OBJECTIVE: Infertility in women has various causes, one of which is ovulation disorders. Polycystic ovary syndrome (PCOS) affecting ovulation is a complex idiopathic disease in which genetic polymorphisms may be involved. This study aimed to investigate the relationship between IL-6 -174 G/C and IL-1A -889 G/A cytokine polymorphisms with polycystic ovary syndrome in a population of Iranian women.
METHODS: In this case-control pilot study, 120 PCOS patients (60 infertile, LPI, and 60 women with recurrent pregnancy abortion, LPA) and 60 controls, CTRLs) participated. After genomic DNA extraction from peripheral blood, we investigated for the polymorphisms rs1800795 of the IL-6 -174 and rs1800587 of the IL-1A-889 using specific primers and PCR-RFLP followed by NlaIII enzyme digestion and PCR-ARMS techniques.
RESULTS: There was a significant difference in the studied groups in terms of clinical characteristics (p-value < 0.05) except for the levels of HDL and LDL. Regarding demographic and clinical characteristics of patients, a significant correlation was observed between C/G and G/G genotypes of rs1800795 and FBS level (p value = 0.002). Also, rs1800587 showed a substantial relationship between CC and CT genotypes with the level of LH in LPI and the level of FBS in the LPAs (p value = 0.04). There was no significant difference between the frequencies of rs1800795 and frequencies of rs1800587 genotypes in the three studied groups (p value > 0.05).The studied variants were in Hardy-Weinberg equilibrium.
CONCLUSIONS: The present work showed that rs1800795 and rs1800587 were not directly associated with PCOS in Iranian patients while the SNPs showed an indirect relationship with some factors affecting the disease. However, using genome-wide association analysis is a proper suggestion to obtain more reliable information about the disease\'s genetic view. To our knowledge, this is the first report that implicates the role of the examined SNPs in an Iranian PCOS population.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that impacts women before reaching menopause. In addition to notable features (irregular ovulation, elevated androgen levels, and the existence of numerous ovarian cysts), individuals with PCOS frequently encounter diverse metabolic, cardiovascular, and psychological conditions. The onset of PCOS is influenced by a combination of factors, and various genetic variations are believed to play a significant role in its progression. The objective of the current study was to explore the link between genetic variations in the candidate genes thyroid-adenoma-associated (THADA) gene and insulin receptor (INSR) and susceptibility to developing PCOS. We conducted an extensive search across various databases, including Google Scholar, PubMed, Science Direct, Scopus, and EMBASE, to compile relevant case-control studies and literature reviews for subsequent statistical analysis. In the present study, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was followed, a guideline for Systematic Reviews and Meta-Analysis. While a previous meta-analysis explored the correlation between INSR rs1799817 and THADA rs13429458 and their association with susceptibility to PCOS, our current study did not integrate any findings from these prior investigations. Our research encompassed articles published between 2017 and 2023, and we employed MetaGenyo software to assess the collected data. Statistical power analysis was performed using G*Power 3.1 software. Odds ratios and their corresponding 95% confidence intervals were calculated for each genetic model. Fifteen studies that met the criteria were analyzed. Out of these, ten studies, involving 1,189 cases and 1,005 controls, examined the INSR rs1799817 gene polymorphism, while five studies, including 783 cases and 553 controls, investigated the THADA rs13429458 gene polymorphism. The meta-analysis results indicated that there was no statistically significant association between the INSR rs1799817 gene polymorphism and the risk of PCOS (p>0.05). In contrast, the THADA rs13429458 gene polymorphism showed a significant association with PCOS risk under the over-dominant model (p<0.05). The present meta-analysis demonstrated a notable association between the THADA rs13429458 gene polymorphism and the likelihood of developing PCOS. Further rigorous studies with expanded sample sizes and diverse ethnic representation will be important to comprehensively evaluate and validate these findings.

Polycystic ovary syndrome (PCOS) is a prevalent metabolic disorder among women of reproductive age, characterized by hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. The pathogenesis of PCOS involves a complex interplay of genetic and environmental factors, including insulin resistance (IR) and resultant hyperinsulinemia. Insulin receptors, primarily in skeletal muscle, liver, and adipose tissue, activate downstream signaling pathways like PI3K-AKT and MAPK-ERK upon binding. These pathways regulate glucose uptake, storage, and lipid metabolism. Genome-wide association studies (GWASs) have identified several candidate genes related to steroidogenesis and insulin signaling. Environmental factors such as endocrine-disrupting chemicals and lifestyle choices also exacerbate PCOS traits. Other than lifestyle modification and surgical intervention, management strategies for PCOS can be achieved by using pharmacological treatments like antiandrogens, metformin, thiazolidinediones, aromatase inhibitor, and ovulation drugs to improve insulin sensitivity and ovulatory function, as well as combined oral contraceptives with or without cyproterone to resume menstrual regularity. Despite the complex pathophysiology and significant economic burden of PCOS, a comprehensive understanding of its molecular and cellular mechanisms is crucial for developing effective public health policies and treatment strategies. Nevertheless, many unknown aspects of PCOS, including detailed mechanisms of actions, along with the safety and effectiveness for the treatment, warrant further investigation.

Background: Currently, the primary strategy for addressing polycystic ovarian syndrome (PCOS) involves lifestyle modifications, with a focus on weight loss. The purpose of this meta-analysis was to assess the impact of weight loss through dietary interventions on inflammatory status and hyperandrogenism in PCOS women. Methods: A comprehensive search was conducted to identify randomised controlled trials (RCTs) and cohort studies assessing the impact of diet-induced weight loss on circulating inflammatory markers (CRP, IL-6, IL-1β, TNF-α), androgens (testosterone, androstenedione), SHBG, and luteinising hormone (LH) in PCOS women. The quality and risk of bias of the included studies were assessed using the Cochrane Collaboration\'s tool for RCTs and the Newcastle-Ottawa Scale for cohort studies. Data were entered into RevMan software v5.9 for the calculation of standard mean difference (SMD) and the 95% confidence interval (95%CI) of circulating inflammatory markers, androgens, and LH between baseline and post-weight loss values. Results: Eleven studies (n = 323) were eligible for the systematic review, of which nine (n = 286) were included in the meta-analysis. Pooled analysis of data revealed a statistically significant decrease in circulating CRP (SMD 0.39, 95%CI 0.22, 0.56; 9 studies, n = 286), IL-6 (SMD 0.37, 95%Cl, 0.12, 0.61; 3 Studies, n = 140), TNF-α (SMD 0.30, 95%Cl, 0.07, 0.53; 4 Studies, n = 162), androstenedione (SMD 0.36, 95%Cl, 0.13, 0.60; 4 studies, n = 147) and LH (SMD 0.30, 95% Cl, 0.09, 0.51; 5 studies, n = 197) after weight loss compared to baseline levels among PCOS women. A meta-analysis of five studies (n = 173) showed a statistically significant increase in circulating SHBG after weight loss compared to baseline levels (SMD -0.43, 95%Cl, -0.65, -0.21). Conclusions: These findings suggest that weight loss induced by dietary interventions seems to improve PCOS-related chronic inflammation and hyperandrogenism. The possible causative relationship between the improvement in inflammation and hyperandrogenism remains to be determined.

BACKGROUND: Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disturbance that affects many women worldwide and is characterized by chronic anovulation, hyperandrogenism, and ovarian dysfunction. Placenta-derived mesenchymal stem cells (PDMSCs) are derived from the placenta and have advantages over other sources of MSCs in terms of availability, safety, and immunomodulation.
METHODS: In this experimental study, twenty female Wistar rats were assigned to four groups (n = 5) including control, sham, PCOS, and PCOS+PDMSCs groups. Then, PCOS was induced in the rats through administering letrozole for 21 days. PDMSCs (1 × 106 cells) were injected through the tail vein. Fourteen days after the cell infusion, evaluation was performed on the number of healthy follicles, corpus luteum, and cystic follicles as well as the levels of testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), fasting blood glucose, fasting insulin, and insulin resistance. Moreover, the serum levels of cholesterol, triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured. Liver function was also determined by the evaluation of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels.
RESULTS: The number of corpus luteum and primordial, primary, secondary, and antral follicles was significantly elevated in the PCOS+PDMSCs group compared to the PCOS group. However, the number of cystic follicles significantly decreased in the PCOS+PDMSCs group. The LH and testosterone levels also decreased significantly, while FSH levels increased significantly in the PCOS+PDMSCs group. The levels of fasting blood glucose, fasting insulin, and insulin resistance notably decreased in the PCOS+PDMSCs group. Moreover, the lipid profile improved in the PCOS+PDMSCs group along with a significant decrease of cholesterol, LDL, and TG and an increase in HDL. The PCOS+PDMSCs group exhibited marked decreases in the AST and ALT levels as well.
CONCLUSIONS: The results of this study suggest that PDMSCs are a potential treatment option for PCOS because they can effectively restore folliculogenesis and correct hormonal imbalances, lipid profiles and liver dysfunction in a rat model of PCOS. However, further research is needed to establish the safety and effectiveness of PDMSCs for treating PCOS.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder characterized by chronic ovulation dysfunction and overproduction of androgens. Women with PCOS are commonly accompanied by insulin resistance (IR), which can impair insulin sensitivity and elevate blood glucose levels. IR promotes ovarian cysts, ovulatory dysfunction, and menstrual irregularities in women patients, leading to the pathogenesis of PCOS. Secreted frizzled-related protein 4 (SFRP4), a secreted glycoprotein, exhibits significantly elevated expression levels in obese individuals with IR and PCOS. Whereas, whether it plays a role in regulating IR-induced PCOS still has yet to be understood. In this study, we respectively established in vitro IR-induced hyperandrogenism in human ovarian granular cells and in vivo IR-induced PCOS models in mice to investigate the action mechanisms of SFRP4 in modulating IR-induced PCOS. Here, we revealed that SFRP4 expression levels in both mRNA and protein were remarkably upregulated in the IR-induced hyperandrogenism with elevated testosterone in the human ovarian granulosa cell line KGN. Under normal conditions without hyperandrogenism, overexpressing SFRP4 triggered the remarkable elevation of testosterone along with the increased nuclear translocation of β-catenin, cell apoptosis and proinflammatory cytokine IL-6. Furthermore, we found that phytopharmaceutical disruption of SFRP4 by genistein ameliorated IR-induced increase in testosterone in ovarian granular cells, and IR-induced PCOS in high-fat diet obese mice. Our study reveals that SFRP4 contributes to IR-induced PCOS by triggering ovarian granulosa cell hyperandrogenism and apoptosis through the nuclear β-catenin/IL-6 signaling axis. Elucidating the role of SFRP4 in PCOS may provide a novel therapeutic strategy for IR-related PCOS therapy.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting approximately 5 to 18% of women of reproductive age and 3 to 11% of teenagers. The diagnostic criteria used in adult patients are not suitable for the diagnosis of adolescent patients, because some of the features may be physiological for puberty, so research is still ongoing to improve the criteria for diagnosing PCOS in teenagers. Polycystic ovary syndrome is associated with hormonal and metabolic changes and may predispose to the occurrence of many other diseases, such as obesity, metabolic syndrome, hypertension, type 2 diabetes and non-alcoholic fatty liver disease (NAFLD). Due to the high prevalence of PCOS and the various health problems it brings, it is necessary to select adolescent girls from the risk group, make an efficient diagnosis, start appropriate treatment, and lead the patient through a lifestyle change as soon as possible. Researchers\' attention is increasingly focused on patients presenting with PCOS already in their teenage years. In our work, we want to look at the latest reports regarding the prevalence, pathophysiology and diagnosis of PCOS in adolescent girls.

UNASSIGNED: Polycystic ovary syndrome (PCOS) is an endocrine metabolic disorder in reproductive-aged women. The study was designed to investigate the metabolic characteristics of different phenotypes in women with PCOS of reproductive age.
UNASSIGNED: A total of 442 women with PCOS were recruited in this cross-sectional study. According to different phenotypes, all women were divided into three groups: the chronic ovulatory dysfunction and hyperandrogenism group (OD-HA group, n = 138), the chronic ovulatory dysfunction and polycystic ovarian morphology group (OD-PCOM group, n = 161), and the hyperandrogenism and polycystic ovarian morphology group (HA-PCOM group, n = 143). The metabolic risk factors and prevalence rates of metabolic disorders among the three groups were compared.
UNASSIGNED: The body mass index (BMI), waist circumference, and waist-to-hip ratio (WHR) of women from the OD-HA group and HA-PCOM group were significantly higher than those of women from the OD-PCOM group (p < 0.05). The serum insulin concentration and homeostasis model assessment of insulin resistance (HOMA IR) at 2 h and 3 h after oral glucose powder in women from the OD-HA group and HA-PCOM group were significantly higher than those from the OD-PCOM group (p < 0.05). The serum total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) in women from the OD-HA group and HA-PCOM group were significantly higher than those in women from the OD-PCOM group (p < 0.05). The prevalence rates of impaired glucose tolerance (IGT), type 2 diabetes mellitus (T2DM), insulin resistance (IR), metabolic syndrome (MS), nonalcoholic fatty liver disease (NAFLD), and dyslipidemia of women with PCOS were 17.9%, 3.6%, 58.4%, 29.4%, 46.6%, and 43.4%, respectively. The prevalence rates of IGT, IR, MS, NAFLD, and dyslipidemia of women in the OD-HA group and HA-PCOM group were significantly higher than those of women in the OD-PCOM group (p < 0.05). T concentration (>1.67 nmol/L) and Ferriman-Gallwey (F-G) score (>3) significantly increased the risk of metabolic disorders in women with PCOS (p < 0.05).
UNASSIGNED: The phenotypes of OD-HA and HA-PCOM in women with PCOS were vulnerable to metabolic disorders compared to OD-PCOM. Thus, the metabolic disorders in women with PCOS especially those with the HA phenotype should be paid more attention in order to reduce long-term complications.

Idiopathic hirsutism (IH) is a common clinical condition with multiple diagnostic and therapeutic uncertainties. There are no clear recommendations for the diagnosis and management of the condition. This practice update was developed to guide the primary care physicians and the specialists in better and more systematic management of IH particularly in the Indian context. Twelve experienced members consisting of eminent endocrinologists, physicians, a dermatologist, a gynaecologist and a psychiatrist were invited by the Integrated Diabetes and Endocrine Academy (IDEA). A literature search was performed using online databases from PubMed, Cochrane Library and Google Scholar. Published articles from peer-reviewed indexed journals, with a preference for meta-analyses and randomized controlled trials, were selected. A meeting took place with all the 12 members individually giving their opinions on predetermined questions of interest. After the initial meeting during IDEACON 2023, two more meetings were held and the practice update was formulated after voting. Practice updates were made on important areas such as the cut-off for modified Ferriman-Gallwey Score for the Indian population, conditions to be excluded before diagnosing IH, when to refer to specialists, investigations in a suspected case of IH and choice of therapies for its management.

UNASSIGNED: Polycystic ovary syndrome (PCOS) is an endocrine gynaecological disorder that affects many women of childbearing age.
UNASSIGNED: To evaluate the efficacy and safety of glucose-like peptide-1 receptor agonists for obese women with PCOS.
UNASSIGNED: We searched the PubMed, Embase, WOS, and Cochrane Libarary databases up to June 2023. Studies were eligible if they were randomised controlled trials (RCTs) comparing GLP-1RAs against any other treatments for patients with PCOS.
UNASSIGNED: Overall, a total of 8 RCTs were included in this review, 7 of the RCTs compared GLP-1RAs with metformin, and 1 RCT compared GLP-1Ras with dapagliflozin. Compared with control group, GLP-1RAs were more effective at improving insulin sensitivity, reducing BMI, and resulting in a smaller waist circumference.
UNASSIGNED: GLP-1RAs may be a good option for obese women with PCOS, especially those with insulin resistance. However, high-quality studies are also needed in the future to assess the efficacy of GLP-1RAs in women with PCOS.
