Role of the Ketogenic Diet in Women With PCOS
Polycystic Ovary SyndromeFor the fact of PCOS symptoms could be improved with weight loss and improving insulin resistance, the investigators will do this study to evaluate the role of the ketogenic diet in overweight and obese women with PCOS.
The RolE oF Androgen Excess in MUscle Energy MetaboLism in Women With PolyCystic Ovary Syndrome...
Polycystic Ovary SyndromeAndrogen Excess1 morePolycystic ovary syndrome (PCOS) affects 10% of all women, and it usually co-exists with high levels of sex hormones called androgens, such as testosterone. Women with PCOS are at increased risk of metabolic complications such as diabetes, non-alcoholic fatty liver disease, high blood pressure and heart disease. However, very little is understood about how androgen excess may drive the metabolic complications observed in women with PCOS. Skeletal muscle is an important site of energy metabolism; increasingly, it is suspected that skeletal muscle energy balance is adversely impacted by androgens, thereby driving metabolic complications. To take this theory forward, we want to investigate the effects of androgens on muscle energy metabolism. We will perform detailed metabolic testing (including blood tests and muscle biopsies) in women with PCOS before and after taking tablets that block the action of testosterone for 28 days. In addition, we will be using a gold standard technique to see how women with PCOS metabolise fat and other nutrients by measuring markers in blood and breath samples after a breakfast test meal. This clinical research will increase our understanding of the complex relationships between hormonal abnormalities and metabolic disease in women with PCOS.
Ultrasound Characterization of Ovarian Follicle Dynamics in Women With Amenorrhea
OligomenorrheaAmenorrhea1 moreIn women with regular menstrual cycles, antral follicles have been shown to grow in synchronous cohorts, called waves, 2-3 times in a menstrual cycle. It is unknown whether these waves of follicle growth also occur in women with amenorrhea or if there is abnormal/absent follicle growth. Further, oligo- or amenorrhea has been associated with metabolic disturbances, such as over- or under-nutrition, central obesity and insulin resistance. Yet, mechanisms whereby metabolic factors influence folliculogenesis in women are poorly understood. To understand potential mechanisms, the investigators plan to characterize follicle growth dynamics in women with or without regular menstrual cycles and identifying key metabolic differences in these women which may be important in normal follicle development and fertility.

A Cooking and Eating Study
Polycystic Ovary SyndromeBackground. The polycystic ovary syndrome (PCOS) is a complex hormonal disorder that presents in susceptible girls around the time of menarche. Females with PCOS have high levels of androgens (e.g., testosterone). While cosmetic appearance (excess facial hair and acne) and menstrual disturbances were once considered the primary concerns, emerging data indicate that many adolescents and young adults with PCOS are insulin resistant and at increased risk for metabolic syndrome and diabetes. The majority of females with PCOS are obese, and excess body fat amplifies the severity of the syndrome. Dietary intervention is considered an important component of treatment for PCOS. However, a consensus statement regarding optimal nutrient composition for treating adolescents and young adults with PCOS has not been published because data are lacking to provide a foundation for such a statement. Recognizing increased risk for diabetes in patients with PCOS, many practitioners employ a low-fat diet as prescribed in the Diabetes Prevention Program (DPP) for weight loss and control of symptoms. Objective and Hypothesis. The purpose of this research study is to compare different diets for treating PCOS. We hypothesize that a low-glycemic load diet - designed to lower blood levels of glucose and insulin - will be more beneficial than a low-fat diet in obese adolescents and young adults with PCOS. Design. We propose a 6-month study in which 50 obese females with PCOS (ages 13 to 21 years) will be assigned to receive one of two dietary treatments, with the goal of retaining 40 participants. Group assignment will be at random. One of the treatments will be a low-glycemic load diet, and the other treatment will be a low-fat diet (modeled after the DPP diet). Participants in both groups will receive individual nutrition education and dietary counseling with a registered dietitian (clinic visits, telephone calls) and cooking workshops with a chef. The purpose of the cooking workshops will be to enhance compliance with diet prescriptions, beyond what can be achieved by nutrition education and dietary counseling in a conventional clinic setting. The primary outcome will be bioavailable testosterone (form of testosterone that causes symptoms of PCOS). Secondary outcomes will include other blood tests to evaluate further high androgen levels (total testosterone, free testosterone, sex hormone binding globulin, dehydroepiandrosterone sulfate), clinical signs of high androgen levels (excess facial hair, acne), glucose tolerance and risk for diabetes (determined by blood sugar and insulin measurements), risk for cardiovascular disease (based on blood cholesterol and C-reactive protein levels and blood pressure), body fat percentage and distribution (measured using state-of-the-art dual energy x-ray absorptiometry and waist circumference), menstrual cyclicity, and health-related quality of life (evaluated by questionnaire).
Metformin in Assisted Reproduction-MET-AR-study
Polycystic Ovary SyndromeAim of study: To investigate whether four months of metformin treatment before IVF (in-vitro-fertilisation) or ICSI (intra-cytoplasmic-sperm-injection) might increase clinical pregnancy rate in normal-weight (body mass index [BMI] below 28 kg/m3) in PCOS (polycystic ovarian syndrome) women.
Metformin, Vitamin D, and Depression in Polycystic Ovary Syndrome (PCOS) Trial
PCOSDepression2 moreOpen-label randomized clinical trial assessing the efficacy of Metformin versus Vitamin D in improving symptoms of depressed mood in polycystic ovary syndrome.
MLE4901 vs. Placebo for the Treatment of PCOS

Determination of the Incidence of Endometriosis and or Adenomyosis in Patients Diagnosed With Polycystic...
EndometriosisPolycystic Ovary Syndrome1 moreThe study was designed as a multicenter, prospective cross-sectional cohort study. The research population will consist of patients under the age of 40, diagnosed with endometriosis and/or adenomyosis and polycystic ovary syndrome, who applied to the obstetrics and gynecology outpatient clinics in 13 centers. According to the results of the sample size analysis, it was planned to terminate the study when 1225 patients with polycystic ovary syndrome and 1225 patients with endometriosis and/or adenomyosis were recruited.
Polycystic Ovary Syndrome (PCOS) and Sleep Apnea
Polycystic Ovary SyndromeObstructive Sleep ApneaPolycystic ovary syndrome (PCOS) affects 5-10% of women in the United States. Its onset is usually at the time of puberty with manifestations of menstrual irregularity, hirsutism, and obesity. Women with PCOS suffer at an early stage of adulthood from all of the components of the metabolic syndrome, a syndrome that typically has its peak in mid-life in other subject populations. Women with PCOS are more insulin resistant than weight-matched control women and have exceptionally high rates of early-onset impaired glucose tolerance and type 2 diabetes, as well as a substantially elevated risk for hypertension, dyslipidemia, coronary, and other vascular diseases. While recent evidence indicates that the prevalence of sleep-disordered breathing (SDB) is 30-40 fold higher in PCOS than in weight-matched control women, the possible role of SDB in causing the increased metabolic and cardiovascular risks of PCOS has not been evaluated. The overall objective of the proposed study is to analyze the direction of causality between sleep disturbances and markers of the metabolic syndrome in PCOS.
