Filter by:We previously hypothesized that the excess of Anti-Mullerian Hormone (AMH) at the level of ovarian selectable follicles could be involved in the follicular arrest of Polycystic Ovary Syndrome (PCOS), mainly through inhibition of FSH effect on aromatase expression.In this study, we plan to investigate whether a drop in the serum AMH level would be concomitant to the appearance of a dominant follicle induced by administration of mild amounts of exogenous FSH in women with PCOS.
Hypothesis: The overall hypothesis is that women with PCOS, both obese and non-obese, have larger adipocytes, altered metabolism and signs of inflammation in adipose tissue and that these changes are associated with high sympathetic nerve activity, hyperandrogenism hyperinsulinaemia, insulin resistance with progression to type II diabetes and cardiovascular disease (CVD) as well as psychological distress and reduced quality of life. Physical exercise and electro-acupuncture decrease high concentrations of androgens, induce regulare menstrual pattern, inhibits high sympathetic activity and restore the PCOS induced disturbances.
The aim of this study is to aspirate immature oocytes from antral follicles and mature the oocytes in vitro. These mature oocytes will serve for fertilization and the creation of embryos which will be replace in the uterus as performed during normal IVF.We will record the efficacy and safety of this procedure.
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.
Lifestyle modifications are successfully employed in polycystic ovarian syndrome (PCOS) improving menstrual cycles and fertility. Unfortunately, the compliance over the time is very low. Recently, we have showed a high adherence to structured exercise training (SET) program in women with PCOS. The current study will be aimed to compare the efficacy of the SET program with a diet program on the reproductive function in obese anovulatory infertile PCOS patients.
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.
FlowMet study is a "sub-study" of the PregMet study (registered in 2005). The aim of the FlowMet study is to register the possible effect of metformin on the blood flow of the uterine artery in pregnant PCOS women. The participants will be examined with ultrasound Doppler in gestational week 10-13: 1. before and 3h after the first tablet intake of metformin/placebo 2. and 10-14 days after inclusion in the trial 3. blood flow in the umbilical artery and fetal cerebral artery in gestational week 24.
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 primary objective is to determine if meals of different fat and fiber content affect postprandial plasma testosterone concentration in women with polycystic ovary syndrome. Our hypothesis is that a high-fiber meal will have a greater reduction in testosterone composition compared with a high-fat meal.
Background: PCOS is a common condition with a prevalence of 5-8 % in premenopausal women. More than 50% of PCOS patients are insulin resistant and have a diabetes risk 5-8 times higher than age- and weight-matched controls. Studies using insulin sensitizers in PCOS found increased insulin sensitivity and decreased insulin levels to be followed by decreased androgen levels and improved ovulatory function. No studies however, evaluated the long term effects of insulin sensitizing treatment. Oral contraceptives normalize menstrual cycles and suppress androgen levels in PCOS, however no long-term studies evaluated the effects of combined treatment with metformin and oral contraceptives in PCOS. Design: Randomized open study in 3*30 PCOS patients. Patients are randomised to 24 months of treatment with 1: metformin, 2: metformin and oral contraceptives or 3: oral contraceptives. Primary outcome measures: fasting insulin, AUC insulin. Secundary endpoints: BMI, WHR, LH, FSH, total and free-testosterone, c-peptid, urinary cortisol, AUC for insulin, glucose and c-peptid during OGTT. Inclusioncriteria: 1. Irregular menses or anovulaty cycles 2. High free testosterone > 0,035 nmol/l or hirsutism 3. PCO in vaginal US Criteria 1 and 2 OR 2 and 3. Design:
