OBJECTIVE: Polycystic ovary syndrome (PCOS) is characterized by ovarian dysfunction. Although the role of leptin in the control of reproduction is unclear, it may be involved in the control of ovulation. The aim of this cross-sectional study was to determine the relationship between circulating leptin concentrations, and anthropometric, metabolic and endocrine variables as well as to examine a possible role of leptin in ovarian dysfunction associated with PCOS. DESIGN: Prospective observational study. METHODS: Seventy-one subjects with PCOS and 23 body mass index (BMI)-matched control subjects were recruited from infertility clinics. The association between serum leptin concentrations and the above variables was measured outwith the luteal phase. A subgroup of 24 PCOS subjects underwent more frequent blood sampling to monitor follicular growth and ovulation. The association between variables was measured by univariate, multivariate and partial correlation analyses. RESULTS: Serum leptin concentrations were not different in subjects with PCOS and controls, and were strongly associated with BMI in both groups. Twelve patients ovulated during the study period. There was no significant difference in serum leptin concentrations between ovulatory and anovulatory subjects. The relationship between BMI and leptin was similar in both groups. CONCLUSION: The results indicated that circulating leptin concentrations relate principally to total body fat in subjects with PCOS and controls, and that this is not associated with the facility for follicular development and ovulation in these patients.

Objective: This review examines the existing evidence for the relationship between borderline personality disorder and polycystic ovary syndrome, and to identify commonalities in etiological mechanisms of borderline personality disorder and polycystic ovary syndrome that might explain the relationship between these seemingly disparate disorders. Methods: A search of Medline, EMBASE and Cochrane Central was undertaken on 5 December 2016 to identify studies investigating women with borderline personality disorder and polycystic ovary syndrome (or symptoms and markers specific to polycystic ovary syndrome). Results: Nine studies were identified, including three cross-sectional studies investigating symptoms of polycystic ovary syndrome in women with borderline personality disorder, two cross-sectional and one cohort study examining the prevalence of psychiatric diagnoses in women with polycystic ovary syndrome and three case reports of comorbid borderline personality disorder and polycystic ovary syndrome. Conclusion: Overall, the literature shows women with borderline personality disorder to have higher than expected serum androgen levels and incidence of polycystic ovaries, which can be key features of polycystic ovary syndrome. However, this research is still in its infancy, which limits our understanding of this potential comorbid phenomenon. Given the emerging anecdotal and empirical evidence to date, a theoretical discussion of the potential psychoneuroendocrinological mechanism underlying the borderline personality disorder and polycystic ovary syndrome comorbidity is provided. Further rigorous studies using standardized diagnostic criteria for polycystic ovary syndrome are warranted. Specifically, the use of prospective controlled cohort studies may be able to determine the causality and temporality of observed comorbid borderline personality disorder and polycystic ovary syndrome.

Abstract Polycystic ovary syndrome (PCOS) is associated with chronic anovulation, hyperandrogenemia, insulin resistance (IR)/hyperinsulinemia, and a high incidence of obesity. Thus, PCOS serves as a useful model to assess the role of IR and chronic endogenous insulin excess on leptin levels. Thirty-three PCOS and 32 normally cycling (NC) women of similar body mass index (BMI) were studied. Insulin sensitivity (SI) was assessed by rapid ivGTT in a subset of 28 PCOS and 29 NC subjects; percent body fat was determined by dual-energy x-ray absorptiometry (DEXA) in 14 PCOS and 17 NC. Fasting (0800 h) and 24-h mean hourly insulin levels were 2-fold higher (P < 0.0001), and SI was 50% lower (P = 0.005) in PCOS than in NC, while serum androstenedione (A), testosterone (T), 17-α hydroxyprogesterone (17OHP), and estrone (E1) levels were elevated (P < 0.0001), and sex hormone-binding globulin (SHBG) levels were decreased (P < 0.01). Twenty-four hour LH pulse frequency, mean pulse amplitude, and mean LH levels were elevated in PCOS (P < 0.001) as compared with NC. Serum leptin levels for PCOS (24.1 ± 2.6 ng/mL) did not differ from NC (21.5 ± 3.5 ng/mL) and were positively correlated with BMI (r = 0.81) and percent body fat (r = 0.91) for the two groups (both P < 0.0001). Leptin levels for PCOS and NC correlated positively with fasting and 24-h mean insulin levels (r = 0.81, P < 0.0001 for both PCOS and NC) and negatively with SI and SHBG levels. Leptin concentrations for PCOS, but not NC, correlated positively with 24-h mean glucose levels and inversely with 24-h mean LH levels and 24-h mean LH pulse amplitude. Leptin levels were not correlated with estrogen or androgen levels for either PCOS or NC, although leptin levels were positively related to the ratios of E1/SHBG and E2/SHBG for both PCOS and NC and to the ratio of T/SHBG for PCOS only. In stepwise multivariate regression with forward selection, only 24-h mean insulin levels contributed significantly (P < 0.01) to leptin levels independent of BMI and percent body fat for both PCOS and NC. Given this relationship and the presence of 2-fold higher 24-h mean insulin levels in PCOS, the expected elevation of leptin levels in PCOS was not found. This paradox may be explained by the presence of adipocyte IR specific to PCOS, which may negate the stimulatory impact of hyperinsulinemia on leptin secretion, a proposition requiring further study.

The aim of this study was to investigate the prevalence of insulin resistance (IR) according to the phenotypic subgroups of polycystic ovary syndrome (PCOS) and to determine the associations of TSH levels and body mass index (BMI) with IR in infertile women with PCOS. In this cross-sectional study, we included 400 infertile women with a diagnosis of PCOS according to Rotterdam criteria who were referred to the infertility clinic of amir-al-Momenin University Hospital from April 2018- to January 2020. They were classified into four different phenotypic subgroups according to ESHRE guidelines. The homeostasis model (HOMA-IR) was used to measure IR. The prevalence of insulin resistance was 39.3% in infertile women with PCOS. Among women with PCOS, the commonest phenotype was type I (68%), with type II (18.2%), type III (8.8%), and type IV (5%), respectively. Furthermore, there was no significant difference in the prevalence of IR among different phenotypes of PCOS. Logistic regression analysis showed that the chance of insulin resistance was higher in overweight (OR: 1.76, 95% CI: 1.07, 2.88, P=0.024) and obese PCOS women (OR: 3.25, 95% CI: 1.86, 5.67, P<0.001) compared with those who were normal or underweight. Moreover, the chance of IR was higher in PCOS women with TSH ≥2.5 μIU/ml as compared with those who had TSH <2.5 μIU/ml (OR: 2.00, 95% CI: 1.18, 3.40, P<0.001). Insulin resistance is a prevalent disorder among infertile Iranian women with PCOS BMI, and serum levels of TSH ≥2.5 μIU/ml are independent predictors of IR.

ABSTRACT Polycystic Ovary Syndrome (PCOS) is endocrine reproductive disorder which causes oligomenorrhea/ amenorrhea, infertility, type II diabetes. The present study aims in CYP19A1 polymorphism rs700519 (C/T) identification that elevates androgen among PCOS females in Quetta, Pakistan. Cross-sectional study involved enrollment of 100 control and 100 affected females. Blood samples were collected for genetic and hormonal analysis. The samples were amplified via ARMS PCR and analyzed by sequencing. The frequency of CC genotype in control and PCOS group was 48 percent and 33 percent. For CT, it was 52 percent and 67 percent. In control group, the allele frequency for C and T was 0.74 and 0.26. In PCOS group, it was 0.67 and 0.33 for C and T, respectively. The Pearson Chi-Square p=0.031 (p<0.05) at 95% Confidence Interval inferred a significant difference between the observed genotypes. The study inferred that CT genotype is a risk factor for PCOS progression in the population of Quetta.

This study was conducted at the Fertility Center at Al-Sadr Teaching Hospital in Najaf Governorate from 16/10/2016 to 10/3/2017 to determine the relationship between thyroid disorders and polycystic ovary syndrome in women of reproductive age. There was no significant difference in body mass and age for thyroid function. The study as well showed not significant difference in T3 and T4 levels when comparing the two groups, but there was a significant difference (P less than 0.05) in the TSH level, which is higher in the patients. It is concluded that there is a relationship between thyroid disorders and PCOS due to increased TSH in women with the syndrome.

Recent research suggests that women with polycystic ovary syndrome (PCOS) may have a higher prevalence of asthma. However, there are no epidemiological studies aimed primarily at exploring the relationship between PCOS and asthma, and the effect of body mass index (BMI) on this association.This study is a cross-sectional analyses of data from the Australian Longitudinal Study on Women's Health, a large, community-based, prospective study to examine the association between PCOS and asthma in women aged 28–33 years (n=478 PCOS and n=8134 controls).The prevalence of asthma was 15.2% in women with PCOS and 10.6% in women without PCOS (p=0.004). Women with PCOS who had asthma had a trend for a higher BMI compared with women without asthma (29.9±0.9 versus 27.7±0.4 kg·m−2; p=0.054). Women without PCOS who had asthma had a higher BMI compared with women without asthma (26.4±0.2 versus 24.9±0.1 kg·m−2; p<0.001). After adjusting for age, BMI and smoking status, PCOS was associated with increased odds of asthma (odds ratio 1.34, 95% CI 1.004–1.79; p=0.047).This study showed both PCOS status and overweight/obese status were independently associated with asthma. Further prospective studies are required to explore the possible mechanisms underpinning the association between asthma and PCOS.

Background: Polycystic ovary syndrome (PCOS) increases the risk of metabolic syndrome (MetS). Insulin resistance (IR) plays a major role in the pathophysiology of both PCOS and MetS. Objective: This study was designed to compare the prevalence of MetS among different phenotypes of PCOS and its relationship with androgenic components. Materials and Methods: 182 participants eligible for this five-group comparative study were selected by convenience sampling method. They were classified according to the Rotterdam criteria: clinical and/or biochemical hyperandrogenism (H) + PCOS on ultrasound (P) + ovulation disorders (O) (n = 41), clinical and/or biochemical H + PCOS on P (n = 33), PCOS on P + O (n = 40), clinical and/or biochemical H + O (n = 37), and control (without PCOS) (n = 31). MetS was measured based on the National Cholesterol Education Program Adult Treatment Panel III criteria. Androgenic components included free androgen- index (FAI), total-testosterone (TT) level and sex-hormone-binding-globulin (SHBG). Results: A significant difference was observed between the study groups in terms of MetS prevalence (p = 0.01). In phenotype H+P+O, there was a statistically significant positive association between TG and TT, and a significant negative association between SBP and DBP with SHBG. In phenotype O+P, WC was inversely associated with SHBG. In phenotype H+O, FBS and TG were positively associated with FAI but HDL was inversely associated with FAI. Moreover, WC and DBP were positively associated with TT in phenotype H+O. No associations were detected between MetS parameters and androgenic components in other PCOS subjects (phenotype H+P) and in the control group. TT was significantly higher in the PCOS group suffering from MetS (p = 0.04). Conclusion: According to the research results, hyperandrogenic components are potent predictors of metabolic disorders. Thus, we suggest that MetS screening is required for the prevention of MetS and its related complications in PCOS women. Key words: Polycystic ovary syndrome, Metabolic syndrome, Hyperandrogenism.

Objectives: Polycystic ovary syndrome (PCOS) is considered as one of the causes of infertility. Anti-Mullerian hormone (AMH) is 2-3 times higher in patients with the PCOS compared to others. The present study aimed to survey the association between basal AMH levels and ovarian response in infertile PCOS patients. Materials and Methods: In this cross-sectional study, 70 infertile PCOS women were enrolled referring to Milad Infertility Center (Mashhad, Iran) from May 2011 to April 2012. The basal blood level of AMH was evaluated. The patients received 5 mg of letrozole from the fifth cycle day (for 5 days) and then received 150 units of gonal F in the form of the recombinant follicle-stimulating hormone (FSH) on the ninth day of the cycle. Five thousand units of human chorionic gonadotropin (hCG) were prescribed for the patients who had one follicle of ≥ 18mm. Then, they should have had intercourse 36 hours later. After ovulation induction (OI) on the 10th cycle day, the second serum sample of AMH was taken. Results: Changes of AMH did not have a significant relationship with the ovarian response, namely, it was lower in patients with positive ovarian response compared to those without any ovarian response. In addition, the basal level of AMH in patients with a positive response (3.91 ± 2.14) had no significant difference with the secondary AMH (3.27 ± 2.39) after the OI (P = 0.19). Conclusions: Generally, the AMH was not a predictor of ovarian response in PCOS patients and the amount of AMH reduced after the treatment. This effect was maybe related to letrozole and gonadotropin.
