Active clinical trials for "Polycystic Ovary Syndrome"

Metformin increases the pregnancy rate when added to the standard treatment of anovulatory polycystic ovary syndrome (PCOS). Metformin in combination with clomiphene, is more effective than clomiphene alone or metformin alone improves fertility outcomes in women with PCOS of reasonably healthy body weight (BMI </= 32). Metformin improves fertility outcomes in women with BMI > 32 with PCOS.

Polycystic ovary syndrome (PCOS) is a common endocrinopathy affecting 6.5%-6.7% of women in reproductive age, and is commonly associated with obesity, menstrual irregularity, insulin resistance (IR), infertility, and clinical hyperandrogenism and/or hyperandrogenemia (1,2). PCOS is also associated with increased risk of abnormal lipoproteins and hypertension, as well as cardiovascular or cerebrovascular morbidity (3). The lipid and lipoprotein profile in androgenized women with poly cystic ovaries is similar to the made pattern with higher levels of cholesterol, low-density lipoprotein (LDL), and lower levels of high-density lipoprotein (HDL), and this abnormal pattern is independent of body weight (4). Insulin resistance is associated with reproductive abnormalities in women with PCOS. Improving insulin sensitivity through both lifestyle and pharmacological intervention can ameliorate these abnormalities. Insulin resistance in women with PCOS is common (up to 50%), both in obese and nonobese women (5), and disordered insulin action precedes the increase in androgen. Treatment for PCOS subjects typically includes, implementation of lifestyle changes especially weight loss and adjuvant pharmaceutical intervention including oral contraceptives, anti-androgen therapy and insulin-lowering drugs (such as, metformin) (6). Metformin is a biguanide used extensively in type 2 diabetes. It inhibits hepatic glucose production and increases peripheral insulin sensitivity, but dose not cause hypoglycemia. Several studies have shown an increase in insulin sensitivity and pregnancy rate accompanied by decreased insulin and androgen levels in PCOS patients taking metformin (7). The 3-hydroxy-3-methylglutaryl coenzyme A (HMG-COA) reductase inhibitors (statins) are the rate-limiting step in cholesterol biosynthesis, and inhibition of this enzyme decreases cholesterol synthesis and a compensatory increase in the expression of LDL receptors in the liver. Statins reduce plasma triglycerides in dose-dependent fashion and also have a modest HDL-raising effect which is not dose-dependent (8,9). Furthermore, statins pose other cardio-protective properties, including antioxidant and anti-inflammatory actions (10,11). Some studies have reported that simvastatin decreases serum androgen levels in women with PCOS (12,13) by inhibiting proliferation and steroidogenesis of ovarian theca-interstitial cells (14). According to these previous findings, we hypothesized that combination therapy with simvastatin and metformin will result in lower androgen levels and cardiovascular risk factors in women with PCOS.

The purpose of this study is to determine whether metformin may improve pregnancy rates, and decrease miscarriage rates and complications of pregnancy, such as toxemia and gestational diabetes, in women with polycystic ovary syndrome (PCOS).

This study has two phases: In phase 1 of the study (8 weeks),the effect of two different low calorie diets on manifestations of PCOS, including risk factors for the metabolic syndrome and cardiovascular risk profile will be compared. In phase 2 the long term effect (next 44 weeks) on sustained weight-loss and the above mentioned parameters will be compared and evaluated.

To date, it is still unclear the potential role of laparoscopic ovarian diathermy (LOD) in the management of polycystic ovary syndrome (PCOS)-related anovulatory infertility. Metformin administration, alone or combined with clomiphene citrate (CC), has shown to be an effective and attractive second-line treatment for ovulation induction in women with polycystic ovary syndrome (PCOS) after failure of CC treatment. The aim of the present study will be to compare in a randomized controlled fashion the efficacy of LOD with metformin plus CC administration in the treatment of the CC-resistant PCOS patients.

The purpose of this study is to determine if the combination therapy of lifestyle intervention and use of Metformin together will improve ovulation induction and hyperandrogenemia in women with polycystic ovary syndrome, by gathering data from adult and adolescent females.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting up to one in five reproductive-aged women. It is associated with clinical and/or biochemical hyperandrogenism, oligomenorrhea, and polycystic appearance of ovaries in ultrasonography. Voice changes have been traditionally recognized as a feature of PCOS for years. However, voice analyses of patients with PCOS are limited. The human larynx is a highly hormone-sensitive target with the presence of hormonal receptors within the vocal folds, and vocal changes occur in relation to the fluctuations in the sex hormones. During the reproductive years and throughout the menstrual cycle, vocal changes have been reported in almost one-third of nonprofessional voice users.The aim of this work is to evaluate the voice characteristics among women with PCOS

The purpose of this study is to assess the effects of Time restricted eating in patients diagnosed with polycystic ovary syndrome, comparing it to the standard hormonal treatment.

The aim of this study was to evaluate the effect of oral L-carnitine supplementation during controlled ovarian stimulation (COS) in patients with polycystic ovary syndrome (PCOS) in a double-blind randomized clinical trial. The eligible patients with PCOS diagnosis (on the basis of Rotterdam criteria) who referred to Royan Research Institute for IVF / ICSI treatment cycles will be evaluated.

The main aim of this study is to evaluate the effect of myo-inositol and alpha-lactalbumin treatment on HOMA-index improvement in two different groups of women, belonging to the Mexican and Italian population, both affected by Polycystic Ovary Syndrome.
