.

Abstract
OBJECTIVE To perform a review and metaanalysis of the studies evaluating the status of serum inflammatory markers in women with polycystic ovary syndrome (PCOS). DESIGN Systematic review and metaanalysis of articles published in English before January 2010 and identified using the PubMed search engine. SETTING Academic hospital. PATIENT(S) Women with PCOS and appropriate controls. INTERVENTION(S) Measurement of serum concentrations of inflammatory markers by high-sensitivity techniques. MAIN OUTCOME MEASURE(S) Metaanalyses of the mean difference in serum C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) concentrations among patients with PCOS and appropriate controls, applying random-effects models to limit interstudy variability, and using appropriate estimates of evidence dissemination bias. RESULT(S) Metaanalysis of the 31 articles meeting inclusion criteria showed that circulating CRP was 96% higher in women with PCOS compared to controls (95% confidence interval, 71%-122%; z = 7.32) without evidence of dissemination bias (Egger's regression intercept, 0.45; 95% confidence interval, -2.30 to 3.21). These findings persisted after excluding five studies with mismatches in body mass, frequency of obesity, or both, between women with PCOS and controls. Metaanalyses involving 10 studies of IL-6, and nine studies of TNF-α revealed no statistically significant differences between PCOS and controls. CONCLUSION(S) Women with PCOS exhibit an elevation in circulating CRP that is independent of obesity. This finding corroborates existing molecular evidence of the chronic low-grade inflammation that may underpin the pathogenesis of this disorder.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) are known to have high prevalence of acne and elevated androgen levels. The current study aims to determine if dehydroepiandrosterone sulfate (DHEAS) level is associated with the presence of acne and reduced risk of abdominal obesity in women with PCOS, after considering the concurrent high testosterone level and insulin resistance (IR). METHODS Three hundred and eighteen untreated consecutive Taiwanese women with PCOS were enrolled. Phenotypic hyperandrogenism was recorded, and BMI, waist circumference, waist-to-hip ratio, lipid profiles, fasting glucose and insulin levels and hormone profiles were measured. RESULTS Women with acne were younger, had higher serum DHEAS levels (6.01 ± 3.45 versus 4.87 ± 2.49 μmol/l, P = 0.002) and a lower BMI (P = 0.0006), but comparable serum testosterone levels, in comparison with women without acne. The aggravating effect of elevated DHEAS on the risk of acne (odds ratio = 2.15, 95% confidence interval: 1.25-3.68, P = 0.005 for DHEAS cut-off of 6.68 μmol/l) still exited after adjustment for age and BMI. The DHEAS level was positively correlated with the testosterone level, but inversely related to waist circumference, waist-to-hip ratio, BMI, IR index, low-density lipoprotein-cholesterol and triglycerides. Women with PCOS in the highest quartile of DHEAS had the lowest risk of abdominal obesity after adjustment for age, IR, dyslipidemia, testosterone and estradiol levels. CONCLUSIONS Our results demonstrated the high serum DHEAS in women with PCOS was associated with the presence of acne and a significantly reduced risk of abdominal obesity, independent of serum testosterone concentration and IR.

Abstract
In all hirsute women, a careful diagnostic evaluation should be performed, and the findings will largely influence the therapeutic decisions and the follow-up of the patients. An assay of serum 17-OH progesterone is needed, while the measurement of total testosterone and sex hormone-binding globulin, with the calculation of free androgen index, are useful to assess androgen secretion. Other tests should be suggested only according to responses of specific clinical questions. Owing to their high cardiovascular and metabolic risk, patients with polycystic ovary syndrome should have an oral glucose-tolerance test and a complete lipid profile. No ideal treatment for hirsutism exists but, with careful combination of pharmacological treatments and direct hair removal, it is generally possible to obtain a prolonged improvement of hirsutism.

Abstract
PURPOSE OF REVIEW Polycystic ovary syndrome (PCOS) is a common complex endocrine genetic disorder, which involves overproduction of androgens, leading to heterogeneous range of symptoms and associated with increased metabolic and cardiovascular morbidity. This review focuses on androgen biosynthesis, use, metabolism in PCOS and clinical consequences of hyperandrogenism. RECENT FINDINGS Controversial definition of the disorder and different phenotypic subgroups present a challenge for clinical and basic research. Further investigation of different phenotypes highlights the fact that PCOS probably represents a group of disorders with different etiologies. Prenatal androgen exposure and adolescent studies suggest early in life androgen excess as initiating factor of PCOS, but insufficient evidence available to confirm this hypothesis. Various intracellular signaling pathways implicated in PCOS steroidogenesis and in androgen action have been studied, however, PCOS pathogenesis remains obscure. Growing evidence links androgens with pathophysiology of PCOS and metabolic derangements. SUMMARY Despite intensive investigation, etiology and underlying mechanisms of PCOS remain unclear, warranting further investigation. Better understanding of molecular and genetic basis might lead to invention of novel therapeutic approaches. Long-term interventional studies that lower androgen levels in women with hyperandrogenism might protect against metabolic and cardiovascular comorbidities are needed.

Abstract
OBJECTIVE To determine the effect of serum androgens [testosterone and dehydroepiandrosterone sulphate (DHEAS)] on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. STUDY DESIGN This observational (cross sectional) study was conducted on 53 consecutive infertile women undergoing IVF cycles in an academic infertility clinic between September 2006 and August 2007. Basal testosterone and DHEAS were measured and on third day of IVF cycle and on 14th day of embryo transfer these values were re-checked. Serum beta-hCG analysis was done 12 days after embryo transfer and ultrasound scan was scheduled 2 weeks later. RESULTS Testosterone level was significantly elevated in pregnant women on 14th day of embryo transfer (p < 0.001). Testosterone and DHEAS concentrations on third day of IVF cycle and DHEAS concentration 2 weeks after embryo transfer had not significant correlation with IVF success, but mean androgens concentrations were higher in pregnant group. CONCLUSION Serum testosterone concentration on 14th day of embryo transfer can predict successful IVF cycles, so with regulating androgen levels, improved pregnancy rates can be expected.

Abstract
The origin of circulating DHEA and adrenal-derived androgens in humans and nonhuman primates is largely distinct from other mammalian species. In humans and many Old world primates, the fetal adrenal gland and adult zona reticularis (ZR) are known to be the source for production of DHEA (and DHEAS) in mg quantities. In spite of similarities there are also some differences. Herein, we take a comparative endocrine approach to the diversity of adrenal androgen biosynthesis and its developmental timing in three primate species to illustrate how understanding such differences may provide unique insight into mechanisms underlying adrenal androgen regulation and its pathophysiology in humans. We contrast the conventional developmental onset of adrenal DHEA biosynthesis at adrenarche in humans with (1) an earlier, peri-partutrition onset of adrenal DHEA synthesis in rhesus macaques (Old World primate) and (2) a more dynamic and reversible onset of adrenal DHEA biosynthesis in female marmosets (New World primate), and further consider these events in terms of the corresponding developmental changes in expression of CYP17, HSD3B2 and CYB5 in the ZR. We also integrate these observations with recently described biochemical characterization of CYP17 cDNA cloned from each of these nonhuman primate species and the corresponding effects of phosphorylation versus CYB5 coexpression on 17,20 lyase versus 17-hydroxylase activity in each case. In addition, female rhesus macaques exposed in utero to exogenous androgen excess, exhibit symptoms of adrenal hyperandrogenism in adult females in a manner reminiscent of that seen in the human condition of PCOS. The possible mechanisms underlying such adrenal hyperandrogenism are further considered in terms of the effects of altered relative expression of CYP17, HSD3B2 and CYB5 as well as the altered signaling responses of various kinases including protein kinase A, or the insulin sensitive PI3-kinase/AKT signaling pathway which may impact on 17,20 lyase activity. We conclude that while the triggers for the onset of ZR function in all three species show clear differences (age, stage of development, social status, gender), there are still common mechanisms driving an increase in DHEA biosynthesis in each case. A full understanding of the mechanisms that control 17,20 lyase function and dysfunction in humans may best be achieved by comparative studies of the endocrine mechanisms controlling adrenal ZR function and dysfunction in these nonhuman primate species.

Abstract
Adrenal androgen excess is found in adult female rhesus monkeys previously exposed to androgen treatment during early gestation. In adulthood, such prenatally androgenized female monkeys exhibit elevated basal circulating levels of dehydroepiandrosterone sulfate (DHEAS), typical of polycystic ovary syndrome (PCOS) women with adrenal androgen excess. Further androgen and glucocorticoid abnormalities in PA female monkeys are revealed by acute ACTH stimulation: DHEA, androstenedione and corticosterone responses are all elevated compared to responses in controls. Pioglitazone treatment, however, diminishes circulating DHEAS responses to ACTH in both prenatally androgenized and control female monkeys, while increasing the 17-hydroxyprogesterone response and reducing the DHEA to 17-hydroxyprogesterone ratio. Since 60-min post-ACTH serum values for 17-hydroxyprogesterone correlate negatively with basal serum insulin levels (all female monkeys on pioglitazone and placebo treatment combined), while similar DHEAS values correlate positively with basal serum insulin levels, circulating insulin levels may preferentially support adrenal androgen biosynthesis in both prenatally androgenized and control female rhesus monkeys. Overall, our findings suggest that differentiation of the monkey adrenal cortex in a hyperandrogenic fetal environment may permanently upregulate adult adrenal androgen biosynthesis through specific elevation of 17,20-lyase activity in the zona fasciculata-reticularis. As adult prenatally androgenized female rhesus monkeys closely emulate PCOS-like symptoms, excess fetal androgen programming may contribute to adult adrenal androgen excess in women with PCOS.
