Decreased Serum Level of Gamma-amino Butyric Acid in Egyptian Infertile Females with Polycystic Ovary Syndrome is Correlated with Dyslipidemia, Total Testosterone and 25(OH) Vitamin D Levels. J Med Biochem 2019; 38:512-518. [PMID: 31496917 PMCID: PMC6708297 DOI: 10.2478/jomb-2018-0051] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Accepted: 12/26/2018] [Indexed: 02/06/2023] Open
Abstract
Background Polycystic ovary syndrome (PCOS) is one of the most common female endocrine disorders around the world. Increasing evidence suggests that neurotransmitter Gamma-aminobutyric acid (GABA) is involved in the pathogenesis of PCOS through its central role in the hypothalamus. However, the peripheral role of GABA in PCOS has not been sufficiently investigated in spite of its existence in peripheral organs. First, the aim of this study is to, investigate serum GABA level in Egyptian PCOS patients. Second, to explore the correlation between serum GABA level with Body Mass Index (BMI), dyslipidemia, totaltestosterone and 25 (OH) vitamin D. Methods Eighty PCOS patients and eighty age-matched healthy females were included in this study. All parameters were assessed colourimetrically or with ELISA. Results PCOS patients exhibited significantly decreased serum GABA level compared to controls (p < 0.001). There was a significant positive correlation between serum GABA and 25(OH) vitamin D levels (r = 0.26, p = 0.018), and a significant negative correlation with total testosterone (r = - 0.3, p = 0.02), total cholesterol (TC) (r = - 0.31, p = 0.01) and LDL-Cholesterol (LDL-C) (r = - 0.23, p = 0.045), respectively. Conclusions The findings of this study suggest that disrupted GABA level in the peripheral circulation is an additional contributing factor to PCOS manifestations. GABA deficiency was correlated with 25 (OH) vitamin D deficiency, dyslipidemia, and total testosterone. Further investigations for GABA adjustment might provide a promising means for better management of PCOS symptoms.

Abstract
OBJECTIVES To evaluate the effects of oral contraceptive pill (OCP) and metformin at the end of 6 months of treatment on ovarian stromal blood flow by using pulsed and color Doppler in women with PCOS. METHODS Women with PCOS (n=101) fulfilling the Rotterdam criteria were enrolled and randomized to receive either OCP or metformin. OCP was administered in cycles of 28 days (21 pills containing 35μg of ethinylestradiol plus 2mg of cyproterone acetate followed by 7 placebo pills) for six cycles and metformin 500mg was administered twice daily for 6 months. Clinical, anthropometric, hormonal and metabolic parameters and resistance index (RI) and pulsatility index (PI) of both ovarian stromal vessels were assessed before and after treatment. RESULTS OCP resulted in a higher reduction in serum luteinizing hormone (LH) and androgens whereas metformin resulted in significant reduction in BMI, waist circumference, and insulin resistance. There was a significant increase in RI and PI of both ovarian stromal vessels with both drugs post-treatment, however, the increase was more prominent in the OCP group. There was a significant negative correlation between changes in LH and testosterone levels with changes in PI and RI in OCP group whereas changes in serum fasting insulin levels negatively correlated with changes in PI and RI values in the Metformin group. CONCLUSIONS Treatment with both OCP and metformin leads to a reduction in ovarian stromal vascularization in PCOS women perhaps through different mechanisms and this reduction is more prominent with OCP.

Abstract
Gonadotropin-releasing hormone (GnRH) modulators are widely used in numerous reproductive conditions including infertility. Several clinical studies showed mixed results regarding the efficacy of GnRH modulators in patients with polycystic ovary syndrome (PCOS). Along with this, few preclinical studies focus on the effect of GnRH modulators in PCOS-induced animals. Therefore, the present study was designed to study the effect of leuprolide and cetrorelix on hormonal, metabolic, and menstrual dysfunction PCOS rats. Prepubertal female rats were divided into four groups: Group I received a normal pellet diet and Groups II, III, and IV received 40% high-fat diet for 105 days. Similarly, adult female rats were divided into four groups: Group I received 1% carboxymethylcellulose (CMC) and Groups II, III, and IV received letrozole (1 mg/kg, per oral [p.o.] in 1% CMC) for 21 days. Thereafter, leuprolide (2.5 µg/rat, s.c.) and cetrorelix (10 µg/kg, subcutaneous [s.c.]) treatment were given to Group III and Group IV animals, respectively, for 21 days. Oral glucose tolerance test, lipid profile, fasting glucose, insulin, estrus cycle, hormonal profile, ovary weight, ovarian histopathological changes, and LHR and FSHR expressions were measured. Treatment with leuprolide and cetrorelix did not improve glucose intolerance, insulin level, insulin sensitivity indices, sex hormone levels, lipid profile, and estrus cycle. Only testosterone level, total cholesterol level, and follicular development were improved. Therefore, it was concluded that both leuprolide and cetrorelix showed improvement in follicular development, which could be helpful for improving fertility in PCOS.

Abstract
Objectives It has been suggested that the symptoms of Polycystic Ovary Syndrome (PCOS) could be improved by resistance training. Design This review focuses on identifying studies that use resistance training to examine how it can affect the symptoms of polycystic ovary syndrome (PCOS). Methods Medline, Cochrane, Dare and PubMed databases were searched to find relevant articles. All studies were assessed in terms of their design and methods. Results We found 10 studies that used resistance training to examine how it affects the symptoms of PCOS. Conclusions There is a need for further investigation. Most studies that examine the effects of resistance training on the symptoms of PCOS needed to consider the diet (macronutrient) of the participants along with the resistance training to have a better picture of how resistance training can affect the PCOS symptoms. Many questions are still unanswered.

Abstract
Polycystic ovary syndrome (PCOS) is a common condition, affecting 5⁻10% of women of reproductive age worldwide. It has serious reproductive implications and causes mood disorders and metabolic disorders, such as type-2 diabetes. Because PCOS reflects multiple abnormalities, there is no single drug that can treat all its symptoms. Existing pharmaceutical agents, such as oral contraceptives (OCs), are suggested as a first-line therapy for menstrual irregularities; however, OCs are not appropriate for women pursuing pregnancy. Additionally, insulin-sensitizing agents, which appear to decrease insulin levels and hyperandrogenemia in women with PCOS, have been associated with a high incidence of gastrointestinal adverse effects. It is a common practice in Chinese society to receive traditional Chinese medicine (TCM) for treatment of gynecological problems and infertility. Current research demonstrates that several herbs and herbal formulas show beneficial effects in PCOS treatment. In this study, we conducted the first large-scale survey through the Taiwan National Health Insurance Program database to analyze TCM utilization patterns among women with PCOS in Taiwan during 1997⁻2010. The survey results revealed that 89.22% women with newly diagnosed PCOS had received TCM therapy. Jia-Wei-Xiao-Yao-San and Xiang-Fu (Rhizoma Cyperi) were the most commonly used formula and single herb, respectively, in the database. In addition, we found that the top five commonly prescribed single herbs and herbal formulas have shown promise in treating symptoms associated with PCOS.

Abstract
Core binding factor β (CBFβ) is a non-DNA-binding partner of all RUNX proteins and critical for transcription activity of CBF transcription factors (RUNXs/CBFβ). In the ovary, the expression of Runx1 and Runx2 is highly induced by the luteinizing hormone (LH) surge in ovulatory follicles, whereas Cbfb is constitutively expressed. To investigate the physiological significance of CBFs in the ovary, the current study generated two different conditional mutant mouse models in which granulosa cell expression of Cbfb and Runx2 was reduced by Cre recombinase driven by an Esr2 promoter. Cbfbgc-/- and Cbfbgc-/- × Runx2gc+/- mice exhibited severe subfertility and infertility, respectively. In the ovaries of both mutant mice, follicles develop normally, but the majority of preovulatory follicles failed to ovulate either in response to human chorionic gonadotropin administration in pregnant mare serum gonadotropin-primed immature animals or after the LH surge at 5 months of age. Morphological and physiological changes in the corpus luteum of these mutant mice revealed the reduced size, progesterone production, and vascularization, as well as excessive lipid accumulation. In granulosa cells of periovulatory follicles and corpora lutea of these mice, the expression of Edn2, Ptgs1, Lhcgr, Sfrp4, Wnt4, Ccrl2, Lipg, Saa3, and Ptgfr was also drastically reduced. In conclusion, the current study provided in vivo evidence that CBFβ plays an essential role in female fertility by acting as a critical cofactor of CBF transcription factor complexes, which regulate the expression of specific key ovulatory and luteal genes, thus coordinating the ovulatory process and luteal development/function in mice.

Abstract
AbstractPolycystic ovary syndrome (PCOS) is one of the most common causes of infertility in women of reproductive age. Insulin resistance is a main pathophysiologic feature in these patients. According to some studies, the intake of probiotic bacteria may improve glucose homoeostasis. The aim of this study was to investigate the effect of synbiotics on metabolic parameters and apelin in PCOS patients. This randomised double-blind placebo-controlled trial was conducted on eighty-eight PCOS women aged 19–37 years old. The participants were randomly assigned to two groups receiving (1) synbiotic supplement (n44), and (2) placebo (n44) for 12 weeks. Fasting blood samples were taken at baseline and after 12 weeks. The two groups showed no difference in fasting blood sugar (adjusted mean difference: 0·60; 95 % CI −3·80, 5·00,P=0·727), plasma glucose fasting 2-h (adjusted mean difference 2·09; 95 % CI −9·96, 14·15,P=0·134), HbA1c (adjusted mean difference 0·06; 95 % CI −0·09, 0·22,P=0·959), homoeostatic model assessment-insulin resistance (HOMA-IR) (adjusted mean difference: 0·02; 95 % CI −0·99, 1·03,P=0·837), quantitative insulin sensitivity check index (QUICKI) (adjusted mean difference: −0·02; 95 % CI −0·33, 0·29,P=0·940) and C-reactive protein (CRP) (adjusted mean difference: 0·24; 95 % CI −1·61, 2·08,P=0·141) by the end of the intervention. A significant difference was observed in the mean apelin 36 before and after the intervention between synbiotic and placebo groups (adjusted mean difference: −4·05; 95 % CI −7·15, −0·96,P=0·004). A 12-week synbiotic supplementation has no significant beneficial effects on HOMA-IR and CRP in PCOS patients, whereas the level of apelin 36 significantly decreased.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting women of reproductive age manifesting with polycystic ovaries, menstrual irregularities, hyperandrogenism, hirsutism, and insulin resistance. The oligomenorrhea and amenorrhea characteristic to PCOS are associated with low bone mineral density (BMD); conversely, the hyperandrogenism and hyperinsulinemia may elicit a protective effect on BMD. As bone geometric properties provide additional information about bone strength, the objective of this study was to compare measures of hip geometry in women with PCOS to a healthy female population. Using dual-energy X-ray absorptiometry, BMD and measures of hip geometry were determined in women with PCOS (n = 60) and healthy controls (n = 60) aged 18-35 years. Clinical biochemical measures were also determined in women with PCOS. Measures of hip geometry, including cross-sectional area, cross-sectional moment of inertia, subperiosteal width (SPW), and section modulus, were similar between groups following correction for body mass index (BMI) (all p > 0.05) with intertrochanter SPW significantly lower in women with PCOS (p < 0.05). BMI-corrected whole body BMD as well as the lumbar spine and regions of proximal femur were also comparable between groups. In women with PCOS, BMI-corrected correlations were found between insulin and femoral shaft SPW (r = 0.322, p < 0.05), glucose and femoral neck (r = 0.301, p < 0.05), and trochanter BMD (0.348, p < 0.05), as well as between testosterone and femoral neck BMD (0.376, p < 0.05) and narrow neck cross-sectional area (0.306, p < 0.05). This study demonstrates that women with PCOS may have compromised intertrochanter SPW while oligomenorrhea appears to have no detrimental effect on bone density or geometry in women with PCOS.

Abstract
STUDY OBJECTIVE The objective of this study was to evaluate whether body weight status and clinical hyperandrogenism may influence social competencies and psychological gender features in adolescent girls. DESIGN AND PARTICIPANTS In 104 adolescent girls, psychological gender inventory (PGI) and social competencies questionnaire (SCQ) (assessing social abilities in three aspects: intimacy (I), social exposure (SE), and assertiveness (AS)) were performed. Subjects were divided into four subgroups: G1-24 nonobese girls without hyperandrogenism, G2-18 obese girls without hyperandrogenism, G3-30 nonobese hyperandrogenic girls, and G4-32 obese girls with hyperandrogenism. RESULTS There were no significant differences in all parts of SCQ and PGI between the study and control groups. The feminine woman type dominated in all groups; in G3 and G4, masculine woman type appeared more often than in G1 and G2 (13.3% and 12.5% versus 4.0% and 0.0%, resp.). In G4, positive relationship between BMI z-score and SCQ (r = 0.4, p = 0.03) was found. In G1, the relationship was opposite (r = -0.5, p = 0.03). Hirsutism correlated negatively with SCQ (r = -0.5, p = 0.02), I (r = -0.5, p = 0.02), and AS (r = -0.5, p = 0.02) only in G1; in other groups, this relationship was insignificant. In G4, higher testosterone level was associated with lower SCQ (r = -0.5, p = 0.008) and AS (r = -0.5, p = 0.003). In G2, testosterone concentration correlated positively with SCQ (r = 0.6, p = 0.01), SE (r = 0.5, p = 0.02), and AS (r = 0.6, p = 0.02). CONCLUSION In adolescent girls, neither body weight nor clinical features of hyperandrogenism seem to be the source of evaluated disorders in psychological functioning.

In vitro maturation (IVM) of human oocytes is an emerging treatment option for women with polycystic ovary/polycystic ovary syndrome (PCO/PCOS) in addition to the standard in vitro fertilization (IVF) treatment. There has been significant improvements in pregnancy rates with IVM over the last two decades. This article reviews the place of IVM for women with PCO/PCOS, placing an emphasis on the predictors of successful pregnancy, optimization of culture media, IVM protocols, pregnancy rates, and neonatal outcomes following IVM treatment.

Abstract
Polycystic ovary syndrome (PCOS) is a major endocrine disorder afflicting women of reproductive age. Women with PCOS are more likely to suffer from mental health disturbances than healthy women. The "infertility" suffered by PCOS patients would also lead to mental health disturbances. Symptom Checklist 90 (SCL-90) and questionnaire which includes patients' socio-economic and demographic data were used to assess the mental health status of PCOS (n=103) and non-PCOS (n=110) infertile patients. Logistic regression analysis and t-tests were used for comparative analysis. The data demonstrated that scores of depression, interpersonal sensitivity, obsessive-compulsive, and hostility symptoms in PCOS infertile patients were significantly higher than those in the non-PCOS infertile patients (P<0.05). Logistic regression analysis revealed that acne had negative effect on mental health status (P<0.05). Secondary infertile PCOS patients were more easily to suffer from somatization, interpersonal sensitivity, obsessive-compulsive, anxiety, hostility and paranoid ideation symptoms than the primary infertile PCOS patients (P<0.05). The results suggested that the PCOS patients especially the secondary infertile PCOS patients had obvious mental health disturbances. The acne might play an importance role in the occurrence of mental health disturbances in PCOS patients. PCOS related symptoms may be risk factors of mental health status in PCOS patients with infertility. More attention should be paid to the PCOS infertile patients, and mental health therapy should be considered if necessary.

Abstract
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.

Abstract
OBJECTIVE Metformin has been used as a treatment option for polycystic ovary syndrome (PCOS) since 1994; however, more than a hundred randomized clinical trials have reported controversial results regarding the efficacy of metformin in PCOS. This could be due to the small sample size and high variability in methodology between studies. The objective of the present meta-analysis was to determine the effect of metformin on clinical, metabolic, and endocrine outcomes compared to placebo in PCOS women. METHODS Randomized controlled trials evaluating the efficacy of metformin were identified using a literature search in PubMed. Bibliographies of relevant studies were also screened to identify additional studies. Data was extracted from included studies and analyzed using RevMan software 5.3 from the Cochrane Collaboration. MAIN OUTCOME MEASURES Clinical outcomes included body mass index, waist to hip ratio, systolic and diastolic blood pressure and Ferriman-Gallway score. Metabolic outcomes included total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, very low-density lipoprotein, fasting blood glucose, fasting insulin levels, glucose insulin ratio, HOMA-IR and QUICKI. Endocrine outcomes such as serum testosterone, free testosterone, free androgen index, serum sex hormone binding globulin, dehydroepiandrosterone sulfate, luteinizing hormone, follicle stimulating hormone, LH/FSH ratio, estradiol, and progesterone levels. CONCLUSION Metformin showed significant improvement in clinical outcomes but not in metabolic and endocrine outcomes in PCOS women; however, heterogeneity between studies was found to be moderate to high.

Abstract
The frequency of polycystic ovary syndrome (PCOS) and the consequent fertility disorders cause many difficulties in the management of the assisted reproductive technics. Some studies are focused on different additional treatments, stimulation protocols or techniques that could optimize the in vitro fertilization cycles. The quality of the oocytes and embryos of these patients is also an outstanding issue. They remain difficult to actually evaluate during management, and none of the few published studies on this subject demonstrated any inferiority, compared to control patients. However, many differences have been highlighted, studying intra- and extra-ovarian factors. The advent of new genetic techniques could allow a better understanding of the pathophysiological mechanisms of the syndrome, as well as refining the evaluation of oocytes and embryos, in order to better predict the results of in vitro fertilization attempts. Pregnancy and birth rates, however, appear to be comparable to those of the general population.

Abstract
Polycystic ovary syndrome (PCOS) is a common problem among Arab women and is the main cause of infertility due to anovulation. This study investigates insulin resistance (IR) and obesity in different PCOS phenotypes among infertile women (n = 213), of whom 159 had PCOS and 54 women without PCOS, recruited as a control group. Biometric, hormonal and clinical parameters were studied. IR was observed in 133 (83.6%) women with PCOS and in 25 (46.3%) women without PCOS (p < 0.001). IR was significantly associated with PCOS only among women with central obesity (χ2 = 35.0, p < 0.001) and not for the normal category (χ2 = 4.04, p < 0.058). The LH/FSH ratio was not significantly different among the PCOS group (n = 37, 23.3%) compared to the control group (n = 9, 16.7%) (p = 0.308). Among women with PCOS, the most common phenotype was type I (50.3%), with type III (29.6%), type II (14.5%) and type IV (5.7%). Type I had the highest values of fasting insulin (median = 12.98 mU/mL) and HOMA IR values (significant difference among the four phenotypes, p = 0.009 and 0.006, respectively) and is associated with severity of the disease. There was no difference in glucose levels.

Abstract
Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and the leading cause of anovulatory infertility. Characterised by hyperandrogenism, menstrual dysfunction and polycystic ovaries, PCOS is a broad-spectrum disorder unlikely to stem from a single common origin. Although commonly considered an ovarian disease, the brain is now a prime suspect in both the ontogeny and pathology of PCOS. We discuss here the neuroendocrine impairments present in PCOS that implicate involvement of the brain and review evidence gained from pre-clinical models of the syndrome about the specific brain circuitry involved. In particular, we focus on the impact that developmental androgen excess and adult hyperandrogenemia have in programming and regulating brain circuits important in the central regulation of fertility. The studies discussed here provide compelling support for the importance of the brain in PCOS ontogeny and pathophysiology and highlight the need for a better understanding of the underlying mechanisms involved.

Abstract
AIM: To investigate the association of peroxisome proliferator-activated receptor gamma (PPARG) Pro12Ala polymorphism with polycystic ovary syndrome (PCOS) and its effect on the metabolic parameters in PCOS women. METHODS: The study used PCR to identify the presence of the PPARG Pro12Ala polymorphism in 100 PCOS women and 120 age-matched healthy women. All participants were subjected to anthropometry, biochemical and metabolic evaluation. RESULTS: Significant difference in the genotypes distributions of PPARG Pro12Ala polymorphism was observed among PCOS women and controls (p = 0.03). The frequency of the polymorphic allele Ala was significantly higher in PCOS cases than that in the controls (OR = 2.01, p = 0.01). The carries of the variant allele Ala in PCOS women showed significant higher values in body mass index (BMI), systolic and diastolic blood pressure, waist circumference, waist to hip ratio, sum of skin folds, fasting blood glucose, fasting blood insulin, HOMA-IR, fasting triglycerides, total cholesterol and low-density lipoprotein than non-carriers. CONCLUSION: The PPARG Pro12Ala polymorphism might contribute to the risk of PCOS and abnormal metabolic parameters and could be considered as a biomarker for early diagnosis and clinic prediction of metabolic complications.

Abstract
The aim of the study is to investigate the molecular mechanism behind androgen reduction in porcine granulosa cells (pGCs) with Salvia miltiorrhiza Bunge extract cryptotanshinone. PGCs were isolated from porcine ovaries and identified. Androgen excess model of the pGCs was induced with the MAPK inhibitor PD98059 and then treated with cryptotanshinone. The testosterone level was measured by radioimmunoassay in the culture media. The protein levels of P-ERK1/2, c-Fos, and CYP17 in the cells were measured by western blot. Cryptotanshinone decreased the concentration of testosterone and the protein level of CYP17 and increased the protein levels of P-ERK1/2 and c-Fos in the androgen excess mode. After the c-Fos gene was silenced by infection with c-Fos shRNA lentivirus, we measured the mRNA expression by quantitative RT-PCR and protein level by western blot of P-ERK1/2, c-Fos, and CYP17. This showed that the mRNA expression and protein level of P-ERK1/2 and c-Fos were significantly reduced in the shRNA–c-Fos group compared to the scrambled group, while those of CYP17 were significantly increased. So we concluded that cryptotanshinone can significantly reduce the androgen excess induced by PD98059 in pGCs. The possible molecular mechanism for this activity is regulating the ERK/c-Fos/CYP17 pathway.

Abstract
The role of high fructose ingestion (HFI) in the development of conditions mimicking human metabolic syndrome has mostly been demonstrated in male animals; however, the extent of HFI-induced metabolic alterations in females remains unclear. The present study investigated whether HFI-induced metabolic perturbations differ between sexes and whether HFI aggravates the metabolic disturbances under ovarian hormone deprivation. Male, female, and ovariectomized (OVX) Sprague-Dawley rats were given either water or liquid fructose (10% wt/vol) for 6 wk. Blood pressure, glucose tolerance, insulin-stimulated glucose transport activity and signaling proteins, including insulin receptor (IR), insulin receptor substrate 1 (IRS-1), Akt, Akt substrate of 160 kDa (AS160), AMPKα, JNK, p38 MAPK, angiotensin-converting enzyme (ACE), ANG II type 1 receptor (AT1R), ACE2, and Mas receptor (MasR) in skeletal muscle, were evaluated. We found that HFI led to glucose intolerance and hypertension in male and OVX rats but not in female rats with intact ovaries. Moreover, HFI did not induce insulin resistance in the skeletal muscle of female and OVX rats but impaired the insulin-stimulated glucose transport activity in the skeletal muscle of male rats, which was accompanied by lower insulin-stimulated IRS-1 Tyr989 (44%), Akt Ser473 (30%), and AS160 Ser588 (43%), and increases in insulin-stimulated IRS-1 Ser307 (78%), JNK Thr183/Tyr185 (69%), and p38 MAPK Thr180/Tyr182 (81%). The results from the present study show sex differences in the development of metabolic syndrome-like conditions and indicate the protective role of female sex hormones against HFI-induced cardiometabolic abnormalities.

Abstract
Polycystic ovary syndrome (PCOS) is a prevalent and distressing endocrine disorder lacking a clearly identified aetiology. Despite its name, PCOS may result from impaired neuronal circuits in the brain that regulate steroid hormone feedback to the hypothalamo-pituitary-gonadal axis. Ovarian function in all mammals is controlled by the gonadotropin-releasing hormone (GnRH) neurons, a small group of neurons that reside in the pre-optic area of the hypothalamus. GnRH neurons drive the secretion of the gonadotropins from the pituitary gland that subsequently control ovarian function, including the production of gonadal steroid hormones. These hormones, in turn, provide important feedback signals to GnRH neurons via a hormone sensitive neuronal network in the brain. In many women with PCOS this feedback pathway is impaired, resulting in the downstream consequences of the syndrome. This review will explore what is currently known from clinical and animal studies about the identity, relative contribution and significance of the individual neuronal components within the GnRH neuronal network that contribute to the pathophysiology of PCOS. We review evidence for the specific neuronal pathways hypothesised to mediate progesterone negative feedback to GnRH neurons, and discuss the potential mechanisms by which androgens may evoke disruptions in these circuits at different developmental time points. Finally, this review discusses data providing compelling support for disordered progesterone-sensitive GABAergic input to GnRH neurons, originating specifically within the arcuate nucleus in prenatal androgen induced forms of PCOS.

Abstract
BACKGROUND AND AIMS Non-alcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) share risk associations of adiposity and insulin resistance. We examined the impact of a PCOS diagnosis on the metabolic phenotype of adolescent girls with NAFLD and compared this to girls without PCOS or NAFLD and to age-matched boys. METHODS Community-based adolescents from the Raine Cohort participated in assessments for NAFLD (572 girls and 592 boys) and PCOS (244 girls). One hundred and ninety-nine girls attended both assessments. RESULTS Amongst the 199 girls, PCOS was diagnosed in 16.1% and NAFLD in 18.6%. NAFLD was diagnosed in 10.1% of the boys. NAFLD was more prevalent in girls with PCOS than girls without PCOS (37.5% vs 15.1%, P = 0.003). Girls with NAFLD plus PCOS had greater adiposity (waist circumference, body mass index, suprailiac skinfold thickness [SST], serum androgens, high-sensitivity C-reactive protein, ferritin, homeostasis model assessment for insulin resistance (HOMA-IR), and lower serum sex hormone binding globulin levels than girls with NAFLD without a PCOS diagnosis (all P < 0.05). Girls with NAFLD plus PCOS had similar adiposity, HOMA-IR, and adiponectin levels to boys with NAFLD, but more adiposity, serum leptin and HOMA-IR than both girls and boys without NAFLD. PCOS (odds ratios 2.99, 95% confidence intervals 1.01-8.82, P = 0.048) and SST (odds ratios 1.14, 95% confidence intervals 1.08-1.20, P < 0.001) independently predicted NAFLD in adolescent girls, however, serum androgens and HOMA-IR levels did not. CONCLUSIONS Adolescent girls with NAFLD plus PCOS have a similar metabolic phenotype to boys with NAFLD. Increasing SST and pre-existing PCOS independently predict NAFLD in adolescent girls.

Abstract
Biochemical or clinical changes of hyperandrogenism are important elements of polycystic ovary syndrome (PCOS). There is currently no consensus on the definition and diagnostic criteria of hyperandrogenism in PCOS. The aim of this study was to investigate the complex symptoms of hyperandrogenic disorders and the correlations between metabolism and hyperandrogenism in patients with PCOS from an outpatient reproductive medicine clinic in China. We conducted a case control study of 125 PCOS patients and 130 controls to evaluate differences in body mass index (BMI), total testosterone (TT), modified Ferriman-Gallwey hirsutism score, sex hormone binding globulin (SHBG), homeostasis model assessment-estimated insulin resistance (HOMA-IR) and free androgen index (FAI) between PCOS patients and controls and subgroups of PCOS. The prevalence of acne and hirsutism did not differ significantly between the hyperandrogenic and non-hyperandrogenic subgroup. Patients with signs of hyperandrogenism had significantly higher BMI (P < 0.05), but differences in TT, SHBG, FAI and waist/hip ratio were insignificant. The odds ratio of overweight was calculated for all PCOS patients. Our results suggest that PCOS patients with high BMI tend to have functional disorders of androgen excess; therefore, BMI may be a strong predictor of hyperandrogenism in PCOS.

Abstract
BACKGROUND/OBJECTIVES Insulin resistance (IR) is a main pathophysiologic feature in polycystic ovary syndrome (PCOS) patients which is triggered by elevated oxidative stress in these patients. Selenium, an essential micronutrient, is a major constituent of antioxidant enzymes such as glutathione peroxidase. Recently, decreased plasma selenium concentrations were reported in PCOS patients. So, the present study was carried out in order to assess whether selenium consumption can improve the metabolic response to insulin and reduce the insulin resistance in these women. SUBJECTS/METHODS A total of 53 PCOS patients (diagnosed by Rotterdam criteria), 18-42 years old, participated in this randomized, double-blind and placebo controlled trial for 12 weeks (selenium, n=26; placebo, n=27). The effects of daily administration of 200 μg selenium or placebo on serum glucose, total testosterone (tT), sex hormone binding globulin (SHBG) and free androgen index (FAI) in fasting state were evaluated. RESULTS At the end of the study, insulin resistance was significantly increased in selenium recipients when compared with the placebo group (2.05 ± 0.39 when compared with 1.81 ± 0.25, p=0.017). Also, selenium supplementation resulted in marginally significant increase (p=0.056) in insulin level when compared with the placebo group. There were no statistically significant changes in other study endpoints, when comparing the two groups. CONCLUSION This study showed that selenium supplementation in PCOS patients may worsen insulin resistance in them. Until the results of larger studies become available, indiscriminate consumption of selenium supplements in PCOS patients will warrant caution.

Abstract
Background Metformin decreases polycystic ovary syndrome (PCOS) symptoms, induces ovulation, and may improve developmental competence of in vitro oocyte maturation. This study was designed to define the effects of metformin on the characteristics of in vitro oocyte maturation in estradiol valerate (EV) PCOS-induced rats. Methods Forty-five adult female Sprague–Dawley rats were randomly divided into control; sham and PCOS-induced (treated by a single dose of estradiol valerate, 4 mg/rat, IM) groups. The body weight was measured weekly for 12 weeks. At the end of week 12, the serum levels of testosterone, estrogen, progesterone, LH, and FSH and blood glucose of all the rats were measured. About 380 cumulus oocyte complexes (control, 125; sham, 122; PCOS-induced rats, 133) were incubated in Ham’s F10 in the absence and/or presence of metformin (M 5−10) for 12, 24, 36, and 48 h. The cumulus cells expansion and nuclear and cytoplasmic maturation of the oocytes was evaluated using 1 % aceto-orcein staining, and transmission electron microscopy (TEM). Results No significant differences were observed in the body weight of the rats. The serum level of testosterone was reduced, and progesterone and LH were significantly increased in the PCOS-induced rats (p < 0.05). However, no significant differences were observed in the serum levels of estrogen and FSH among the groups. Blood glucose level was higher in the PCOS-induced rats than control, (p < 0.01). The expansion of cumulus cells was observed in the metformin-treated oocytes. The oocytes retrieved from PCOS-induced rats show a stage of meiotic division (GVBD, MI, A-T, and MII) in 57.12 % of metformin-untreated and fairly significantly increased to 64.28 % in metformin-treated oocytes, (p < 0.05), but no differences were observed in the MII stage within groups. The redistribution of some cytoplasmic organelles throughout the ooplasm, particularly the peripheral cortical granules, was defined in the metformin-treated oocytes. Conclusions Single dose of EV can creates a reversible PCO adult rat model. Metformin enhances the COCs to initiate meiotic resumption at the first 6 h of IVM. In our study the metformin inability to show all aspects of in vitro oocyte maturation and may be resulted from deficiency of EV to induce PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is characterized by hormonal and metabolic abnormalities and is thought to increase a risk for cardiovascular diseases. In this study we use speckle tracking echocardiography (STE) to evaluate left ventricular (LV) dysfunction in the early period of the disease. We enrolled 31 patients with PCOS and 32 healthy volunteers as a control group. The participants' ages ranged between 18 and 40 years. PCOS was diagnosed according to the Rotterdam criteria. LV strain (LS) and strain rate (SR) were evaluated using apical two-chamber (2C), three-chamber (3C), and four-chamber (4C) imaging. Global LS and SR were calculated as average of three apical views. The waist-to-hip ratio, homeostasis model assessment-insulin resistance (HOMA-IR), and fasting insulin and triglyceride levels were higher in the PCOS group than in the controls (p=0.001, p=0.001, p=0.001, and p=0.005, respectively). In the PCOS group, the mitral A wave, deceleration time (DT), and isovolumetric relaxation time (IVRT) were significantly higher than in the controls (all p<0.05). The LV global longitudinal strain (GLS) and global longitudinal SR systolic (GLSRS) were significantly lower in the PCOS patient group (both p= 0.001). There were strong negative correlations between GLS and both fasting insulin (r=-0.64) and DT (r=-0.62) (both p<0.05). The study demonstrated that PCOS patients had decreased LV function using STE. Therefore, STE imaging appears to be useful for the early detection of subclinical LV dysfunction in patients with PCOS.

Abstract
OBJECTIVES To evaluate whether single nucleotide polymorphisms of HSD11B1 (rs846908) and H6PD (rs6688832 and rs17368528) are associated with polycystic ovary syndrome (PCOS) in Chinese population. MATERIALS AND METHODS A case-control study was implemented to investigate the association between HSD11B1 and H6PD polymorphisms and PCOS. Patients with PCOS (n = 335) and controls (n = 354) were recruited in this study. Genetic variants of HSD11B1 (rs846908) and H6PD (rs6688832 and rs17368528) were analyzed by TaqMan method. RESULTS We found a significantly 0.79-fold lower risk of G allele of rs6688832 in control group compared with the patients with PCOS (adjusted OR, 0.79; 95%CI = 0.63-0.99; P = 0.040). Additionally, significant difference in the levels of follicle stimulating hormone (FSH) was observed between AA and AG genotype in rs6688832. The rs6688832 AG genotype was associated with lower level of FSH (P = 0.039) and higher risk of hyperandrogenism (P = 0.016) in patients with PCOS. When all subjects were divided into different subgroups according to age and body mass index (BMI), we found that the frequency of G allele of rs6688832 was significantly higher in controls than that in PCOS patients in the subgroup of BMI > 23 (adjusted OR, 0.70; 95% CI = 0.50-0.98; P = 0.037). CONCLUSIONS Our findings showed a statistical association between H6PD rs6688832 and PCOS risk in Chinese population. The G allele of rs6688832 in H6PD might exert potential genetic protective role against the development of PCOS, especially in overweight women. PCOS patients with AG genotype of rs6688832 might confer risk to the phenotype of hyperandrogenemia of PCOS.

Abstract
OBJECTIVE To study the influence of polycystic ovary syndrome (PCOS) on obstetric and perinatal outcomes and on offspring in childhood. METHODS Using statewide data linkage systems within Western Australia, 2,566 hospitalized women with a PCOS diagnosis and at least one pregnancy at 20 weeks of gestation or greater, between 1997 and 2011, were compared with 25,660 randomly selected age-matched women not hospitalized with a PCOS diagnosis with regard to perinatal outcomes, congenital anomalies, and general health of offspring. Hospitalizations were categorized by International Classification of Diseases, 10th Revision diagnoses and rates by 10 years by Kaplan-Meier estimates. Polycystic ovary syndrome effects were summarized using adjusted odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) after controlling for maternal and perinatal characteristics, including maternal diabetes and obesity. RESULTS Of women with PCOS (n=1,789), 69.7% and 62.9% (n=16,139) of women without PCOS had one or more births. Hospitalizations up to 31 years were examined for 38,361 offspring. Offspring of women with PCOS were at higher risk of preterm birth (15.5% compared with 7.6% OR 1.74, 95% CI 1.53-1.98), perinatal mortality (2.3% compared with 0.7%, OR 1.49, 95% CI 1.02-2.18), more postnatal hospitalizations (14.1% compared with 7.9%, OR 1.21, 95% CI 1.05-1.40), more congenital anomalies (6.3% compared with 4.9%, OR 1.20, 95% CI 1.03-1.40), cardiovascular (1.5% compared with 1.0%, OR 1.37, 95% CI 1.01-1.87), and urogenital defects (2.0% compared with 1.4% OR 1.36, 95% CI 1.03-1.81). Maternal PCOS was associated with increased hospitalizations for their offspring, including metabolic disorder (7.9% compared with 5.3%, HR 1.43, 95% CI 1.26-1.65), disease of the nervous system (9.4% compared with 6.9%, HR 1.17, 95% CI 1.03-1.33), and asthma (6.9% compared with 4.9%, HR 1.32, 95% CI 1.13-1.54). CONCLUSION Controlling for increased perinatal risk, maternal PCOS was associated with a predisposition to adverse health outcomes for their offspring. LEVEL OF EVIDENCE II.

Abstract
Functional ovarian hyperandrogenism (FOH) is a form of polycystic ovary syndrome (PCOS) characterized by elevated circulating levels of androgens derived from the ovary. Insulin resistance (IR) is the most common etiological factor in women with FOH. IR causes the generation of increased oxidative stress (OS) and diminished antioxidant status. OS is directly correlated with both IR and testosterone levels, which consequently contribute to endocrine and biochemical alterations in FOH women. In the current study, elevations in total testosterone, free testosterone and luteinizing hormone (LH) levels accompanied by a decrease in follicle stimulating hormone (FSH) level leading to higher LH:FSH ratio were the prominent endocrine changes observed in women with FOH. A significant increase in fasting blood levels of glucose and insulin, as well as an elevated IR were also seen in FOH women, as compared to their age matched controls. Women with FOH have higher pro-oxidant and lower anti-oxidant levels in blood than their age matched controls. In FOH women, elevations in LH:FSH ratio and OS are correlated more with hyperandrogenemia than with IR. Of the androgens, free rather than total testosterone has better positive correlations with elevated LH:FSH ratio and OS, and hence, the former is a better predictive marker for the development of biochemical PCOS in women with FOH.

Abstract
Prenatal T excess induces maternal hyperinsulinemia, early puberty, and reproductive/metabolic defects in the female similar to those seen in women with polycystic ovary syndrome. This study addressed the organizational/activational role of androgens and insulin in programming pubertal advancement and periovulatory LH surge defects. Treatment groups included the following: 1) control; 2) prenatal T; 3) prenatal T plus prenatal androgen antagonist, flutamide; 4) prenatal T plus prenatal insulin sensitizer, rosiglitazone; 5) prenatal T and postnatal flutamide; 6) prenatal T and postnatal rosiglitazone; and 7) prenatal T and postnatal metformin. Prenatal treatments spanned 30-90 days of gestation and postnatal treatments began at approximately 8 weeks of age and continued throughout. Blood samples were taken twice weekly, beginning at approximately 12 weeks of age to time puberty. Two-hour samples after the synchronization with prostaglandin F2α were taken for 120 hours to characterize LH surge dynamics at 7 and 19 months of age. Prenatal T females entered puberty earlier than controls, and all interventions prevented this advancement. Prenatal T reduced the percentage of animals having LH surge, and females that presented LH surge exhibited delayed timing and dampened amplitude of the LH surge. Prenatal androgen antagonist, but not other interventions, restored LH surges without normalizing the timing of the surge. Normalization of pubertal timing with prenatal/postnatal androgen antagonist and insulin sensitizer interventions suggests that pubertal advancement is programmed by androgenic actions of T involving insulin as a mediary. Restoration of LH surges by cotreatment with androgen antagonist supports androgenic programming at the organizational level.

Abstract
OBJECTIVE To examine the role of adiponectin as a biomarker of insulin resistance in polycystic ovary syndrome (PCOS). BACKGROUND PCOS is associated with metabolic syndrome, which correlates to increased cardiovascular risk in these patients. Adiponectin is decreased in obese individuals. METHODS Ninety women with PCOS (45 with and 45 without metabolic syndrome) were enrolled in this study. Anthropometric variables, serum concentrations of fasting glucose, insulin, triglycerides, lipoproteins, cholesterol, testosterone and adiponectin were measured in all patients. Insulin sensitivity was examined in all patients. Numerical values were analyzed by t-tests and categorical data were analyzed by Chi-square test. Multiple regression analyses were performed to detect the factors that contributed to insulin resistance. RESULTS Metabolic syndrome predicted insulin resistance in PCOS patients. Serum adiponectin levels were suppressed in insulin resistant compared to insulin sensitive patients (10.7 ± 4.3 µg/mL, p < 0.001). Multiple linear regression analysis revealed for every 1 µg increase in adiponectin, insulin sensitivity index increases by 0.1 (p = 0.016). Serum testosterone failed to correlate with insulin sensitivity. CONCLUSION Serum adiponectin levels were suppressed in patients with both metabolic syndrome and insulin resistance. This protein could be used as a biomarker to distinguish the patients at a higher risk of diabetes and cardiovascular morbidity.

Abstract
Introduction Polycystic ovary syndrome is a common endocrine disorder affecting women both physically and psychologically and can lead to a poor quality of life compared to their normal counterparts. The aim of the present study was to assess the impact of various clinical features of polycystic ovary syndrome on the health-related quality of life of Iranian women diagnosed with this syndrome. Materials and Methods A total of 796 women diagnosed with polycystic ovary syndrome, aged 15–49 years, completed the questionnaires, interviews, and medical assessments required for this study. A reliable and validated Persian version of the health-related quality of life questionnaire for polycystic ovary syndrome patients was used. Linear regression models were used to assess the association between the symptoms of polycystic ovary syndrome and health-related quality of life. Results The mean age of participants was 28.02 years. 35.4% of the subjects were classified as overweight or obese. Hirsutism, was reported to have the strongest impact on the patients’ health-related quality of life, followed in descending order by body mass index, irregular menses and infertility. The relative level of hirsutism was directly proportional to decrease in health-related quality of life score (p<0.001). Conclusions The results of the study found that hirsutism had the strongest impact on the health-related quality of life measures in Iranian women diagnosed with polycystic ovary syndrome. Health care officials need to evaluate in depth the effect of each clinical feature of polycystic ovary syndrome separately and design management strategies, keeping in mind the psychological and physical manifestations.

Abstract
OBJECTIVE To compare ovarian stromal artery blood flows measured by Doppler ultrasonography of polycystic ovary syndrome (PCOS) patients and healthy women with polycystic ovarian image in ultrasonography. METHODS Forty-two patients diagnosed with PCOS according to the criteria of 2003 Rotterdam Concencus Conferance on PCOS and 38 healthy volunteers with polycystic ovarian image in ultrasonography were included in the study. Ovarian volumes and ovarian stromal artery blood flows were measured by 3-dimensional (3-D) ultrasonography and Doppler ultrasonography in all patients. RESULTS In patients with PCOS, ovarian stromal artery pulsatility index (PI) and resistivity index (RI) were found significantly different from healthy women with polycystic ovarian image in ultrasonography (p < 0.05). 3-D ovarian volumes were found significantly higher in patients with PCOS (p < 0.05), and a negative correlation was also obtained between ovarian volumes and ovarian stromal artery resistivity indices. CONCLUSION Ovarian stromal artery Doppler examination could have an importance to explain the pathophysiology of PCOS, but there are few publications in the literature about PCOS and the details of ovarian stromal artery Doppler parameters in patients with polycystic ovarian image only. We conclude that Doppler ultrasonography findings of PCOS patients might be helpful in understanding the clinical follow-up and etiology of the disease.

Abstract
Background This study aimed to investigate the effect of polycystic ovary syndrome (PCOS) on the association of aromatase activity assessed by estradiol-to-testosterone ratio (E2/T) with body mass index (BMI) in women. Methods This was a cohort study in five centers for reproductive medicine in China. Data were collected from July 2012 to December 2013. PCOS patients (n = 785) and non PCOS, healthy, age-matched controls (n = 297) were included. Plasma sex hormones including estradiol (E2), testosterone (T), follicle stimulating hormone (FSH), and luteinizing hormone (LH) were measured by ELISA, together with BMI and E2/T being calculated, on the third day of the menstrual cycle. Aromatase activity in PCOS patients with different BMI, T and E2 levels were compared. Results E2/T was significantly lower (P < 0.05) while BMI was significantly increased (P < 0.05) in PCOS than non-PCOS. No significant difference was observed in E2/T among different BMI subgroups of either PCOS or control. Ovarian aromatase activity was decreased in PCOS patients which was independent of BMI. Hyperestrogen promoted ovarian aromatase activity, while hyperandrogen inhibited such activity, both in a dose-dependent, biphasic manner. Conclusions Ovarian aromatase activity was lower in PCOS, which was independent of BMI. New therapeutic strategies can be developed by targeting aromatase activity for treating PCOS women, especially those with obesity.

Abstract
There is now considerable epidemiological and experimental evidence indicating that early-life environmental conditions, including nutrition, affect subsequent development in later life. These conditions induce highly integrated responses in endocrine-related homeostasis, resulting in persistent changes in the developmental trajectory producing an altered adult phenotype. Early-life events trigger processes that prepare the individual for particular circumstances that are anticipated in the postnatal environment. However, where the intrauterine and postnatal environments differ markedly, such modifications to the developmental trajectory may prove maladaptive in later life. Reproductive maturation and function are similarly influenced by early-life events. This should not be surprising, because the primordial follicle pool is established early in life and is thus vulnerable to early-life events. Results of clinical and experimental studies have indicated that early-life adversity is associated with a decline in ovarian follicular reserve, changes in ovulation rates, and altered age at onset of puberty. However, the underlying mechanisms regulating the relationship between the early-life developmental environment and postnatal reproductive development and function are unclear. This review examines the evidence linking early-life nutrition and effects on the female reproductive system, bringing together clinical observations in humans and experimental data from targeted animal models.

Abstract
The present meta-analysis aimed to investigate the association between insulin gene variable number of tandem repeats (INS VNTR) and polycystic ovary syndrome (PCOS). Systematic searches of electronic databases, reference lists of included articles, and the abstracts presented at related scientific societies meetings were performed. Statistical analyses were conducted using software Stata 11.0. The pooled odds ratios (ORs) with 95% confidence intervals (95% CIs) were applied. Publication bias was tested by Begg's funnel plot and Egger's regression test. A total of 9 studies including 1075 PCOS patients and 2878 controls were included in the meta-analysis. There were evidence of statistical significant association between INS VNTR and PCOS in allelic model (OR=1.25, 95% CI=1.08-1.43, P=0.002) and dominant model (OR=1.34, 95% CI=1.11-1.63, P=0.003) but not in additive model (OR=1.38, 95% CI=0.93-2.04, P=0.11) and recessive model (OR=1.26, 95% CI=0.96-1.65, P=0.09). No significant publication bias was shown by funnel plots and Egger's regression tests. In conclusion, our meta-analysis suggests that the III allele of INS VNTR is associated with increased risk of PCOS.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrinopathy, associated with metabolic abnormalities. Metabolic features of various phenotypes of this syndrome are still debatable. The aim of present study hence was to evaluate the metabolic and hormonal features of PCOS phenotypes in comparison to a group of healthy control. METHODS A total of 646 reproductive-aged women were randomly selected using the stratified, multistage probability cluster sampling method. The subjects were divided into five phenotypes: A (oligo/anovulation + hyperandrogenism + polycystic ovaries), B (oligo/anovulation + hyperandrogenism), C (hyperandrogenism + polycystic ovaries) and D (oligo/anovulation + polycystic ovaries). Hormonal and metabolic profiles and the prevalence of metabolic syndrome among these groups were compared using ANCOVA adjusted for age and body mass index. RESULTS Among women with PCOS (n = 85), those of groups A and C had higher serum levels of insulin and homeostatic model assessment for insulin resistance (HOMA-IR), compared to PCOS women of group D. Serum concentrations of cholesterol, low density lipoprotein, triglycerides and glucose in group A were higher than in other phenotypes, whereas the metabolic syndrome was more prevalent among group B. CONCLUSIONS Women who had all three components of the syndrome showed the highest level of metabolic disturbances indicating that metabolic screening of the severest phenotype of PCOS may be necessary.

Abstract
Prenatal testosterone (T) excess disrupts ovarian cyclicity and increases circulating estradiol levels as well as follicular recruitment and persistence culminating in multifollicular ovary similar to women with polycystic ovary syndrome. We tested whether prenatal T excess, by androgenic or estrogenic action, disrupts the steroid biosynthetic machinery in sheep in a cell-, follicle stage-, age-, and treatment-specific manner consistent with the ovarian disruptions and increased estradiol release. Impact of T/dihydrotestosterone (DHT) treatments from days 30-90 of gestation on steroidogenic acute regulatory protein, 3β-hydroxysteroid dehydrogenase, cytochrome P-450 17α-hydroxylase/C17, 20-lyase (CYP17A1), and cytochrome P-450 aromatase (CYP19A1) were examined on fetal day 90, 140 and 10 months (postpubertal), and 21 months (adult, no DHT group) of age by immunohistochemistry. All 4 markers changed in a cell-, follicle stage-, and age-specific manner. Both treatments increased steroidogenic acute regulatory protein expression in preantral follicles of postpubertal and adult females. Effects of prenatal T and DHT on 3β-hydroxysteroid dehydrogenase differed in a follicle- and age-specific manner. CYP17A1 was reduced in the theca interna of antral follicles by T, but not DHT, in 10- and 21-month-old females. CYP19A1 was reduced by both T and DHT at all ages barring an increase on fetal day 140. Reduced granulosa CYP19A1 and thecal CYP17A1 in adults likely disrupt the intrafollicular androgen/estrogen balance contributing to follicular persistence. The reduced thecal CYP17A1 expression suggests that the hyperandrogenic ovarian phenotype may originate from increased enzyme activity or alternatively via a different isoform of CYP17. The reduced CYP19A1 in antral follicles of adults indicates that the increased circulating estradiol release likely arises from the increased number of persisting follicles.
