Active clinical trials for "Polycystic Ovary Syndrome"

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).

In this study, the investigators wish to investigate how pioglitazone treatment effects hirsute women. Hirsute women are often overweight and have an increased amount of male sex hormone in their blood. Their blood tests show frequent changes corresponding to the changes seen in diabetic patients. Pioglitazone is a drug used for increasing the insulin sensitivity in diabetic patients. Previous studies showed that this drug is able to decrease the level of insulin in blood in hirsute women. Moreover, the level of male sex hormones is reduced during this treatment. The drug has only been marketed for few years, and no investigations have been carried out as to the reaction of other hormones, e.g. growth hormone and stress hormone, using this treatment. This clinical trial includes 30 strongly hirsute women. The patients are randomized to either placebo or an active drug. The treatment period is 16 weeks. The patients included must be healthy and take no medicine possibly changing the results of the study. The patients must take no contraceptive pills or receive any other hormone treatment. In connection with the investigation, the following will be carried out on all patients: glucose tolerance test, clinical examination, blood tests, measurement of stress hormones and sex hormones, hyperinsulinaemic euglycaemic clamp test, muscle biopsies and bone scan. This examination programme will be carried out before start of pioglitazone or placebo treatment and again after 16 weeks of treatment. The examinations require 2½ days of hospitalization. The purpose of the study is to gain more knowledge of the reasons for hirsute women to grow more hair than normal women. The study will show whether pioglitazone treatment can reduce the amount of male sex hormone in blood and how the level of stress hormone and growth hormone is changed when reducing the amount of insulin in blood.

OBJECTIVES: I. Evaluate insulin resistance in thin and obese hyperandrogenic women with polycystic ovarian disease or hyperandrogenism insulin resistance acanthosis nigricans syndrome and in thin and obese controls, using an estimation of tissue sensitivity to insulin. II. Evaluate the effect of androgen suppression with leuprolide acetate and spironolactone on insulin secretion and resistance.

This study aimed to understand whether metformin therapy can improve insulin resistance in adolescent PCOS patients, both during treatment and after discontinuation, and to evaluate its action on the hormonal and metabolic pathways.

The Quantum Menstrual Health Monitoring Study will measure four key reproductive hormones in the urine to characterize patterns that predict and confirm ovulation, referenced to serum hormones and the gold-standard of the ultrasound day of ovulation in participants with regular cycles. These normal cycles will provide a reference for comparison to irregular cycles in polycystic ovarian syndrome (PCOS) and athletes. Clinical signs in the menstrual cycle (e.g. menstrual bleeding, temperature) as well as vital sign and sleep patterns will also be referenced to hormonal changes.

The use of GnRH antagonist protocol nowadays is the slandered protocol of controlled ovarian stimulation in patients with poly cystic ovarian syndrome (PCOS) because it decreases the incidence of OHSS(1, 2). However, this protocol may lead to asynchronous growth of follicles with an early dominant follicle specially in PCOS patients(3). In most of cases this phenomenon will affect the IVF outcomes(2, 4) Aromatase inhibitors (AIs) nowadays is recommended to be used for ovulation induction in patients with PCOS (5, 6).It has fewer side effects, and a shorter half-life than clomiphene citrate(CC), and no effect ON the endometrial receptivity. It is used in treating patients with chronic anovulation, unexplained infertility and poor ovarian reserve(7). It acts through decreasing estrogen levels and allows follicle stimulating hormone (FSH) release from the hypothalamus (8, 9). It could be used alone or with combination with human menopausal gonadotropin (HMG) specially in patients with CC resistant(10-13). It also improves the ovarian response to FSH when they are used in combination and it decreases the risk of OHSS (14). This study aims to evaluate the effect of uses of letrozole in combination with HMG during ovarian stimulation in patients having PCOS undergoing IVF/ICSI on the follicular growth pattern, synchronized growth of follicles, maturity of oocyte and the quality of embryos.

The purpose of the study to evaluate effect of nitroglycerin trans-dermal patches on uterine and sub-endometrial blood flow in women with unexplained infertility.

Polycystic Ovary Syndrome (PCOS) is a complex hormonal and metabolic disorder that has been shown to affect women's fertility. It can also share many symptoms with pre-diabetes, and women with PCOS often have an increased risk for type 2 diabetes, heart attack and stroke. This study aims to assess the feasibility and acceptability of exercise intervention and increased lifestyle physical activity to improve cardiovascular disease risk factors in women with PCOS.

The Investigators will measure hepatic glucose and fat metabolism in obese girls with Polycystic Ovarian Syndrome (PCOS) and hepatic steatosis (HS) after taking 4 weeks of an essential amino acid (EAA) supplement or placebo and test whether the EAA supplement can improve hepatic glucose metabolism in these girls.

Polycystic ovary syndrome is the most common endocrine and metabolic disorder in gynecology. Traditional Chinese medicine has a good clinical effect in the treatment of PCOS. We intend to conduct this trial in strict accordance with the requirements of evidence-based medicine, through a multi-center, randomized, controlled study, using a double-blind, randomized, placebo-controlled study design method to clarify that Zishen Qingre Lishi Huayu Recipe restores spontaneous ovulation in PCOS patients. The overall efficacy of improving the characteristics of Kaohsiung and glucose and lipid metabolism is optimal, and high-level evidence-based evidence is obtained to form a diagnosis and treatment plan for promotion.
