Abstract
AIMS Alongside its metabolic implications, obesity and associated diabetes impair female reproductive function, causing infertility and polycystic ovarian syndrome (PCOS). Recently, gut hormones and their receptors have been identified in various reproductive organs indicating their potential regulatory effects on reproductive function. This review aims to give an overview of their potential effects. METHODS This review focuses on literature that outlines modifications during obesity, diabetes and related infertility with an emphasis on gut hormones and their therapeutic potential. RESULTS Evidence suggests that bariatric surgery has positive effects on fertility and PCOS where major alterations in metabolism occurs through restoration of gut hormone levels. This is thought to be due to the indirect effect weight loss and regulation of blood glucose has on the hypothalamic-pituitary-ovarian and hypothalamic-pituitary-adrenal axis influencing reproduction. CONCLUSIONS Further research is required to elucidate the cellular mechanisms involved in the direct effects of gut hormone receptor activation on reproductive tissues. Current observations suggest a therapeutic role for gut hormones in infertility/PCOS associated with metabolic pathophysiology.

Relation of resistin gene variants to resistin plasma levels and altered susceptibility to polycystic ovary syndrome: A case control study. Am J Reprod Immunol 2023; 90:e13731. [PMID: 37382171 DOI: 10.1111/aji.13731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 04/19/2023] [Accepted: 05/18/2023] [Indexed: 06/30/2023] Open
Abstract
BACKGROUND A role for resistin in the pathogenesis of polycystic ovarian syndrome (PCOS) and related features were described for various ethnicities. As its expression is partly inherited, a role for RETN polymorphisms in regulating resistin levels and PCOS risk was shown, but with varied results. AIM To investigate the association of rs34124816 (-537A>C), rs1862513 (-420C>G), rs3219175 (-358G>A), rs3745367 (+299G>A), rs3745369 (+1263G>C), and rs1423096 (+4965C>T) RETN SNPs with PCOS. METHODS Study subjects included 583 women with PCOS, and 713 eumenorrheic women serving as controls. Genotyping was done by real-time PCR. RESULTS Higher minor allele frequency (MAF) of rs34124816, rs3219175, and rs3745369, and lower MAF of rs1862513 and rs1423096 were seen in PCOS cases. Reduced PCOS risk was found with rs3745367 minor-allele homozygotes and rs1423096 minor-allele homozygotes, while increased risk was linked with rs3745367 heterozygotes, and with rs3745369 heterozygotes and minor-allele homozygotes. While it did not reach statistical significance, serum resistin levels were elevated in PCOS cases than in control women and major-allele homozygotes of rs34124816 and rs1862513, and in rs1423096 minor-allele-containing carriers. Carriage of rs34124816 correlated positively with age and LH, whereas rs1862513 positively and rs3745367 negatively correlated with fasting glucose. Six-locus (rs34124816-rs1862513-rs3219175-rs3745367-rs3745369-rs1423096) haplotype analysis demonstrated a significant reduction in AGGGGG and a marked increase in AGGGCG haplotypes between cases and controls, thus assigning PCOS protective and susceptible nature to these haplotypes, respectively. CONCLUSIONS This study is the first to document the contribution of rs34124816 and rs1423096 RETN variants to the risk of PCOS. The varied association of RETN gene variants with PCOS suggests an ethnic contribution of RETN association with PCOS.

Abstract
Poly Cystic Ovary Syndrome (PCOS) is mainly characterised by reproductive hormonal imbalance and increased androgen levels, ovulatory dysfunction and polycystic appearing ovaries on ultrasonography. The obesity is common factor to cause PCOS and this adipocytokines play an important role to cause obesity related disorders. Hence, the present study aimed to evaluate the role of adiponectin in women with PCOS compared them with healthy controls. This case control study included total eighty (80) subjects out of this fourty subjects with PCOS and remaining fourty (40) age and body mass index matched healthy controls. The fasting, post parandial blood sugars, glycated haemoglobin, lipid profile and adiponectin levels were measured and data was recorded. There was a significantly elevated levels of total cholesterol, triacylglycerol, very low density lipoprotein, low density lipoprotein (p = 0.0001**) and there were no significant levels of fasting and post parandial blood sugars, glycated haemoglobin levels were observed in women with PCOS than in controls. Additionally, we also observed significantly decreased levels of high density lipoprotein and adiponectin in women with PCOS when compared to healthy controls (p = 0.0001**). The adiponectin shown a positive correlation with age, high density lipoprotein and negative correlation with total cholesterol, triacylglycerol, very low density lipoprotein and low density lipoprotein (p = 0.0001**). The altered adiponectin levels in polycystic ovary syndrome appear to form an important link between obesity and the complications of PCOS.

Treatment with combined resveratrol and myoinositol ameliorates endocrine, metabolic alterations and perceived stress response in women with PCOS: a double-blind randomized clinical trial. Endocrine 2023; 79:208-220. [PMID: 36169918 DOI: 10.1007/s12020-022-03198-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 09/13/2022] [Indexed: 01/13/2023]
Abstract
PURPOSE The present study aimed to assess whether treatment with combined resveratrol and myoinositol is more effective in ameliorating the altered parameters associated with PCOS when compared to the combined metformin and pioglitazone therapy. METHOD One hundred and ten obese, oligo-anovulatory PCOS women, aged 20-35 years were randomly assigned into two treatment arms. Participants in arm-1 (n = 55), received combination of metformin and pioglitazone (500 mg and 15 mg, respectively), twice daily, while those in arm-2 (n = 55) received combination of resveratrol and myoinositol (1000 mg and 1000 mg, respectively) twice daily for 12 weeks. Evaluations performed at baseline were repeated after 3 months of therapy. The endocrine and metabolic derangements were assessed by measuring serum levels of testosterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), adiponectin and insulin using ELISA. Cohen's perceived stress scale (PSS) was employed as a subjective measure of stress. RESULTS Pre-treatment PCOS women in both the arms (arm-1 and arm-2) had remarkably elevated serum testosterone and insulin concentrations, low serum adiponectin and high perceived stress response scores. The treatment reduced the altered endocrine indices in arm-2 (resveratrol and myoinositol) participants, manifested by statistically significant reduction in serum testosterone level (p = 0.001) and notably increased serum adiponectin level (p = 0.001). Interestingly, the hormonal profile, including serum LH and FSH levels also decreased (p < 0.001) along with a marked reduction in the ovarian volume (p = 0.001) in arm-2 participants. There was a significant reduction in weight (<0.001), BMI (p < 0.001) and an improvement in waist-hip ratio (p < 0.001) in arm-2 participants compared to arm-1 group. The PSS scores of the arm-2 subjects improved significantly (p < 0.001) whereas, the Ferrimen-Gallwey score was improved in both the arms (arm-1 and arm-2; p = 0.010 and 0.008 respectively) however, the change was highly significant in arm-2. Interestingly, the menstrual regularity was 81.4% in arm-2 while 18.2% in arm-1. We conclude that the therapeutic intervention with combined resveratrol and myoinositol is more effective in ameliorating altered endocrine, metabolic indices and stress burden and could be of clinical importance in high risk group of obese, oligo-anovulatory married PCOS affected women.

Abstract
A body of studies has examined the circulating concentration of adipokines including apelin, vapin, resistin, and chemerin in polycystic ovary syndrome (PCOS) patients. However, their findings have been inconclusive. Therefore, we systematically reviewed available studies to illuminate the overall circulating concentration of adipokines in PCOS subjects. Cochrane's Library, PubMed, Scopus, and ISI Web of Science databases were searched from the earliest available date up to April 2021 for relevant articles. The quality of each study was assessed by the Newcastle-Ottawa Quality Assessment Scale. The pooled effect size was estimated based on the random effects model, and the standard mean differences (SMD) with a 95% confidence interval (CI) were reported. A total of 88 studies met the inclusion criteria and were included in the current systematic review and meta-analysis. The results of the analysis showed that serum levels of vaspin (SMD 0.69; 95% CI, 0.22 to 1.17; P = 0.004; I2 = 90.6%), chemerin (SMD 1.87; 95% CI, 1.35 to 2.40; P < 0.001; I2 = 94.4%), and resistin (SMD 0.66; 95% CI, 0.41 to 0.91; P < 0.001; I2 = 92.6%) were significantly higher in the PCOS group compared to controls. However, there was no significant difference between the PCOS and control groups in relation to apelin levels (SMD - 0.17; 95% CI, - 1.06 to 0.73; P = 0.714; I2 = 97.8%). We found that serum levels of vaspin, chemerin, and resistin were significantly higher in PCOS subjects compared with controls. It seems that these adipokines can be measured as a useful marker to predict the development of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is the most common gynecological endocrine disease, involving multiple genes, multiple pathways, and complex hormone secretion processes. Hence, the pathogenesis of PCOS cannot be explained by a single factor. Omics analysis includes genomics, transcriptomics, and proteomics, which are fast and effective methods for studying the pathogenesis of diseases. PCOS is primarily characterized by androgen excess, and reproductive and metabolic dysfunctions. The application of omics analysis in the body fluids, blood, cells or tissues of women with PCOS offers the potential for unexpected molecular advantages in explaining new mechanisms of PCOS etiology and pathophysiology, and provides new perspectives for identifying potential biomarkers and developing new therapeutic targets. At present, several omics analyses have been applied to produce complex datasets. In this manuscript, the recent advances in omics research on PCOS are summarized, aiming at an important and parallel review of the newly published research.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a common endocrine-metabolic disorder and the main cause of infertility in women of reproductive age. Affected women suffer from insulin resistance and present with an intense stress response. Treatment with insulin sensitizers alone and in combination is used to ameliorate the signs and symptoms associated with the disease. This study was designed to compare the endocrine and metabolic parameters as well as subjective and objective measures of stress in women with PCOS before and after treatment with acetyl-L-carnitine (ALC) and metformin plus pioglitazone. METHODS A total of 147 women with PCOS were randomly assigned into two groups: the combo group (n = 72) received a combination of metformin, pioglitazone, and ALC (500 mg, 15 mg, and 1500 mg, respectively), twice daily; the Met + Pio group (n = 75) received metformin plus pioglitazone (500 mg, 15 mg, respectively) and placebo (citric acid plus calcium carbonate), twice daily for 12 weeks. Medications were discontinued when pregnancy was confirmed. The Perceived Stress Scale (PSS14) and Profile of Mood States (POMS) were employed as subjective measures of stress. The endocrine and metabolic functions of women with PCOS were assessed by measuring insulin, leutinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, and adiponectin levels in fasting blood samples. Insulin resistance was calculated by Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). RESULTS Women at baseline had significantly elevated circulating concentration of insulin and low level of adiponectin. Treatment decreased insulin in both groups; however, the combo group showed a significant decrease (p = 0.001). Serum adiponectin level was raised significantly after treatment in both groups (p < 0.001). HOMA-IR also decreased in both groups (both p < 0.001). Testosterone, FSH, and LH significantly improved in both groups. LH also decreased in both groups; however, the change was significant only in the combo (metformin plus pioglitazone plus ALC) group (p = 0.013). Interestingly, there was a significant improvement in body circumference (p < 0.001) in the combo group. The PSS scores of the patients improved significantly (p < 0.001) in the combo group. Interestingly, regular menstrual cycles were found (97.2%) in the carnitine group, but in only 12.9% of the other group. CONCLUSION We conclude that addition of ALC therapy is superior to metformin plus pioglitazone in ameliorating insulin resistance, polycystic ovaries, menstrual irregularities, and hypoadiponectinemia in women with PCOS.

Circulating resistin and follistatin levels in obese and non-obese women with polycystic ovary syndrome: A systematic review and meta-analysis. PLoS One 2021; 16:e0246200. [PMID: 33740002 PMCID: PMC7978365 DOI: 10.1371/journal.pone.0246200] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Accepted: 01/15/2021] [Indexed: 12/20/2022] Open
Abstract
This meta-analysis was performed to resolve the inconsistencies regarding resistin and follistatin levels in women with polycystic ovary syndrome (PCOS) by pooling the available evidence. A systematic literature search using PubMed and Scopus was carried out through November 2020 to obtain all pertinent studies. Weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) were calculated to evaluate the strength of the association between the levels of resistin and follistatin with PCOS in the overall and stratified analysis by obesity status. A total of 47 publications, 38 for resistin (2424 cases; 1906 controls) and 9 studies for follistatin (815 cases; 328 controls), were included in the meta-analysis. Resistin levels were significantly higher in PCOS women compared with non-PCOS controls (WMD = 1.96 ng/ml; 95%CI = 1.25–2.67, P≤0.001) as well as in obese PCOS women vs. obese controls, and in non-obese PCOS women compared with non-obese controls, but not in obese PCOS vs. non-obese PCOS patients,. A significantly increased circulating follistatin was found in PCOS patients compared with the controls (WMD = 0.44 ng/ml; 95%CI = 0.30–0.58, P≤0.001) and in non-obese PCOS women compared with non-obese controls and in obese PCOS women vs. obese controls, but, no significant difference in follistatin level was observed in obese PCOS compared with non-obese PCOS women. Significant heterogeneity and publication bias was evident for some analyses. Circulating levels of resistin and follistatin, independent of obesity status, are higher in women with PCOS compared with controls, showing that these adipokines may contribute to the pathology of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a complex multigenic disorder and women with PCOS suffer from several comorbidities. Although, obesity is a known risk factor for PCOS, the incidence of lean women with PCOS is on the rise. A systematic and comparative study on lean and obese PCOS with respect to genes, pathways and comorbidity analysis has not been attempted so far. Analysis of differentially expressed genes (DEGs) across tissue types for lean and obese PCOS revealed that the majority of them were downregulated for lean and obese PCOS. Ovarian and endometrial tissues shared several commonly dysregulated genes, suggesting shared PCOS pathophysiology mechanisms exist across tissues. Several pathways for cellular homeostasis, such as inflammation and immune response, insulin signaling, steroidogenesis, hormonal and metabolic signaling, regulation of gonadotrophic hormone secretion, cell structure and signaling that are known to be affected in PCOS were found to be enriched in our gene expression analysis of lean and obese PCOS. The gene-disease network is denser for obese PCOS with a higher comorbidity score as compared to lean PCOS.

Abstract
Visfatin and resistin appear to interfere with reproduction in the gonads, but their potential action at the hypothalamic-pituitary level is not yet known. The aim of the present study was to investigate the mRNA and protein expression of these adipokines in murine gonadotroph cells and to analyse the effects of different concentrations of recombinant mouse visfatin and resistin (0.01, 0.1, 1 and 10ngmL-1) on LH secretion and signalling pathways in LβT2 cells and/or in primary female mouse pituitary cells. Both visfatin and resistin mRNA and protein were found in vivo in gonadotroph cells. In contrast with resistin, the primary tissue source of visfatin in the mouse was the skeletal muscle, and not adipose tissue. Visfatin and resistin both decreased LH secretion from LβT2 cells after 24h exposure of cells (P<0.03). These results were confirmed for resistin in primary cell culture (P<0.05). Both visfatin (1ngmL-1) and resistin (1ngmL-1) increased AMP-activated protein kinase α phosphorylation in LβT2 cells after 5 or 10min treatment, up to 60min (P<0.04). Extracellular signal-regulated kinase 1/2 phosphorylation was transiently increased only after 5min resistin (1ngmL-1) treatment (P<0.01). In conclusion, visfatin and resistin are expressed in gonadotroph cells and they may affect mouse female fertility by regulating LH secretion at the level of the pituitary.

[PMID: 30055769 DOI: 10.1016/j.nutres.2018.04.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2017] [Revised: 04/03/2018] [Accepted: 04/08/2018] [Indexed: 12/14/2022]
Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women of reproductive age, and recently, chromium was discussed as an adjuvant way to manage it. Herein, a systematic review was conducted which centered on the effects of chromium on ovarian physiology with a focus on body mass index, as well as hormonal and metabolic dysfunctions in women suffering from PCOS. This review was performed using the guidelines from Preferred Reporting Items for Systematic Reviews. Clinical trials investigating chromium in women with PCOS with outcome measures related to metabolic and hormonal status were included. The search was conducted using PubMed, Scopus, and Google Scholar databases for clinical trials in the English language from the inception of the resources until May 2017 with the terms: chromium, chromium picolinate, CrP, polycystic ovary syndrome, PCOS, and sclerocystic ovary syndrome. The search resulted in 89 articles, and after inclusion and exclusion criteria were applied, 6 articles were selected for analysis. Two studies that evaluated the effect of chromium on body weight or body mass index reported no effect. Another study reported the beneficial effect of chromium on weight reduction. It seems that the effect of chromium in the reduction of blood glucose is insignificant, and results are inconsistent in relation to dyslipidemia. With regard to the effects of chromium on concentrations of sex hormones, a longer duration of treatment is needed to produce significant changes. The articles reviewed demonstrated that chromium supplementation has limited effects on weight reduction, glucose control, lipid profile, and hormonal disturbance of women with PCOS; however, more studies are needed due to the clinical changes observed in patients with PCOS after chromium supplementation.

Abstract
Mammalian reproduction is controlled by the hypothalamic-pituitary-gonadal axis. GnRH from the hypothalamus regulates synthesis and secretion of gonadotropins, LH and FSH, which then control steroidogenesis and gametogenesis. In females, serum LH and FSH levels exhibit rhythmic changes throughout the menstrual or estrous cycle that are correlated with pulse frequency of GnRH. Lack of gonadotropins leads to infertility or amenorrhea. Dysfunctions in the tightly controlled ratio due to levels slightly outside the normal range occur in a larger number of women and are correlated with polycystic ovaries and premature ovarian failure. Since the etiology of these disorders is largely unknown, studies in cell and mouse models may provide novel candidates for investigations in human population. Hence, understanding the mechanisms whereby GnRH regulates gonadotropin hormone levels will provide insight into the physiology and pathophysiology of the reproductive system. This review discusses recent advances in our understanding of GnRH regulation of gonadotropin synthesis.

Abstract
Polycystic ovary syndrome (PCOS) is a frequent endocrine disease in women, with a number of metabolic and reproductive consequences. Obesity, insulin resistance (IR) and type 2 diabetes are prominent metabolic characteristics of PCOS and common factors affecting liver function and generating nonalcoholic fatty liver disease (NAFLD). Multiple genes involved in the synthesis of androgens, cytokines and IR, as well as acquired factors, such as endocrine disruptors, could associate the etiopathogenesis of PCOS and NAFLD. Besides the high prevalence of PCOS in general population, NAFLD was shown to be a frequent condition in transition periods, such as adolescence and menopause. Although liver biopsy is considered to be the gold standard for diagnosing liver damage, its routine use in such a prevalent condition as PCOS can be related to a higher rate of complications. Therefore, it is necessary to be able to diagnose NAFLD using simple and reliable surrogate markers. Recently, fatty liver index and NAFLD fatty liver score analyzed in large cohorts of PCOS women have been shown as accurate markers of liver damage in this metabolically vulnerable population. Lifestyle changes are still the mainstay of the management of NAFLD in PCOS, although prospective randomized controlled clinical studies remain a priority in the field. With regard to medications, metformin may be the drug of choice for treating PCOS patients with NAFLD when pharmacologic therapy is considered. Liraglutide use in obese PCOS has shown favorable effects on the predictors of liver fibrosis. In this review, we aim to summarize the influence of the common risk factors and to discuss the diagnostic approaches and management options for NAFLD in patients with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine-metabolic disorder in women of reproductive age. The diagnostic criteria include two out of three features: hyperandrogenism, polycystic ovaries on ultrasound and menstrual irregularities (Rotterdam Criteria 2003). PCOS patients are more vulnerable to develop diabetes, cardiovascular diseases and metabolic syndrome. Insulin resistance (IR) is prevalent in women with PCOS independently of obesity and is critically involved in reproductive and metabolic complications of the syndrome. Several tests have been developed to measure IR, some very reliable but complex like the hyperinsulinemic euglycemic glucose clamp and others less precise but easier and less invasive like HOMA-IR. New markers are needed to reach a more reliable assessment of insulin resistance. To date, several surrogate markers have been proposed in the literature to facilitate and improve the determination of IR. Many new proteins are strongly involved with PCOS physiopathology and IR, such as some adipocytokines (adiponectin, visfatin, vaspin and apelin), copeptin, irisin, PAI-1 and zonulin. Many other proteins have been proposed as potential new markers of IR in PCOS, such as resistin, leptin, RBP4, kisspetin and ghrelin, but their role is still controversial. In this review, we provide a short characterization of these new markers, recently studied as indicators of metabolic state.

Abstract
PURPOSE To investigate the expression of Adaptor protein containing a PH domain, PTB domain and leucine zipper motif 1 (APPL1), insulin receptor (INSR), adiponectin and adiponectin receptors (adipoR1 and R2) and their possible associations in granulosa cells (GCs) of 22 polycystic ovary syndrome (PCOS) women compared to the 22 non-PCOS controls with normal ovulatory function matched for BMI (body mass index). METHODS In this study, 44 infertile women aged 18-40 years undergoing in vitro fertilization (IVF) protocol were recruited. After follicular fluid collection, GCs were isolated and then purified with MACS (Micro Beads conjugated to monoclonal anti-human CD45 antibodies). RNA was extracted from GCs and quantitative real-time PCR (qRT-PCR) was performed to assess APPL1 gene expression. RESULTS Expression of APPL1, insulin receptor and adiponectin system genes was significantly decreased in PCOS group compared to the controls. CONCLUSIONS Reduction of APPL1, insulin receptor and adiponectin system genes in GCs could be involved in the development of PCOS.

Abstract
Objective Ischemia-mediated oxidative stress and inflammation have been reported to be important contributors to the pathogenesis of polycystic ovary syndrome (PCOS). Ischemia-modified albumin (IMA) is a novel marker generated under ischemic and oxidative conditions and may reflect disease activity in distinct disease states. Therefore, we investigated whether the serum IMA levels are affected in infertile PCOS patients. Methods Forty-six patients with infertile PCOS, 30 patients with unexplained infertility, and 31 age- and body mass index (BMI)-matched controls were included in this cross-sectional study. Biochemical parameters, serum IMA levels, and their correlations with serum testosterone and insulin resistance were determined for each subject. Results In patients with infertile PCOS, the serum IMA levels were significantly elevated (p=0.003) compared with unexplained infertility patients and controls. A correlation analysis suggested that the IMA levels only correlated with the serum free testosterone levels in PCOS patients (r=0.43, p=0.028). Conclusion Elevations in the serum IMA levels in infertile PCOS patients may suggest a possible additional role of oxidative stress mechanisms in disease pathophysiology. Moreover, correlation between serum IMA and testosterone levels may influence the quality of oocytes via alterations in the balance of critical follicular fluid factors in the follicular microenvironment.

Abstract
We aimed at investigating whether insulin resistance (IR)/sensitivity are impaired in obese/non-obese polycystic ovary syndrome (PCOS) and obese/non-obese healthy controls. A comprehensive literature search was performed for observational, English language studies. Meta-analysis was performed with the random effects model according to the heterogeneity. Eligible studies, involving 3037 women in four groups of: 1-obese, PCOS; 2-non-obese, PCOS, 3-obese, non-PCOS and 4-Non-obese, non-PCOS were included. Based on the insulin resistance index (HOMA-IR) analysis, the pooled mean (95% Conf. Interval) of HOMA IR in groups 1-4 were 4.38 (3.84, 4.92), 2.68 (2.16, 3.20), 2.44 (2.06, 2.82) and 1.34 (1.06, 1.63), respectively. Meta-analysis showed that group 1 (obese, PCOS patients) statistically have the highest IR and group 4 (non-obese, non-PCOS women) have the highest insulin sensitivity. Group 2 (non-obese, PCOS patients) and group 3 (obese, non-PCOS women) were between this range and they had lower IR than group 1 (obese, PCOS) and lower insulin sensitivity than group 4 (non-obese, non-PCOS). So, there were statistical differences between all groups except between groups 2 and 3. Insulin sensitivity indexes (quickie and ISI), also confirm the IR index (HOMA-IR) results. Based on different IR/sensitivity indexes, we found no evidence of any different effects of BMI ≥ 30 kg/m(2) on IR/sensitivity. In conclusion, PCOS status intensifies the adverse effects of obesity on IR, it has to be appropriately addressed in primary and secondary preventive cares and treatments provided for these women.

Abstract
The objective of this study is to measure serum chemerin levels in women with polycystic ovary syndrome (PCOS) and assess their relationship with clinical, metabolic, and hormonal parameters. One hundred eighteen PCOS women and 114 healthy women were recruited in this study. Their blood pressure, body mass index (BMI), waist circumference and waist-to-hip ratio (WHR), fasting insulin (FIN), fasting plasma glucose (FPG), blood serum sex hormone, and blood lipid were measured. Serum chemerin, leptin, and adiponectin were measured by ELISA. Serum chemerin was significantly higher in the obese PCOS group (47.62 ± 11.27 ng/mL) compared with non-obese PCOS (37.10 ± 9.55 ng/mL) and the obese (33.71 ± 6.17 ng/mL) and non-obese (25.78 ± 6.93 ng/mL) control groups (p < 0.05). Serum chemerin was positively related to BMI, waist circumference, WHR, testosterone (T), FPG, FIN, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), LDL-C/high-density lipoprotein(HDL-C), TC/HDL-C and serum leptin, while negatively related to glucose-to-insulin ratio (G/I), HDL-C, and adiponectin levels. Multiple linear regression analysis revealed HOMA-IR, leptin, and TC were the significant influencing factors of chemerin levels (p < 0.05). Increased serum chemerin in PCOS woman with or without obesity suggested that chemerin may be involved in the development of the pathogenesis of PCOS.

Abstract
Background: This study aimed to find a correlation between increased body mass index (BMI), insulin resistance (IR), hyperandrogenism, and anti-mullerian hormone (AMH) serum levels with the number of follicles retrieved in polycystic ovary syndrome (PCOS) patients. Materials and Methods: The descriptive study was taken on 80 women with average ages of 20-35 years at Alzahra Hospital of Tabriz-Iran who referred for in vitro fertilization. Patients were divided into four groups and serum levels of AMH, testosterone and IR were evaluated at the puncture time. Results: The mean number of follicle retrieved was higher in PCOS (P < 0.05) group than non-PCOS patients. There was a negative significant correlation of follicle number with BMI (r = −0.26, P < 0.05). The ratio of follicle numbers in PCOS/overweight group decreased in comparison to PCOS/normal weight group (−30%, P < 0.05) while the follicle numbers in non-PCOS/overweight patients decreased in comparison with non-PCOS/normal weight (−26%, P > 0.05). There was a significant negative association between BMI with AMH (r = −0.59, P < 0.05), BMI with the follicle numbers (r = −0.2, P < 0.05) and a positive association BMI with -IR (r = 0.3, P < 0.05), but there wasn’t a significant correlation between BMI with testosterone (r = 0.1, P < 0.5). Conclusion: Our finding provides that increasing BMI with direct effect on AMH levels and IR can affect the number of follicles, which are retrieved in these patients.

Abstract
Objective. To review the benefits and harms of N-acetylcysteine (NAC) in women with polycystic ovary syndrome (PCOS). Method. Literature search was conducted using the bibliographic databases, MEDLINE (Ovid), CINAHL, EMBASE, Scopus, PsyInfo, and PROQUEST (from inception to September 2013) for the studies on women with PCOS receiving NAC. Results. Eight studies with a total of 910 women with PCOS were randomized to NAC or other treatments/placebo. There were high risk of selection, performance, and attrition bias in two studies and high risk of reporting bias in four studies. Women with NAC had higher odds of having a live birth, getting pregnant, and ovulation as compared to placebo. However, women with NAC were less likely to have pregnancy or ovulation as compared to metformin. There was no significant difference in rates of the miscarriage, menstrual regulation, acne, hirsutism, and adverse events, or change in body mass index, testosterone, and insulin levels with NAC as compared to placebo. Conclusions. NAC showed significant improvement in pregnancy and ovulation rate as compared to placebo. The findings need further confirmation in well-designed randomized controlled trials to examine clinical outcomes such as live birth rate in longer follow-up periods. Systematic review registration number is CRD42012001902.

Abstract
OBJECTIVE To investigate the effects of cryptotanshinone (CRY), an active component of Chinese medicine, on ovarian androgen production, insulin resistance (IR), and glucose metabolism in mice. DESIGN Animal model and in vitro tissue model. SETTING University-affiliated laboratory. ANIMAL(S) Mice. INTERVENTION(S) Ovarian IR was induced by dexamethasone (DEX) in vivo. Animals were randomized to receive CRY treatment for 3 days or not. Ovulation rates, serum steroid levels, and glucose uptake in ovaries were quantified, and proteins in the phosphatidylinositol 3-hydroxy kinase pathway were measured. In vitro ovarian IR was also induced by DEX for 3 days. Ovarian steroid hormone secretion and glucose uptake were measured, and the hormone-synthesizing enzymes were determined by semiquantitative reverse transcription-polymerase chain reaction. MAIN OUTCOME MEASURE(S) Ovarian glucose uptake, in vivo ovulation rate, serum and culture medium steroid level, and molecular expression of phosphatidylinositol 3-hydroxy kinase and steroidogenic enzymes. RESULT(S) Dexamethasone significantly increased ovulation rates in vivo and increased T and E2 production and decreased ovarian glucose uptake in vivo and in vitro. Cryptotanshinone significantly reduced ovulation rates in vivo and decreased T and estrogen production in vitro. Cryptotanshinone attenuated the inhibition of DEX on AKT2 and suppressed the up-regulation of CYP11 and CYP17 expression by DEX. CONCLUSION(S) Cryptotanshinone reversed DEX-induced androgen excess and ovarian IR in mice through activation of insulin signaling and the regulation of glucose transporters and hormone-synthesizing enzymes. This suggests a potential role for CRY in treating the ovulatory dysfunction associated with PCOS.
