Abstract Objective Polycystic ovary syndrome (PCOS) can be divided into different subtypes, including insulin resistance (IR) and hyperandrogenism (HA). Asprosin is a novel hormone associated with IR; however, the role of asprosin in women with PCOS has not been investigated. Thus, the aim of this study was to investigate the relationship between serum asprosin levels and PCOS subtypes. Methods Ninety-three women with PCOS and 77 healthy women as controls were selected for this study. Clinical and laboratory data were compared between the PCOS group and the control group. The PCOS group was further divided into subgroups: 1) women with or without HA (PCOS HA and PCOS NHA, respectively); 2) women with or without IR (PCOS IR and PCOS NIR, respectively). Serum asprosin was measured by ELISA. Results Serum asprosin levels showed no significant difference between the PCOS and control groups. However, it was significantly lower in the PCOS HA and IR groups compared to the respective PCOS NHA and NIR groups (P < .05). In the PCOS group, serum asprosin was negatively correlated with body mass index, luteinizing hormone, testosterone, basal antral follicles, fasting insulin, Homeostatic Model Assessment of Insulin Resistance, and triglycerides. After adjusting for BMI, the correlations were not significant and asprosin was only positively correlated with prolactin (r = 0.426, P < .001). Conclusions Our study shows that women with PCOS HA or IR exhibit significantly lower serum asprosin levels compared to controls, and the lower asprosin level directly correlated with PRL level.

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders of women in the childbearing period. However, its pathophysiology is still unclear. Certain polymorphisms of the luteinizing hormone/choriogonadotropin receptor (LHCGR) genes may lead to changes in the bioactivity of this hormone. The important functional role of LHCGR in the metabolism of androgen and ovulation, the LHCGR gene variant, may be related to the risk of PCOS. AIM: The aim of this study was to evaluate the association between LHCGR Ins18LQ gene polymorphism and PCOS. METHODS: A case–control study was performed in women with PCOS and non-PCOS from May 2019 to October 2019 in HFC IVF Center. We included 50 women with PCOS and 50 healthy controls. Polymorphism of the LHCGR (ins18LQ) gene was genotyped using polymerase chain reaction-restriction fragment length polymorphism. RESULTS: From this study, we found that there was no significant difference in the proportion of ages between the groups (p > 0.05). There were significant differences in the characteristics of body mass index, FSH level, LH level, and LH/FSH ratio between the PCOS and control groups (p < 0.05). We also found that the proportion of heterozygote variant non-ins/ins was higher in the PCOS group compared to the control group, but there was no significant difference between the polymorphisms of the non-ins and non-nonins variants between the PCOS and control groups (p = 0.269). The frequency of ins alleles was higher in the PCOS group compared to the control group. CONCLUSION: There was no significant association between LHCGR ins18LQ gene polymorphism and PCOS.

ObjectivesPolycystic ovary syndrome (PCOS) is the most common endocrinopathy of women at reproductive age. Although the aetiology of PCOS remains unclear, potential effects of environmental endocrine-disrupting compounds on the development of PCOS have drawn increasing attention. The aim of the current study was to examine the association between triclosan (TCS) and PCOS, and explore possible mechanisms on how TCS may contribute to the development of clinical manifestations of PCOS.DesignCross-sectional study.SettingThis study was conducted in one tertiary-level hospital located in Zhejiang, China.ParticipantsA total of 674 infertile women at 18–45 years of age were recruited in 2014–2015. Participants with (n=84) and without (n=212) PCOS with urinary TCS concentration available were included in the analyses.MethodsUrinary TCS concentration was measured using a high-performance liquid chromatography–electrospray ionisation tandem mass spectrometry. Logistic regression model was used to examine the association between TCS and PCOS. Fractional polynomial regression models were built to fit the potential non-linear relationship between TCS concentrations and luteinising hormone (LH) and LH/follicle stimulate hormone (FSH).ResultsThe PCOS group had significantly higher level of TCS concentration than the non-PCOS group (the median of TCS (IQR), μg/g creatinine: 1.49 (0.68–3.80) vs 1.06 (0.52–3.02), p=0.0407). Compared with the lowest tertile, the highest tertile of TCS concentration was associated with an increased odd of PCOS (OR 2.12, 95% CI 1.12 to 3.99). After adjusting for potential confounders, the significant association remained (OR 1.99, 95% CI 1.05 to 3.79). Positive relationships were found between TCS levels and LH and LH/FSH ratio in non-PCOS participants.ConclusionsTCS exposure at a relatively low level is associated with PCOS in Chinese women. Further epidemiological studies are needed to confirm our finding, which may have important public health implications.

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.

Background: Menstrual irregularities may predict over adverse consequences in polycystic ovary syndrome (PCOS).Objective: To observe the relation of variants of menstrual cycles with clinical and biochemical features of PCOS.Methods: This cross-sectional study encompassed 200 PCOS women diagnosed by Rotterdam criteria and 120 age-matched healthy controls. Subgroups were classified according to menstrual cycle length as: polymenorrheic (<21 days), eumenorrheic (21-35 days), oligomenorrheic (36 days-3 months) and amenorrheic (>3 months). Glucose was measured by glucose oxidase, lipid by glycerol phosphate dehydrogenenase-peroxidase and all hormones by chemiluminescent immuno-assay method.Results: Around 86% of PCOS patients had menstrual irregularity, among which 75% had oligomenorrhea followed by amenorrhea (9%) and polymenorrhea (2%). All the subgroups of PCOS patients (polymenorrhea excluded from further analyses) had significantly poor metabolic manifestations than the control namely insulin resistance (IR), impaired glycaemic status, general and central obesity, metabolic syndrome and dyslipidaemia. Acanthosis nigricans (AN), hyperandrogenemia (HA) and IR had significant predictive association with PCOS patients with both irregular [OR (95% CI)- AN: 21.994 (6.427, 75.267), p<0.001; HA: 27.735 (8.672, 88.704), p<0.001; IR: 7.268 (2.647, 19.954), p<0.001] and regular cycle [AN: 16.449 (3.830, 70.643), p<0.001; HA: 24.635 (6.349, 95.590), p<0.001; IR: 6.071 (1.658, 22.234), p=0.006] in reference to control group. None of the variables had significant predictive associations with irregular cycle in reference to regular cycle in patients with PCOS.Conclusion: Oligomenorrhea was the most common variant of menstrual irregularity in PCOS patients. All menstrual variants including eumenorrhea had similar manifestations in PCOS women, but poorer than controls.International Journal of Human and Health Sciences Vol. 06 No. 01 January’22 Page: 96-103

Abstract BackgroundLifestyle management has been proved to improve both metabolic and reproductive outcomes for women with polycystic ovary syndrome (PCOS). In China, WeChat has become the most popular social media platform. Previous studies have confirmed the effectiveness of WeChat in health intervention and its potential to improve health behaviours. Therefore the present study tried to investigate the efficacy of online education through WeChat public account on the lifestyle interventions of women with PCOS.MethodsWe set up a cross-sectional study between January 2020 and July 2020. Data were collected through online questionnaires. All participants completed a questionnaire, including age, educational level, WeChat activeness, physical exercise, dietary habits, self-reported symptoms and medical history.ResultsA total of 258 women were included in this study, including 96 women with PCOS (PCOS group) and 162 women without PCOS (control group). Among them, 130 women followed our WeChat public account (follower group) and 128 women did not follow the WeChat public account (non-follower group). There were no significant differences in terms of physical activity assessment and dietary assessment between the PCOS and control groups (P>0.05), neither between the followers and non-follower groups (P>0.05). ConclusionsApplication of WeChat public account seems useless in lifestyle management for women with PCOS, however, the conclusion might be limited by the small sample size.

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.

BACKGROUND: Polycystic ovary syndrome (PCOS) is complex hormonal, metabolic and reproductive disorder and is a leading cause of female infertility. Hyperinsulinemia secondary to insulin resistance plays important role in the pathogenesis of PCOS.AIM: To assess the sensitivity of different indices of insulin resistance and their relevance in a clinical setting.MATERIAL AND METHODS: A cross-sectional study of 43 patients with PCOS and 29 noromo ovulatory women as a control group was conducted. Standard clinical, anthropometrical and hormonal testing for hyperandrogenism was conducted, as well as oral glucose tolerance test with determination of basal and stimulated glucose and insulin values.RESULTS: The dynamic I/G index showed the highest sensitivity and specificity, but the static indexes HOMA-IR and QUICKI, although based on only basal glycemic and insulinemic values, showed good sensitivity, 90.38% and 94.01% respectively. HOMA-IR showed significant positive correlation with the stimulated insulin values.CONCLUSIONS: Our results support the use of static indexes in the evaluation of insulin resistance in women with PCOS in a clinical setting, offering a simple assessment of insulin resistance in PCOS, which holds great prognostic and treatment implications.

Abstract Background Altered lifestyle and urbanization have potentially increased the prevalence of polycystic ovary syndrome (PCOS) among the women in India. The aim of the present study was to evaluate the autonomic function and subclinical cognition impairment using evoked potentials in PCOS-affected young adolescents. Methods This was a cross-sectional study, approved by Indian Medical of Council Research as a short-term student project. The study was performed with adolescent girls (age group, 10–18 years) diagnosed as having PCOS, attending the Department of Obstetrics and Gynecology at Sri Manakula Vinayagar Medical College and Hospital, Puducherry. Autonomic function was evaluated using heart rate variability and cognition employing auditory evoked potentials (P300 latency and amplitude) among the control group (n=30) and the PCOS group (n=30). Results Our study reports indicated that autonomic functions were significantly affected among the PCOS group compared to the control group (p=0.03), with sympathetic dominance and decreased vagal tone. P300 latency was prolonged and amplitude was decreased among the PCOS group, but the results were not statistically significant when compared to the control group. Body mass index showed significant correlation with sympathovagal imbalance. Conclusion The study indicates that autonomic functions are significantly altered in the PCOS group. Subclinical cognition impairment is seen among the PCOS group but is not pronounced enough to be proven statistically. This study informs adolescent girls to make early lifestyle changes as soon as possible before any significant clinical impairment occurs.
