Filter by:Background: - Polycystic ovarian syndrome (PCOS) is a group of disorders related to problems with the secretion of certain hormones, which can lead to reproductive and other issues in women. Frequent complications of PCOS include irregular menstruation, development of ovarian cysts, and insulin resistance. The adrenal glands, which sit on top of the kidney, are involved in the production of certain hormones and the regulation of steroid levels in the blood, and may be affected in women with PCOS. Researchers are interested in studying possible connections between the adrenal glands and PCOS in young women who have been diagnosed with PCOS and healthy volunteers with normal menstrual function. Objectives: - To investigate possible connections between adrenal gland steroid hormone secretion and polycystic ovarian syndrome. Eligibility: - Women between 16 and 29 years of age who have been diagnosed with PCOS, or who are healthy volunteers with normal menstrual function. - Participants must be willing to discontinue the use of oral contraceptives or any other medications that alter steroid hormone production for at least 1 month before the start of the study. Design: - Participants will be screened with a physical examination, medical history, and blood and urine tests. All participants will also have a pelvic (ovarian) ultrasound. - All participants will be admitted to the hospital for a 1-week testing period, which will involve the following tests: - Regular blood draws for two 2-hour periods (late evening and early morning) to measure hormone levels - Fasting blood draws with a dose of corticotropin to test the body's adrenal function - Hormone level measurement following regular doses of dexamethasone (a drug that controls the function of the adrenal gland) - Daily urine collection for 6 days. - Other studies, such as imaging studies of the adrenal glands, may be conducted as required by the study researchers.
This study aimed to search whether whole body and subcutaneous adipose tissues increase in PCOS patients and whether these tissues are related to HOMA-IR and plasma adiponectin levels.
The purpose of our study is to evaluate the effectiveness of a lifestyle program for women with Polycystic Ovary Syndrome (PCOS). The investigators want to assess the effect of a pulse-based diet (i.e. a diet that contains lentils, chick-peas, peas, and beans) and aerobic exercise for improving PCOS disease features and risk factors for metabolic syndrome. We would like to determine the therapeutic effects of a lifestyle program that combines a pulse-based diet and exercise on the multiple disease measures of PCOS and metabolic syndrome.
This study is a prospective randomized clinical trial to compare the endocrine and metabolic effects of two anti diabetic drugs (metformin vs. acarbose) in infertile overweight women with PCOS
The aim of the present study was to search whether epicardial adipose tissue thickness, a predictor of increased cardiovascular risk, increases in PCOS patients or not and, if it does, to analyze the relationship of EATT with insulin resistance, adiponectin and biochemical and anthropometric parameters.
Polycystic ovary syndrome (PCOS) is an extremely common disorder in women of reproductive age. Diagnosis of PCOS is principally based on clinical and physical findings. Diagnostic criteria and PCOS definitions used by clinicians and researchers are almost as heterogeneous as the syndrome. This first part of study is determine whether genetic polymorphisms influence hormonal and metabolic characteristics in Taiwanese patients with PCOS and controls. Furthermore, women with PCOS were reported with high risk of cardiovascular disease, the investigators planned to calculate the difference of carotid intima-media thickness (IMT) and B-type natriuretic peptide (BNP) between women with PCOS and normal control to determine the premature atherosclerosis of women with PCOS.
Polycystic ovary syndrome (PCOS) is an extremely common disorder in women of reproductive age. Diagnosis of PCOS is principally based on clinical and physical findings. Diagnostic criteria and PCOS definitions used by clinicians and researchers are almost as heterogeneous as the syndrome. Of those diagnosed with PCOS using the 2003 Rotterdam criteria, 61% fulfilled 1990 NIH criteria for unexplained hyperandrogenic chronic anovulation. The patient populations with the new phenotypes had less severe ovulatory dysfunction and less androgen excess than patients diagnosed using the 1990 NIH criteria. These findings might be common across all female populations with PCOS, whether in Oriental or Occidental countries. Data for clinical hyperandrogenism indicated that the prevalence of hirsutism in Taiwanese PCOS women is lower than that for Caucasians/Western women. The extent of metabolic abnormalities in women with PCOS may vary with phenotype, age and ethnicity. Obesity represents a major risk factor for metabolic syndrome and insulin resistance. Approximately 40-50% of all women with PCOS are overweight or obese. Obese subjects with PCOS had a higher risk of developing oligomenorrhea, amenorrhea and biochemical hyperandrogenemia than non-obese women with PCOS. Moreover, obese women with PCOS had significantly more severe insulin resistance, lower serum LH levels, and lower LH-to-FSH ratios than non-obese women with PCOS. PCOS women in Taiwan presented with higher LH-to-FSH ratio and lower insulin resistance than PCOS women in Western Countries. However, the average body mass index (BMI) was significantly lower in Taiwanese PCOS women than Western women, which might partially explain the difference between these two populations in terms of clinical and biochemical presentations. To further document the ethnic variation between women with PCOS in Taiwan and Western, the effect of obesity on the diagnosis and clinical presentations of PCOS-related syndromes should not be neglected in future studies. Therefore, the investigators plan to do this prospective study for evaluation the clinical and biochemical presentation of Taiwanese women with PCOS.
This pilot study will be a prospective investigation to study the efficacy and safety of In-Vitro Maturation (IVM) for women with Polycystic Ovarian Syndrome (PCOS). There will be 10 subjects total in this Study. There will be no blinding to treatment. In-Vitro Maturation will provide a viable, safe option for women with PCOS attempting pregnancy through the use of Assisted Reproductive Technology (ART).
The use of metformin pre-treatment and co-administration was recently proposed in infertile women affected by polycystic ovary syndrome (PCOS) treated with gonadotropins. Data from meta-analyses showed that metformin administration significantly reduced the stimulation length and the total dose of gonadotropins used in PCOS women undergoing gonadotropins stimulation for non in-vitro fertilization (IVF) cycles. On the other hand, in IVF cycles metformin was demonstrated to significantly reduce the ovarian hyperstimulation syndrome (OHSS) rate in infertile patients with PCOS treated with gonadotropins. The metformin regulating effect on the ovarian response was also observed in a randomized controlled trial (RCT) on young non-obese insulin-resistant women with PCOS receiving gonadotropins for mono-ovulation induction. In particular, metformin increased the mono-ovulatory cycles, the duration of stimulation and the amount of gonadotropins used, while it reduced the number of dominant follicles and the estradiol (E2) levels. The aim of the present study was to evaluate the effect of metformin administration in high responder PCOS patients undergoing gonadotropins ovarian stimulation for IVF cycles.
According to the studies CC is successful at inducing ovulation in 50%-75% of cases, but only 30-40% becomes pregnant. The difference has been attributed to a negative action of clomifen citrate(CC) in the form of prolonged antiestrogenic effects on endometrial receptivity. For avoiding of these negative effects, giving ethinyl estradiol in sufficient dosages may be effective. The purpose of this study is comparing pregnancy rates after IUI in women who use CC alone and those who use CC in combination with ethinyl estradiol
