An in-depth analysis of perinatal related mortality among women of South Asian ethnicity in Aotearoa New Zealand. BMC Pregnancy Childbirth 2023; 23:535. [PMID: 37488505 PMCID: PMC10364368 DOI: 10.1186/s12884-023-05840-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 07/10/2023] [Indexed: 07/26/2023] Open
Abstract
BACKGROUND International and national New Zealand (NZ) research has identified women of South Asian ethnicity at increased risk of perinatal mortality, in particular stillbirth, with calls for increased perinatal research among this ethnic group. We aimed to analyse differences in pregnancy outcomes and associated risk factors between South Asian, Māori, Pacific and NZ European women in Aotearoa NZ, with a focus on women of South Asian ethnicity, to ultimately understand the distinctive pathways leading to adverse events. METHODS Clinical data from perinatal deaths between 2008 and 2017 were provided by the NZ Perinatal and Maternal Mortality Review Committee, while national maternity and neonatal data, and singleton birth records from the same decade, were linked using the Statistics NZ Integrated Data Infrastructure for all births. Pregnancy outcomes and risk factors for stillbirth and neonatal death were compared between ethnicities with adjustment for pre-specified risk factors. RESULTS Women of South Asian ethnicity were at increased risk of stillbirth (aOR 1.51, 95%CI 1.29-1.77), and neonatal death (aOR 1.51, 95%CI 1.17-1.92), compared with NZ European. The highest perinatal related mortality rates among South Asian women were between 20-23 weeks gestation (between 0.8 and 1.3/1,000 ongoing pregnancies; p < 0.01 compared with NZ European) and at term, although differences by ethnicity at term were not apparent until ≥ 41 weeks (p < 0.01). No major differences in commonly described risk factors for stillbirth and neonatal death were observed between ethnicities. Among perinatal deaths, South Asian women were overrepresented in a range of metabolic-related disorders, such as gestational diabetes, pre-existing thyroid disease, or maternal red blood cell disorders (all p < 0.05 compared with NZ European). CONCLUSIONS Consistent with previous reports, women of South Asian ethnicity in Aotearoa NZ were at increased risk of stillbirth and neonatal death compared with NZ European women, although only at extremely preterm (< 24 weeks) and post-term (≥ 41 weeks) gestations. While there were no major differences in established risk factors for stillbirth and neonatal death by ethnicity, metabolic-related factors were more common among South Asian women, which may contribute to adverse pregnancy outcomes in this ethnic group.

Abstract
INTRODUCTION Women of South Asian ethnicity are overrepresented in adverse pregnancy outcomes across high-income countries, including placental dysfunction and antepartum haemorrhage. As the burden of mortality is highest for extremely preterm infants, we aimed to identify any differences in placental pathology among perinatal deaths from 20+0 to 27+6 weeks gestation between South Asian, Māori and New Zealand (NZ) European women in Aotearoa NZ, with a focus on women of South Asian ethnicity. METHODS Placental pathology reports and clinical data from perinatal deaths between 2008 and 2017 were provided by the NZ Perinatal and Maternal Mortality Review Committee, blinded and analysed by an experienced perinatal pathologist using the Amsterdam Placental Workshop Group Consensus Statement criteria. South Asian ethnicity was classified as Indian, Fijian Indian, South African Indian, Sri Lankan, Pakistani and Bangladeshi. RESULTS 886 of 1571 placental pathology reports met the inclusion criteria. Women of South Asian ethnicity were significantly more likely to show features of histologic chorioamnionitis (aOR 1.87, 95%CI 1.19-2.94) and chorionic vasculitis (aOR 1.92, 95%CI 1.13-3.29), than NZ European and Māori women respectively. 13 of 15 (87%) of South Asian mothers with a diabetic disorder were identified with chorioamnionitis, compared to 1 in 5 (20%) of Māori and 5 in 12 (41%) of NZ European women. Cord hyper-coiling was also more common among South Asian pregnancies, compared to NZ European (aOR 1.98, 95%CI 1.10-3.56). DISCUSSION Differences in placental pathology by ethnicity were observed among extremely preterm perinatal deaths. Underlying metabolic disorders and an associated pro-inflammatory environment may play an important role in the causal pathway leading to these deaths in women of South Asian ethnicity.

Abstract
BACKGROUND Prevalence of adult patients with acne is increasing and women comprise majority of the cases. There is lack of data on biochemical and hormonal abnormalities in adult female acne (AFA). AIMS To evaluate biochemical and hormonal parameters in 60 patients of AFA. METHODS A cross-sectional observational study conducted from November 2018 to March 2020 in Dermatology outpatient department of a tertiary care hospital in North India. Adult females (age > 25 years) with a clinical diagnosis of acne were included in the study. RESULTS 60 cases of AFA were included. The age ranged between 26-41 years with mean age at presentation being 29.45 years. 53.3% patients had persistent acne while 46.7% had late-onset acne. 50% patients had history of premenstrual flare-up of their acne. Raised FBG was found in 25% patients. 10% had raised serum insulin levels. HOMA-IR index was deranged in 55% patients. At least one lipid alteration was reported in 91.6% of patients. In hormonal parameters, raised TT was present in 6.7%, LH in 3.3%, FSH in 18.3%, prolactin in 3.3%, and TSH in 15%. No association was found between acne severity and biochemical and hormonal parameters. CONCLUSIONS Our study highlighted the importance of measuring lipid profile in AFA and calculating HOMA-IR index for measuring insulin resistance rather than simply measuring serum insulin levels. In our study, additional parameter deranged in significant number of patients was FBG. Hence, we recommend routine screening of lipid profile, FBG and calculation of HOMA-IR index in AFA.

Abstract
Background: One of the most common endocrine disorders in women during reproductive age is polycystic ovary
syndrome (PCOS). This study aimed to evaluate sexual functioning among women with PCOS in a sample of a region’s
population in the west of Iran. Materials and Methods: This study was a cross-sectional study that was conducted on 130 women with PCOS who
referred to three clinics of gynecology, infertility, and dermatology affiliated with Hamadan University of Medical
Sciences, Iran, from September to November 2020. The measurement tools included demographic characteristics,
hirsutism score, and sexual function was assessed using the female sexual function index (FSFI) questionnaire. Results: In total, 60% of patients had reported sexual dysfunction related to lubrication, satisfaction, and pain as domains
of sexual dysfunction. The number 109 (83.85%) of them had hirsutism and these patients had a lower score for
lubrication (3.7 ± 1.47 vs. 4.47 ± 1.71, P=0.03), orgasm (3.2 ± 1.34 vs. 3.95 ± 1.37, P=0.02), satisfaction (3.4 ± 1.29
vs. 3.71 ± 1.33, P=0.03), and FSFI score (22.56 ± 5.78 vs. 25.42 ± 5.51, P=0.04). Women with higher education had
reported higher scores of FSFI and its domains. Rural participants had a higher arousal score (3.93 ± 1.4 vs. 3.37 ±
1.28, P=0.04). Moreover, housekeeper women had higher scores regarding desire, pain, and total FSFI score. Conclusion: Our results showed that there was a significant association between hirsutism and FSFI scores, different
domains, including lubrication, orgasm, and satisfaction.

Abstract
The aim of this cross-sectional study, that included 146 polycystic ovary syndrome (PCOS) patients, was to evaluate the prevalence, severity and pattern of cutaneous manifestation in Jordanian women with PCOS, as well as their correlation with hormonal abnormalities. A thorough complete cutaneous examination, hormonal assays (Luteinizing hormone [LH], follicle stimulating hormone [FSH], prolactin, total testosterone, free testosterone, dehydroepiandrosterone sulfate) and pelvic ultrasonography were done. The most common cutaneous features of PCOS were acne vulgaris (75.3%) followed by hirsutism (59.6%) then seborrhea (43.2%) and androgenetic alopecia (42.5%). Patients who had acne vulgaris presented at a younger age than patients who did not. Patients who had androgenetic alopecia and stria were older than patients with no such features. Moreover, all cutaneous manifestations of PCOS, except for acne, were associated with higher body mass index (BMI). Elevated LH:FSH ratio of more than 2:1 was the most common hormonal abnormality, followed by increased LH and total testosterone. Acne, hirsutism, androgenetic alopecia, seborrhea, acanthosis nigricans and skin tags are common cutaneous manifestations among Jordanian patients with PCOS. The existence of one or more of these features, especially in overweight and obese patients, should alert the physician towards the possibility of having PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among reproductive-aged women; however, to date there has been no synthesis of the burden of PCOS specifically among indigenous women. We aimed to systematically identify and collate studies reporting prevalence and clinical features of PCOS among indigenous women worldwide. We performed a comprehensive search of six databases (Ovid MEDLINE, MEDLINE In Process & Other Non-Indexed Citations, EMBASE, EBM reviews, CINAHL, and SCOPUS) supplemented by gray literature searches and the screening of reference lists. A narrative synthesis was conducted. Fourteen studies met inclusion criteria; however, one was excluded as it assessed only children and adolescents younger than 15 years, with limited clinical relevance. Studies examined indigenous women from Australia, Sri Lanka, New Zealand, and the United States. Prevalence of PCOS was reported in only four studies and ranged from 3.05% for women in Sri Lanka to 26% for women in Australia. All included studies reported on at least one clinical feature of PCOS. Of the studies that reported on a comparison group from the same country, there was evidence of more severe features in indigenous women from New Zealand and the United States. The limited evidence available warrants further investigation of the burden of PCOS in indigenous women to build the knowledge base for effective and culturally relevant management of this condition.

Abstract
The literature suggests that ethnicity affects live birth rate (LBR) and preterm birth (PTB) rate after fresh but not frozen embryo transfer (FET). We analysed 64,530 FET cycles from 2000 to 2016 using the Human Fertilisation and Embryology Authority (HFEA) database. Ethnicity was recorded for 43,735 as White British, 3,034 as Indian, 1,946 as Pakistani, 1,400 as Black African, 1,090 as White Irish, 520 as Chinese, 319 as Bangladeshi and 277 as Black Caribbean women. The LBR per FET when compared with White British women (26.1%) was significantly reduced in women of White Irish (23.4%; adjusted Odds Ratio (aOR) 0.85, 95% CI 0.73 to 1.00), Indian (25.2%; aOR 0.95, 95% CI 0.91 to 0.99), Bangladeshi (21.1%; aOR 0.87, 95% CI 0.79 to 0.95) and Pakistani (25.7%; aOR 0.97, 95% CI 0.94 to 0.99) ethnicities. The PTB rate, when compared with White British women (8.4%) was significantly higher for women of Indian (11.1%; aOR 1.38, 95% CI 1.06 to 1.79), Pakistani (11.8%; aOR 1.49, 95% CI 1.09 to 2.03) and White Irish (12.3%; aOR 1.55, 95% CI 1.01 to 2.38) ethnicities. This study suggests that FET outcomes are influenced by ethnicity.

Abstract
This systematic review aimed to assess variations in the clinical presentation and treatment outcomes of patients with polycystic ovary syndrome (PCOS) belonging to different ethnicities. A search was performed for studies comparing various clinical aspects of PCOS in two or more different ethnic groups. After screening 2264 studies, 35 articles were included in the final analysis. In comparison with White women with PCOS (wPCOS), East Asian women with PCOS (eaPCOS) were less hirsute, whereas Hispanic women with PCOS (hPCOS), South Asian women with PCOS (saPCOS) and Middle Eastern women with PCOS (mePCOS) were more hirsute. saPCOS had higher androgen and lower sex hormone-binding globulin (SHBG) concentrations, mePCOS had higher DHEAS concentrations, and hPCOS and Black women with PCOS (bPCOS) had lower SHBG and DHEAS measures than wPCOS. Menstrual disturbances were more frequent in eaPCOS. Both saPCOS and eaPCOS had lower body mass index with increased central adiposity. hPCOS and bPCOS were more obese. saPCOS, mePCOS, hPCOS and bPCOS had a higher prevalence of insulin resistance than wPCOS. bPCOS had a better lipid profile but higher blood pressure and cardiovascular risk. Indigenous Australian women with PCOS were more obese and more insulin resistant with higher androgen concentrations. The clinical phenotype of PCOS therefore shows a wide variation depending on ethnicity.

Abstract
OBJECTIVE The aim of this study was to develop a simple phenotypic algorithm that can capture the underlying clinical and hormonal abnormalities to help in the diagnosis and risk stratification of polycystic ovary syndrome (PCOS). METHODS The study consisted of 111 women with PCOS fulfilling the Rotterdam diagnostic criteria and 67 women without PCOS. A Firth's penalized logistic regression model was used for independent variable section. Model optimism, discrimination and calibration were assessed using bootstrapping, area under the curve (AUC) and Hosmer-Lemeshow statistics, respectively. The prognostic index (PI) and risk score for developing PCOS were calculated using independent variables from the regression model. RESULTS Firth penalized logistic regression model with backward selection identified four independent predictors of PCOS namely free androgen index [β 0.30 (0.12), P = 0.008], 17-OHP [β = 0.20 (0.01), P = 0.026], anti-mullerian hormone [AMH; β = 0.04 (0.01) P < 0.0001] and waist circumference [β = 0.08 (0.02), P < 0.0001]. The model estimates indicated high internal validity (minimal optimism on 1000-fold bootstrapping), good discrimination ability (bias corrected c-statistic = 0.90) and good calibration (Hosmer-Lemeshow χ2 = 3.7865). PCOS women with a high-risk score (q1 + q2 + q3 vs q4) presented with a worse metabolic profile characterized by a higher 2-hour glucose (P = 0.01), insulin (P = 0.0003), triglycerides (P = 0.0005), C-reactive protein (P < 0.0001) and low HDL-cholesterol (P = 0.02) as compared to those with lower risk score for PCOS. CONCLUSIONS We propose a simple four-variable model, which captures the underlying clinical and hormonal abnormalities in PCOS and can be used for diagnosis and metabolic risk stratification in women with PCOS.

Abstract
BACKGROUND Cutaneous features of hyperandrogenism in polycystic ovary syndrome (PCOS) include acne, hirsutism, seborrhea, androgenic alopecia (AGA), and acanthosis nigricans (AN). However, the relationships have not been well known broadly in terms of clinical hyperandrogenism and biochemical markers. OBJECTIVES The aim of this study was to investigate biochemical and metabolic parameters in relation to cutaneous characters women in with and without PCOS. METHODS This was a cross-sectional retrospective study including 186 women with PCOS and 113 age-matched without PCOS women. Acne grade, hirsutism, seborrhea, AGA, and AN were recorded. Hormonal and metabolic parameters were measured. RESULTS The most common finding was acne, and AN was the least dermatological manifestations between PCOS and non-PCOS groups. The severity location and type of acne did not differ in PCOS women compared to non-PCOS women. Significant differences were found with respect to free androgen index (FAI) (P = .036), sex hormone-binding globulin (SHBG) (P = .023), and body mass index (BMI) (P = .001) between PCOS with acne and PCOS without acne groups. Overall, age (P = .005) was significantly decreased, while BMI (P = .004) was significantly higher in PCOS with hirsutism. The mean serum total testosterone (TT), dehydroepiandrosterone sulfate, and FAI were significantly elevated, but SHBG was decreased between PCOS with and without hirsutism groups. There were significantly different BMI (P = .018) and triglyceride (P = .024) except other hormonal parameter of without AGA group. CONCLUSION This study indicated a strong correlation between hirsutism and metabolic abnormalities. Hirsutism is the most common cutaneous finding in PCOS women. Acne and AGA are associated with other manifestations of clinical hyperandrogenism, but not obvious markers of biochemical hyperandrogenemia and metabolic dysfunction.

Abstract
Polycystic ovary syndrome (PCOS) was hypothesized to result from functional ovarian hyperandrogenism (FOH) due to dysregulation of androgen secretion in 1989-1995. Subsequent studies have supported and amplified this hypothesis. When defined as otherwise unexplained hyperandrogenic oligoanovulation, two-thirds of PCOS cases have functionally typical FOH, characterized by 17-hydroxyprogesterone hyperresponsiveness to gonadotropin stimulation. Two-thirds of the remaining PCOS have FOH detectable by testosterone elevation after suppression of adrenal androgen production. About 3% of PCOS have a related isolated functional adrenal hyperandrogenism. The remaining PCOS cases are mild and lack evidence of steroid secretory abnormalities; most of these are obese, which we postulate to account for their atypical PCOS. Approximately half of normal women with polycystic ovarian morphology (PCOM) have subclinical FOH-related steroidogenic defects. Theca cells from polycystic ovaries of classic PCOS patients in long-term culture have an intrinsic steroidogenic dysregulation that can account for the steroidogenic abnormalities typical of FOH. These cells overexpress most steroidogenic enzymes, particularly cytochrome P450c17. Overexpression of a protein identified by genome-wide association screening, differentially expressed in normal and neoplastic development 1A.V2, in normal theca cells has reproduced this PCOS phenotype in vitro. A metabolic syndrome of obesity-related and/or intrinsic insulin resistance occurs in about half of PCOS patients, and the compensatory hyperinsulinism has tissue-selective effects, which include aggravation of hyperandrogenism. PCOS seems to arise as a complex trait that results from the interaction of diverse genetic and environmental factors. Heritable factors include PCOM, hyperandrogenemia, insulin resistance, and insulin secretory defects. Environmental factors include prenatal androgen exposure and poor fetal growth, whereas acquired obesity is a major postnatal factor. The variety of pathways involved and lack of a common thread attests to the multifactorial nature and heterogeneity of the syndrome. Further research into the fundamental basis of the disorder will be necessary to optimally correct androgen levels, ovulation, and metabolic homeostasis.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is one of the most common endocrinological disorders among women of reproductive age and the leading cause of female infertility. This study intends to evaluate the lipid profile, hormonal levels [free T3 (fT3), free T4 (fT4), thyroid stimulating hormone (TSH), insulin, luteinizing hormone (LH), follicle stimulating hormone (FSH), and prolactin] in PCOS women from Nellore and its surrounding districts of Andhra Pradesh, India. MATERIALS AND METHODS This cross-sectional study included 80 newly diagnosed PCOS women and an equal number of age and body mass index (BMI) matched healthy controls. We used the photometry methods to determine serum glucose levels and the lipid profile. An immunoturbidometry method was employed to measure high sensitive C-reactive protein (hsCRP). All hormonal parameters were measured using chemiluminescence immunoassays. Insulin resistance was evaluated using the homeostatic model assessment-insulin resistance (HOMA-IR) method. Statistical analysis was done using SPSS software version 20.0. RESULTS The PCOS patients presented statistically higher levels of total cholesterol (TC), triglycerides (TG) and low density lipoprotein cholesterol (LDL-c, P<0.0001) when compared to those of controls. PCOS patients had elevated fasting glucose, hsCRP, fasting insulin, TSH, LH and prolactin levels (P<0.001). An increased LH/FSH ratio (>1.5) was seen in women with PCOS compared with control women. In addition, we observed a direct correlation between fasting insulin with fasting glucose and HOMA-IR. LH was inversely proportional to BMI. CONCLUSION The present study showed a higher prevalence of insulin resistance, dyslipidemia, and hypothyroidism in PCOS women. Furthermore this study showed increased LH concentrations, a higher LH/FSH ratio, and higher prolactin levels in PCOS women.

Abstract
PURPOSE Hirsutism is the most common indicator of hyperandrogenism. Both, the sensitivity of the patients to the serum androgen levels and the responsiveness of women to the perceived excess hair growth vary among different populations. This report elaborates the relationship between the woman's discerned abnormal hair growths with the clinical diagnosis of hirsutism. METHODS The survey was conducted among 1160 women aged 18-45 and randomly selected from Tehran Lipid and Glucose Study for further detailed assessment of Hirsutism; using the m-FG scoring method. Data gathering was performed by interviews and physical examinations. The receiver operating characteristic curve was drawn and the new cutoff value, sensitivity, specificity and concordance percentage were calculated. RESULTS The results demonstrated that among 12 androgen-dependent body areas, the chin skin had the highest area under curve of 0.81 (CI; 0.78-0.84). According to the patient's evaluation, a threshold point of 4 had the optimum concordance percentage of 0.77 with the modified Ferriman-Gallwey scoring system. CONCLUSIONS Patient's self-identification of excess terminal hair based on the chin area has great sensitivity and reliability in predicting the clinical hirsutism.

Abstract
Hirsutism, acne, and androgenetic alopecia are classically considered signs of cutaneous hyperandrogenism (CHA). These common skin findings have significant impacts on the quality of patients' lives and pose the diagnostic challenge of excluding underlying disorders. Many with CHA have normal serum androgen levels. Hirsutism is more strongly associated with hyperandrogenism than are acne or androgenetic alopecia. Variable association of CHA with hyperandrogenemia results from the complexity of the underlying pathophysiology, including factors local to the pilosebaceous unit. CHA often occurs in the setting of polycystic ovary syndrome, the most common disorder of hyperandrogenism, but can also present in uncommon conditions, including nonclassic adrenal hyperplasia and androgen-producing tumors. A thorough history and full skin examination are important to guide appropriate diagnostic evaluation. Oral contraceptive pills with or without antiandrogens can provide therapeutic benefit for hirsutism and acne. Medical options for androgenetic alopecia remain limited. Multidisciplinary approaches may be needed given endocrine, metabolic, reproductive, and psychiatric disorders associated with CHA. More high-quality studies into the mechanisms of CHA and the benefits of antiandrogenic therapies are needed. We provide an evidence-based review of key diagnostic and therapeutic considerations in the treatment of women with CHA.

Abstract
Introduction Polycystic ovary syndrome (PCOS) is one of the most common endocrine-metabolic disorders. Evidence of familial aggregation analysis and different clinical traits among different regions and ethnicities indicated that the pathogenesis of PCOS is associated with multiple genetic and environmental factors. Our previous research had identified three susceptibility loci (rs2479106, DENND1A; rs13405728, LHCGR; rs13429458, THADA) for PCOS in Han Chinese women. The overall aim of this study was to investigate the relationship between three susceptibility gene polymorphisms and PCOS in Hui ethnic women. Methods 151 patients with PCOS (case group) and 99 healthy women (control group) were recruited from the Reproductive Medicine Center of the General Hospital of Ningxia Medical University. Clinical data and serum hormone characteristics of case and control groups were collected and analyzed. The three susceptibility single-nucleotide polymorphisms have been replicated in both case and control groups. Gene polymorphisms were detected by direct sequencing after polymerase chain reaction. Results The Body Mass Index, LH, LH/FSH ratio and total testosterone were significantly elevated in PCOS patients compared to control group (P<0.05). The frequencies of genotype and allele in rs13405728 were significantly different between the PCOS and the control groups (P<0.05). Of the SNP rs13405728, the PCOS cases with TT genotype stayed at a higher level of total testosterone, TG and LDL than those with the CC and CT genotypes. In contrary, there was no statistical difference between the two groups for SNP rs13429458 and rs2479106 (P>0.05). Conclusion The present study suggested that the SNP rs13405728 in the LHCGR gene was associated with PCOS in Hui ethnic women, and its TT genotype characterized with higher level of TT, TG and LDL.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common disorder. PCOS women are at a high risk for insulin resistance and metabolic syndrome (MS). Adiponectin is positively related to insulin sensitivity. It has a preventive role in atherogenesis and MS. The present work was conducted to study the correlation between serum adiponectin levels and clinical characteristics and biochemical parameters in PCOS patients. MATERIALS AND METHODS A prospective study in 49 newly diagnosed (as per Rotterdam criteria) Indian PCOS women was conducted. PCOS women were clinically examined and investigated for biochemical parameters. RESULTS The mean serum adiponectin was 12 ± 9.4 μg/mL (range 0.47-45). Hypoadiponectinemia (serum adiponectin <4 μg/mL) was present in 22% patients. Age and adiponectin correlated significantly and inversely (r = -0.42, P = 0.027). Overweight/obese patients had lower mean adiponectin levels than normal weight (11.62 ± 9.5 vs 13.58 ± 9.5, P = 0.56). It was significantly lower in patients with acanthosis nigricans (AN) as compared with those without AN (8.4 ± 5.9 vs 15 ± 11, P = 0.038). Hirsute patients showed lower mean adiponectin levels than nonhirsute (10 ± 7.3 vs 13 ± 10, P = 0.57). A positive, insignificant correlation was observed between serum adiponectin and cholesterol, low-density lipoprotein, follicle stimulating hormone (FSH), thyroid stimulating hormone, levels. A negative insignificant correlation existed between serum adiponectin and luteinizing hormone (LH), LH: FSH ratio, prolactin, dehydroepiandrosterone, testosterone, triglyceride, high-density lipoprotein, fasting blood glucose, fasting insulin, and Homeostasis Model Assessment. CONCLUSION Hypoadiponectinemia is present in one-fifth of women with PCOS. Adiponectin levels decrease as age advances. Low levels of adiponectin possibly contributes to the development of dermal manifestation (AN) of insulin resistance.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine problem affecting women of reproductive age and is investigated from many regions of the world. Some reports have indicated ethnic difference in its manifestation. This review addressed the evidences for ethnic variation in the expression of PCOS phenotypes and explored the potential ethnic-specific diagnosis of this syndrome. To determine ethnic variation, community prevalence and clinical and metabolic problems, including hyperandrogenism, oligomenorrhoea/amenorrhoea, polycystic ovaries, obesity, insulin resistance and the metabolic syndrome, had been compared from differing backgrounds and populations. Moreover, a link between ethnicity and variation in the metabolic phenotype of PCOS had also been identified. East Asian women with PCOS have a lower BMI and a milder hyperandrogenic phenotype, but with the highest prevalence of metabolic syndrome. South Asians in particular have a high prevalence of insulin resistance and metabolic syndrome, and are at risk for type 2 diabetes, with central obesity more than BMI reflecting their metabolic risk. African American and Hispanic women are more obese and more prone to metabolic problems. Besides, there is a higher prevalence of hirsutism among women of Middle Eastern and Mediterranean origin. Ethnically appropriate guidelines are needed for identifying anthropometric thresholds for better screening and diagnosis in high-risk ethnic groups.

Abstract
OBJECTIVE To determine whether manifestations of polycystic ovary syndrome (PCOS), particularly androgen excess, differ between Caucasian and Asian women in the San Francisco Bay Area. DESIGN Cross-sectional study. SETTING Multidisciplinary PCOS clinic at a tertiary academic center. PATIENT(S) 121 Caucasian and 28 Asian women, aged 18-44, examined between 2006 and 2011 with PCOS verified by a reproductive endocrinologist and dermatologist according to the Rotterdam criteria. INTERVENTION(S) Transvaginal ultrasounds, comprehensive dermatologic exams, and serum testing. MAIN OUTCOME MEASURE(S) Hirsutism defined as a modified Ferriman-Gallwey (mFG) score ≥ 8, acne, androgenic alopecia, and biochemical hyperandrogenism. RESULT(S) Caucasian and Asian women had a similar prevalence of all measures of androgen excess. Both groups had similar total mFG scores and site-specific mFG scores, except Asian women had a lower site-specific mFG score for the chest. Although Asian women were more likely to use laser hair removal, the results were unchanged when the women with a history of laser hair removal were excluded. CONCLUSION(S) Caucasian and Asian women with PCOS living in the same geographic region had a similar prevalence of hirsutism as well as other markers for androgen excess. Further studies are necessary to evaluate the need for ethnic-specific mFG scores in women with PCOS.

Abstract
Being the most common endocrinopathy of young women, polycystic ovary syndrome has much variation in its clinical expression based on ancestry. Ethnic differences of the phenotype are closely linked to its complex pathophysiology. This paper reviews data of the past three decades ensuring a precise diagnosis and taking into account underlying factors, effects of migration including heterogeneity, and diversity within each identified ethnic group. Differing expressions of hyperandrogenism, obesity, insulin resistance and metabolic manifestations of polycystic ovary syndrome occur among women from distinct geographic locations and ancestry. These ethnic phenotypes correlate with their inherent metabolic risks, skin sensitivity to androgens and social outlook that particularly affects their quality of life and health-seeking behavior. It is recommended that such ethnic variations are recognized in routine clinical practice and longitudinal data be maintained to study the true impact of such differences on disease outcomes.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is common diagnosis in women presenting with infertility. All the dimensions of PCOS have not been completely explored. Many studies have tried to characterize the exact presentation of the disease. In this study we studied clinical features of PCOS in Indian women to characterize different phenotypes of this syndrome. Prevalence of acanthosis nigricans (AN) as surrogate marker of insulin resistance, obesity, hirsutism and hypothyroidism in PCOS women have been simultaneously studied. MATERIALS AND METHODS Present work is a non comparative cross-sectional open label study carried out over a period of 18 months in an endocrinology hospital in western Maharashtra, India. RESULTS AND CONCLUSION Authors conclude that PCOS occurs both in obese and non-obese women; AN and hirsutism occur in equal proportion of patients. AN is correlated with obesity. Hormonal dysfunctions in PCOS manifested together or independently. PCOS women can be sub grouped based on clinical features suggestive of endocrinological malfunctions and can be investigated accordingly for selection of appropriate treatment modalities.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females, with a high prevalence. The etiology of this heterogeneous condition remains obscure, and its phenotype expression varies. Two widely cited previous ESHRE/ASRM sponsored PCOS consensus workshops focused on diagnosis (published in 2004) and infertility management (published in 2008), respectively. The present third PCOS consensus report summarizes current knowledge and identifies knowledge gaps regarding various women's health aspects of PCOS. Relevant topics addressed-all dealt with in a systematic fashion-include adolescence, hirsutism and acne, contraception, menstrual cycle abnormalities, quality of life, ethnicity, pregnancy complications, long-term metabolic and cardiovascular health, and finally cancer risk. Additional, comprehensive background information is provided separately in an extended online publication.

Abstract
BACKGROUND American Samoa and Samoa are now characterized by one of the world's highest levels of adult overweight and obesity. Our objective was to investigate patterns of menstrual cyclicity reported by Samoan women and examine the relationship to adiposity and select hormone levels. METHODS A cross-sectional analysis was performed among Samoan women, aged 18-39 years (n = 322), using anthropometric and biomarker measures of adiposity and reproductive health, including insulin, adiponectin, testosterone, sex hormone-binding globulin, free androgen index (FAI) and mullerian-inhibiting substance (MIS). Menstrual regularity was assessed from self-reported responses. Multivariable models were estimated to adjust for potential confounding of the associations between menstrual patterns and other measures. RESULTS A high proportion of the women (13.7%) reported oligomenorrhea or amenorrhea (OM/AM). More than three-quarters, 80.7%, of women were either overweight or obese, using Polynesian-specific criteria, and OM/AM was significantly associated with higher BMI. Abdominal circumference and insulin levels were significantly higher, and adiponectin levels were lower, in those who reported OM/AM versus regular menstruation. The FAI was higher in women with increased BMI. MIS levels declined with age, more slowly in those reporting OM/AM. CONCLUSIONS Self-reported OM/AM was associated with an elevated BMI, abdominal adiposity and serum insulin, and with reduced adiponectin levels. These findings support a high rate of metabolic syndrome, and perhaps PCOS and reproductive dysfunction, among Samoan women.

Abstract
BACKGROUND The objectives of this study were to define the distribution of the modified Ferriman-Gallwey (mF-G) score in a random group of Korean women and to study any association(s) between hirsutism and endocrine/metabolic markers. METHODS A single investigator assessed the mF-G score prospectively in 1010 Korean women, who consulted a health-care center as part of a group check-up for employment. Logistic regression models were utilized to test the relationships between the presence of hirsutism and levels of endocrine/metabolic markers. RESULTS Subjects had mF-G scores ranging from 0 to 19, and 505 subjects (50.0%) had an mF-G score of zero. Of the 1010 subjects, 95.1% had a score at or below six; thus, a score of six or greater represented hirsute women in our population. The most frequently affected site was the upper back, but the most densely affected area was found to be the lower abdomen. Hirsutism was significantly and positively associated with serum levels of total testosterone (T) and hemoglobin A1(c), but negatively associated with those of sex hormone binding globulin (SHBG). In addition, the odds of a woman developing hirsutism were higher for increased total T and HbA1(c), and lower for decreased SHBG. Hirsutism and homeostatic model assessment for insulin resistance were positively associated, but the relationship was not significant after adjusting for age and BMI. CONCLUSIONS mF-G scores greater that six represent the appropriate diagnostic cutoff for the detection of hirsutism in Korean women. Increased serum total T and HbA1(c,) and decreased SHBG concentrations were associated with the presence of hirsutism.

Abstract
BACKGROUND AND AIMS Obesity plays pathogenetic roles in nonalcoholic fatty liver disease (NAFLD) and hyperandrogenic states like polycystic ovary syndrome (PCOS). We tested the hypothesis that alanine aminotransferase (ALT), a marker of NAFLD, is associated with endocrine and metabolic abnormalities in women with normal ALT. METHODS AND RESULTS Fasting glucose, insulin, total testosterone, DHEA-S, 17-hydroxyprogesterone, prolactin, leptin, soluble leptin receptor, free leptin index (FLI), lipid profile, ALT, gonadotropins, and sex hormone binding globulin (SHBG) were measured in 200 women aged 18-48 years. Beta cell function (%B), insulin sensitivity (%S) and insulin resistance were calculated using the homeostasis model assessment (HOMA-IR). Ninety-two women had PCOS (Rotterdam criteria); 64 had idiopathic hyperandrogenism; 44 were normal controls. ALT showed significant positive correlations with waist circumference (WC), systolic blood pressure, glucose, leptin, FLI, triglycerides, HOMA-IR and androgens and significant inverse correlations with leptin receptor, HDL-C, %S and SHBG. Correcting for WC and fat% showed that the associations between ALT and glucose, HOMA-IR, testosterone and free androgen index are independent of obesity. Binary logistic regression analyses showed significant association of ALT with PCOS and hyperandrogenemia. ALT ≥ 18 IU/L showed significant association with PCOS with Odds Ratio = 2.28 (95% Confidence Interval = 1.03-5.08), p = 0.043. CONCLUSIONS In women of reproductive age, normal levels of ALT are associated with metabolic and androgenic phenotypes. We suggest a paradigm shift and extension of the routine use of ALT beyond the diagnosis of liver disease.

Abstract
This review examines racial and ethnic disparities in reproductive health focusing on 3 key topical areas: (1) infertility, (2) polycystic ovarian syndrome, and (3) reproductive aging. We report that an increasing body of knowledge points toward reduced infertility access and in vitro fertilization outcomes in Asian, black, and Hispanic women compared with white women. There are differences in the reproductive and metabolic phenotypes of Asian, black, and Hispanic women presenting with the polycystic ovarian syndrome compared with white women. Reproductive aging differences appear to exist in all racial and ethnic groups. Awareness of racial and ethnic disparities is critical to a complete understanding of the health issues facing women of reproductive age.

Abstract
BACKGROUND Hirsutism is the presence of excess body or facial terminal (coarse) hair growth in females in a male-like pattern, affects 5-15% of women, and is an important sign of underlying androgen excess. Different methods are available for the assessment of hair growth in women. METHODS We conducted a literature search and analyzed the published studies that reported methods for the assessment of hair growth. We review the basic physiology of hair growth, the development of methods for visually quantifying hair growth, the comparison of these methods with objective measurements of hair growth, how hirsutism may be defined using a visual scoring method, the influence of race and ethnicity on hirsutism, and the impact of hirsutism in diagnosing androgen excess and polycystic ovary syndrome. RESULTS Objective methods for the assessment of hair growth including photographic evaluations and microscopic measurements are available but these techniques have limitations for clinical use, including a significant degree of complexity and a high cost. Alternatively, methods for visually scoring or quantifying the amount of terminal body and facial hair growth have been in use since the early 1920s; these methods are semi-quantitative at best and subject to significant inter-observer variability. The most common visual method of scoring the extent of body and facial terminal hair growth in use today is based on a modification of the method originally described by Ferriman and Gallwey in 1961 (i.e. the mFG method). CONCLUSION Overall, the mFG scoring method is a useful visual instrument for assessing excess terminal hair growth, and the presence of hirsutism, in women.

Abstract
OBJECTIVES To quantify the three-dimensional (3D) ultrasound characteristics of ovaries in Chinese women with polycystic ovarian syndrome (PCOS) and to compare these with previous data on a Caucasian cohort with PCOS. METHODS 3D pelvic ultrasound was performed in 40 Chinese women with PCOS and 40 controls. Ovarian volume, stromal volume and echogenicity, and antral follicle count (AFC) were measured and ovarian blood flow was quantified using both 3D power Doppler and two-dimensional (2D) pulsed wave Doppler. These data were compared with previously published data on a Caucasian cohort with PCOS. RESULTS Compared with controls, women with PCOS had a higher AFC (median (range), 15 (11-30) vs. 5.5 (1-10) per ovary, P < 0.01), ovarian volume (12.32 (8.10-16.16) mL vs. 5.64 (2.62-8.81) mL, P < 0.01) and stromal volume (9.74 (6.44-13.56) mL vs. 4.07 (1.52-6.67) mL, P < 0.01) but were comparable in stromal echogenicity and ovarian blood flow as measured by 3D power Doppler or 2D pulsed wave Doppler indices. However, in comparison with a previously reported Caucasian cohort with PCOS, the ovaries of Chinese women with PCOS had a significantly smaller stromal volume (median (range), 9.74 (6.44-13.56) mL vs. 10.79 (5.65-17.12) mL, P < 0.05), were less echogenic as reflected in a lower mean gray value (22.43 (13.13-35.50) vs. 32.36 (19.35-53.71), P < 0.01), and had reduced ovarian blood flow as reflected in a lower flow index (30.19 (23.32-44.88) vs. 33.54 (21.88-51.65), P < 0.05). CONCLUSION Based on 3D ultrasound measurements, Chinese women with PCOS have an increased stromal volume compared with controls. However, their stromal volume, echogenicity and vascularity is significantly lower than that in Caucasian women with PCOS. The possible etiology for these differences is discussed.

Abstract
OBJECTIVE To review all available data and recommend a definition for polycystic ovary syndrome (PCOS) based on published peer-reviewed data, whether already in use or not, to guide clinical diagnosis and future research. DESIGN Literature review and expert consensus. SETTING Professional society. PATIENTS None. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) A systematic review of the published peer-reviewed medical literature, by querying MEDLINE databases, to identify studies evaluating the epidemiology or phenotypic aspects of PCOS. RESULT(S) The Task Force drafted the initial report, following a consensus process via electronic communication, which was then reviewed and critiqued by the Androgen Excess and PCOS (AE-PCOS) Society AE-PCOS Board of Directors. No section was finalized until all members were satisfied with the contents, and minority opinions noted. Statements were not included that were not supported by peer-reviewed evidence. CONCLUSION(S) Based on the available data, it is the view of the AE-PCOS Society Task Force that PCOS should be defined by the presence of hyperandrogenism (clinical and/or biochemical), ovarian dysfunction (oligo-anovulation and/or polycystic ovaries), and the exclusion of related disorders. However, a minority considered the possibility that there may be forms of PCOS without overt evidence of hyperandrogenism, but recognized that more data are required before validating this supposition. Finally, the Task Force recognized and fully expects that the definition of this syndrome will evolve over time to incorporate new research findings.

Abstract
It is estimated that as many as 1.4 million Canadian women may be afflicted with polycystic ovary syndrome (PCOS). Although PCOS is heralded as one of the most common endocrine disorders occurring in women, its diagnosis, management, and associated long-term health risks remain controversial. Historically, the combination of androgen excess and anovulation has been considered the hallmark of PCOS. To date, while these symptoms remain the most prevalent among PCOS patients, neither is considered an absolute requisite for the syndrome. Inclusion of ultrasonographic evidence of polycystic ovaries as a diagnostic marker has substantially broadened the phenotypic spectrum of PCOS, yet much debate surrounds the validity of these newly identified milder variants of the syndrome. Difficulty in resolving the spectrum of PCOS stems from the continued use of inconsistent and inaccurate methods of evaluating androgen excess, anovulation, and polycystic ovaries on ultrasound. At present, there is no clear-cut definition of biochemical hyperandrogenemia, particularly since we depend on poor laboratory standards for measuring androgens in women. Clinical signs of hyperandrogenism are ill-defined in women with PCOS, and the diagnosis of both hirsutism and polycystic ovarian morphology remains alarmingly subjective. Lastly, there is an inappropriate tendency to assign ovulatory status solely on the basis of menstrual cycle history or poorly timed endocrine measurements. In this review, we elaborate on these limitations and propose possible resolutions for clinical and research settings. By stimulating awareness of these limitations, we hope to generate a dialogue aimed at solidifying the evaluation of PCOS in Canadian women.

Abstract
Background Polycystic ovary syndrome (PCOS) is a common endocrine condition affecting women of reproductive age and characterized by chronic anovulation, hyperandrogenism, and polycystic ovaries. There are no published data on this syndrome in Libyan patients. Aims and objectives To assess the frequency of clinical and biochemical features of PCOS in our patient population, and to compare this with data collected in other parts of the world. Subjects and methods A retrospective analysis of patient records at the endocrine clinic in Benghazi was undertaken. Patient inclusion was according to Rotterdam ESHRE/ASRM criteria. Clinical features, associated diseases, family history, hormone levels, and ultrasonography results were analyzed. Results The mean age of the 318 PCOS patients at presentation was 25.8 years (range 15–44 years), and the majority (67%) were 20–29 years old at presentation. Of all patients, 57% were obese (BMI≥30), 93% had oligo-/amenorrhea, 91% were hirsute, and 74% had ultrasound features of polycystic ovaries. Diabetes mellitus was diagnosed in 9% of all PCOS patients and hypertension in 4%. Total serum testosterone was elevated in 26% of the patients, and serum prolactin was elevated in 31%. Thyroid disease was noted among 5.3% of the patients, and a history of diabetes or hypertension among first-degree relatives was seen in (16%) and (8%) of the patients respectively. Conclusion Chronic anovulation and hirsutism are the dominant features of PCOS in our patient population. More than half were obese, and the prevalence of diabetes, hypertension and thyroid disease in our patients seemed to be underestimated in comparison to other parts of the world.

Abstract
PURPOSE OF REVIEW This review clarifies the challenges facing investigators in the search for polycystic ovarian syndrome candidate genes. RECENT FINDINGS Evidence for fibillin 3 has emerged as a polycystic ovarian syndrome candidate gene. The sex hormone binding gene also shows promise, as does evidence for fetal programming and X-chromosome inactivation. SUMMARY As with many complex disorders, the heritability of polycystic ovarian syndrome has eluded investigators. Although familial aggregation studies have demonstrated clearly a genetic component to the syndrome, simple Mendelian models do not characterize its mode of inheritance. Instead, multiple loci and epigenetic modification may play a role in the phenotype. The candidate gene approach relies upon improved statistical and technological methods to analyze potential genes based on biologic plausibility. Pathways that affect steroidogenesis, insulin resistance, gonadotropin function, and obesity provide potential genes for investigation. Obstacles such as phenotypic variability, lack of a male phenotype, multiple attempts at analysis, and small sample sizes hamper these efforts. Nevertheless, great care must be taken to apply rigorous standards as we proceed with genetic studies. In addition to increasing our knowledge of common disorders, potential benefits include personalized medicine, with pharmacogenetics allowing therapies tailored to the individual.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women in the reproductive age and is a major cause of anovulation, hyperandrogenism and infertility. Since obesity and insulin resistance are predominant features of women with PCOS, a variety of metabolic disturbances are associated. There is a marked increase in the risk of developing type-2 diabetes in these patients and a majority of women with PCOS will subsequently harbour an enhanced cardiovascular risk.

Abstract
Polycystic ovaries syndrome (PCOS) is one of the most common female hormonal disorders. Its multiple components--reproductive, metabolic, neoplasic and cardiovascular--have a major impact on the public health. Androgen excess and resistance to insulin, probably from genetic origin, are responsible for most of the clinical symptomatology. Resistance to insulin seems to be accompanied by a greater risk of glucose intolerance, type 2 diabetes, lipidic anomalies and can involve the development of cardiovascular diseases. In addition, sleep apnea syndrome is more progressively described in PCOS. Infertility, menses disorders and hirsutism often push these patients to consult their physician. A better understanding of the physiopathological mechanisms led to the emergence of new therapeutic options increasing the sensitivity to insulin. Besides the pregnancy wishes, cares aim to attenuate the marks of the hyper-androgenism (hormonal treatment and cosmetic) and to correct cardiovascular, respiratory and gynaecological risk factors. In case of infertility by anovulation, cares must be performed by trained experts to minimize the risk of ovarian hyper-stimulation syndrome and multiple pregnancies. A gradation from loose weight to clomiphene citrate ovulation induction, ovarian drilling, low dose gonadotropin, in vitro fertilisation, or in vitro maturation of oocytes should bring back good reproduction potential.

Abstract
Polycystic ovarian syndrome is a complex disorder with multiple factors affecting its etiology. Elucidation of specific genes and mode of inheritance remains a significant challenge. Linkage and association studies have resulted in over 50 candidate genes as a source of heritable predisposition; however, small sample sizes and failure to reproduce results have hindered efforts. In addition, low fecundity, lack of a male phenotype, and variation of diagnostic criteria represent unique challenges to discovery of polycystic ovarian syndrome genes. A concerted effort will be necessary to conclusively rule in or rule out candidate genes.

Abstract
OBJECTIVE The Androgen Excess Society (AES) charged a task force to review all available data and recommend an evidence-based definition for polycystic ovary syndrome (PCOS), whether already in use or not, to guide clinical diagnosis and future research. PARTICIPANTS Participants included expert investigators in the field. EVIDENCE Based on a systematic review of the published peer-reviewed medical literature, by querying MEDLINE databases, we tried to identify studies evaluating the epidemiology or phenotypic aspects of PCOS. CONSENSUS PROCESS The task force drafted the initial report, following a consensus process via electronic communication, which was then reviewed and critiqued by the AES Board of Directors. No section was finalized until all members were satisfied with the contents and minority opinions noted. Statements that were not supported by peer-reviewed evidence were not included. CONCLUSIONS Based on the available data, it is the view of the AES Task Force on the Phenotype of PCOS that there should be acceptance of the original 1990 National Institutes of Health criteria with some modifications, taking into consideration the concerns expressed in the proceedings of the 2003 Rotterdam conference. A principal conclusion was that PCOS should be first considered a disorder of androgen excess or hyperandrogenism, although a minority considered the possibility that there may be forms of PCOS without overt evidence of hyperandrogenism but recognized that more data are required before validating this supposition. Finally, the task force recognized, and fully expects, that the definition of this syndrome will evolve over time to incorporate new research findings.

Abstract
A (tttta)n microsatellite polymorphism in the promoter of CYP11a gene was investigated in 201 Chinese Han women with polycystic ovary syndrome (PCOS) and 147 control women. The 6/6 genotype was defined with significant difference of CYP11a polymorphism between women with PCOS and control women, and associated with greater BMI in PCOS patients, suggesting a certain role of the six-repeat allele variant in the pathogenesis of Chinese women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a complex and heterogeneous disorder that presents a challenge for clinical investigators. It is the most common endocrine disorder of reproductive-aged women, yet the optimal therapeutic approach is unknown because the pathophysiological and molecular basis of the syndrome is not fully understood. Currently, the treatment is targeted to the patient's primary complaint. Treatment strategies focus on the reduction of clinical manifestations of hyperandrogenism (e.g., hirsutism), restoration of regular menses and achieving pregnancy. Pharmacological agents available for the treatment of hirsutism include androgen suppressors and peripheral androgen blockers. Combined oral contraceptive pills are the most commonly used androgen suppressor and the treatment of choice for menstrual dysfunction in PCOS patients who do not desire pregnancy. The first-line treatment for infertility in PCOS is clomiphene-citrate, whereas parenteral gonadotropins are commonly used in clomiphene-resistant patients. The benefits of insulin-sensitising agents for PCOS patients have become increasingly clear over the last decade. Metabolic disturbances associated with PCOS appear to have important long-term health implications and require further attention. This review summarises the current and emerging therapeutic strategies for the management of PCOS.

Abstract
Current data supporting the effectiveness of metformin as a fertility treatment for women with polycystic ovary syndrome have been misinterpreted. Still unproven for women with polycystic ovary syndrome is, first, whether metformin adds to the standard first-line fertility management in all women, second, whether metformin is an effective fertility treatment for overweight women, and third, the relative fertility efficacy of metformin and clomiphene citrate as a first-line treatment in women with a lower body weight. The PCOSMIC (polycystic ovary syndrome: metformin for infertility with clomiphene) trial is an ongoing New Zealand multicentre double-blind placebo-controlled parallel randomised trial assessing these questions.

Abstract
To investigate the association of single-nucleotide polymorphisms (SNPs) in exon 17 of the insulin receptor (INSR) gene with insulin resistance and INSR beta-subunit expression in polycystic ovary syndrome (PCOS) patients, a case-control study was carried out in an academic endocrinology clinic of China. One hundred and nine Chinese patients with PCOS and 107 healthy Chinese women as control were recruited. Their leukocytes and red blood cells were separated from blood samples, for SNP analysis with single-stranded conformation polymorphism and for the INSR beta-subunit expression detection by western blot analysis, respectively. A novel T/C SNP at codon Cys1008 (position 3128 of NM_000208) of INSR was found in two allele genotypes, i.e. the homozygous CC and the heterozygous TC. A higher frequency of the mutant homozygous CC was observed in the PCOS women with PCOS than that in the controls (21.1 versus 5.6%, P < 0.01). In contrast with the women with wild-type genotype, a significantly lower insulin sensitivity index in the women with each of the two mutant genotypes was revealed (CC: 0.335 +/- 0.026/TC: 0.346 +/- 0.027 versus TT: 0.367 +/- 0.029, P < 0.05). No relationship was found between the novel SNP and the INSR beta-subunit expression. We concluded that the novel T/C SNP at codon Cys1008 of INSR is associated with decreased insulin sensitivity in Chinese women with PCOS and that the association is not by the change of synthesis or secretion of INSR beta-subunit, but most possibly by the effects of this novel SNP on the function of INSR beta-subunit.

Abstract
Compared with normal women, adults with polycystic ovarian syndrome (PCOS) require higher progesterone (P) concentrations to inhibit GnRH (LH) pulse frequency, which contributes to persistently rapid GnRH pulses and elevated LH levels in PCOS. To explore the origin of this abnormality, we assessed hypothalamic sensitivity to P feedback in nine normal controls and 11 hyperandrogenemic (HA) adolescents. Subjects first underwent frequent blood sampling for 11 h to assess baseline LH pulse frequency. Thereafter, oral estradiol and micronized P were given for 7 d to achieve mean estradiol and P levels of 143 +/- 16 pg/ml (524 +/- 60 pmol/liter) and 7.8 +/- 0.7 ng/ml (24.9 +/- 2.3 nmol/liter), respectively. LH pulse frequency was then reassessed. On d 7, the slope of the percent reduction of LH pulses per 11 h as a function of the d 7 P concentration was less in the HA group compared with controls (P = 0.02) despite similar P levels. LH pulse frequency was suppressed in all NC (mean, 7.0 to 3.4 pulses/11 h), but was unchanged in six of the HA girls (mean, 8.3 to 7.5 pulses/11 h). In contrast, in the other five HA adolescents, P induced similar slowing of LH pulses to that seen in NC (mean, 10.0 to 5.0 pulses/11 h). Baseline free testosterone levels were similar in both HA groups; the only observed difference between these HA groups is that the P-suppressible subjects were all of Hispanic descent. These data suggest that hyperandrogenemia during adolescence is variably associated with decreased sensitivity to P, which may have a partially genetic basis.

Abstract
The genetic mechanisms underlying functional hyperandrogenism and the polycystic ovary syndrome (PCOS) remain largely unknown. Given the large number of genetic variants found in association with these disorders, the emerging picture is that of a complex multigenic trait in which environmental influences play an important role in the expression of the hyperandrogenic phenotype. Among others, genomic variants in genes related to the regulation of androgen biosynthesis and function, insulin resistance, and the metabolic syndrome, and proinflammatory genotypes may be involved in the genetic predisposition to functional hyperandrogenism and PCOS. The elucidation of the molecular genetic basis of these disorders has been burdened by the heterogeneity in the diagnostic criteria used to define PCOS, the limited sample size of the studies conducted to date, and the lack of precision in the identification of ethnic and environmental factors that trigger the development of hyperandrogenic disorders. Progress in this area requires adequately sized multicenter collaborative studies after standardization of the diagnostic criteria used to classify hyperandrogenic patients, in whom modifying environmental factors such as ethnicity, diet, and lifestyle are identified with precision. In addition to classic molecular genetic techniques such as linkage analysis in the form of a whole-genome scan and large case-control studies, promising genomic and proteomic approaches will be paramount to our understanding of the pathogenesis of functional hyperandrogenism and PCOS, allowing a more precise prevention, diagnosis, and treatment of these prevalent disorders.
