Filter by:In 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.
The purpose of this study is to help determine the best treatment plan for women with PCOS who are overweight or obese and experiencing significant symptoms of depression and anxiety. Specifically, the investigators are attempting to see if there is a difference between cognitive behavioral therapy in combination with nutritional counseling in improving mood symptoms, response to stress, and risk factors for heart disease compared to nutrition counseling alone. The investigators hypothesize that combined treatment with Cognitive Behavioral Therapy (CBT) and nutritional counseling will be more beneficial.
The purpose of this research study is to collect specimen samples and study medical information from women with Polycystic Ovary Syndrome (PCOS) and women without PCOS. The goal is to learn more about the changes that take place in the body that result in PCOS. We anticipate that 32 women will take part in this study (16 without PCOS and 16 with PCOS). All patients will undergo a physical exam, blood tests, and ultrasound of their ovaries. If they meet the criteria for this study, they will then undergo additional blood tests, removal of a small amount of subcutaneous abdominal fat, measurement of regional body fat (i.e., DXA scan) and a modified frequently-sampled intravenous glucose tolerance test (FSIGTT). The women without PCOS will complete the study at this point. The women with PCOS will be randomized to receive the drug flutamide 125 mg/day or placebo. They will take the drug every day for six 28-day cycles. They will be asked to collect and store a urine sample once a week. They will also be asked to complete a pill diary and menstrual diary. Once a month while they are taking the flutamide/placebo, they will return to the clinic and bring their frozen urine samples. At that time they will undergo a physical exam, toxicity assessment, and blood draw. Quality of Life assessments will be done at the beginning of the study for all participants. Women with PCOS who are taking the flutamide or placebo will be asked to repeat the Quality of Life assessments during the study and at the end of the study. After the six 28-day cycles are completed they will then undergo additional blood tests, removal of a small amount of subcutaneous abdominal fat, measurement of regional body fat (i.e., DXA scan) and a modified frequently-sampled intravenous glucose tolerance test (FSIGTT). Six months following the completion of all study protocol procedures, participants who received flutamide/placebo will be contacted by phone to check on the status of their health. They will be asked if they have experienced any health problems or have become pregnant since they completed the study procedures.
This is a 2-arm, randomized, double-blind, double-dummy, and controlled clinical study, with 6 months of treatment to evaluate the clinical and metabolic efficacy of DLBS3233 in improving reproductive parameters and to evaluate the safety of DLBS3233 in women with polycystic ovary syndrome compared with metformin, as an active control.
The use of metformin pre-treatment and co-administration was recently proposed in infertile women affected by polycystic ovary syndrome (PCOS) treated with gonadotropins. Data from meta-analyses showed that metformin administration significantly reduced the stimulation length and the total dose of gonadotropins used in PCOS women undergoing gonadotropins stimulation for non in-vitro fertilization (IVF) cycles. On the other hand, in IVF cycles metformin was demonstrated to significantly reduce the ovarian hyperstimulation syndrome (OHSS) rate in infertile patients with PCOS treated with gonadotropins. The metformin regulating effect on the ovarian response was also observed in a randomized controlled trial (RCT) on young non-obese insulin-resistant women with PCOS receiving gonadotropins for mono-ovulation induction. In particular, metformin increased the mono-ovulatory cycles, the duration of stimulation and the amount of gonadotropins used, while it reduced the number of dominant follicles and the estradiol (E2) levels. The aim of the present study was to evaluate the effect of metformin administration in high responder PCOS patients undergoing gonadotropins ovarian stimulation for IVF cycles.
Increased plasma triglyceride concentration is a common feature of the metabolic abnormalities associated with obesity and a major risk factor for cardiovascular disease. Obesity is a major risk factor for two conditions that appear to be increasing in prevalence in women: the polycystic ovary syndrome (PCOS) and sleep disordered breathing. PCOS affects 5-8% of women. Sleep disordered breathing affects up to 10% of women. Obstructive sleep apnea (OSA) is the most common cause for sleep disordered breathing and particularly prevalent in obese women with PCOS (~50%). Both PCOS and OSA augment the increase in plasma triglyceride (TG) concentration associated with obesity, and the effects of PCOS and OSA on plasma TG concentration appear to be additive. The mechanisms responsible for the adverse effects on plasma TG metabolism are not known. The primary goal of this project, therefore, is to determine the mechanisms responsible for the increase in plasma TG concentration in obese women with PCOS and OSA. It is our general hypothesis that alterations in the hormonal milieu that are characteristic of these two conditions are, at least in part, responsible for the increase in plasma TG concentration in obese women with the conditions. Furthermore, we hypothesize that the hormonal aberrations characteristic of the two conditions are particularly harmful to obese, compared with lean, women. The effects of PCOS on skeletal muscle protein metabolism are also not known. However, sex hormones are thought to be important regulators of muscle protein turnover suggesting that muscle protein metabolism is likely to be affected by PCOS. We will examine this by determining the effect of individual sex hormones on muscle protein metabolism and hypothesize that testosterone administration will stimulate muscle protein metabolism while estrogen and progesterone administration will inhibit muscle protein metabolism.
