Active clinical trials for "Polycystic Ovary Syndrome"

OBJECTIVES: I. Determine whether reduction of serum insulin levels by metformin increases ovulatory response to clomiphene or spontaneous ovulation in obese women with polycystic ovary syndrome.

The purpose of this study is to compare and determine the efficacy of combined N-acetyl cysteine and clomiphene citrate(CC)with combined metformin and CC in infertile women with Polycystic ovary syndrome(PCOS)not responding to treatment with Clomiphene alone.

Cardiovascular risk factors cluster in hyperandrogenic women - including those presenting with the polycystic ovary syndrome - in association with insulin resistance, obesity, and other metabolic disorders. The present clinical trial intends to compare the effects of oral contraceptives and metformin on PCOS patients, focusing on classic and non-classic cardiovascular risk markers and indexes of cardiovascular performance, in order to whether or not, as suspected by previous data obtained in non-hyperandrogenic women, oral contraceptives worsen the cardiovascular risk profile of PCOS women, favoring the use of metformin if the latter actually ameliorates such a risk.

The primary aim of the study is to assess the efficacy of letrozole as an ovulation induction agent and to test the hypothesis that letrozole will generate better pregnancy rates with fewer multiple pregnancies and higher live birth rate than the current standard agent, clomifene citrate in anovular infertile women with polycystic ovarian syndrome.

Clomiphene citrate (CC) and metformin are two effective drugs used to induce ovulation in patients with polycystic ovary syndrome (PCOS), even if it is still unclear which compound between them should be initially administered. The aim of the study will be to compare in a clinical setting the efficacy of CC and metformin as first-line approaches for treating anovulation in infertile PCOS patients.

Studies on the effect of sibutramine, an anti-obesity drug, on hormonal and metabolic features of women with polycystic ovary syndrome (PCOS) are lacking. The objective of this study is to examine the effect of sibutramine plus hypocaloric diet on body composition, hormonal and metabolic parameters and insulin resistance in obese patients with PCOS. Overweight and obese women with PCOS were placed in a hypocaloric diet plus sibutramine (10 mg/day) for the first month and then on a hypocaloric diet plus sibutramine (10 mg/day) or hypocaloric diet only for the subsequent 6 months. The main outcome measures are: Body composition, hormonal and metabolic features and insulin sensitivity (OGTT) at baseline, at 3 and 6 months of treatment.

The polycystic ovary syndrome is the major cause of infertility in the United States. Metformin has been shown to increase frequency of ovulations in PCOS, and is used in clinical practice to treat infertility, but some women with PCOS do not respond to metformin treatment. Knowing that a specific gene predicts the effect of metformin on ovulation would facilitate more efficient and effective treatment of infertility in PCOS.

This multicenter, randomized, open-label exploratory study will be performed in approximately 200 polycystic ovary syndrome (PCOS) but otherwise healthy females undergoing in vitro fertilization (IVF). Each study center will follow its standard practice for in vitro fertilization (IVF) within the study parameters as noted in this protocol. The study centers will use marketed products purchased from Schraft's Pharmacy for all phases of the study (down-regulation, stimulation, ovulation induction, and luteal support). Subjects will be randomly assigned to highly purified menotropin (Menopur®) or follitropin beta (Follistim Pen®) for stimulation and progesterone vaginal insert (Endometrin®) or progesterone in oil for luteal support. Subjects will return to the study center for regular scheduled clinic visits as required per in vitro fertilization (IVF) protocol at the site and at specified times during the cycle (Stimulation Day 6, Day of human chorionic gonadotropin (hCG), and first serum pregnancy test) for estradiol (E2), progesterone (P4) and human chorionic gonadotropin (hCG) labs. All subjects will be required to complete a final study visit at completion of luteal support or negative serum pregnancy test following embryo transfer.

The investigators conducted a prospective un-blinded pilot study of Vitamin D plus Calcium (Ca) supplementation in overweight (BMI > 27) premenopausal women diagnosed with Polycystic Ovarian Syndrome (PCOS), as defined by the Rotterdam Criteria, 2003, and who were deficient in vitamin D as reflected by serum 25-hydroxy (25-OH) vitamin D (serum levels < 20 ng/mL).

Hypothesis The overall hypothesis is that non-obese (BMI <30) women with PCOS have high luteinising hormone (LH) and cortisol pulse frequency and amplitude and that repeated low-frequency EA restore these alterations and induce ovulation.
