Filter by:The purpose of our study was to conduct a placebo controlled, double-blind randomized trial in chronic oligoovulatory or anovulatory , hyperandrogenic, infertility patients comparing the effects of adjuvant metformin plus clomiphene citrate to clomiphene citrate plus placebo on pregnancy rates and ovulation rates. We hypothesized that combining metformin with clomiphene citrate would result in higher ovulation and pregnancy rates in hyperandrogenic women who have chronic oligoovulation or anovulation as the sole etiology for their infertility and who have unknown responsiveness to clomiphene citrate.
The purpose of this study is to compare effects of statins (simvastatin) and metformin on clinical (menstrual cycle, excessive hair, skin problems), endocrine (androgens), metabolic (lipids, markers of systemic inflammation), and endothelial function parameters in women with polycystic ovary syndrome (PCOS).
PolysCsytic Ovaries Syndrome (PCOS) is the most frequent endocrinopathy. The first stage of infertility treatment is Clomiphene Citrate which leads to 50 % pregnancies. In case of failure, it is possible to propose surgical ovarian drilling or ovarian hyperstimulation with Intra Uterine Insemination (IUI) which lead to 50% pregnancies each. However, surgical treatment could be associated to surgical complications, and medical treatment could be associated to ovarian hyperstimulation syndrome and/or multiple pregnancies. The aim of this study is to compare the two treatments to demonstrate the equivalence of efficacy and the diminution of multiple pregnancies by the surgical treatments. After an ambulatory surgery we will observe the spontaneous fertility during 9 months. For the medical treatment, Metformin is proposed during 9 months associated with 3 cycles of ovarian hyperstimulation and IUI if the sperm is normal
The purpose of this study is to determine whether statins (simvastatin) improve clinical (excessive hair, skin problems), endocrine (androgens) and metabolic (lipids, markers of systemic inflammation) in women with polycystic ovary syndrome (PCOS).
Polycystic ovary syndrome (PCOS) is among the most common endocrine disorders in premenopausal women, affecting 7-10% of this population. This syndrome is characterized by elevated levels of testosterone and chronic anovulation, and frequently of obesity. This study is designed to test the hypothesis that there is in utero testosterone excess, altered insulin secretion, and/or intrauterine growth retardation in the female offspring of women with PCOS. The allele 8 can be used to identify the reproductive and metabolic abnormalities associated with PCOS. This study will determine whether allele 8 positive [A8(+)] female offspring have more profound changes in these parameters compared to A8(-) female offspring. Androgen and insulin levels in amniotic fluid from pregnant women with PCOS will be compared to levels in pregnant control women. Androgen and insulin levels in cord blood will also be measured. Further, gestational age and anthropomorphic measurements in offspring of women with PCOS will be assessed and compared to that in offspring of matched control women. We will test the hypothesis that androgens are elevated in infancy in the female offspring of women with PCOS. We will assess sex steroids, insulin, and c-peptide levels in infants of PCOS women and compare them to the levels in infants of control women up to 1 year of age during the minipuberty of infancy. We will determine whether any of these parameters differ in A8(+) compared to A8(-) PCOS offspring.
Current research has shown that the use of diabetes management practices aimed at reducing insulin resistance and hyperinsulinemia (such as weight reduction and the administration of oral antidiabetic drugs) in women with PCOS can not only improve glucose and lipid metabolism but can also reverse testosterone abnormalities and restore menstrual cycles. A new medicine called exenatide (Byetta) has been found to reduce body weight, as well as, improve abnormal glucose metabolism in diabetics. This randomized study will compare Exenatide (Byetta) to extended release metformin (Fortamet) to combination therapy (both Byetta and Fortamet) on menstrual cyclicity, hormone profiles and metabolic profiles over a 24-week period in women with PCOS.
Polycystic Ovary Syndrome (PCOS) is manifested as a heterogeneous mixture of clinical and bichemical characteristics that complicate study of its etiology. It is currently unclear to what extent PCOS-associated traits (hyperandrogenism, hyperinsulinemia, insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity, and coronary artery disease) are the result of environmental factors or genetic predisposition. We propose to conduct a twin study to investigate the possibility that environmental factors are important in the development of the PCOS phenotype. Twin studies are considered to be the gold standard for determining the extent of heritability of a trait. The proposal described here is only for Step 1 of a larger, multi-step study. The major goal of step 1 is to identify a large cohort of twin pairs, in which at least one member of each pair is likely to have PCOS. Participants for this study will come from the Mid-Atlantic Twin Registry (MATR). Many (3283) potential participants have already been identified based on their answers to a preliminary MATR screening questionnaire. Out of the approximately 7145 twin women of reproductive age who completed these MATR screening questionnaires, 1803 women reported irregular periods, 954 reported ovarian cysts, and 526 reported both irregular periods and ovarian cysts. Many of the women in this last group are likely to have PCOS. They represent 7.4% of the total sample, matching current estimates of PCOS prevalence (4-7%) in reproductive age women. We will also add new twin pairs who meet the criteria (irregular periods and evidence of PCOS or cystic ovaries) as they are recruited into the MATR and take the preliminary surveys. According to MATR statistics, about 33% of twin pairs are monozygotic (MZ, identical). Therefore, approximately 174 of the 526 women likely to have PCOS are members of a MZ pair. Step 1 of the proposed study consists of a telephone survey of the 3282 women with irregular periods and/or ovarian cysts. The survey will be conducted by the MATR. The instrument to be used contains a series of simple and direct questions and will take about 10 minutes to complete. The questions were designed to identify PCOS and their content deals with the frequency of menstrual periods (six or fewer per year being a major diagnostic criterion), a previous diagnosis of PCOS, obesity, excess facial hair and other evidence of hyperandrogenism. The women will also be asked if t...
The purpose of this study is to determine whether oral cinnamon extract are effective in reducing insulin resistance parameters in women with polycystic ovary syndrome.
Insulin resistance is an important feature of the polycystic ovary syndrome,and patiens are successfully treated with the insulin sensitizing agent metformin. The insulin resistance of lean patients with the syndrome is debated. In this study, we will study the change in insulin resistance, metabolic and hormonal factors after 3 months of metformin treatment in lean PCOS women.
Hypothesis: Metformin treatment normalises hormone values and metabolic parameters in women with PCOS. Ovulation is restored and bleeding periods become regular. Fifty women with PCOS (Rotterdam criteria) are randomised to either placebo or metformin for 6 months. After a wash-out period of 3 months, the opposite treatment is given for another 6 months. Measurements are performed before ech treatment period, every second month during treatment and after completing treatment.
