Abstract
Despite affecting ~11-13% of women globally, polycystic ovary syndrome (PCOS) is a substantially understudied condition. PCOS, possibly extending to men's health, imposes a considerable health and economic burden worldwide. Diagnosis in adults follows the International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome, requiring two out of three criteria - clinical or biochemical hyperandrogenism, ovulatory dysfunction, and/or specific ovarian morphological characteristics or elevated anti-Müllerian hormone. However, diagnosing adolescents omits ovarian morphology and anti-Müllerian hormone considerations. PCOS, marked by insulin resistance and hyperandrogenism, strongly contributes to early-onset type 2 diabetes, with increased odds for cardiovascular diseases. Reproduction-related implications include irregular menstrual cycles, anovulatory infertility, heightened risks of pregnancy complications and endometrial cancer. Beyond physiological manifestations, PCOS is associated with anxiety, depression, eating disorders, psychosexual dysfunction and negative body image, collectively contributing to diminished health-related quality of life in patients. Despite its high prevalence persisting into menopause, diagnosing PCOS often involves extended timelines and multiple health-care visits. Treatment remains ad hoc owing to limited understanding of underlying mechanisms, highlighting the need for research delineating the aetiology and pathophysiology of the syndrome. Identifying factors contributing to PCOS will pave the way for personalized medicine approaches. Additionally, exploring novel biomarkers, refining diagnostic criteria and advancing treatment modalities will be crucial in enhancing the precision and efficacy of interventions that will positively impact the lives of patients.

Abstract
The mouse estrous cycle is divided into four stages: proestrus (P), estrus (E), metestrus (M) and diestrus (D). The estrous cycle affects reproductive hormone levels in a wide variety of tissues. Therefore, to obtain reliable results from female mice, it is important to know the estrous cycle stage during sampling. The stage can be analyzed from a vaginal smear under a microscope. However, it is time-consuming, and the results vary between evaluators. Here, we present an accurate and reproducible method for staging the mouse estrous cycle in digital whole slide images (WSIs) of vaginal smears. We developed a model using a deep convolutional neural network (CNN) in a cloud-based platform, Aiforia Create. The CNN was trained by supervised pixel-level multiclass semantic segmentation of image features from 171 hematoxylin-stained samples. The model was validated by comparing the results obtained by CNN with those of four independent researchers. The validation data included three separate studies comprising altogether 148 slides. The total agreement attested by the Fleiss kappa value between the validators and the CNN was excellent (0.75), and when D, E and P were analyzed separately, the kappa values were 0.89, 0.79 and 0.74, respectively. The M stage is short and not well defined by the researchers. Thus, identification of the M stage by the CNN was challenging due to the lack of proper ground truth, and the kappa value was 0.26. We conclude that our model is reliable and effective for classifying the estrous cycle stages in female mice.

Abstract
Background Polycystic ovary syndrome's (PCOS) main feature is hyperandrogenism, which is linked to a higher risk of metabolic disorders. Gene expression analyses in adipose tissue and skeletal muscle reveal dysregulated metabolic pathways in women with PCOS, but these differences do not necessarily lead to changes in protein levels and biological function. Methods To advance our understanding of the molecular alterations in PCOS, we performed global proteomic and phosphorylation site analysis using tandem mass spectrometry, and analyzed gene expression and methylation. Adipose tissue and skeletal muscle were collected at baseline from 10 women with and without PCOS, and in women with PCOS after 5 weeks of treatment with electrical stimulation. Results Perilipin-1, a protein that typically coats the surface of lipid droplets in adipocytes, was increased whereas proteins involved in muscle contraction and type I muscle fiber function were downregulated in PCOS muscle. Proteins in the thick and thin filaments had many altered phosphorylation sites, indicating differences in protein activity and function. A mouse model was used to corroborate that androgen exposure leads to a shift in muscle fiber type in controls but not in skeletal muscle-specific androgen receptor knockout mice. The upregulated proteins in muscle post treatment were enriched in pathways involved in extracellular matrix organization and wound healing, which may reflect a protective adaptation to repeated contractions and tissue damage due to needling. A similar, albeit less pronounced, upregulation in extracellular matrix organization pathways was also seen in adipose tissue. Conclusions Our results suggest that hyperandrogenic women with PCOS have higher levels of extra-myocellular lipids and fewer oxidative insulin-sensitive type I muscle fibers. These could be key factors leading to insulin resistance in PCOS muscle while electric stimulation-induced tissue remodeling may be protective.

Abstract
Polycystic ovary syndrome (PCOS) is associated with symptoms of moderate to severe anxiety and depression. Hyperandrogenism is a key feature together with lower levels of the adipocyte hormone adiponectin. Androgen exposure leads to anxiety-like behavior in female offspring while adiponectin is reported to be anxiolytic. Here we test the hypothesis that elevated adiponectin levels protect against the development of androgen-induced anxiety-like behavior. Pregnant mice overexpressing adiponectin (APNtg) and wildtypes were injected with vehicle or dihydrotestosterone to induce prenatal androgenization (PNA) in the offspring. Metabolic profiling and behavioral tests were performed in 4-month-old female offspring. PNA offspring spent more time in the closed arms of the elevated plus maze, indicating anxiety-like behavior. Intriguingly, neither maternal nor offspring adiponectin overexpression prevented an anxiety-like behavior in PNA-exposed offspring. However, adiponectin overexpression in dams had metabolic imprinting effects, shown as lower fat mass and glucose levels in their offspring. While serum adiponectin levels were elevated in APNtg mice, cerebrospinal fluid levels were similar between genotypes. Adiponectin overexpression improved metabolic functions but did not elicit anxiolytic effects in PNA-exposed offspring. These observations might be attributed to increased circulating but unchanged cerebrospinal fluid adiponectin levels in APNtg mice. Thus, increased adiponectin levels in the brain are likely needed to stimulate anxiolytic effects.

Abstract
OBJECTIVE To assess differences in body image concerns among women with and without polycystic ovary syndrome (PCOS). DESIGN This is a systematic review and meta-analysis. METHODS Electronic databases (MEDLINE, EMBASE, APA PsychInfo, PUBMED, Web-of-Science Core Collection, and Cochrane Controlled Register of Trials [CENTRAL]) were searched from inception through July 2022. Outcome measures included validated questionnaires reporting on body image concerns. Methodological quality was assessed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system, and included studies were assessed for risk of bias. Meta-analyses were performed using the inverse variance method based on random or fixed effects models (Review Manager, Version 5). RESULTS A total of 918 women with PCOS and 865 women without PCOS from 9 studies were included. Meta-analysis of 3 studies using Multidimensional Body-Self Relations Questionnaire Appearance Scale (MBSRQ-AS) showed those with PCOS reported higher dissatisfaction with appearance evaluation and appearance orientation compared to those without PCOS (mean difference [MD] = -0.78, I2 = 0%, P < .00001, and MD = 0.22, I2 = 54%, P = .004, respectively). Meta-analysis of 2 studies showed higher dissatisfaction with overweight preoccupation, lower body area satisfaction, and body weight classification on MBSRQ-AS subscales in those with PCOS compared to those without PCOS (all P < .001). Meta-analysis of 2 studies using the Body Esteem Scale for Adolescents and Adults (BESAA) showed significantly lower scores for the weight subscale in those with PCOS compared to those without PCOS (P = .03). CONCLUSIONS Those with PCOS experience more significant body image concerns, emphasising the importance of awareness in the clinical care of PCOS. Considering the limited evidence, further studies are warranted to identify drivers and mitigating factors.

Abstract
Variations in B cell numbers are associated with polycystic ovary syndrome (PCOS) through unknown mechanisms. Here we demonstrate that B cells are not central mediators of PCOS pathology and that their frequencies are altered as a direct effect of androgen receptor activation. Hyperandrogenic women with PCOS have increased frequencies of age-associated double-negative B memory cells and increased levels of circulating immunoglobulin M (IgM). However, the transfer of serum IgG from women into wild-type female mice induces only an increase in body weight. Furthermore, RAG1 knock-out mice, which lack mature T- and B cells, fail to develop any PCOS-like phenotype. In wild-type mice, co-treatment with flutamide, an androgen receptor antagonist, prevents not only the development of a PCOS-like phenotype but also alterations of B cell frequencies induced by dihydrotestosterone (DHT). Finally, B cell-deficient mice, when exposed to DHT, are not protected from developing a PCOS-like phenotype. These results urge further studies on B cell functions and their effects on autoimmune comorbidities highly prevalent among women with PCOS.

Abstract
The transgenerational maternal effects of polycystic ovary syndrome (PCOS) in female progeny are being revealed. As there is evidence that a male equivalent of PCOS may exists, we ask whether sons born to mothers with PCOS (PCOS-sons) transmit reproductive and metabolic phenotypes to their male progeny. Here, in a register-based cohort and a clinical case-control study, we find that PCOS-sons are more often obese and dyslipidemic. Our prenatal androgenized PCOS-like mouse model with or without diet-induced obesity confirmed that reproductive and metabolic dysfunctions in first-generation (F1) male offspring are passed down to F3. Sequencing of F1-F3 sperm reveals distinct differentially expressed (DE) small non-coding RNAs (sncRNAs) across generations in each lineage. Notably, common targets between transgenerational DEsncRNAs in mouse sperm and in PCOS-sons serum indicate similar effects of maternal hyperandrogenism, strengthening the translational relevance and highlighting a previously underappreciated risk of transmission of reproductive and metabolic dysfunction via the male germline.

Abstract
BACKGROUND Dysregulation of circulating lipids is a central element for the metabolic syndrome. However, it is not well established whether human subcutaneous adipose tissue is affected by or affect circulating lipids through epigenetic mechanisms. Hence, our aim was to investigate the association between circulating lipids and DNA methylation levels in human adipose tissue. METHODS DNA methylation and gene expression were analyzed genome-wide in subcutaneous adipose tissue from two different cohorts, including 85 men and 93 women, respectively. Associations between DNA methylation and circulating levels of triglycerides, LDL, HDL and total cholesterol were analysed. Causal mediation analyses tested if adipose tissue DNA methylation mediates the effects of triglycerides on gene expression or insulin resistance. RESULTS We found 115 novel associations between triglycerides and adipose tissue DNA methylation, e.g. in the promoter of RFS1, ARID2, and HOXA5 in the male cohort (p ≤ 1.1x10-7), and 63 associations e.g. within the gene body of PTPRN2 and COL6A3 in the female cohort. We further connected these findings to altered mRNA expression levels in adipose tissue (e.g. HOXA5, IL11 and FAM45B). Interestingly, there was no overlap between methylation sites associated with triglycerides in men and the sites found in women, which points towards sex-specific effects of triglycerides on the epigenome. Finally, a causal mediation analysis provided support for adipose tissue DNA methylation as a partial mediating factor between circulating triglycerides and insulin resistance. CONCLUSIONS This study identified novel epigenetic alterations in adipose tissue associated with circulating lipids. Identified epigenetic changes seem to mediate effects of triglycerides on insulin resistance.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder, which is accompanied by a variety of comorbidities including metabolic, reproductive, and psychiatric disorders. Genome-wide association studies have identified several genetic variants that are associated with PCOS. However, these variants often occur outside of coding regions and require further investigation to understand their contribution to PCOS. A transcriptome-wide association study (TWAS) was performed to uncover heritable gene expression profiles that are associated with PCOS in two independent cohorts. Causal gene prioritization was subsequently performed and expression of genes prioritized through these analyses was examined in 49 PCOS patients and 30 controls. TWAS analyses revealed that increased expression of ARL14EP was significantly associated with PCOS risk in the discovery (P = 1.6 × 10-6) and replication cohorts (P = 2.0 × 10-13). Gene prioritization pipelines provided further evidence that ARL14EP is the most likely causal gene at this locus. ARL14EP gene expression was shown to be significantly different between PCOS cases and controls, after adjusting for body mass index, age and testosterone levels (P = 1.2 × 10-13). This study has provided evidence for the role of ARL14EP in PCOS. Given that ARL14EP has been reported to play an important role in chromatin remodeling, variants affecting the expression of ARL14EP may also affect the expression of other genes that contribute to PCOS pathogenesis.

Abstract
Excessive androgen production and obesity are key to polycystic ovary syndrome (PCOS) pathogenesis. Prenatal androgenized (PNA), peripubertal androgenized, and overexpression of nerve growth factor in theca cells (17NF) are commonly used PCOS-like mouse models and diet-induced maternal obesity model is often included for comparsion. To reveal the molecular features of these models, we have performed transcriptome survey of the hypothalamus, adipose tissue, ovary and metaphase II (MII) oocytes. The largest number of differentially expressed genes (DEGs) is found in the ovaries of 17NF and in the adipose tissues of peripubertal androgenized models. In contrast, hypothalamus is most affected in PNA and maternal obesity models suggesting fetal programming effects. The Ms4a6e gene, membrane-spanning 4-domains subfamily A member 6E, a DEG identified in the adipose tissue in all mouse models is also differently expressed in adipose tissue of women with PCOS, highlighting a conserved disease function. Our comprehensive transcriptomic profiling of key target tissues involved in PCOS pathology highlights the effects of developmental windows for androgen exposure and maternal obesity, and provides unique resource to investigate molecular mechanisms underlying PCOS pathogenesis.

Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) have high circulating anti-Müllerian hormone (AMH) levels which is correlated with antral follicle count and polycystic ovarian morphology and negatively correlated with body mass index (BMI). Moreover, diet-induced weight loss in women with PCOS and overweight or obesity, reduce or normalize AMH-levels. There is, however, no previous study investigating the circulating AMH levels in women with severe obesity and how a structured diet-induced weight loss program affects circulating AMH levels in these women. Therefore, this study aims to investigate circulating AMH levels in a population of women with severe obesity (BMI ≥ 35 kg/m2) with and without PCOS, as diagnosed by the NIH-criteria, and to investigate the effect of a one-year weight loss program with a very low-energy diet (VLED) on circulating levels of AMH. METHODS In a prospective cohort-study, were 246 women with severe obesity were screened for PCOS diagnosis with the NIH-criteria, circulating AMH and anthropometry were measured at baseline and after a 12-month weight loss intervention with very low-energy diet (VLED). RESULTS Mean BMI was 39.9 ± 4.7 (PCOS), 39.6 ± 4.3 (non-PCOS) P = 0.960. Circulating AMH was higher in women with PCOS (5.47 ± 4.89 µg/L) compared with non-PCOS (2.66 ± 3.71 µg/L) P < 0.001 and was positively correlated with circulating total testosterone in both groups. Next, we performed ROC-analyses, and show that circulating AMH could not discriminate women with PCOS and severe obesity from non-PCOS women with severe obesity. Finally, a one-year weight reduction program does not affect circulating AMH levels despite significant weight loss neither in women with PCOS, nor without PCOS and severe obesity. CONCLUSION Women with severe obesity and PCOS have elevated levels of circulating AMH compared to women without the syndrome. AMH-levels could not discriminate women with PCOS from non-PCOS because of low sensitivity and specificity. Significant weight loss was not associated with changes in circulating AMH levels, neither in women with, nor without PCOS and severe obesity. These results imply that in women with severe obesity, a greater weight loss may be needed to improve reproductive features, independent of PCOS diagnosis.

Abstract
Polycystic ovary syndrome (PCOS) is a complex disease affecting up to 15% of women of reproductive age. Women with PCOS suffer from reproductive dysfunctions with excessive androgen secretion and irregular ovulation, leading to reduced fertility and pregnancy complications. The syndrome is associated with a wide range of comorbidities including type 2 diabetes, obesity, and psychiatric disorders. Despite the high prevalence of PCOS, its etiology remains unclear. To understand the pathophysiology of PCOS, how it is inherited, and how to predict PCOS, and prevent and treat women with the syndrome, animal models provide an important approach to answering these fundamental questions. This minireview summarizes recent investigative efforts on PCOS-like rodent models aiming to define underlying mechanisms of the disease and provide guidance in model selection. The focus is on new genetic rodent models, on a naturally occurring rodent model, and provides an update on prenatal and peripubertal exposure models.

Abstract
Polycystic ovary syndrome (PCOS) affects 5-18% of women, and is a reproductive, metabolic, and psychological condition with impacts across the lifespan. The cause is complex, and includes genetic and epigenetic susceptibility, hypothalamic and ovarian dysfunction, excess androgen exposure, insulin resistance, and adiposity-related mechanisms. Diagnosis is recommended based on the 2003 Rotterdam criteria and confirmed with two of three criteria: hyperandrogenism (clinical or biochemical), irregular cycles, and polycystic ovary morphology. In adolescents, both the criteria of hyperandrogenism and irregular cycles are needed, and ovarian morphology is not included due to poor specificity. The diagnostic criteria generates four phenotypes, and clinical features are heterogeneous, with manifestations typically arising in childhood and then evolving across adolescent and adult life. Treatment involves a combination of lifestyle alterations and medical management. Lifestyle optimisation includes a healthy balanced diet and regular exercise to prevent excess weight gain, limit PCOS complications and target weight reduction when needed. Medical management options include metformin to improve insulin resistance and metabolic features, combined oral contraceptive pill for menstrual cycle regulation and hyperandrogenism, and if needed, anti-androgens for refractory hyperandrogenism. In this Review, we provide an update on the pathophysiology, diagnosis, and clinical features of PCOS, and discuss the needs and priorities of those with PCOS, including lifestyle, and medical and infertility treatment. Further we discuss the status of international evidence-based guidelines (EBG) and translation, to support patient self management, healthcare provision, and to set research priorities.

Abstract
AIMS/HYPOTHESIS The link underlying abnormal glucose metabolism, type 2 diabetes and polycystic ovary syndrome (PCOS) that is independent of BMI remains unclear in observational studies. We aimed to clarify this association using a genome-wide cross-trait approach. METHODS Summary statistics from the hitherto largest genome-wide association studies conducted for type 2 diabetes, type 2 diabetes mellitus adjusted for BMI (T2DMadjBMI), fasting glucose, fasting insulin, 2h glucose after an oral glucose challenge (all adjusted for BMI), HbA1c and PCOS, all in populations of European ancestry, were used. We quantified overall and local genetic correlations, identified pleiotropic loci and expression-trait associations, and made causal inferences across traits. RESULTS A positive overall genetic correlation between type 2 diabetes and PCOS was observed, largely influenced by BMI (rg=0.31, p=1.63×10-8) but also independent of BMI (T2DMadjBMI-PCOS: rg=0.12, p=0.03). Sixteen pleiotropic loci affecting type 2 diabetes, glycaemic traits and PCOS were identified, suggesting mechanisms of association that are independent of BMI. Two shared expression-trait associations were found for type 2 diabetes/T2DMadjBMI and PCOS targeting tissues of the cardiovascular, exocrine/endocrine and digestive systems. A putative causal effect of fasting insulin adjusted for BMI and type 2 diabetes on PCOS was demonstrated. CONCLUSIONS/INTERPRETATION We found a genetic link underlying type 2 diabetes, glycaemic traits and PCOS, driven by both biological pleiotropy and causal mediation, some of which is independent of BMI. Our findings highlight the importance of controlling fasting insulin levels to mitigate the risk of PCOS, as well as screening for and long-term monitoring of type 2 diabetes in all women with PCOS, irrespective of BMI.

Abstract
BACKGROUND The comorbidity between polycystic ovary syndrome (PCOS) and obesity has long been observed in clinical settings, but their shared genetic basis remains unclear. METHODS Leveraging summary statistics of large-scale GWAS(s) conducted in European-ancestry populations on body mass index (adult BMI, Nfemale=434,794; childhood BMI, N=39,620), waist-to-hip ratio (WHR, Nfemale=381,152), WHR adjusted for BMI (WHRadjBMI, Nfemale=379,501), and PCOS (Ncase=10,074, Ncontrol=103,164), we performed a large-scale genome-wide cross-trait analysis to quantify overall and local genetic correlation, to identify shared loci, and to infer causal relationship. RESULTS We found positive genetic correlations between PCOS and adult BMI (rg=0.47, P=2.19×10-16), childhood BMI (rg=0.31, P=6.72×10-5), and WHR (rg=0.32, P=1.34×10-10), all withstanding Bonferroni correction. A suggestive significant genetic correlation was found between PCOS and WHRadjBMI (rg=0.09, P=0.04). Partitioning the whole genome into 1703 nearly independent regions, we observed a significant local genetic correlation for adult BMI and PCOS at chromosome 18: 57630483-59020751. We identified 16 shared loci underlying PCOS and obesity-related traits via cross-trait meta-analysis including 9 loci shared between BMI and PCOS (adult BMI and PCOS: 5 loci; childhood BMI and PCOS: 4 loci), 6 loci shared between WHR and PCOS, and 5 loci shared between WHRadjBMI and PCOS. Mendelian randomization (MR) supported the causal roles of both adult BMI (OR=2.92, 95% CI=2.33-3.67) and childhood BMI (OR=2.76, 95% CI=2.09-3.66) in PCOS, but not WHR (OR=1.19, 95% CI=0.93-1.52) or WHRadjBMI (OR=1.03, 95% CI=0.87-1.22). Genetic predisposition to PCOS did not seem to influence the risk of obesity-related traits. CONCLUSIONS Our cross-trait analysis suggests a shared genetic basis underlying obesity and PCOS and provides novel insights into the biological mechanisms underlying these complex traits. Our work informs public health intervention by confirming the important role of weight management in PCOS prevention.

Abstract
STUDY QUESTION Does acupuncture improve insulin sensitivity more effectively than metformin or sham acupuncture in women with polycystic ovary syndrome (PCOS) and insulin resistance (IR)? SUMMARY ANSWER Among women with PCOS and IR, acupuncture was not more effective than metformin or sham acupuncture in improving insulin sensitivity. WHAT IS KNOWN ALREADY Uncontrolled trials have shown that acupuncture improved insulin sensitivity with fewer side effects compared with metformin in women with PCOS and IR. However, data from randomized trials between acupuncture and metformin or sham acupuncture are lacking. STUDY DESIGN, SIZE, DURATION This was a three-armed randomized controlled trial enrolling a total of 342 women with PCOS and IR from three hospitals between November 2015 and February 2018, with a 3-month follow-up until October 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS Women aged from 18 to 40 years with PCOS and homeostasis model assessment of insulin resistance (HOMA-IR) ≥2.14 were randomly assigned (n = 114 per group) to receive true acupuncture plus placebo (true acupuncture), metformin plus sham acupuncture (metformin, 0.5 g three times daily) or sham acupuncture plus placebo (sham acupuncture) for 4 months, with an additional 3-month follow-up. True or sham acupuncture was given three times per week, and 0.5 g metformin or placebo was given three times daily. The primary outcome was change in HOMA-IR from baseline to 4 months after baseline visit. Secondary outcomes included changes in the glucose AUC during an oral glucose tolerance test, BMI and side effects at 4 months after baseline visit. MAIN RESULTS AND THE ROLE OF CHANCE After 4 months of treatment, the changes of HOMA-IR were -0.5 (decreased 14.7%) in the true acupuncture group, -1.0 (decreased 25.0%) in the metformin group and -0.3 (decreased 8.6%) in the sham acupuncture group, when compared with baseline. True acupuncture is not as effective as metformin in improving HOMA-IR at 4 months after baseline visit (difference, 0.6; 95% CI, 0.1-1.1). No significant difference was found in change in HOMA-IR between true and sham acupuncture groups at 4 months after baseline visit (difference, -0.2; 95% CI, -0.7 to 0.3). During the 4 months of treatment, gastrointestinal side effects were more frequent in the metformin group, including diarrhea, nausea, loss of appetite, fatigue, vomiting and stomach discomfort (31.6%, 13.2%, 11.4%, 8.8%, 14.0% and 8.8%, respectively). Bruising was more common in the true acupuncture group (14.9%). LIMITATIONS, REASONS FOR CAUTION This study might have underestimated the sample size in the true acupuncture group with 4 months of treatment to enable detection of statistically significant changes in HOMA-IR with fixed acupuncture (i.e. a non-personalized protocol). Participants who withdrew because of pregnancy did not have further blood tests and this can introduce bias. WIDER IMPLICATIONS OF THE FINDINGS True acupuncture did not improve insulin sensitivity as effectively as metformin in women with PCOS and IR, but it is better than metformin in improving glucose metabolism (which might reduce the risk of type 2 diabetes) and has less side effects. Metformin had a higher incidence of gastrointestinal adverse effects than acupuncture groups, and thus acupuncture might be a non-pharmacological treatment with low risk for women with PCOS. Further studies are needed to evaluate the effect of acupuncture combined with metformin on insulin sensitivity in these women.

Abstract
Polycystic ovary syndrome (PCOS) is the main cause of female infertility worldwide and is associated with a substantially increased lifetime risk of comorbidities, including type 2 diabetes mellitus, psychiatric disorders and gynaecological cancers. Despite its high prevalence (~15%) and substantial economic burden, the aetiology of PCOS remains elusive. The genetic loci linked to PCOS so far account for only ~10% of its heritability, which is estimated at 70%. However, growing evidence suggests that altered epigenetic and developmental programming resulting from hormonal dysregulation of the maternal uterine environment contributes to the pathogenesis of PCOS. Male as well as female relatives of women with PCOS are also at an increased risk of developing PCOS-associated reproductive and metabolic disorders. Although PCOS phenotypes are highly heterogenous, hyperandrogenism is thought to be the principal driver of this condition. Current treatments for PCOS are suboptimal as they can only alleviate some of the symptoms; preventative and targeted treatments are sorely needed. This Review presents an overview of the current understanding of the aetiology of PCOS and focuses on the developmental origin and epigenetic inheritance of this syndrome.

Abstract
STUDY QUESTION Is there a shared genetic basis or causal relationship between polycystic ovary syndrome (PCOS) and a range of psychiatric disorders? SUMMARY ANSWER Genome-wide genetic correlation analysis and bidirectional Mendelian randomisation (MR) analysis suggest no shared genetic basis or causal relationship of PCOS with psychiatric disorders including depression, anxiety, schizophrenia and bipolar disorder. WHAT IS KNOWN ALREADY The comorbidity of PCOS with a range of psychiatric disorders has been recognised by epidemiological investigations yet a causal relationship remains unclear. Understanding of how genetic variations contribute to the susceptibility to PCOS and psychiatry disorders could provide meaningful insights into disease mechanisms. STUDY DESIGN, SIZE, DURATION We incorporated summary statistics from the hitherto largest genome-wide association studies (GWAS) conducted in subjects with PCOS (Ncase = 9322) or four common psychiatric disorders (depression, anxiety, schizophrenia and bipolar disorder) (Ncase ranges between 20 352 and 246 363), all of European ancestry. PARTICIPANTS/MATERIALS, SETTING, METHODS We quantified pairwise genetic correlation to understand the shared genetic predisposition using genome-wide genetic variants. We performed a two-sample bidirectional Mendelian randomisation analysis to make causal inferences, using GWAS-identified 102 depression-associated genetic instruments, 6 anxiety-associated instruments, 179 schizophrenia-associated instruments, 30 bipolar disorder-associated instruments and 14 PCOS-associated instruments. We performed several important sensitivity analyses examining sex hormones and utilising different MR approaches. MAIN RESULTS AND THE ROLE OF CHANCE We did not find significant genetic correlations (rg) for PCOS with psychiatric disorders (depression (rg = 0.09, P = 0.06), anxiety (rg = 0.15, P = 0.06), schizophrenia (rg = 0.02, P = 0.59), bipolar disorder (rg = 0.08, P = 0.19)). Genetic predisposition to PCOS was associated with depression in some of our MR approaches, without any evidence of pleiotropy (PMR-Egger intercept = 0.60). However, this weak PCOS-depression causal association attenuated to null after adjusting for BMI (1.00 (0.99-1.02), P = 0.28). On the contrary, we did not observe any statistically significant association between genetically instrumented PCOS with other psychiatric disorders (anxiety 1.01 (0.93-1.08), P = 0.89; schizophrenia 1.03 (0.97-1.10), P = 0.37; bipolar disorder 0.96 (0.90-1.03), P = 0.26). Bidirectional MR did not reveal an effect by which mental health conditions influenced PCOS risk. LIMITATIONS, REASONS FOR CAUTION Despite our study being the largest in sample size of its kind, the overall negligible causal relationship between PCOS and psychiatric outcomes may reflect a true null association but may also be due to a true effect too modest to be detected. We were not able to investigate PCOS subtypes and used an overall heterogenous PCOS sample due to limited availability of data. WIDER IMPLICATIONS OF THE FINDINGS Our comprehensive analysis does not identify a shared genetic basis of PCOS with psychiatric diseases. Although genetically instrumented PCOS appears to correlate with depression, such an effect is likely mediated by BMI, suggesting a role of non-genetic exposures underlying the observed comorbidity.

Abstract
Hyperandrogenism is the main characteristic of polycystic ovary syndrome, which affects placental function and fetal growth, and leads to reproductive and metabolic dysfunction in female offspring. Adiponectin acts on the placenta and may exert endocrine effects on the developing fetus. This study aims to investigate if maternal and/or fetal adiponectin can prevent metabolic and reproductive dysfunction in prenatal androgenized (PNA) female offspring. Adiponectin transgenic (APNtg) and wild-type dams received dihydrotestosterone/vehicle injections between gestational days 16.5-18.5 to induce PNA offspring, which were followed for 4 months. Offspring from APNtg dams were smaller than offspring from wild-type dams, independent of genotype. Insulin sensitivity was higher in wild-type mice from APNtg dams compared to wild-types from wild-type dams, and insulin sensitivity correlated with fat mass and adipocyte size. PNA increased visceral fat% and adipocyte size in wild-type offspring from wild-type dams, while wild-type and APNtg offspring from APNtg dams were protected against this effect. APNtg mice had smaller adipocytes than wild-types and this morphology was associated with an increased expression of genes regulating adipogenesis (Ppard, Pparg, Cebpa, and Cebpb) and metabolism (Chrebp and Lpl). Anogenital distance was increased in all PNA-exposed wild-type offspring, but there was no increase in PNA APNtg offspring, suggesting that adiponectin overexpression protects against this effect. In conclusion, elevated adiponectin levels in utero improve insulin sensitivity, reduce body weight and fat mass gain in the adult offspring and protect against PNA-induced visceral adiposity. In conclusion, these data suggest that PNA offspring benefit from prenatal adiponectin supplementation.

Abstract
A recent study by Mimouni et al. shows that late gestation exposure to anti-Müllerian hormone (AMH) results in transgenerational transmission of a polycystic ovary syndrome (PCOS)-like phenotype in mice. Altered DNA methylation underlies transmission and was also observed in women with PCOS. Epigenetics-based therapy reversed some PCOS-like phenotypic traits when applied to F3 female mice.

Abstract
Insulin resistance and lower muscle quality (strength divided by mass) are hallmarks of type 2 diabetes (T2D). Here, we explore whether alterations in muscle stem cells (myoblasts) from individuals with T2D contribute to these phenotypes. We identify VPS39 as an important regulator of myoblast differentiation and muscle glucose uptake, and VPS39 is downregulated in myoblasts and myotubes from individuals with T2D. We discover a pathway connecting VPS39-deficiency in human myoblasts to impaired autophagy, abnormal epigenetic reprogramming, dysregulation of myogenic regulators, and perturbed differentiation. VPS39 knockdown in human myoblasts has profound effects on autophagic flux, insulin signaling, epigenetic enzymes, DNA methylation and expression of myogenic regulators, and gene sets related to the cell cycle, muscle structure and apoptosis. These data mimic what is observed in myoblasts from individuals with T2D. Furthermore, the muscle of Vps39+/- mice display reduced glucose uptake and altered expression of genes regulating autophagy, epigenetic programming, and myogenesis. Overall, VPS39-deficiency contributes to impaired muscle differentiation and reduced glucose uptake. VPS39 thereby offers a therapeutic target for T2D.

Abstract
OBJECTIVE Obesity is considered to be the strongest predictive factor for cardio-metabolic risk in women with polycystic ovary syndrome (PCOS). The aim of the study was to compare blood pressure (BP) in normal weight women with PCOS and controls matched for age and BMI. METHODS From a Nordic cross-sectional base of 2615 individuals of Nordic ethnicity, we studied a sub cohort of 793 normal weight women with BMI < 25 kg/m2 (512 women with PCOS according to Rotterdam criteria and 281 age and BMI-matched controls). Participants underwent measurement of BP and body composition (BMI, waist-hip ratio), lipid status, and fasting BG. Data were presented as median (quartiles). RESULTS The median age for women with PCOS were 28 (25, 32) years and median BMI was 22.2 (20.7, 23.4) kg/m2. Systolic BP was 118 (109, 128) mmHg in women with PCOS compared to 110 (105, 120) mmHg in controls and diastolic BP was 74 (67, 81) vs 70 (64, 75) mmHg, both P < 0.001. The prevalence of women with BP ≥ 140/90 mmHg was 11.1% (57/512) in women with PCOS vs 1.8% (5/281) in controls, P < 0.001. In women ≥ 35 years the prevalence of BP ≥ 140/90 mmHg was comparable in women with PCOS and controls (12.7% vs 9.8%, P = 0.6). Using multiple regression analyses, the strongest association with BP was found for age, waist circumference, and total cholesterol in women with PCOS. CONCLUSIONS Normal weight women with PCOS have higher BP than controls. BP and metabolic screening are relevant also in young normal weight women with PCOS.

Abstract
If and how obesity and elevated androgens in women with polycystic ovary syndrome (PCOS) affect their offspring's psychiatric health is unclear. Using data from Swedish population health registers, we showed that daughters of mothers with PCOS have a 78% increased risk of being diagnosed with anxiety disorders. We next generated a PCOS-like mouse (F0) model induced by androgen exposure during late gestation, with or without diet-induced maternal obesity, and showed that the first generation (F1) female offspring develop anxiety-like behavior, which is transgenerationally transmitted through the female germline into the third generation of female offspring (F3) in the androgenized lineage. In contrast, following the male germline, F3 male offspring (mF3) displayed anxiety-like behavior in the androgenized and the obese lineages. Using a targeted approach to search for molecular targets within the amygdala, we identified five differentially expressed genes involved in anxiety-like behavior in F3 females in the androgenized lineage and eight genes in the obese lineage. In mF3 male offspring, three genes were dysregulated in the obese lineage but none in the androgenized lineage. Finally, we performed in vitro fertilization (IVF) using a PCOS mouse model of continuous androgen exposure. We showed that the IVF generated F1 and F2 offspring in the female germline did not develop anxiety-like behavior, while the F2 male offspring (mF2) in the male germline did. Our findings provide evidence that elevated maternal androgens in PCOS and maternal obesity may underlie the risk of a transgenerational transmission of anxiety disorders in children of women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder affecting up to 15% of women at reproductive age. The main features of PCOS are hyperandrogenism and irregular menstrual cycles together with metabolic dysfunctions including hyperinsulinemia and insulin resistance and a 4-fold increased risk of developing type 2 diabetes. Despite the high prevalence the pathophysiology of the syndrome is unclear. Insulin resistance in women with PCOS likely affect the skeletal muscle and recently it was demonstrated that changes in DNA methylation affects the gene expression in skeletal muscle that in part can explain their metabolic abnormalities. The objective of this work was to combine gene expression array data from different datasets to improve statistical power and thereby identify novel biomarkers that can be further explored. In this narrative review, we performed a meta-analysis of skeletal muscle arrays available from Gene Expression Omnibus and from publications. The eligibility criteria were published articles in English, and baseline (no treatment) skeletal muscle samples from women with PCOS and controls. The R package Metafor was used for integration of the datasets. One hundred and fourteen unique transcripts were differentially expressed in skeletal muscle from women with PCOS vs. controls (q < 0.05), 87% of these transcripts have not been previously identified as altered in PCOS muscle. ING2, CDKAL1, and AKTIP had the largest differential increase in expression, and TSHZ2, FKBP2, and OCEL1 had the largest decrease in expression. Two genes, IRX3 and CDKAL1 were consistently upregulated (q < 0.05) in the individual analyses and meta-analysis. Based on the meta-analysis, we identified several dysregulated immunometabolic pathways as a part of the molecular mechanisms of insulin resistance in the skeletal muscle of women with PCOS. The transcriptomic data need to be verified by functional analyses as well as proteomics to advance our understanding of PCOS specific insulin resistance in skeletal muscle.

Abstract
Nerve growth factor (NGF) is critical for the development and maintenance of the peripheral sympathetic neurons. NGF is also involved in the ovarian sympathetic innervation and in the development and maintenance of folliculogenesis. Women with the endocrine disorder, polycystic ovary syndrome (PCOS), have an increased sympathetic nerve activity and increased ovarian NGF levels. The role of ovarian NGF excess in the PCOS pathophysiology and in the PCOS-related features is unclear. Here, using transgenic mice overexpressesing NGF in the ovarian theca cells (17NF mice), we assessed the female embryonic development, and the reproductive and metabolic profile in adult females. Ovarian NGF excess caused growth restriction in the female fetuses, and a delayed gonocyte and primary oocyte maturation. In adulthood, the 17NF mice displayed irregular estrous cycles and altered ovarian expression of steroidogenic and epigenetic markers. They also exhibited an increased sympathetic output with increased circulating dopamine, and metabolic dysfunction reflected by aberrant adipose tissue morphology and function, impaired glucose metabolism, decreased energy expenditure, and hepatic steatosis. These findings indicate that ovarian NGF excess leads to adverse fetal development and to reproductive and metabolic complications in adulthood, mirroring common features of PCOS. This work provides evidence that NGF excess may be implicated in the PCOS pathophysiology.

Abstract
More than 1 out of 10 women worldwide are diagnosed with polycystic ovary syndrome (PCOS), the leading cause of female reproductive and metabolic dysfunction. Despite its high prevalence, PCOS and its accompanying morbidities are likely underdiagnosed, averaging > 2 years and 3 physicians before women are diagnosed. Although it has been intensively researched, the underlying cause(s) of PCOS have yet to be defined. In order to understand PCOS pathophysiology, its developmental origins, and how to predict and prevent PCOS onset, there is an urgent need for safe and effective markers and treatments. In this review, we detail which animal models are more suitable for contributing to our understanding of the etiology and pathophysiology of PCOS. We summarize and highlight advantages and limitations of hormonal or genetic manipulation of animal models, as well as of naturally occurring PCOS-like females.

Abstract
CONTEXT Autonomic nervous system activation mediates the increase in whole-body glucose uptake in response to electroacupuncture but the mechanisms are largely unknown. OBJECTIVE To identify the molecular mechanisms underlying electroacupuncture-induced glucose uptake in skeletal muscle in insulin-resistant overweight/obese women with and without polycystic ovary syndrome (PCOS). DESIGN/PARTICIPANTS In a case-control study, skeletal muscle biopsies were collected from 15 women with PCOS and 14 controls before and after electroacupuncture. Gene expression and methylation was analyzed using Illumina BeadChips arrays. RESULTS A single bout of electroacupuncture restores metabolic and transcriptional alterations and induces epigenetic changes in skeletal muscle. Transcriptomic analysis revealed 180 unique genes (q < 0.05) whose expression was changed by electroacupuncture, with 95% of the changes towards a healthier phenotype. We identified DNA methylation changes at 304 unique sites (q < 0.20), and these changes correlated with altered expression of 101 genes (P < 0.05). Among the 50 most upregulated genes in response to electroacupuncture, 38% were also upregulated in response to exercise. We identified a subset of genes that were selectively altered by electroacupuncture in women with PCOS. For example, MSX1 and SRNX1 were decreased in muscle tissue of women with PCOS and were increased by electroacupuncture and exercise. siRNA-mediated silencing of these 2 genes in cultured myotubes decreased glycogen synthesis, supporting a role for these genes in glucose homeostasis. CONCLUSION Our findings provide evidence that electroacupuncture normalizes gene expression in skeletal muscle in a manner similar to acute exercise. Electroacupuncture might therefore be a useful way of assisting those who have difficulties performing exercise.

Abstract
Nerve growth factor is a member of the neurotrophin family and within the ovary, it plays an important role in sympathetic innervation and in the development and maintenance of folliculogenesis. Despite its critical role, excessive levels of ovarian NGF may lead to ovarian pathology and to the development of features of polycystic ovary syndrome (PCOS), which is the most common endocrine disorder among women of reproductive age. Here, using a transgenic mouse model overexpressing NGF selectively in the ovary (17NF mice), we studied how ovarian sympathetic hyperactivity affects embryonic development and reproductive and metabolic function in adulthood. Firstly, we showed that ovarian NGF excess caused growth restriction in the developing female fetuses, which was driven by defects in the placenta function. Moreover, the 17NF fetuses experienced a reduction of germ cell number along with delayed gonocyte and primary oocyte maturation. The adult 17NF mice displayed irregular cyclicity and aberrant ovarian expression of steroidogenic genes and epigenetic markers. The ovarian sympathetic hyperactivity also led to increased systemic sympathetic outflow, indicated by increased circulating dopamine levels, and to metabolic dysfunction in adulthood. The 17NF mice had increased adiposity, impaired glucose metabolism and decreased energy expenditure. The subcutaneous and parametrial fat depots displayed impaired function due to ovarian NGF excess, wherein the subcutaneous fat increased mass by enhanced preadipocyte differentiation and enlarged adipocyte size, while the parametrial fat had smaller adipocyte size and a modest increase in stimulated lipolysis. These defects also led to hepatic steatosis. Overall, our findings indicate that ovarian sympathetic hyperactivity has deleterious effects on whole-body homeostasis and leads to impaired embryonic development and to reproductive and metabolic defects in adult life.

Abstract
More than 10% of women worldwide are diagnosed with polycystic ovary syndrome (PCOS), causing reproductive and metabolic disease. Hyperandrogenism is the main characteristic and elevated levels of androgens during pregnancy affect placenta function and fetal programming, which leads to reproductive and metabolic dysfunction in the offspring. Adiponectin secreted from adipose tissue improves whole-body metabolism, but its role during pregnancy is under explored. Adiponectin affects placental nutrient transport during pregnancy allowing for speculation that adiponectin can exert endocrine effects on the developing fetus. This study aims to investigate if, in prenatally androgenized (PNA) mice, adiponectin can prevent metabolic and reproductive dysfunction in female offspring. Adiponectin transgenic (APNtg) and wildtype (wt) female mice were mated with wt males, and received dihydrotestosterone or vehicle injections between gestational days 16.5-18.5 to induce a PCOS-like phenotype. The anogenital distance, a marker of in utero androgen exposure, was measured at 22 days of age, estrus cyclicity was recorded at 6 weeks of age, and metabolic measures were performed at 4 months of age. APNtg dams gave birth to significantly smaller offspring, independent of genotype, than wt dams. PNA increased f-insulin in all groups but insulin sensitivity was higher in wt mice from APNtg dams compared to wt mice from wt dams. Insulin resistance correlated with subcutaneous and visceral fat mass. PNA increased visceral fat % and adipocyte size in wt offspring from wt dams while wt and APNtg offspring from APNtg dams were protected against this effect. Visceral adipose tissue gene expression was unaltered in PNA wt offspring, regardless of the dam’s genotype, while APNtg offspring, regardless of PNA, had increased expression of adipogenic genes. Anogenital distance was increased in all PNA wt offspring independent of the dam’s genotype. There was, however, no difference between APNtg-vehicle and APNtg-PNA mice, suggesting that adiponectin overexpression protects against this effect. PNA leads to disrupted estrous cycle and fewer ovulations, but this effect was less pronounced in PNA wt mice from APNtg dams. Our data suggests that elevated maternal adiponectin protects the offspring against PNA induced metabolic dysfunction, and to a lesser extent reproductive dysfunction.

Abstract
Daughters of women with polycystic ovary syndrome (PCOS) are more likely to be diagnosed with PCOS, including reproductive and metabolic dysfunctions. Our recent research has demonstrated that dihydrotestosterone (DHT) exposure during late pregnancy results in transgenerational transmission of PCOS susceptibility to female offspring. But it remains unclear whether the transmission of the PCOS-like phenotypes is induced by in utero environment or via germ cell reprogramming, and whether treatment by exercise or androgen receptor blocker, flutamide, can prevent disease transmission. To model PCOS condition, donor mice were implanted with a continuous releasing DHT or vehicle pellet at 4 weeks of age. A subset of DHT exposed F0 donors had either free access to running wheels or were implanted with a slow-releasing flutamide pellet. Mice were exposed with or without treatment for either 6 weeks before IVF or 10 weeks prior to phenotypic testing. Here we present the phenotype of the F0 donors and the result of IVF to generate first (F1) and second (F2) generation offspring. Donors weigh more already after 2 weeks of DHT exposure and had more fat mass with larger adipocyte size, impaired glucose tolerance, and heavier kidney after 10 weeks of androgenization, which was reversed by both flutamide and exercise intervention. Moreover, DHT exposure increased circulating androgens and donors were completely acyclic. Simultaneous treatment with flutamide reversed the elevated androstenedione, testosterone, and restored estrus cyclicity, indicating that androgen receptor blocker can reverse hyperandrogenemia and reproductive dysfunction, whereas exercise failed to improve these phenotypes. After 6 weeks of exposure or treatment, donor oocytes were superovulated for IVF. Fewer oocytes per donor were found in androgenized + flutamide lineage, but no significant difference was observed in oocyte to two-cell embryo conversion rate after fertilization among all groups. Although the number of live offspring at weaning was similar among all groups, a trend of more F1 male than female offspring was found in both androgenized and androgenized + exercise lineage. Similar results were obtained in the F1 females when generating F2 offspring by IVF, which androgenized + flutamide lineage showed fewer oocytes per donor upon superovulation and more F2 male than female offspring was obtained in androgenized lineage at weaning. We here show that the androgenized donors develop clear PCOS-like phenotypes and give rise to more male than female F1 and F2 offspring. While blocking androgen receptor reverses both metabolic and reproductive disturbance in the donor, it also shows a negative impact on the donor and F1 female oocyte maturation process, although number of offspring via IVF is not affected. Excercise, however, only reverses the metabolic phenotypes in the F0 donor mice with no impact on IVF outcome.

Abstract
OBJECTIVE To test the hypothesis that acupuncture improves insulin sensitivity in women with polycystic ovary syndrome (PCOS) and insulin resistance (IR). DESIGN Prospective pilot study. SETTING Guangzhou, China, 2014-2016. PARTICIPANTS Eighty women with PCOS aged 18-40 years with body mass index (BMI) above 18.5 kg/m2 and with homeostatic model assessment for insulin resistance (HOMA-IR) index ⩾2.14. INTERVENTIONS Subjects received acupuncture with combined manual and low-frequency electrical stimulation of the needles three times per week for 6 months. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was the change in HOMA-IR after 6 months of acupuncture relative to baseline. Secondary outcomes included changes after 6 months of acupuncture and at 3 months of follow-up (both relative to baseline) in oral glucose tolerance test (OGTT) parameters (glucose and insulin levels), anthropometric measurements, and circulating metabolic and endocrine variables. RESULTS HOMA-IR and fasting plasma glucose and insulin levels were significantly decreased after 6 months of acupuncture, and both HOMA-IR and fasting insulin remained significantly decreased at 3 months of follow-up. In a subgroup analysis of normal-weight and overweight/obese women, HOMA-IR was reduced after 6 months of acupuncture in both subgroups, but there was no significant difference between the two groups. CONCLUSIONS Acupuncture treatment in Chinese women with PCOS and IR was associated with an encouraging improvement in insulin sensitivity. Further randomized controlled studies are required to confirm the efficacy of acupuncture for this indication.

Abstract
Background Traditional Chinese medicine (TCM) usually involves syndrome differentiation and treatment. Acupuncture, one form of TCM, requires the selection of appropriate acupoints and needling techniques, but many clinical trials on acupuncture have used fixed acupuncture protocols without accounting for individual patient differences. We have designed a multicenter randomized controlled trial (RCT) to evaluate whether personalized or fixed acupuncture increases the likelihood of live births in infertile women with polycystic ovary syndrome (PCOS) compared with letrozole or placebo letrozole. We hypothesize that letrozole is more effective than personalized acupuncture, which in turn is more effective than fixed acupuncture, and that placebo letrozole is the least effective intervention. Moreover, we hypothesize that personalized acupuncture is more likely to reduce the miscarriage rate and the risk of pregnancy complications compared with letrozole. Methods/design The study is designed as an assessor-blinded RCT. A total of 1100 infertile women with PCOS will be recruited from 28 hospitals and randomly allocated to 4 groups: personalized acupuncture, fixed acupuncture, letrozole, or placebo letrozole. They will receive treatment for 16 weeks, and the primary outcome is live birth. Secondary outcomes include ovulation rate, conception rate, pregnancy rate, pregnancy loss rate, changes in hormonal and metabolic parameters, and changes in quality of life scores. Adverse events will be recorded throughout the trial. All statistical analyses will be performed using IBM SPSS Statistics version 21.0 software (IBM Corp., Armonk, NY, USA), and a P value < 0.05 will be considered statistically significant. Discussion This study will be the first multicenter RCT to compare the effect of personalized or fixed acupuncture with letrozole or placebo letrozole on live birth in infertile women with PCOS. The findings will inform whether personalized acupuncture therapy can be considered an alternative treatment to improve the live birth rate in infertile women with PCOS.

Abstract
OBJECTIVE To date, little is known about differences in the knowledge, diagnosis making and treatment strategies of health care providers regarding polycystic ovary syndrome (PCOS) across different disciplines in countries with similar health care systems. To inform guideline translation, we aimed to study physician reported awareness, diagnosis and management of PCOS and to explore differences between medical disciplines in the Nordic countries and Estonia. METHODS This cross-sectional survey was conducted among 382 endocrinologists and obstetrician-gynaecologists in the Nordic countries and Estonia in 2015-2016. Of the participating physicians, 43% resided in Finland, 18% in Denmark, 16% in Norway, 13% in Estonia, and 10% in Sweden or Iceland, and 75% were obstetrician-gynaecologists. Multivariable logistic regression models were run to identify health care provider characteristics for awareness, diagnosis and treatment of PCOS. RESULTS Clinical features, lifestyle management and comorbidity were commonly recognized in women with PCOS, while impairment in psychosocial wellbeing was not well acknowledged. Over two-thirds of the physicians used the Rotterdam diagnostic criteria for PCOS. Medical endocrinologists more often recommended lifestyle management (OR = 3.6, CI 1.6-8.1) or metformin (OR = 5.0, CI 2.5-10.2), but less frequently OCP (OR = 0.5, CI 0.2-0.9) for non-fertility concerns than general obstetrician-gynaecologists. The physicians aged <35 years were 2.2 times (95% CI 1.1-4.3) more likely than older physicians to recommend lifestyle management for patients with PCOS for fertility concerns. Physicians aged 46-55 years were less likely to recommend oral contraceptive pills (OCP) for patients with PCOS than physicians aged >56 (adjusted odds ratio (OR) = 0.4, 95% CI 0.2-0.8). CONCLUSION Despite well-organized healthcare, awareness, diagnosis and management of PCOS is suboptimal, especially in relation to psychosocial comorbidities, among physicians in the Nordic countries and Estonia. Physicians need more education on PCOS and evidence-based information on Rotterdam diagnostic criteria, psychosocial features and treatment of PCOS, with the recently published international PCOS guideline well needed and welcomed.

Abstract
OBJECTIVES Previous studies of women in their 20s and 30s have reported impaired autonomic function in women with polycystic ovary syndrome (PCOS). We aimed to study, for the first time, whether PCOS is associated with impaired cardiac autonomic function independent of metabolic and hormonal status in their late reproductive years. DESIGN A prospective Northern Finland Birth Cohort 1966 (NFBC1966) study including 5889 women born in 1966 and followed through the age of 46. At that age, n=3706/5123 women (72%) answered the postal questionnaires and n=3280/5123 women (64%) participated in the clinical examination. SETTING General community. PARTICIPANTS The sample included women presenting both irregular menses (oligomenorrhoea or amenorrhoea) and hirsutism at age 31 (n=125) or with formally diagnosed PCOS by age 46 (n=181) and women without PCOS symptoms or diagnosis (n=1577). PRIMARY AND SECONDARY OUTCOME MEASURES Heart rate variability parameters: the root mean square of successive R-R differences (rMSSD), spectral power densities (LF: low frequency and HF: high frequency) and baroreflex sensitivity (BRS). RESULTS We found that parasympathetic activity (assessed by rMSSD: 19.5 (12.4; 31.9) vs 24.3 (16.1; 34.8) ms, p=0.004 and HF: 172 (75; 399) vs 261 (112; 565) ms2, p=0.002) and BRS (6.13±3.12 vs 6.99±3.52 ms/mm Hg, p=0.036) were lower in women with PCOS compared with the controls. However, in the multivariate regression analysis, PCOS, body mass index and the free androgen index did not significantly associate with rMSSD, whereas blood pressure, insulin resistance and triglycerides did. CONCLUSIONS We report here for the first time that late reproductive-aged women with PCOS display impaired cardiac autonomic function manifested as decreased vagal activity. Metabolic status, rather than hyperandrogenaemia and PCOS per se, was the strongest contributing factor. Given the link between cardiac morbidity and impaired autonomic function, the findings underline the importance of screening and treating metabolic abnormalities early on in women with PCOS.

Abstract
Background Antenatal depression affects 10–20% of pregnant women. Around 2–4% of European pregnant women use antidepressant treatment, most commonly selective serotonin reuptake inhibitors (SSRIs). Poor pregnancy outcomes, such as preterm birth and low birth weight, have been described in women with antenatal depression and in pregnant women on SSRI treatment. However, the effects of antenatal depression and antidepressant treatment on the placenta are largely unknown. The aim of this work was to compare placental gene and protein expression in healthy women, women with untreated antenatal depression and women on antidepressant treatment during pregnancy. Methods Placental samples from 47 controls, 25 depressed and 45 SSRI-treated women were analysed by means of qPCR using custom-designed TaqMan low-density arrays (TLDAs) for 44 genes previously known to be involved in the pathophysiology of depression, and expressed in the placenta. Moreover, placental protein expression was determined by means of immunohistochemistry in 37 healthy controls, 13 women with untreated depression and 21 women on antidepressant treatment. Statistical comparisons between groups were performed by one-way ANOVA or the Kruskal–Wallis test. Results Nominally significant findings were noted for HTR1A and NPY2R, where women with untreated depression displayed higher gene expression than healthy controls (p < 0.05), whereas women on antidepressant treatment had similar expression as healthy controls. The protein expression analyses revealed higher expression of HTR1A in placentas from women on antidepressant treatment, than in placentas from healthy controls (p < 0.05). Conclusion The differentially expressed HTR1A, both at the gene and the protein level that was revealed in this study, suggests the involvement of HTR1A in the effect of antenatal depression on biological mechanisms in the placenta. More research is needed to elucidate the role of depression and antidepressant treatment on the placenta, and, further, the effect on the fetus.

Abstract
OBJECTIVE Existing data are contradictory on the prevalence of polycystic ovary syndrome (PCOS) and metabolic syndrome (MetS) in women with severe obesity (body mass index [BMI] ≥ 35 kg/m2 ), and there are few studies investigating the effect of weight reduction in women with severe obesity and PCOS. The aim was to study the prevalence of PCOS and MetS among women with severe obesity and to evaluate the effect of a 12-months weight loss programme on the prevalence of PCOS and MetS. DESIGN/PARTICIPANTS In total, 298 women with severe obesity were enrolled whereof 246 women had complete screening data for PCOS and MetS before commencing treatment. Weight loss intervention included very low energy diet. At 12-months follow-up, 72 women with complete data remained and were re-examined with baseline parameters. RESULTS At baseline, the prevalence of PCOS was 25.6% and in this group, the prevalence of MetS was 43.4% in PCOS vs 43.3% in controls (ns). At 12-months follow-up, weight loss in women with PCOS was 12.3 ± 10.7 kg (P < .001) and in non-PCOS 13.9 ± 13.4 kg (P < .001) with no between group difference. Women without PCOS decreased in total bone mass. CONCLUSIONS Polycystic ovary syndrome occurs in one out of four women with severe obesity. The prevalence of MetS does not differ between women with or without PCOS with severe obesity. There was a significant weight loss in both groups but no difference between groups regarding change in metabolic parameters.

Abstract
Abstract
Aims
Polycystic ovary syndrome (PCOS) is a common endocrinopathy that is suggested to increase the risk for cardiovascular disease. How PCOS may lead to adverse cardiac outcomes is unclear and here we hypothesized that prenatal exposure to dihydrotestosterone (DHT) and/or maternal obesity in mice induce adverse metabolic and cardiac programming in female offspring that resemble the reproductive features of the syndrome.
Methods and results
The maternal obese PCOS phenotype was induced in mice by chronic high-fat–high-sucrose consumption together with prenatal DHT exposure. The prenatally androgenized (PNA) female offspring displayed cardiac hypertrophy during adulthood, an outcome that was not accompanied by aberrant metabolic profile. The expression of key genes involved in cardiac hypertrophy was up-regulated in the PNA offspring, with limited or no impact of maternal obesity. Furthermore, the activity of NADPH oxidase, a major source of reactive oxygen species in the cardiovascular system, was down-regulated in the PNA offspring heart. We next explored for early transcriptional changes in the heart of newly born PNA offspring, which could account for the long-lasting changes observed in adulthood. Neonatal PNA hearts displayed an up-regulation of transcription factors involved in cardiac hypertrophic remodelling and of the calcium-handling gene, Slc8a2. Finally, to determine the specific role of androgens in cardiovascular function, female mice were continuously exposed to DHT from pre-puberty to adulthood, with or without the antiandrogen flutamide. Continuous exposure to DHT led to adverse left ventricular remodelling, and increased vasocontractile responses, while treatment with flutamide partly alleviated these effects.
Conclusion
Taken together, our results indicate that intrauterine androgen exposure programmes long-lasting heart remodelling in female mouse offspring that is linked to left ventricular hypertrophy and highlight the potential risk of developing cardiac dysfunction in daughters of mothers with PCOS.

Abstract
OBJECTIVE Serum levels of retinol-binding protein 4 (RBP4), an adipokine thought to affect systemic insulin sensitivity, were compared between women with polycystic ovary syndrome (PCOS) and non-PCOS controls to evaluate the association of RBP4 with clinical, hormonal and metabolic parameters of PCOS. SUBJECTS AND METHODS Serum RBP4 levels were analysed in 278 women with PCOS (age range 18-57 years) and 191 non-PCOS controls (age 20-53 years) by enzyme-linked immunosorbent assay. RESULTS Serum levels of RBP4 were increased in women with PCOS compared with control women in the whole population (45.1 ± 24.0 (s.d.) vs 33.5 ± 18.3 mg/L, P < 0.001). Age-stratified analysis showed that serum RBP4 levels were increased in women with PCOS aged ≤30 years compared with controls (47.7 ± 23.5 vs 27.1 ± 10.4 mg/L, P < 0.001), whereas no significant differences were seen in the other age groups. No significant correlations of RBP4 were seen with either steroids or indices of insulin resistance. CONCLUSIONS Although serum RBP4 levels were increased in younger women with PCOS compared with age-matched non-PCOS controls, RBP4 does not seem to be a good marker of insulin resistance or other metabolic derangements in women with PCOS.

Abstract
It is suggested that intrauterine environment play a role in the development of PCOS, and that first generation (F1) male offspring of the prenatal androgenized (PNA)-mice model exhibit metabolic dysfunction such as increased body weight and insulin resistance. Whether prenatal androgenisation, with or without diet-induced obesity, cause transgenerational effects on the male offspring through the paternal lineage have not previously been investigated. Therefore, we investigated how maternal high-fat high sucrose (HFHS) diet-induced obesity and in utero exposure to dihydrotestosterone (DHT) during embryonic day (E) 16.5-E18.5 (to create a PNA model) affect the metabolic phenotype of first, second and third (F1 to F3) generation male offspring. F1 and F2 male offspring were mated with females fed control diet (CD) to follow the paternal lineage. We found that F1 males born from mothers exposed to DHT and fed CD have longer anogenital distance (AGD), demonstrating androgen exposure in utero with no effect on F2 and F3 male offspring. F1 males from DHT exposed mothers with diet-induced obesity weigh more compared to F1 males from lean or obese mothers, with no differences in F2 and F3 male offspring. However, the F3 males from DHT exposed great-grand-mothers with diet-induced obesity have higher fat mass compared to other groups indicating a transgenerational effect. Moreover, F1 males from mothers with diet-induced obesity were insulin resistant with increased HOMA-IR and F3 male offspring from the same group exhibited impaired glucose tolerance as measured with oral glucose tolerance test. At night, when mice are more active, had F1 males from DHT exposed mothers fed CD or diet-induced obesity, and from vehicle treated mothers with diet-induced obesity, lower energy expenditure (EE) and respiratory exchange ratio (RER) measurement. Of note, the metabolic phenotype was exaggerated in F3 male offspring, with significantly lower EE, RER and total activity both during day and night time. These results likely reflect the higher body weight and increased fat mass in F1 and F3 male offspring. Taken together, these results demonstrate that diet-induced obesity before and during pregnancy together with androgen exposure cause a transgenerational effect on metabolic features in male offspring following the male germline.

Abstract
The fetal life is a critical window of developmental patterning affecting growth trajectories before birth and can influence the risk of reproductive and metabolic disease in adulthood. Maternal obesity and elevated prenatal androgens are two prominent potential exposures which may affect the development of the embryo and its postnatal life. If in utero androgen exposure with or without maternal obesity increase female offspring susceptibility for transgenerational inheritance of reproductive and metabolic disease has not been investigated. Therefore we fed female mice high-fat high sucrose (HFHS) or control diet (CD) diet for 6 weeks prior mating to induce obesity and exposed pregnant female mice to prenatal androgen exposure with dihydrotestosterone (DHT) or vehicle during the embryonic day (E) 16.5-E18.5. At weaning, first, second and third generation (F1, F2, and F3) female offspring from DHT exposed mothers with diet-induced obesity had longer anogenital distance (AGD), a marker of in utero androgen exposure, and disturbed estrous cycle compared with offspring from vehicle treated mothers fed CD. F1 and F3 female offspring from DHT exposed mothers and great-grand mothers with diet-induced obesity weighed more compared to offspring from vehicle-treated obese mothers, and F3 female offspring from great-grand DHT exposed mothers had more fat mass assessed by EchoMRI. Additionally, F1 and F3 female offspring from DHT exposed mothers and great-grand mothers with or without diet-induced obesity displayed a lower respiration exchange ratio and reduced energy expenditure than offspring from vehicle-treated mothers fed CD assessed by the metabolic cages. Finally, mice were superovulated to collect MII oocytes for single-cell RNA sequencing. Our preliminary analysis reveal that genes related to preimplantation embryonic imprinting are differentially expressed in F1, F2, and F3 female offspring from DHT exposed mothers, grandmothers, and great-grandmothers fed CD, and in mice from mothers with diet-induced obesity. These results demonstrate that in utero androgen exposure and diet-induced obesity contribute to transgenerational effects on reproductive and metabolic phenotypes in adult female offspring, involving altered expression of preimplantation imprinting genes in germ cells.

Abstract
Abstract: Obese women who develop gestational diabetes show lower adiponectin levels across pregnancy than obese euglycaemic women suggesting that obese women with low adiponectin levels have an impaired capacity to handle the metabolic changes during pregnancy. Adiponectin acts on the placenta during pregnancy; this fact allows for the interesting possibility that adiponectin can exert endocrine effects on the developing fetus. The aim here was to investigate how adiponectin affects cellular and molecular mechanisms regulating fetal growth and metabolic functions during pregnancy. Wild type (wt) and adiponectin transgenic (APNtg) mice were fed normal chow or a high fat/high sucrose (HF/HS) diet for 8 weeks before mating with wt males. Fetus were dissected on pregnancy day 18.5. Maternal adiponectin overexpression decreased fetal body weight in dams on normal chow, and even more in dams on HF/HS diet. There was no difference in fasting glucose between the groups on normal chow and HF/HS diet, but APNtg animals had lower fasting glucose levels compared to wt. We also investigated the role of adiponectin on lipid uptake. Wild type dams fed HF/HS diet had decreased levels of circulating triglycerides but increased levels of liver triglycerides. However, APNtg dams were partly protected against the development of fatty liver confirming previous studies. In contrast, liver triglyceride levels were increased in fetuses from APNtg dams on HF/HS diet, suggesting an increased transport of lipids to the developing fetuses. To further investigate placenta function, we measured the expression of genes involved in placental nutrient transport. We found an increased expression of lipoprotein lipase (LPL), while IRS-1 expression was decreased in placentas from APNtg fetuses regardless of the dam’s genotype or diet. Adiponectin has previously been shown to decrease nutrient transport across placenta, with the assumption that the main nutrient transport is glucose. Our data opens up for the possibility that adiponectin may increases lipid delivery to the fetus.

Abstract
Polycystic ovary syndrome (PCOS) is suggested to increase the risk for cardiovascular disease and type 2 diabetes. We hypothesized here that prenatal exposure to dihydrotestosterone (DHT) and/or maternal obesity lead to adverse metabolic and cardiac programming in the female offspring. The maternal obese PCOS phenotype was induced in mice by prenatal DHT exposure (PNA) combined with high-fat/high-sucrose (HFHS) diet. The female offspring were subjected to metabolic and cardiac assessment during adulthood. The PNA offspring displayed cardiac hypertrophy, as indicated by increased interventricular septal and posterior wall thickness on echocardiography. These observations were not accompanied by aberrant metabolic profile. The expression of targeted genes involved in cardiac hypertrophy, fibrosis, and calcium signaling was upregulated in PNA female offspring, with limited or no impact of maternal obesity. Furthermore, we examined whether the maternal obese PCOS phenotype augmented NADPH oxidase (NOX)-derived ROS production, as a contributing source of oxidative stress. Paradoxically, NOX activity was decreased and associated with upregulated gene expression of antioxidant enzymes in the PNA offspring heart. Next, we explored for early signs of alterations in the heart of newly born PNA offspring, which could account for the long-lasting changes observed in adulthood. Neonatal PNA hearts displayed an upregulation of transcription factors involved in cardiac hypertrophic remodeling and of genes related to calcium signaling. To determine the specific role of androgens in cardiovascular function, prepubertal female mice were implanted a pellet containing DHT or vehicle and were subjected to metabolic and cardiac assessment during adulthood. Continuous exposure to DHT led to adverse left ventricular remodeling, including increased left ventricular mass and dysregulated gene expression profile. Lastly, myography studies of mesenteric arteries revealed increased vasocontractile responses in the DHT- exposed females, suggestive of hypertension. Taken together, early life exposure to androgens may program an adverse cardiovascular phenotype in female offspring, which is most likely linked to hyperandrogenism.

Abstract
OBJECTIVE Many complex diseases exhibit co-morbidities often requiring management by more than one health specialist. We examined cross-speciality issues that ultimately affect the health and wellbeing of patients with polycystic ovary syndrome (PCOS). PCOS was originally described as a reproductive condition but is now recognised to also be a metabolic and psychological condition affecting 8-13% of women of reproductive age. With a four-fold increased risk of type 2 diabetes (DM2), the Population Attributable Risk of DM2 that could be avoided if PCOS were eliminated is a substantial 19-28% of women of reproductive age. To determine the extent to which PCOS is an important consideration in diabetes development, we examined publications, funding, guidelines and predictors of risk of developing DM2. RESULTS We found that the topic of PCOS appeared in specialist diabetes journals at only 10% the rate seen in endocrinology journals - about 1 in 500 articles. We found research funding to be substantially less than for diabetes and found that diabetes guidelines and predictive tools for DM2 risk mostly ignore PCOS. This is surprising since insulin resistance in women with PCOS has a different aetiology and additionally women with PCOS are at increased risk of becoming overweight or obese - high risk factors for DM2. CONCLUSIONS We consider the causes of these concerning anomalies and discuss current activities to address the co-morbidities of PCOS, including the recent development of international guidelines, an international PCOS awareness program and potentially changing the name of PCOS to better reflect its metabolic consequences.

Abstract
BACKGROUND/OBJECTIVES Maternal obesity together with androgen excess in mice negatively affects placental function and maternal and fetal liver function as demonstrated by increased triglyceride content with dysfunctional expression of enzymes and transcription factors involved in de novo lipogenesis and fat storage. To identify changes in molecular pathways that might promote diseases in adulthood, we performed a global proteomic analysis using a liquid-chromatography/mass-spectrometry system to investigate total and phosphorylated proteins in the placenta and fetal liver in a mouse model that combines maternal obesity with maternal androgen excess. METHODS After ten weeks on a control diet (CD) or high fat/high sugar-diet, dams were mated with males fed the CD. Between gestational day (GD) 16.5 and GD 18.5, mice were injected with vehicle or dihydrotestosterone (DHT) and sacrificed at GD 18.5 prior to dissection of the placentas and fetal livers. Four pools of female placentas and fetal livers were subjected to a global proteomic analysis. Total and phosphorylated proteins were filtered by ANOVA q < 0.05, and this was followed by two-way ANOVA to determine the effect of maternal obesity and/or androgen exposure. RESULTS In placenta, phosphorylated ATP-citrate synthase was decreased due to maternal obesity, and phosphorylated catechol-O-methyltransferase (COMT) was differentially expressed due to the interaction between maternal diet and DHT exposure. In fetal liver, five total proteins and 48 proteins phosphorylated in one or more sites, were differentially expressed due to maternal obesity or androgen excess. In fetal liver, phosphorylated COMT expression was higher in fetus exposed to maternal obesity. CONCLUSION These results suggest a common regulatory mechanism of catecholamine metabolism in the placenta and the fetal liver as demonstrated by higher phosphorylated COMT expression in the placenta and fetal liver from animals exposed to diet-induced maternal obesity and lower expression of phosphorylated COMT in animals exposed to maternal androgen excess.

Abstract
RESEARCH QUESTION What is the association between hyperhomocysteinaemia (HHCY), metabolic syndrome, and reproductive outcomes among women with polycystic ovary syndrome (PCOS). DESIGN A secondary analysis of PCOSAct with 21 sites in China. A total of 1000 women with PCOS were enrolled; 936 women with baseline homocysteine (HCY) were analysed. RESULTS Higher HCY was associated with higher body mass index, free testosterone and lower FSH, fasting glucose (P < 0.001; P < 0.001; P = 0.005; P < 0.001) and ovulation rate among all participants (OR 0.59, 95% CI 0.41 to 0.86; OR 0.57, 95% CI 0.39 to 0.83 tertiles 2 and 3 versus tertile 1, respectively). The HHCY group had lower oestradiol and higher free testosterone (P = 0.04; P < 0.001) than the controls. In the metabolic syndrome group, LH, LH-FSH ratio and sex hormone-binding globulin were lowest in the metabolic syndrome group (all P < 0.001). In the HHCY group, ovulation rate decreased and the second or third trimester pregnancy loss rate increased compared with controls (OR 1.678, 95% CI 1.04 to 2.70; OR 0.03, 95% CI 0.00 to 0.42) with treatment adjustment. Compared with the controls, ovulation, conception, pregnancy, second or third trimester pregnancy loss and live birth rates were statistically lower in the metabolic syndrome group after adjusting treatment (OR 1.76, 95% CI 1.15 to 2.70; OR 1.75, 95% CI 1.15 to 2.65; OR 2.09, 95% CI 1.27 to 3.44; OR 0.02, 95% CI 0.00 to 0.33; OR 2.42 95% CI 1.42 to 4.10), and pregnancy, pregnancy loss and live birth rates remained significantly different after adjusting for treatment and sex-hormone factors (OR 1.77, 95% CI 1.05 to 2.99; OR 0.14, 95% CI 0.02 to 0.82; OR 2.02, 95% CI 1.16 to 3.50). CONCLUSIONS In women with PCOS, HHCY contributes to increased pregnancy loss and reduced ovulation, and metabolic syndrome was related to defects in ovulation, conception, pregnancy, pregnancy loss and live birth, indicating that the two conditions lead to defects at various reproductive stages.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is linked to hyperinsulinemia and insulin resistance with dysfunctional glucose metabolism. Pilot studies suggests that acupuncture treatment with combined manual and low-frequency electrical stimulation (electroacupuncture (EA)) of the needles decrease circulating glycated haemoglobulin (HbA1c) and homeostatic model assessment-insulin resistance. Therefore, we here aim to investigate if acupuncture treatment or metformin together with lifestyle or lifestyle management alone improves insulin sensitivity and related symptoms in overweight/obese women with PCOS. METHODS AND ANALYSIS This is a two-centre multinational (Sweden and China), cross-sectional case-control study combined with an open-labelled randomised controlled trial (RCT). Participants are randomised to one of three groups: (1) EA 2-3 times/week during 4 months+lifestyle management; (2) metformin, 500 mg, three/day during 4 months+lifestyle management; or (3) lifestyle management alone. The primary outcome measure in the RCT is changes in HbA1C. A total of 123 obese overweight women with PCOS will be enrolled and randomised into one of the three groups with a target power of at least 80% and 5% significance level based on two-sided tests. ETHICS AND DISSEMINATION The study has been approved by the Regional Ethical Review Board of Stockholm and of Peking University Third Hospital, China. Primary outcome data of the RCT will be published in a relevant journal together with supporting secondary outcome measurements. Further, outcome measurements will be published in separate papers as well as case-control data. EXPECTED RESULTS We anticipate that EA and metformin, both with lifestyle management, are equally effective and superior to lifestyle management alone for improvement of glycaemic control. TRIAL REGISTRATION NUMBERS NCT02647827 and EudraCT2015-004250-18.

Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder of unclear etiology in women and is characterized by androgen excess, insulin resistance, and mood disorders. The gut microbiome is known to influence conditions closely related with PCOS, and several recent studies have observed changes in the stool microbiome of women with PCOS. The mechanism by which the gut microbiome interacts with PCOS is still unknown. We used a mouse model to investigate if diet-induced maternal obesity and maternal DHT exposure, mimicking the lean and obese PCOS women, cause lasting changes in the gut microbiome of offspring. Fecal microbiome profiles were assessed using Illumina paired-end sequencing of 16S rRNA gene V4 amplicons. We found sex-specific effects of maternal and offspring diet, and maternal DHT exposure on fecal bacterial richness and taxonomic composition. Female offspring exposed to maternal obesity and DHT displayed reproductive dysfunction and anxietylike behavior. Fecal microbiota transplantation from DHT and diet-induced obesity exposed female offspring to wild-type mice did not transfer reproductive dysfunction and did not cause the expected increase in anxietylike behavior in recipients. Maternal obesity and androgen exposure affect the gut microbiome of offspring, but the disrupted estrous cycles and anxietylike behavior are likely not microbiome-mediated.
