Endoplasmic reticulum stress-mediated ferroptosis in granulosa cells contributes to follicular dysfunction of polycystic ovary syndrome driven by hyperandrogenism. Reprod Biomed Online 2024; 49:104078. [PMID: 39024925 DOI: 10.1016/j.rbmo.2024.104078] [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: 01/11/2024] [Revised: 03/28/2024] [Accepted: 04/23/2024] [Indexed: 07/20/2024]
Abstract
RESEARCH QUESTION Does hyperandrogenaemia affect the function of ovarian granulosa cells by activating ferroptosis, and could this process be regulated by endoplasmic reticulum stress? DESIGN Levels of ferroptosis and endoplasmic reticulum stress in granulosa cells were detected in women with and without polycystic ovary syndrome (PCOS) undergoing IVF. Ferroptosis and endoplasmic reticulum stress levels of ovarian tissue and follicle development were detected in control mice and PCOS-like mice models, induced by dehydroepiandrosterone. An in-vitro PCOS model of KGN cells was constructed with testosterone and ferroptosis inhibitor Fer-1. Endoplasmic reticulum stress inhibitor, tauroursodeoxycholate (TUDCA), determined the potential mechanism associated with excessive induction of ferroptosis in granulosa cells related to PCOS, and levels of ferroptosis and endoplasmic reticulum stress were detected. RESULTS Activation of ferroptosis and endoplasmic reticulum stress occurred in granulosa cells of women with PCOS and the varies of PCOS-like mice. The findings in KGN cells demonstrated that testosterone treatment results in elevation of oxidative stress levels, particularly lipid peroxidation, and intracellular iron accumulation in granulosa cells. The expression of genes and proteins associated with factors related to ferroptosis, mitochondrial membrane potential and ultrastructure showed that testosterone activated ferroptosis, whereas Fer-1 reversed these alterations. During in-vitro experiments, activation of endoplasmic reticulum stress induced by testosterone treatment was detected in granulosa cells. In granulosa cells, TUDCA, an inhibitor of endoplasmic reticulum stress, significantly mitigated testosterone-induced ferroptosis. CONCLUSIONS Ferroptosis plays a part in reproductive injury mediated by hyperandrogens associated with PCOS, and may be regulated by endoplasmic reticulum stress.

Healthcare and research priorities for women with polycystic ovary syndrome in the UK National Health Service: A modified Delphi method. Clin Endocrinol (Oxf) 2024; 100:459-465. [PMID: 38420872 DOI: 10.1111/cen.15038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 02/16/2024] [Indexed: 03/02/2024]
Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a chronic lifelong condition affecting up to 20% of women worldwide. There is limited input from affected women to guide the provision of healthcare services and future research needs. Our objective was to scope the healthcare and research priorities of women with PCOS in the United Kingdom. DESIGN A three-staged modified Delphi method, consisting of two questionnaires and a consensus meeting involving lay representatives and healthcare professionals. PATIENTS AND MEASUREMENTS Lay patient representatives of women with PCOS. Participants were asked to identify and rank healthcare and research priorities for their importance. RESULTS Six hundred and twenty-four lay participants took part in our Delphi method. Over 98% were diagnosed with PCOS (614/624, 98.4%). More than half experienced difficulties to receive a PCOS diagnosis (375/624, 60%), and the majority found it difficult to access specialised PCOS health services in the NHS (594/624, 95%). The top two healthcare priorities included better education for health professionals on the diagnosis and management of PCOS (238/273, 87.1%) and the need to set up specialist PCOS services (234/273, 85.7%). The top two research priorities focused on identifying better treatments for irregular periods (233/273, 85.3%) followed by better tests for early PCOS diagnosis (230/273, 84.2%). CONCLUSIONS We identified 13 healthcare and 14 research priorities that reflect the current health needs of women with PCOS in the United Kingdom. Adopting these priorities in future healthcare and research planning will help to optimise the health of women with PCOS and increase patient satisfaction.

J Endocrinol Invest 2024; 47:1129-1137. [PMID: 37930586 DOI: 10.1007/s40618-023-02230-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 10/19/2023] [Indexed: 11/07/2023]
Abstract
PURPOSE Cardiometabolic risk factors are common in women with polycystic ovary syndrome (PCOS) during reproductive years. The aim of this study was to determine the impact of aging on cardiometabolic risk of the syndrome by examining women who had previously been diagnosed to have PCOS or to be healthy in an unselected population in 2009. PARTICIPANTS Forty-one women with PCOS who were diagnosed and phenotyped according to the Rotterdam criteria and 43 age- and body mass index (BMI)-matched healthy women from the same unselected cohort. METHODS All participants were evaluated by structured interview, physical examination, anthropometric, hormonal and biochemical measurements. Additionally, body composition analyses and echocardiographic assessments of 30 women with PCOS and 30 control women were conducted at 13 years of follow-up. RESULTS There was no difference between the patient and the control groups in terms of anthropometric and body composition measures and metabolic parameters. Echocardiographic assessment showed similar systolic functions, strain measurements and epicardial fat measurements between the groups. PCOS patients still had higher levels of total testosterone, free androgen index (FAI) and dehydroepiandrosterone sulfate (DHEAS) levels compared to controls. Epicardial fat thickness showed positive correlations with BMI, total and truncal body fat, homeostatic model assessment for insulin resistance (HOMA-IR) and free androgen index (FAI). CONCLUSIONS Aging women with PCOS in the population have higher androgen levels and similar cardiometabolic risk profile compared to age- and BMI-matched healthy women. Epicardial fat thickness, a marker of cardiometabolic risk, appear to be associated with hyperandrogenism. Further research is needed on larger community-based cohorts where older patients are assessed with a longer follow-up.

Abstract
Hyperandrogenemia and persistent chronic inflammation, two main striking features of polycystic ovary syndrome (PCOS), have been proven involved in follicular dysgenesis in PCOS. However, the association between hyperandrogenism and inflammation activation in PCOS is not fully understood. Excess testosterone(T) induces inflammation and pyroptosis activation in a mouse model of PCOS, leading to ovarian dysfunction and fibrosis. Excessive endoplasmic reticulum (ER) stress is present in ovarian granulosa cells (GCs), testosterone-induced PCOS mouse and cellular models. This study found higher levels of interleukin (IL)-1β, IL-8, IL-17, and IL-18 in the follicular fluid of PCOS patients with hyperandrogenemia undergoing IVF treatment. In addition, pyroptosis in GCs was demonstrated, which was significantly elevated in PCOS patients. To clarify the association of hyperandrogenism, inflammation, and pyroptosis activation in PCOS, dehydroepiandrosterone(DHEA)-treated mouse PCOS model and T-treated KGN cell line were explored for PCOS mechanism. Markers of inflammatory activation and pyroptosis were significantly increased after DHEA treatment in mice and T treatment in KGN cells. In addition, ER stress sensor proteins were increased simultaneously. However, suppression of inflammation by genipin(GP) led to decreased pyroptosis in KGN cells but no variation in ER stress sensor proteins. In contrast, when treated with tauroursodeoxycholic acid(TUDCA) to attenuate ER stress, the markers of inflammatory factors were significantly reduced, accompanied by a reduction in pyroptosis. Our results suggest that persistent hyperandrogenemia of PCOS promotes local inflammatory activation of the ovary, and the imbalanced inflammatory microenvironment leads to pyroptosis of GCs, which is mediated by ER stress activation.

Abstract
Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy in women of reproductive age. The metabolic dysfunction associated with PCOS increases the probability of developing type 2 diabetes (T2D), endometrial cancer, and cardiovascular disease. Research has shown that the metabolic features of PCOS may be improved by weight loss following treatment with glucagon-like peptide-1 receptor (GLP-1R) agonists. Tirzepatide is a dual GLP-GIP (gastric inhibitory polypeptide) receptor agonist that shares a very similar mechanism of action with GLP-1R agonists, and it is hypothesized that it may be a potential contender in the treatment of PCOS. The success of GLP-1R agonists is usually hindered by their adverse gastrointestinal effects, leading to reduced compliance. The mechanism of action of Tirzepatide partly addresses this issue, as its dual receptor affinity may reduce the intensity of gastrointestinal symptoms. Tirzepatide has been licensed for the treatment of type 2 diabetes and given the metabolic issues and obesity that accompanies PCOS, it may be of value in its management for those PCOS patients who are obese with metabolic syndrome, although it may not benefit those who are of normal weight. This study reviews the current therapies for the treatment of PCOS and evaluates the potential use of Tirzepatide to address the symptoms of PCOS, including reproductive dysfunction, obesity, and insulin resistance.

Comparative Evaluation of Aldose Reductase Inhibition in Polycystic Ovarian Syndrome-Induced Rats. Reprod Sci 2023; 30:622-632.

Abstract
Polycystic ovary syndrome (PCOS) represents a spectrum of disorders, associated with hyperandrogenism, oligoanovulation, and polycystic ovaries. Aldose reductase (AR), a rate-limiting enzyme of polyol pathway, is responsible for maintenance of intracellular osmotic balance, facilitation of oocyte development, and organization of the granulosa cells in the ovary. Cyclic changes in the aldose reductase level were found during the 4-5 days estrus cycle in rat, which is regulated by gonadotropin-releasing hormone (GnRH). Irregular GnRH secretion in PCOS patients may lead to altered aldose reductase expression and ovarian dysfunction. Treatment with a novel AR inhibitor, fidarestat, has been reported to improve erythrocyte sorbitol content in diabetic patients. Hence, the potential role AR in pathogenesis of PCOS was investigated by inhibiting AR with fidarestat in PCOS-induced rats. Pre-pubertal female Sprague-Dawley rats were divided into five groups. PCOS is induced either by administering letrozole or by feeding high-fat diet for 90 days. After induction of PCOS, fidarestat treatment was given for 28 days and various parameters were measured. In PCOS-induced rats, parameters like food intake, body weight, insulin, OGTT, triglycerides, cholesterol, prolonged diestrus phase, ovary weight, and immunohistological localization AR were found to be significantly altered. Fidarestat treatment significantly improved ovary weight, ovarian aldose reductase localization in PCOS-induced rats. Improvement in all these parameters suggest involvement of aldose reductase in the pathogenesis of PCOS.

Abstract
BACKGROUND AND OBJECTIVE PCOS is a common metabolic disorder in women of reproductive age, which pathogenesis is very complex. The role of ferroptosis in PCOS is a novel finding, and the mechanistic studies are not clear. Metformin is a commonly used drug of PCOS but few studies on whether metformin can improve the follicle development and ovarian function in PCOS. We aims to use PCOS mouse model to study the effect of metformin on PCOS based on the ovarian function and explored the regulation of metformin in PCOS mice by intervening in ferroptosis pathway. MATERIALS AND METHODS C57 BL/6J female mice aged 4-5 weeks were purchased and gavaged with letrozole (1 mg/kg/day) combined with high-fat diet for 21days to establish PCOS model, and control group was set up. After modeling, the mice were divided into PCOS model group and metformin treatment group (Met) (n=6).The Met group were gavaged metformin (200 mg/kg/day) for 28 days. The body weight, estrous cycle, glucose tolerance test (OGTT)and insulin resistance test (ITT) were monitored. Then, The mice were euthanized to collect serum and ovaries. Elisa was used to detect changes in related serum hormones (E2, LH, FSH, TP). Ovaries used for molecular biology experiments to detect changes in GPX4, SIRT3, AMPK/p-AMPK, and mTOR/p-mTOR by Western blot and qPCR. RESULTS Compared with the model group mice, body weight was significantly reduced, and their estrous cycle was restored in Met group. The results of OGTT and ITT showed an improvment of glucose tolerance and insulin resistance. Morphological results showed that after metformin treatment, polycystic lesions in ovaries were reduced, the ovarian function was restored, and the expressions of SIRT3 and GPX4 were elevated. WB results demonstrated that the expressions of p-mTOR and p-AMPK in ovaries were significantly reduced in Model group, but reversed in MET group. CONCLUSION Our study confirmed metformin could not only improve body weight and metabolism disorders, but also improve ovarian dysfunction in PCOS mice.In addition, we explored metformin could regulate ferroptosis to improve PCOS via the SIRT3/AMPK/mTOR pathway. Our study complements the mechanisms by which metformin improves PCOS.

Abstract
Polycystic ovary syndrome is a low-grade inflammatory state with increased serum levels of TNF-α. The present study has compared the inflammatory responses to breast cancer cell lines in women with PCOS with healthy women. Peripheral blood mononuclear cells (PBMCs) isolated from 50 women with PCOS and 50 healthy controls were cultured in the trans-well co-culture system. These cells were stimulated with two distinct breast cancer cell lines. The proliferation of PBMCs, CD3+CD8+T cell percentages, and tumor necrosis factor-alpha (TNF-α) concentration were evaluated after 48 and 72 hours of incubation. TNF-α concentration and the proliferation rate of PBMCs after 48 hours of incubation significantly increased in the PCOS group. However, after 72 hours, TNF-α secretion significantly decreased in the PCOS group. The ability of PBMCs to produce TNF-α decreased gradually in women with PCOS. When the effects of low-grade inflammation and endocrine conditions on the cells decrease, the inability of PBMCs to create an inflammatory response will be altered.

Abstract
Polycystic ovary syndrome (PCOS) is the most common heterogeneous endocrine disorder among women of reproductive age. The pathogenesis of PCOS remains elusive; however, there is evidence suggesting the potential contribution of genetic interactions or predispositions combined with environmental factors. Among these, endocrine disrupting chemicals (EDCs) have been proposed to potentially contribute to the etiology of PCOS. Granulosa and theca cells are known to cooperate to maintain ovarian function, and any disturbance can lead to endocrine disorders, such as PCOS. This article provides a review of the recent knowledge on PCOS pathophysiology, the role of granulosa and theca cells in PCOS pathogenesis, and the evidence linking exposure to EDCs with reproductive disorders such as PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is a common cause of female infertility, affecting 5-10% of women of reproductive age. Many studies have reported improvement in insulin resistance and thereby intracellular glucose uptake after myo-inositol treatment in PCOS patients, but these studies have a small sample size, varying methodology, and outcome analysis. Therefore, we designed a present meta-analysis of randomized controlled trials to explore the effect of myo-inositol supplementation on anthropometric, metabolic, and endocrine outcomes in PCOS patients. Randomized controlled trials assessing the effectiveness of myo-inositol were identified in electronic databases like PubMed, Cochrane, Embase, MEDLINE, CINAHL, and AMED. Listed references and citations of related articles were also screened manually to identify additional studies. Research papers for which full-text copies were not available on scientific databases were procured from respective authors. Thereafter, data were extracted from included studies and analyzed using RevMan 5.3 of the Cochrane Collaboration. A total of 17 randomized controlled trials with 1083 PCOS patients were included in this meta-analysis. Among the 17 trials, 7 trials compared myo-inositol with folic acid, 8 trials compared myo-inositol with metformin, and 2 trials compared myo-inositol with oral contraceptives. No significant improvement in body mass index, waist-to-hip ratio, fasting insulin, fasting glucose, HOMA, LH, FSH, estradiol, sex hormone-binding globulin, dehydroepiandrosterone, and total testosterone levels were observed after myo-inositol treatment in PCOS patients except androstenedione and prolactin levels. Clinically significant improvement was not observed in anthropometric, metabolic, and endocrine outcomes after myo-inositol treatment in PCOS patients. However, heterogeneity between studies was high.

Abstract
Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine and metabolic disorder, causes irregular menstrual cycles, dyslipidemia, excessive body weight, oxidative stress, hyperandrogenism, and infertility. This study focused on the impact of Cyperus esculentus (CES) on letrozole-induced PCOS in female Sprague-Dawley rats. Twenty (20) normal rats and twenty (20) PCOS rats (150–200 g, 8 weeks old) were randomly divided into four groups of ten ( n = 10) rats each. Group A served as normal control group received 2 mL of normal saline, group B treated with 500 mg/kg body weight of CES , group C PCOS control group received 2 mL of normal saline, and group D PCOS rats post-treated with 500 mg/kg body weight of CES daily through gastric gavage for 30 days. Estrus cyclicity, body and ovaries weights, biochemical and histological parameters were measured. Observed irregular estrus cyclicity and multiple cysts in PCOS rats, increase glycemia, ovarian weight, triglycerides, total cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, malondialdehyde, luteinizing hormone (LH), testosterone, and decrease high-density lipoprotein cholesterol, estradiol, progesterone, catalase, reduced glutathione (GSH), and superoxide dismutase levels, compared with control. The intervention of CES ameliorated and restored the estrus cyclicity reproductive hormone, biochemical, and structural alterations. Moreover, CES significantly decreased cystic follicles, LH, and testosterone levels, but increased estradiol concentration. This plant may be beneficial in the management and treatment of PCOS-related reproductive and metabolic disorders.

Abstract
Polycystic ovary syndrome (PCOS) is a considered one of the most common female disorders associated with reproductive, metabolic, and psychological problems. The etiology of PCOS is still not yet disclosed; however, evidence for a genetic basis has been reported. In this study, we investigate the associations between superoxide dismutase 2 (<i>SOD2</i>) (rs4880) and paraoxonase 1 (<i>PON1</i>) (rs705379) polymorphisms in PCOS in Saudi women. The study included 99 females with PCOS and 98 healthy women as a control. Single nucleotide polymorphisms (SNPs) of promoter regions were determined using TaqMan genotyping assays. Regarding the polymorphism at <i>SOD2</i> (rs4880), the CC, CT, and TT genotypes were present at rates of 32, 61, and 7% in PCOS patients, and 47, 43, and 10% in controls, respectively. The frequency of the CT genotype in PCOS patients (0.61) was significantly higher than in controls (0.43) (OR = 2.05, CI: 1.16–3.61; <i>p</i> = 0.015). The wild homozygous genotype (CC) with the phenotype alanine appears to confer protection against the disease compared to molecules sharing at least one valine (genotypes, CT + TT). Regarding the polymorphism at <i>PON1</i> (rs705379), the rates of CC, CT, and TT genotypes were 34, 50, and 16% in PCOS patients and 33, 63, and 2% in controls, respectively. The rate of the TT genotype in PCOS patients was significantly higher than that in controls (<i>p</i> = 0.0058). <i>SOD2</i> and <i>PON1</i> polymorphisms may be genetic factors that affect the occurrence of PCOS in Saudi females.

Abstract
Maternal perturbations or sub-optimal conditions during fetal development can predispose the offspring to diseases in adult life. Animal and human studies show that prenatal androgen excess may be an underlying cause of polycystic ovary syndrome (PCOS) later in life. In women, PCOS is a common fertility disorder with comorbid metabolic dysfunction. Here, using a sheep model of PCOS phenotype, we elucidate the epigenetic changes induced by prenatal (30-90 day) testosterone (T) treatment and its effect on gene expression in fetal day 90 (D90) and adult year 2 (Y2) ovaries. RNA-seq study shows 65 and 99 differentially regulated genes in prenatal T-treated fetal and adult ovaries, respectively. Interestingly, there were no differences in gene inducing histone marks H3K27ac, H3K9ac, and H3K4me3 or in gene silencing marks, H3K27me3 and H3K9me3 in the fetal D90 ovaries of control and excess T-exposed fetuses. In contrast, except for H3K4me3 and H3K27me3, all the other histone marks were upregulated in the prenatal T-treated adult Y2 ovary. Chromatin immunoprecipitation (ChIP) studies in adult Y2 ovaries established a direct relationship between the epigenetic modifications with the upregulated and downregulated genes obtained from RNA-seq. Results show increased gene inducing marks, H3K27ac and H3K9ac, on the promoter region of upregulated genes while gene silencing mark, H3K9me3, was also significantly increased on the downregulated genes. This study provides a mechanistic insight into prenatal T-induced developmental programming and its effect on ovarian gene expression that may contribute to reproductive dysfunction and development of PCOS in adult life.

Abstract
Polycystic ovarian syndrome (PCOS) is a combination of various symptoms like anovulation, hirsutism, chronic amenorrhea, infertility, obesity and polycystic ovaries. It affects over 7 million women worldwide. The current strategy to treat this disorder is based on the use of drugs that provide symptomatic relief. Most of these, however, exhibit numerous side effects and are not able to ameliorate all the signs and symptoms of PCOS. As dysbiosis is considered as one of the prime underlying causes of PCOS, restoration of eubiosis was considered as a plausible way to treat it. Bacteriotherpeutics like probiotics, synbiotics and even fecal microbiota transplant (FMT) have shown considerable effectiveness in PCOS. Of these baceteriotherapeutic options, FMT is considered to be the most holistic as it encompasses the bacteriome, virome, fungome, archaeome and even parasitome while both probiotics as well as synbiotics mainly comprise bacteria. Repeated FMT, however, is not a pragmatic option because of its inconvenience, lack of standardization, involved risk and scepticism amongst patients and physicians. If the eubiosis ushered by FMT is sustained for a long time, the repeated administrations of FMT can be avoided and maintenance therapy with any agent that can maintain the eubiotic condition can be adopted. Role of curcumin on gut microbiota is widely known. It is largely attributed to the ability of certain microbes to consume polyphenols as substrates and its positive effect on bacterial consumption of nutrients such as sugars. Based on various mechanisms and studies, a new hypothesis is being proposed wherein FMT and curcumin combination is predicted to be an effective and sustained treatment of PCOS with much lower rates of remission.

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.

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
Due to the endocrine disrupting effects of bisphenol A (BPA) several governmental authorities have banned its use and the manufacturers had to find alternative substances with similar chemical properties. This led to the increase in the use of so-called BPA analogues, which however also turn out to possess mild estrogenic and ani-androgenic properties and thus, may cause fertility problems and sex-hormone dependent endocrinopathies. The aim of this study was to evaluate the potential association between the exposure to BPA and its two analogues: BPS and BPF, with the diagnosis of the polycystic ovary syndrome (PCOS), which remains the most common female endocrinopathy. Serum concentrations of BPA, BPS and BPF were measured using high performance liquid chromatography method with tandem mass spectrometry (HPLC-MS/MS) among 199 women with PCOS and 158 control subjects. In women with PCOS serum BPS concentrations were significantly higher compared to the control subjects (geometric mean [95% CI]: 0.14 ng/mL [0.10; 1.17] vs. 0.08 ng/mL [0.06; 0.09], P = 0.023). Serum BPA and BPF concentrations did not differ between the studied groups. There was however a negative correlation between serum BPA and HOMA-IR (r = - 0.233, P = 0.001) and TST (r = - 0.203, P = 0.006) in women with PCOS. No correlations were found between the serum BPs and other metabolic parameters such as serum lipids, insulin, DHEA-S, androstenedione and FAI. When studying the association between serum BPA analogues and PCOS it turned out that women whose serum BPS concentrations were in the first tertile were more likely to be diagnosed with this endocrinopathy (OR [95% CI]: 1.21 [1.04; 3.46], P = 0.017). This association was also statistically significant when adjusted for age, education, BMI, smoking, income, and alcohol consumption (adjusted OR [95% CI]: 1.12 [1.03; 3.71], P = 0.029). These results point to the potential association between the exposure to BPS and the diagnosis of PCOS. The role of BPA is not clear and warrants further studies.

Abstract
PURPOSE This review aims to summarize the key findings of several miRNAs and their roles in polycystic ovary syndrome with insulin resistance, characterize the disease pathogenesis, and establish a new theoretical basis for diagnosing, treating, and preventing polycystic ovary syndrome. METHODS Relevant scientific literature was covered from 1992 to 2020 by searching the PubMed database with search terms: insulin/insulin resistance, polycystic ovary syndrome, microRNAs, and metabolic diseases. References of relevant studies were cross-checked. RESULTS The related miRNAs (including differentially expressed miRNAs) and their roles in pathogenesis, and possible therapeutic targets and pathways, are discussed, highlighting controversies and offering thoughts for future directions. CONCLUSION We found abundant evidence on the role of differentially expressed miRNAs with its related phenotypes in PCOS. Considering the essential role of insulin resistance in the pathogenesis of PCOS, the alterations of associated miRNAs need more research attention. We speculate that race/ethnicity or PCOS phenotype and differences in methodological differences might lead to inconsistencies in research findings; thus, several miRNA profiles need to be investigated further to qualify for the potential therapeutic targets for PCOS-IR.

Abstract
The beneficial effects of metformin, especially its capacity to ameliorate insulin resistance (IR) in polycystic ovary syndrome (PCOS), explains why it is widely prescribed. However, its effect on the offspring of patients with PCOS remains uncertain. This study investigated the impact of metformin treatment on the first- and second-generation female offspring born to letrozole-induced PCOS-IR rats. Forty-five female Wistar rats were implanted with continuous-release letrozole pellets or placebo and treated with metformin or vehicle control. Rats exposed to letrozole showed PCOS-like reproductive, endocrine, and metabolic phenotypes in contrast to the controls. Metformin significantly decreased the risk of body weight gain and increased INSR expression in F1 female offspring in PCOS-IR rats, contributing to the improvement in obesity, hyperinsulinemia, and IR. Decreased FSHR expression and increased LHCGR expression were observed in F1 female rats of the PCOS-IR and PCOS-IR+Metformin groups, suggesting that FSHR and LHCGR dysfunction might promote the development of PCOS. Nevertheless, we found no significant differences in INSR, FSHR, and LHCGR expression or other PCOS phenotypes in F2 female offspring of PCOS-IR rats. These findings indicated widespread reproductive, endocrine, and metabolic changes in the PCOS-IR rat model, but the PCOS phenotypes could not be stably inherited by the next generations. Metformin might have contributed to the improvement in obesity, hyperinsulinemia, and IR in F1 female offspring. The results of this study could be used as a theoretical basis in support of using metformin in the treatment of PCOS-IR patients.

Abstract
Polycystic ovary syndrome (PCOS) is the most common gynecologic endocrine disorder in women between the ages of 15 and 40, with uncertain etiology. It is mostly presented with hyperandrogenism and insulin resistance along with a variety of comorbidities that significantly reduce a patient's quality of life. Many disturbed metabolic pathways are correlated with PCOS. Moreover, it is evident that there is a strong genetic factor for PCOS. Indeed, several altered gene expressions have been found in PCOS subjects, but the exact genetic origins are still unclear. The major treatment options such as pharmacological treatments are to improve the symptoms. In addition, surgical procedures (Bariatric surgery and assisted reproductive technologies) can be used to treat some of the patient's complications and reduce their severity. Generally, using pharmacological agents for a long period of time can increase the risk of adverse effects. Moreover, surgical options may have high-risk consequences. Herein, there is an undeniable need for a different multidisciplinary approach to PCOS. Regenerative medicine with the help of stem cells can develop a worthy alternative approach for the treatment of PCOS. Furthermore, animal models can provide valuable knowledge of genetic alterations and metabolic pathway disturbances in PCOS. They can also be used for testing novel treatments in pre-clinical stages. Therein, the current knowledge of PCOS and investigation about the potential role of regenerative medicine in developing new and more efficient treatments for PCOS are summarized here.

Evaluation of lipid ratios and triglyceride-glucose index as risk markers of insulin resistance in Iranian polycystic ovary syndrome women. Lipids Health Dis 2020; 19:235. [PMID: 33161896 PMCID: PMC7648985 DOI: 10.1186/s12944-020-01410-8] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Accepted: 10/20/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Insulin resistance has a vital role in the pathophysiology of polycystic ovary syndrome (PCOS). Previous investigations have shown that some lipid ratios could be a simple clinical indicator of insulin resistance (IR) in some disorders and ethnicities. The present study was conducted to evaluate the correlation between triglyceride to HDL-cholesterol (TG/HDL-C), total cholesterol to HDL-cholesterol (TC/HDL-C), as well as fasting triglyceride-glucose (TyG) indices with IR (as measured by homeostasis model assessment of IR (HOMA-IR), quantitative insulin sensitivity check index (QUICKI) and fasting glucose to insulin ratio (FGIR)) among the Iranian women diagnosed with PCOS. METHODS In the current study, a total of 305 women with PCOS were evaluated. TG/HDL-C, TC/HDL-C, and TyG indices were calculated. Fasting insulin level was measured using ELISA technique. IR was defined as a HOMA-IR value of ≥2.63, FG-IR value of < 8.25, and QUICKI value of < 0.33. RESULTS The insulin-resistant (IR) and insulin-sensitive (IS) groups, established by the HOMA-IR, FG-IR, and QUICKI values were different in terms of TG/HDL-C, TC/HDL-C, and TyG indices. These indices were associated with IR even after adjusting for age and BMI. ROC curve analyses showed that TyG, TG/HDL-C, and TC/HDL-C strongly predicted HOMA-IR with area under the curve (AUC) of 0.639, 0.619, and 0.623, respectively (P < 0.05). Further, TC/HDL-C was a good predictor of FG-IR with AUC of 0.614 (P = 0.04). CONCLUSION TyG, TG/HDL-C, and TC/HDL-C indices might be good indicators of IR among Iranian women diagnosed with PCOS.

Abstract
Introduction Hyperandrogenism (HA), either clinical or biochemical, is associated with obesity in adolescent girls. Long chain polyunsaturated fatty acids ω3 (LCPUFA-ω3) play protective roles in some obesity-associated morbidities, but their contribution to preventing HA is unclear. Our aim was to examine the potential positive relationships between erythrocyte LCPUFA-ω3, with or without supplementation, and hyperandrogenemia. Methods Secondary analysis of a clinical trial that was conducted previously to analyze the effect of LCPUFA-ω3 on insulin resistance and body weight. Here, we present a cross-sectional analysis of 180 girls with obesity, and a longitudinal analysis of 117 girls who completed a 3-month supplementation period (57 LCPUFA-ω3 [DO3] and 60 placebo [DP)]). Dehydroepiandrosterone sulfate (DHEAS), total testosterone (TT) and steroid hormone binding globulin (SHBG) were measured with chemiluminescence; free testosterone (FT) was calculated. Erythrocyte fatty acids were determined by gas chromatography. Non-parametric statistics was used for analysis. Results In cross-sectional analysis, age (odds ratio [OR] = 1.35; 95% confidence interval [CI] = 1.03, 1.78; p = 0.027), insulin (OR = 1.05; 95% CI: 1.00, 1.10; p = 0.018), and erythrocytes eicosapentaenoic acid (EPA) (OR = 0.04; 95% CI: 0.01, 0.65; p = 0.012) were predictors of hyperandrogenemia (FT >0.63 ng/mL). In longitudinal analysis, EPA, adiponectin and SHBG increased, while FT decreased, in the DO3 group (p < 0.05). The risk of hyperandrogenemia at the end of follow-up was predicted by basal hyperandrogenemia (OR = 18.16, 95% CI: 5.37, 61.4; p < 0.001) and by increases in EPA (OR = 0.40; 95% CI: 0.01, 0.65; p = 0.06 marginal significance). Conclusions Our results suggest a preventive role of EPA on the risk for hyperandrogenemia in girls with obesity, but further studies are needed to demonstrate a benefit.

Abstract
Polycystic ovary syndrome (PCOS) is a heterogeneous reproductive disease. Adipose mesenchymal stem cells (AMSCs) can produce a mass of exosomes. The objective of this study was to determine the effects of exosomal miR-323-3p on cumulus cells (CCs) of PCOS patients. Exosomal miR-323-3p were collected from modified AMSCs. Real-time PCR, western blots, MTT assays, flow cytometry, luciferase reporter assays and a letrozole-induced PCOS mouse model were used to identify mechanisms of exosomal miR-323-3p on CCs. The results revealed that miR-323-3p expression was upregulated in AMSCs, exosomes and CCs. Upregulated miR-323-3p promoted cell proliferation and suppressed apoptosis in CCs, while miR-323-3p inhibitor exerted opposite roles in exosome-treated CCs. Moreover, PDCD4 was upregulated in PCOS CCs, displayed an inverse expression pattern to those of miR-323-3p, and was a direct target of miR-323-3p. Overexpression of PDCD4 reversed the effects of upregulated miR-323-3p on CCs. Serum FSH, LH and testosterone were upregulated while E2 levels were downregulated in the PCOS mice. Upregulation of miR-323-3p alleviated PCOS by suppressing CCs' apoptosis through targeting PDCD4 in vivo. The results demonstrated that exosomal miR-323-3p promoted cell proliferation and inhibited apoptosis in CCs through targeting PDCD4 in PCOS. This study provides insight into developing new therapeutic strategies for PCOS.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16234816. [PMID: 31801197 PMCID: PMC6926786 DOI: 10.3390/ijerph16234816] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 11/26/2019] [Accepted: 11/28/2019] [Indexed: 12/17/2022]
Abstract
Background: Air pollutants cause endocrine disorders and hormone disruption. The relationship between air pollutants and polycystic ovary syndrome (PCOS) must be carefully investigated using a nationwide cohort. Methods: Data were extracted from two nationwide databases, namely Longitudinal Health Insurance Database and Taiwan Air Quality Monitoring Database, and analyzed. The study considered a range of data that began on 1 January 2000 and ended on 31 December 2013. Women diagnosed with PCOS were excluded. From the residential data, the study assessed the daily concentrations of sulfur dioxide (SO2), nitrogen oxides (NOx), nitrogen monoxide (NO), nitrogen dioxide (NO2), and PM2.5 the women were exposed to. A Cox proportional hazard regression model was applied to assess PCOS risk. Results: In total, 91,803 women were enrolled in this study; of those women, 2072 developed PCOS after 12 years of follow-up. The mean daily concentrations of SO2, NOx, NO, NO2, and PM2.5 women were exposed to were 4.25 (±1.44) ppb, 20.41 (±6.65) ppb, 9.25 (±4.36) ppb, 20.99 (±3.33) ppb, and 30.85 (±6.16) μg/m3, respectively. Compared with the first-quartile levels of exposure, the fourth-quartile levels of exposure to SO2, NOx, NO, NO2, and PM2.5 increased PCOS risk by 10.31 times (95% CI = 8.35–12.7), 3.37 times (95% CI = 2.86–3.96), 4.18 times (95% CI = 3.57–4.89), 7.46 times (95% CI = 6.38–8.71), and 3.56 times (95% CI = 3.05–4.15), respectively. Conclusion: Women exposed to a high concentrations of air pollutants, namely SO2, NO, NO2, NOx, and PM2.5, had a high PCOS risk.

Abstract
BACKGROUND Polycystic ovary syndrome is characterized by hyperactivity of the ovarian sympathetic nervous system, increases in the content and release of norepinephrine, as well as decreases in the number of β-adrenoreceptors. In the present study, β-adrenoreceptors in the ovaries of rats with polycystic ovary syndrome were blocked and analyzed the resultant effects on ovulation, hormone secretion and the enzymes responsible for the synthesis of catecholamines. METHODS At 60 days of age, vehicle or estradiol valerate-treated rats were injected with propranolol [10- 4 M] into the ovarian bursas on oestrus day. The animals were sacrificed on the next day of oestrus, and the ovulation response, the steroid hormone levels in the serum and the immunoreactivity of tyrosine hydroxylase and dopamine β-hydroxylase in the ovaries were measured. RESULTS In animals with the induction of polycystic ovary syndrome and β-adrenoreceptor blocking, ovulation was restored in more than half of the animals and resulted in decreased hyperandrogenism with respect to the levels observed in the estradiol valerate-treated group. Tyrosine hydroxylase and dopamine β-hydroxylase were present in the theca cells of the growing follicles and the interstitial gland. Injection of propranolol restored the tyrosine hydroxylase and ovarian dopamine β-hydroxylase levels in rats with polycystic ovary syndrome induction. CONCLUSIONS The results suggest that a single injection into the ovarian bursas of propranolol, a nonselective antagonist of β-adrenoreceptor receptors, decreases the serum testosterone concentration and the formation of ovarian cysts, improving the ovulation rate that accompanies lower levels of tyrosine hydroxylase and dopamine β-hydroxylase in the ovary.

Abstract
Background: Polycystic ovary syndrome is one of the most important factors in female infertility. Oxidative stress is likely to contribute to increased insulin and androgen production in the ovaries, as well as probably impairing follicle production. Aims: This study aims to determine the complementary effects of omega-3 and vitamin E supplements on certain oxidative stress indices in obese and overweight women with polycystic ovary syndrome. Materials and Methods: This double-blind, randomized clinical trial was performed on polycystic ovary syndrome subjects with BMI > 25. Patients were randomly allocated into two groups to receive either 2 g of omega-3 plus 400 IU of vitamin E, or a placebo, for 8 weeks. At the beginning and the end of the study, total antioxidant capacity, glutathione levels, catalase activity, malondialdehyde concentrations, as well as dietary intake and physical activity were evaluated. Statistical analysis was performed using SPSS. Results: 32 patients in the intervention group and 30 patients in the placebo group completed the study. Co-supplementation of omega-3 and vitamin E significantly increased total antioxidant capacity (mg/dl) (1.15 ± 0.93 vs -0.6 ± 0.72; P < 0.001), catalase activity (IU/L) (1.19 ± 1.06 vs 0.12 ± 0.36; P < 0.001) and glutathione levels (μmol/L) (1.5 ± 1.06 vs 0.23 ± 1.43; P = 0.028). Additionally, a significant reduction of malondialdehyde levels (nmol/L) (-0.34 ± 0.32 vs 0.57 ± 2.20; P = 0.008) was observed, in comparison with placebo. Conclusion: Co-supplementation with omega-3 and vitamin E had beneficial effect on total antioxidant capacity, malondialdehyde concentrations, glutathione levels and catalase activity.

Abstract
PURPOSE OF REVIEW We review the recent literature regarding the implications of gender on the diagnosis and treatment of autism spectrum disorder (ASD) in women and adolescent females. We also discuss important clinical observations in treating this population. RECENT FINDINGS Growing research supports gender specificity in ASD symptom presentation. Differing phenotypes, psychiatric co-morbidities, and level of "camouflaging" (behavioral coping strategies to conceal symptoms for use in social situations) are thought to further contribute to the discrepancy in prevalence rates and resulting misdiagnosis or delayed diagnosis in adolescent females and women. Both nosological and cultural factors appear to be contributing to differences in the diagnosis of ASD in women. These differences in presentation have important implications for late diagnosis, treatment of ASD, and the quality of life for women with autism.

Abstract
This study aimed to investigate the association between vitamin D (VitD) levels, polymorphisms in VDR gene (ApaI, BsmI, FokI, and TaqI) and the polycystic ovary syndrome (PCOS) in a group of Brazilian women. A total of 100 patients with PCOS and 100 control women were included. The quantification of 25-hydroxyvitamin D (25(OH)D) was performed in high-performance liquid chromatography (HPLC). Polymorphisms on VDR gene were performed by PCR-RFLP. The BsmI AG genotype was more frequent in PCOS group, while the GG genotype was more frequent in the control group (p = .007). The frequency of the Taql CC genotype was higher in PCOS group, while the CT genotype was the most frequent in the control group (p = .021). Mean serum VitD levels were similar between the groups. However, there was a negative correlation between VitD levels and Ferriman-Gallwey score (p = .031, r = -.260) in the PCOS group. The TaqI and BsmI polymorphisms were associated with PCOS. Moreover, VitD levels are associated with the clinical hyperandrogenism. The data suggest the role of VitD in PCOS development and its complications.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorder among females of reproductive age. Many emerging contaminants in personal care products have been confirmed with endocrine disruptive effects. We performed a case-control study to explore the association between the concentrations of certain emerging contaminants (organic UV filters, bisphenol A, and triclosan) and the risk of PCOS. Urine samples were collected from 40 women with PCOS (case group) and 83 healthy women (control group). No significant differences were found in detection rate or total concentrations of analytes in women with PCOS and controls (p > 0.05). In addition, no association was found between certain emerging contaminants and PCOS either in an unadjusted binary logistic regression model or in a model adjusted for potential confounders. However, with stratification according to body mass index, one organic UV filter - octocrylene(OC) was significantly associated with PCOS in women with BMI ≥ 24 (adjusted OR = 1.512, 95% CI: 1.043, 2.191). It's the first time to investigate the association between exposure of organic UV filters and PCOS risk. We conclude that there is positive association between OC and PCOS risk in obese and overweight women.

Abstract
Gonadotropin-releasing hormone (GnRH) modulators are widely used in numerous reproductive conditions including infertility. Several clinical studies showed mixed results regarding the efficacy of GnRH modulators in patients with polycystic ovary syndrome (PCOS). Along with this, few preclinical studies focus on the effect of GnRH modulators in PCOS-induced animals. Therefore, the present study was designed to study the effect of leuprolide and cetrorelix on hormonal, metabolic, and menstrual dysfunction PCOS rats. Prepubertal female rats were divided into four groups: Group I received a normal pellet diet and Groups II, III, and IV received 40% high-fat diet for 105 days. Similarly, adult female rats were divided into four groups: Group I received 1% carboxymethylcellulose (CMC) and Groups II, III, and IV received letrozole (1 mg/kg, per oral [p.o.] in 1% CMC) for 21 days. Thereafter, leuprolide (2.5 µg/rat, s.c.) and cetrorelix (10 µg/kg, subcutaneous [s.c.]) treatment were given to Group III and Group IV animals, respectively, for 21 days. Oral glucose tolerance test, lipid profile, fasting glucose, insulin, estrus cycle, hormonal profile, ovary weight, ovarian histopathological changes, and LHR and FSHR expressions were measured. Treatment with leuprolide and cetrorelix did not improve glucose intolerance, insulin level, insulin sensitivity indices, sex hormone levels, lipid profile, and estrus cycle. Only testosterone level, total cholesterol level, and follicular development were improved. Therefore, it was concluded that both leuprolide and cetrorelix showed improvement in follicular development, which could be helpful for improving fertility in PCOS.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a serious endocrine disorder. In the present study, we investigated the therapeutic effects of erdosteine in letrozole-induced PCOS in rats. METHODS Thirty-two Wistar albino female rats were grouped as control group (C), PCOS group (PCOS), PCOS-metformin group (PCOS+MET), and PCOS-erdosteine group (PCOS+Erd). PCOS was induced by administering letrozole; such rats presented with sex hormone disorder, abnormal estrous cycles determined by daily vaginal smear, large cystic follicles, and increasing fasting insulin levels. After induction of PCOS, metformin (500 mg/kg/day) and erdosteine (100 mg/kg/day) were given orally to the treatment groups for 30 days. Serum concentrations of glucose, total cholesterol, low- and high-density lipoprotein, triglyceride, as well as the total oxidant and antioxidant status, oxidative stress index, circulating estrone (E1), estradiol (E2), testosterone, and androstenedione were evaluated. The ovaries were graded histologically. RESULTS Weights of ovarian tissues (p < 0.05) and the number of atretic follicles (p < 0.001) and cystic follicles (p < 0.01) decreased in the PCOS+Erd group; the corpus luteum number was significantly higher in the PCOS+Erd group (p < 0.01) as compared with the PCOS group. Lipid parameters (total-C, LDL-C, and TG), E1 (estrone), E1/E2 ratio, testosterone, and androstenedione significantly decreased, while HDL-C and E2 (estradiol) significantly increased in the PCOS+Erd group as compared with the PCOS group. Moreover glucose, insulin, and HOMA-IR were reduced with treatment of erdosteine (p > 0.05, p < 0.001, and p < 0.001, respectively). CONCLUSION It is suggested that erdosteine may be used in the treatment of PCOS as an alternative to metformin. It appears that our findings might be supported by clinical and molecular studies.

Abstract
BACKGROUND Insulin sensitizers like metformin and pioglitazone are clinically used since last decades for the treatment of PCOS, but their efficacy and possible role in PCOS patients remains questionable. Also, the mechanism by which these insulin sensitizers show effect is not clear. AIM OF THE STUDY To evaluate the effect of metformin and pioglitazone on leutinizing hormone and follicle stimulating hormone receptor mRNA expression, hyperandrogenism and insulin resistance in high fat diet induced and letrozole induced PCOS in rats. METHODS Pre-pubertal female rats were divided into four groups: group I received normal pellet diet and group II, III and IV received high fat diet. After 105 d of dietary manipulation, metformin and pioglitazone treatment was given to group III and group IV animals respectively for 21 d. Similarly, adult female rats were divided into four groups: group I received 1% carboxymethyl cellulose (CMC) and group II, III, IV received letrozole for 21 d. After 21 d of letrozole administration, metformin and pioglitazone treatment was given to group III and group IV animals respectively for 21 d. Oral glucose tolerance test, lipid profile, fasting glucose, insulin, estrus cycle, hormonal profile, ovary weight, leutinizing hormone receptor and follicle stimulating hormone receptor mRNA expression was measured. Polycystic ovarian morphology was assessed through histopathological changes of ovary. RESULTS AND CONCLUSION Metformin and pioglitazone treatment improve both metabolic and reproductive parameters of PCOS including hyperinsulinemia and hyperandrogenism. LH receptor and FSH receptor mRNA expression were altered by pioglitazone and metformin treatment.

Abstract
Background: According to traditional herbal medicine, chamomile has been considered as one of the herbal remedies for patients with polycystic ovary syndrome (PCOS). The study aimed to investigate the effect of chamomile on lipid and hormonal parameters in women of reproductive age with PCOS. Materials and Methods: This study is a randomized clinical trial which was conducted on 80 women (40 patients in each group) of childbearing age with PCO. The intervention group received 370 mg oral capsules of chamomile three times a day for 3 months. The control group did receive starch capsule (three times a day). Hormonal and lipid parameters were examined before and 3 months after the intervention. Results: The mean age of the patients was 22.40 ± 5.10 and 24.38 ± 6.14 years in the intervention and control groups, respectively. Decreased level of testosterone was observed in the intervention group (in women with PCOS) who received chamomile capsules (P = 0.017). A significant difference was not seen in low-density lipoprotein cholesterol level (P = 0.249), high-density lipoprotein cholesterol (P = 0.073), triglycerides (P = 0.603), the hormone dehydroepiandrosterone sulfate (P = 0.423), and the ratio of luteinizing hormone/follicle-stimulating hormone (LH/FSH) in the experimental and control groups after the intervention (P = 0.420). Conclusion: According to the findings, oral administration of chamomile capsule caused a significant decrease in total testosterone levels in these patients. However, no significant change was reported with lipid parameters, the ratio of LH/FSH, and dehydroepiandrosterone sulfate level.

Abstract
Polycystic ovary syndrome (PCOS) is a common disorder in women in their reproductive years and is characterized by androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. It is also associated with several metabolic abnormalities, particularly insulin resistance and obesity, which play an important role in the pathophysiology of PCOS and, in particular, negatively influence ovarian function and fertility. This review article summarizes the available treatment for women with PCOS. Specifically, current and potentially new therapies are discussed.

Abstract
OBJECTIVE To compare age-associated changes in cardiovascular risk markers in lean and obese reproductive-aged women with polycystic ovary syndrome (PCOS) with community controls. DESIGN Longitudinal study at an academic medical centre PATIENTS: Patients diagnosed with PCOS by 2004 Rotterdam criteria in a multidisciplinary clinic were systematically enrolled from 2006-2014 in a PCOS cohort study and subsequently agreed to participate in a longitudinal study. The comparison controls were from the prospective, longitudinal Ovarian Aging (OVA) study, which consists of healthy women with regular menstrual cycles recruited from 2006 to 2011. MEASUREMENTS Cardiovascular risk markers and hormone parameters at baseline and follow-up. RESULTS Obese and lean PCOS (n = 38) and control women (n = 296) completed two study visits. The follow-up time (3.5 ± 1.5 vs 4.0 ± 0.8 years, P = .06) and magnitude of BMI gain (+0.1 kg/m2 /y [-0.11, 0.36] vs +0.26 [-0.18, 0.87] P = .19) did not differ between obese and lean PCOS and controls. In PCOS subjects, total testosterone decreased in both obese and lean, but the decrease was greater in obese subjects (-0.09 nmol/L per year; 95% CI: -0.16, -0.02 vs -0.04 nmol/L per year; 95%CI: -0.11, 0.03). Compared to their respective controls, obese and lean PCOS saw worsening triglyceride (TG) levels (P < .05) and HOMA-IR (P < .05) over time, but there was no difference in change in LDL, HDL, fasting glucose, C-reactive protein or ALT. CONCLUSIONS In a longitudinal study, reproductive-aged women with PCOS demonstrated declines in biochemical hyperandrogenaemia over time. Despite this, PCOS subjects experienced steeper increases in cardiovascular risk factors associated with insulin resistance, including triglycerides and HOMA-IR.

A Comparison of Sexual Function in Women with Polycystic Ovary Syndrome (PCOS) Whose Mothers Had PCOS During Their Pregnancy Period with Those Without PCOS. ARCHIVES OF SEXUAL BEHAVIOR 2017; 46:2033-2042.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during reproductive ages. Clinical symptoms associated with PCOS, such as hirsutism, acne, alopecia, obesity, and infertility, may lead to emotional morbidity and then impaired sexual function in those affected. During intrauterine development, the fetus may program the development of diseases during adulthood. In this study, we aimed to examine sexual function in women with PCOS, exposed to maternal androgen excess during their prenatal life compared to non-exposed PCOS patients. In this cross-sectional study, 768 married women with PCOS, aged 18-49 years, were subdivided into two groups, based on their mothers' PCOS status: women whose mothers had PCOS (N = 94) and women whose mothers did not have PCOS (N = 674). Data were collected using a questionnaire including information on demographics, anthropometric and reproductive characteristics, and the Female Sexual Function Index. Blood serum samples were collected from patients for assessment of total testosterone and sex hormone-binding globulin levels. Results revealed that sexual dysfunction was significantly higher in PCOS women whose mothers also had PCOS, compared to those whose mothers did not (38.6 vs. 25.3%, p = .01). After adjusting for confounding variables, logistic regression analysis showed that odds ratios for sexual dysfunction (total) and sexual dysfunction in the pain domain were significantly higher in the exposed PCOS women versus the non-exposed women (OR 1.81, 95% CI 1.06-3.07, p = .02 and 1.68, 95% CI 1.01-2.77, p = .04, respectively). Our study demonstrates increased sexual dysfunction in PCOS women whose mothers also had PCOS.

Abstract
OBJECTIVE Metformin has been used as a treatment option for polycystic ovary syndrome (PCOS) since 1994; however, more than a hundred randomized clinical trials have reported controversial results regarding the efficacy of metformin in PCOS. This could be due to the small sample size and high variability in methodology between studies. The objective of the present meta-analysis was to determine the effect of metformin on clinical, metabolic, and endocrine outcomes compared to placebo in PCOS women. METHODS Randomized controlled trials evaluating the efficacy of metformin were identified using a literature search in PubMed. Bibliographies of relevant studies were also screened to identify additional studies. Data was extracted from included studies and analyzed using RevMan software 5.3 from the Cochrane Collaboration. MAIN OUTCOME MEASURES Clinical outcomes included body mass index, waist to hip ratio, systolic and diastolic blood pressure and Ferriman-Gallway score. Metabolic outcomes included total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, very low-density lipoprotein, fasting blood glucose, fasting insulin levels, glucose insulin ratio, HOMA-IR and QUICKI. Endocrine outcomes such as serum testosterone, free testosterone, free androgen index, serum sex hormone binding globulin, dehydroepiandrosterone sulfate, luteinizing hormone, follicle stimulating hormone, LH/FSH ratio, estradiol, and progesterone levels. CONCLUSION Metformin showed significant improvement in clinical outcomes but not in metabolic and endocrine outcomes in PCOS women; however, heterogeneity between studies was found to be moderate to high.

Abstract
The aim of our study was to investigate the effects of a combined treatment with alpha-lipoic acid (ALA) and myoinositol (MYO) on clinical, endocrine and metabolic features of women affected by polycystic ovary syndrome (PCOS). In this pilot cohort study, forty women with PCOS were enrolled and clinical, hormonal and metabolic parameters were evaluated before and after a six-months combined treatment with ALA and MYO daily. Studied patients experienced a significant increase in the number of cycles in six months (p < 0.01). The free androgen index (FAI), the mean androstenedione and DHEAS levels significantly decreased after treatment (p < 0.05). Mean SHBG levels significantly raised (p < 0.01). A significant improvement in mean Ferriman-Gallwey (F-G) score (p < 0.01) and a significant reduction of BMI (p < 0.01) were also observed. A significant reduction of AMH levels, ovarian volume and total antral follicular count were observed in our studied women (p< 0.05). No significant changes occurred in gluco-insulinaemic and lipid parameters after treatment. The combined treatment of ALA and MYO is able to restore the menstrual pattern and to improve the hormonal milieu of PCOS women, even in the absence of apparent changes in insulin metabolism.

Abstract
Metformin is the most commonly prescribed drug for type 2 diabetes mellitus. In recent years, in addition to glucose lowering, several studies have presented evidence suggesting some potential role for metformin, such as antitumor effect, antiaging effect, cardiovascular protective effect, neuroprotective effect or an optional treatment for polycystic ovary syndrome. This paper will critically review the role of metformin to provide reference for doctors and researchers.

Kaohsiung J Med Sci 2017; 33:558-566.

Abstract
This study investigated the relationship between the CYP19 alleles, rs727479A/C, rs700518A/G, and rs700519C/T, and pregnancy outcome after assisted reproductive technology (ART) in patients with polycystic ovary syndrome (PCOS). Between January 2012 and September 2015, 293 PCOS patients undergoing ART were randomly selected for the study. According to pregnancy outcome after ART, the patients were assigned to pregnancy and non-pregnancy groups. CYP19 rs727479A/C, rs700518A/G and rs700519C/T genotypes were determined using the denaturing high-performance liquid chromatography (DHPLC) method. Haplotype frequencies of the CYP19 alleles rs727479A/C, rs700518A/G and rs700519C/T were estimated using the SHEsis platform. Logistic regression analysis was employed to analyze the factors influencing the pregnancy outcome after ART. The frequency of the AC + CC genotype of rs727479A/C was higher in the pregnancy group than in the non-pregnancy group. The frequency of the CT + TT genotype of rs700519A/G was also higher in the pregnancy group than in the non-pregnancy group. Haplotype analysis indicated that the AAC and AGT haplotypes both exhibited unfavorable influence on the pregnancy outcome after ART. The AAT and CGT haplotypes were favorable to the pregnancy outcome after ART. Logistic regression analysis suggested that the rs727479A/C AA genotype, the rs700519C/T CC genotype and body mass index (BMI) might exert unfavorable influence on the pregnancy outcome after ART for PCOS patients. These findings indicated that the CYP19 alleles rs727479A/C and rs700519C/T might be associated with the pregnancy outcome after ART in patients with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is characterized by hormonal abnormalities that cause menstrual irregularity and reduce ovulation rate and fertility, associated to insulin resistance. Myo-inositol (cis-1,2,3,5-trans-4,6-cyclohexanehexol, MI) and D-chiro-inositol (cis-1,2,4-trans-3,5,6-cyclohexanehexol, DCI) represent promising treatments for PCOS, having shown some therapeutic benefits without substantial side effects. Because the use of inositols for treating PCOS is widespread, a deep understanding of this treatment option is needed, both in terms of potential mechanisms and efficacy. This review summarizes the current knowledge on the biological effects of MI and DCI and the results obtained from relevant intervention studies with inositols in PCOS. Based on the published results, both MI and DCI represent potential valid therapeutic approaches for the treatment of insulin resistance and its associated metabolic and reproductive disorders, such as those occurring in women affected by PCOS. Furthermore, the combination MI/DCI seems also effective and might be even superior to either inositol species alone. However, based on available data, a particular MI:DCI ratio to be administered to PCOS patients cannot be established. Further studies are then necessary to understand the real contents of MI or DCI uptaken by the ovary following oral administration in order to identify optimal doses and/or combination ratios.

Abstract
The objective of the study was to investigate the effects of 6 months of melatonin administration on clinical, endocrine, and metabolic features of women affected by polycystic ovary syndrome (PCOS). This is a prospective cohort study including 40 normal-weight women with PCOS between January and September 2016, enrolled in an academic research environment. Ultrasonographic pelvic examinations, hirsutism score evaluation, hormonal profile assays, oral glucose tolerance test, and lipid profile at baseline and after 6 months of melatonin administration were performed. Melatonin treatment significantly decreased androgens levels (free androgen index: P < .05; testosterone: P < .01; 17 hydroxyprogesterone: P < .01). Follicle-stimulating hormone levels significantly raised ( P < .01), and anti-Mullerian hormone serum levels significantly dropped after 6 months of melatonin treatment ( P < .01). No significant changes occurred in glucoinsulinemic and lipid parameters after treatment except a significant decrease of low-density lipoprotein cholesterol. Almost 95% of participants experienced an amelioration of menstrual cycles. Until now, only few data have been published about the role of melatonin in women with PCOS. This is the first study focused on the effects of exogenous oral melatonin administration on the clinical, endocrine, and metabolic characteristics of patients with PCOS. After 6 months of treatment, melatonin seems to improve menstrual irregularities and biochemical hyperandrogenism in women with PCOS through a direct, insulin-independent effect on the ovary. Based on our results, melatonin could be considered a potential future therapeutic agent for women affected by PCOS.

Abstract
The polycystic ovary syndrome (PCOS) is a complex and heterogeneous endocrine disorder. MicroRNAs negatively regulate the expression of target genes at posttranscriptional level by binding to the 3' untranslated region of target genes. Our previous study showed that miR-141-3p was dramatically decreased in the ovaries of rat PCOS models. In this study, we aimed to characterize the target of miR-141-3p in rat ovarian granulosa cells. 3-(4,5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay showed that cell viability was dramatically increased when miR-141-3p was overexpressed but was decreased when miR-141-3p was interfered. Flow cytometry showed that cell apoptotic rate was dramatically decreased when miR-141-3p was overexpressed but was increased when miR-141-3p was interfered. Bioinformatics analysis predicted that death-associated protein kinase 1 (DAPK1) might be the target gene of miR-141-3p because the 3' untranslated region of DAPK1 contains sequences complementary to microRNA-141-3p. Transfection with miR-141-3p mimics and inhibitor into granulosa cells showed that both DAPK1 mRNA and protein levels were negatively correlated with miR-141-3p level. Dual-luciferase reporter assay established that DAPK1 was the target of miR-141-3p. Taken together, our data indicate that miR-141-3p may inhibit ovarian granulosa cell apoptosis via targeting DAPK1 and is involved in the etiology of PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is the most common cause of female infertility worldwide. Although the related research output is constantly growing, no detailed global map of the scientific architecture has so far been created encompassing quantitative, qualitative, socioeconomic and gender aspects. We used the NewQIS platform to assess all PCOS-related publications indexed between 1900 and 2014 in the Web of Science, and applied density equalizing mapping projections, scientometric techniques and economic benchmarking procedures. A total of 6261 PCOS-specific publications and 703 international research collaborations were found. The USA was identified as the most active country in total and collaborative research activity. In the socioeconomic analysis, the USA was also ranked first (25.49 PCOS-related publications per gross domestic product [GDP]/capita), followed by the UK, Italy and Greece. When research activity was related to population size, Scandinavian countries and Greece were leading the field. For many highly productive countries, gender analysis revealed a high ratio of female scientists working on PCOS with the exception of Japan. In this study, we have created the first picture of global PCOS research, which largely differs from other gynaecologic conditions and indicates that most related research and collaborations originate from high-income countries.

Abstract
To investigate the serum concentrations of organochlorine pesticides (OCPs) in patients with polycystic ovary syndrome (PCOS), a total of 178 women were studied. The concentrations of hexachlorocyclohexane (HCH) and dichlorodiphenyltrichloroethane (DDT) in serum were determined using Gas Chromatography Mass-Mass Spectrometer. No differences with statistical significance in the mean HCH, p,p'-DDD, p,p'-DDE concentrations were observed between the patients with PCOS and the control group. Serum p,p'-DDT (P = 0.016) and o,p'-DDT (P = 0.000) levels were significantly higher in patients with PCOS compared with the control group. The results of the association between OCPs levels and hormone levels indicated that o,p'-DDT may play a role in the pathogenesis of PCOS by affecting hormones levels. Further trials should be investigated with the findings in this study to obtain new pathogenesis of PCOS.

Metabolic consequences of obesity and insulin resistance in polycystic ovary syndrome: diagnostic and methodological challenges. Nutr Res Rev 2017; 30:97-105.

Abstract
Women with polycystic ovary syndrome (PCOS) have a considerable risk of metabolic dysfunction. This review aims to present contemporary knowledge on obesity, insulin resistance and PCOS with emphasis on the diagnostic and methodological challenges encountered in research and clinical practice. Variable diagnostic criteria for PCOS and associated phenotypes are frequently published. Targeted searches were conducted to identify all available data concerning the association of obesity and insulin resistance with PCOS up to September 2016. Articles were considered if they were peer reviewed, in English and included women with PCOS. Obesity is more prevalent in women with PCOS, but studies rarely reported accurate assessments of adiposity, nor split the study population by PCOS phenotypes. Many women with PCOS have insulin resistance, though there is considerable variation reported in part due to not distinguishing subgroups known to have an impact on insulin resistance as well as limited methodology to measure insulin resistance. Inflammatory markers are positively correlated with androgen levels, but detailed interactions need to be identified. Weight management is the primary therapy; specific advice to reduce the glycaemic load of the diet and reduce the intake of pro-inflammatory SFA and advanced glycation endproducts have provided promising results. It is important that women with PCOS are educated about their increased risk of metabolic complications in order to make timely and appropriate lifestyle modifications. Furthermore, well-designed robust studies are needed to evaluate the mechanisms behind the improvements observed with dietary interventions.
