ABSTRACT There has been a surge of interest in recent years in studying the changes of serum melatonin concentrations in disorders that are associated with insulin resistance such as diabetes mellitus type 2 and polycystic ovary syndrome (PCOS). AIM: The present study was designed to investigate the day-time and night-time levels of serum melatonin and the cortisol rhythm in women with PCOS and compare them with those of healthy women. PATIENTS AND METHODS: This is a case-control study which included 30 women with PCOS and 25 healthy women. All hormonal measurements in both the study group and controls were carried out between days 3 and 5 counted from the beginning of the last regular menstrual cycle; they included serum levels of melatonin and cortisol at 03:00 a.m and 08:00 a.m, total testosterone (T), dehydroepiandrosterone sulfate (DHEA-S), luteinizing hormone (LH), follicle stimulating hormone (FSH), and immunoreactive insulin at 08:00 a.m. RESULTS: Women with PCOS were found to have a significantly higher melatonin level at 08:00 a.m. and smaller mean night-day difference in the concentrations of melatonin in comparison with those of healthy women (natural log (Ln) night-day difference 0.60 ± 0.10 pg/ml versus 1.15 ± 0.14, p < 0.002). Melatonin to cortisol ratios at 03:00 a.m. and 08:00 a.m. showed no statistically significant differences between the two groups (Ln melatonin/ cortisol 03:00 a.m., 1.01 ± 0.06 versus 1.05 ± 0.05; Ln melatonin/cortisol at 08:00 a.m., 0.62 ± 0.01 versus 0.56 ± 0.03, p > 0.05). CONCLUSION: The results we obtained about the changes of melatonin in women with PCOS could help in elucidating the complex pathophysiological pattern of this disease.

Abstract Objective The present study aimed to investigate the physical performance of handgrip strength (HGS) in women with polycystic ovary syndrome (PCOS). Methods A case-control study that included 70 women with PCOS and 93 age-matched healthy women aged between 18 and 47 years with body mass index (BMI) between 18 Kg/m2–39.9 Kg/m2. The serum levels of total testosterone, androstenedione, insulin, estradiol, thyroid-stimulating hormone (TSH), prolactin, sex hormone-binding globulin (SHBG), and 17-hydroxyprogesterone (17-OHP) were measured. The free androgen index (FAI) and the homeostatic model assessment of insulin resistance (HOMA-IR) were calculated. The body composition regions of interest (ROIs) were assessed by dual-energy X-ray absorptiometry (DXA), and the handgrip strength (HGS) was evaluated for both the dominant and the non-dominant hands with a manual Sammons Preston (Bolingbrook, IL, US) bulb dynamometer. Results Women with PCOS had high serum levels of total testosterone (p < 0.01), androstenedione (p = 0.03), and insulin (p < 0.01), as well as high FAI (p < 0.01) and HOMA-IR (p = 0.01) scores. Compared with the non-PCOS group, the PCOS group had greater total lean mass in the dominant hand (p < 0.03) and greater HGS in both the dominant and the non-dominant hands (p < 0.01). The HGS was correlated with lean mass (p < 0.01). Conclusion Women with PCOS have greater HGS. This may be associated with age and BMI, and it may be related to lean mass. In addition, the dominance effect on muscle mass may influence the physical performance regarding HGS in women with PCOS.

Neuropeptides coordinate and regulate physiological processes in all animals. Alarin is a 25 amino acid neuropeptide which promotes the secretion of luteinizing hormone (LH). It has been known that serum luteinizing hormone levels are increased in women with polycystic ovary syndrome. Therefore, purpose of this was to examine the association of circulating gonadotropin secretions, and alarin with women with polycystic ovary syndrome, and to compare these findings with those of control subjects in an effort to better understand the pathophysiology of PCOS. 28 participants with a diagnosis of PCOS with normal weight and 28 participants with a diagnosis of PCOS with obese and 28 control group participants were included in this case-control study. Hormone profiles of the participants (alarin, insulin, estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEA-SO4 ), lipid profiles total testosterone, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride, cholesterol) and fasting blood sugar (FBS) values were measured. Results: Serum androgens were elevated in the PCOS. Blood LH was also elevated (P < 0.05) but was higher in PCOS than Control. Patients with PCOS had an increased alarin compared with controls. LH/FSH ratio and Alarin /FSH ratio were greater than 2.1, 2.4, respectively. The blood alarin levels were significantly correlated with the serum LH levels (r=0.492, p=0.002) and the LH/FSH ratios (r=0.450, p<0.001) and Alarin/ FSH ratios. The FSH/LH and alarin /FSH ratio were elevated in the PCOS. Based on these results, the FSH/LH and Alarin /FSH ratio appears to be a useful marker of PCOS.

Objective. The present study was designed to compare serum levels of apelin between lean PCOS women and healthy women with regular menses.Study Design. A total of 30 lean patients with PCOS and 30 healthy subjects were included in this study. Serum apelin levels were compared between groups.Results. Serum apelin levels in lean PCOS patients were not significantly different from the control subjects.Conclusion. Our findings indicate that PCOS itself does not seem to change apelin levels. Further investigation on a large number of subjects will need to be conducted to prove the consistent or variable association in PCOS.

Abstract Objective Polycystic ovary syndrome (PCOS) is a highly heritable disease. Emerging evidence elucidated the elevated prevalence of reproductive abnormalities in first-degree relatives (FDRs) of patients with PCOS. Methods Ten databases were searched in December 2020 (PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, CBM, CNKI, VIP and WanFang and WHO international clinical trials registry platform). This study included cohort, case–control, or cross-sectional studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement was followed. Dichotomous data from each of the eligible studies were combined by Mantel-Haenszel model. Standard mean differences with 95% confidence intervals were assessed. Heterogeneities were assessed using I  2 statistics, and the quality of evidence was evaluated by AHRQ EPC program and GRADE approach. Results Thirty-eight studies were included. The prevalence of PCOS (0.22; 95%CI 0.16 to 0.29), menstrual irregularities (0.28; 95%CI 0.22 to 0.34, P&lt;0.01) and ovary morphological changes were elevated in female PCOS FDRs. Female FDRs also presented with increased levels of luteinizing hormone, total testosterone (SMD, 0.53; 95%CI 0.28 to 0.78, P&lt;0.01), unconjugated testosterone, free androgen index, dehydroepiandrosterone sulfate (DHEAS), and anti-Mullerian hormone levels. Subgroup analyses indicated that some of these changes begun in pubertal girls. Furthermore, fathers of PCOS had higher risk of premature baldness. The DHEAS level was elevated in male FDRs. Conclusions The findings of this analysis suggested that FDRs of patients with PCOS suffered from reproductive endocrinological dysregulations. Thus, more attention should be focused on this population. (PROSPERO–CRD42020183243)

Polycystic ovary syndrome (PCOS) is a mainly common endocrine disorder. Hyperandrogenism is the major standard in the diagnosisof PCOS development.Eighty women diagnosed with PCOS and twenty healthy women(aged 20-40 years)were enrolled in this study which was conducted at the infertility clinic of Kamal AL-Samaraay Hospital/ Baghdad. The diagnosis of PCOS was made according to the Rotterdam criteria. Body mass index (BMI, Kg/m2)was calculated by a specific formula. History of menstrual irregularity, hirsutism, acne, and alopecia was taken. Hormone levels in serum, namely luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone were measured in all patients and control subjects.There was a statistically significant difference (P <0.05) in the BMI between the PCOS and control women.Also, the prevalence of overweight and obesity was much higher in PCOS women than in their matching control. The serum levels of LH, FSH, and testosterone were significantly different (P <0.05) in PCOS as compared to healthy women. Clinical hyperandrogenism (hirsutism and alopecia) were present in most of PCOS women, while acne wasa less useful clinical sign of hyperandrogenism.Inaddition, the prevalence of hirsutism and alopecia was  increased in obese  when compared with  overweight and lean PCOS women.

Background:Hirsutism is a distressing medical problem for women. Most of hirsutism in women is associated with excess androgen, and most cases have PCOS as an underlying cause.Which androgen to be used to evaluate clinical or biochemical hyperandrogenism in women with PCOS is still debated.There are a small number of studies that evaluated androgens in women with PCOS having hirsutism with conflicting results. The Objective of this study was to determine which androgen predict hirsutism in women with polycystic ovary syndrome (PCOS). Patients and Methods:A case-control study was done in Faiha Specialized Diabetes, Endocrine, and Metabolism Center (FDEMC), Basrah, Iraq. A total of 130 women with PCOS (based on Rotterdam criteria) and 70 healthy controls of comparable age (16-40 years) were investigated for androgens (total testosterone, free testosterone, DHEA-S) using Electrochemiluminescence technology assay; excess hair was examined according to the modified Ferriman-Gallwey (mFG) score and a cut-off value of 8 defined hirsutism. Results: In the three groups of women, the first (n=100) included PCOS with hirsutism, the second (n=30) PCOS without hirsutism, and the third (n=70) women without PCOS or hirsutism as healthy control, hirsutism was seen in about 77 % of PCOS women mostly of moderate severity; High TT, FT, DHEA-S, and overall androgens were seen in 69%, 76%, 37%, and 99% respectively of our PCOS women with hirsutism. No correlation was found between TT, FT, and DHEA-S and the mFG score. Conclusions: This study provides evidence that presence of hirsutism in women with PCOS was associated with a higher level of biochemical hyperandrogenism than seen in PCOS without hirsutism; however, there was no correlation between the studied androgens and mFG score.

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

Background: Tumor Necrosis Factor Alpha (TNF-α) gene, as an inflammatory factor, plays an important role in reproductive physiology, especially in women with Polycystic Ovary Syndrome (PCOS). Objective: This study aims to investigate the relationship between the -1031 T/C polymorphism of TNF-α gene and biochemical factors in women with PCOS. Methods: In this case-control study, participants were 106 women with PCOS and 114 healthy women referred to Kosar Hospital in Qazvin, Iran. The TNF-α gene’s polymorphism was determined using Polymerase Chain Reaction (PCR) technique and PCR-Restriction Fragment Length Polymorphism (PCR-RFLP) method. Biochemical factors of serum levels were also measured in two groups. Logistic regression analysis examined the relationship between the frequency of alleles in different states and the risk of PCOS. Findings: There were statistically significant difference in the mean levels of total cholesterol, triglycerides, testosterone, two-hour blood glucose and body mass index between the groups, whose values were higher in women with PCOS compared to healthy women (P<0.001). In women with PCOS, the mean serum levels of triglyceride and high-density lipoprotein were significantly different between the three TT, CC, TC genotypes of TNF-α gene polymorphism (P<0.05). The results of regression analysis showed that the TT genotype had significant association with the risk of PCOS (OR=2.43, P=0.006, 95%CI: 1.28-2.62). Conclusion: It seems that there is a relationship between the -1301 (T/C) polymorphism of TNF-α gene and the risk of PCOS in women.

Abstract Context: The hormonal and anthropometric profile of premenopausal women with polycystic ovary syndrome (PCOS) is well described, but there is a lack of data concerning changes in these variables into the postmenopausal period. Objective: Our objective was to examine whether PCOS women differ from normal women regarding levels of reproductive hormones, anthropometry, and presence of hirsutism/climacteric symptoms also after menopause. Design and Setting: In this prospective study, women with PCOS (61–79 yr) and age-matched controls, examined in 1987, were reinvestigated at a university hospital. Participants: Twenty-five PCOS patients (Rotterdam criteria) and 68 controls (randomly allocated from the Gothenburg WHO MONICA study) participated. Interventions: Reexamination and hormonal measurements were done 21 yr after previous visit. Main Outcome Measures: FSH, LH, TSH, thyroid peroxidase antibodies, prolactin, estrone, estradiol, SHBG, androstenedione, total testosterone, dehydroepiandrosterone sulfate, free androgen index, and anthropometry were determined. Presence of climacteric symptoms, hirsutism, and menopausal age were recorded. Results: PCOS women had higher free androgen index (P = 0.001) but lower FSH (P &lt; 0.001) and SHBG (P &lt; 0.01) than controls. Menopausal age, body weight, body mass index, waist to hip ratio, LH, prolactin, androstenedione, dehydroepiandrosterone sulfate, total testosterone, estradiol, and estrone were similar in PCOS and controls. Women with PCOS reported hirsutism more frequently (P &lt; 0.001) but had fewer climacteric symptoms (P &lt; 0.05) and hypothyroidism than controls (P &lt; 0.05). Conclusions: PCOS women differ from controls with regard to levels of certain reproductive hormones also after menopause, but the established premenopausal increase in waist to hip ratio in PCOS patients disappeared after menopause, mainly due to weight gain among controls. A novel finding was the lower prevalence of hypothyroidism in PCOS women.

Exercise can reduce androgen and insulin levels in polycystic ovary syndrome (PCOS) patients. Finasteride is also presumed to improve the developing follicle environment. Therefore, the aim of this study was to observe the effects of the combination of exercise and finasteride therapy on hormone levels and ovarian morphology in rats with polycystic ovary syndrome. Forty female rats were randomly divided into five groups (n=8 each group): the PCOS sedentary group (P-Sed), PCOS exercise group (P-Ex), PCOS finasteride and sedentary group (P-FSed), and PCOS finasteride and exercise group (P-FEx), and healthy, age-matched rats were used as controls (CO). The results indicated that the levels of FINS in the P-FEx group were significantly lower than those in the P-Sed and P-FSed groups, while the ratio of fasting blood glucose (FBG)/fasting serum levels of insulin (FINS) in the P-FEx group was significantly higher than that in the P-Sed and P-FSed groups. Compared to the P-FEx group, serum levels of TT (total testosterone) in the P-Sed and P-FSed groups were significantly increased. The thickness of the follicular membrane and the number of atresia follicles in the P-FEx and CO groups were significantly lower than those in the P-Sed group, but there was no significant difference between the P-Ex and P-Sed groups. These results show that the combined usage of exercise and finasteride does not alter the effects of exercise on increasing insulin sensitivity and reducing androgen levels. There is also a synergistic effect of exercise and finasteride on the morphology of the ovary, including a reduced number of atresia follicles and thickness of the follicular membrane.
