Filter by:Women with polycystic ovary syndrome (PCOS) are often insulin resistant. During pregnancy, insulin sensitivity decreases. The investigators examine glucose metabolism during oral glucose tolerance test and the incidense of gestational diabetes mellitus in a prospective cohort of pregnant women with PCOS and controls.
This is a double-blind randomized clinical trial which will start at June 2014 and end on June 2015 in Isfahan city. Serum insulin level is considered as a key variable and the sample size calculated 70 persons (35 persons for control group and 35 persons for patient group). Patient group will receive magnesium supplement (250 milligram) and the other group will receive placebo which is similar to the magnesium tablets in color, odor and appearance both for 8 weeks. All subjects will complete 4 physical activity and 4 dietary records. Outcome measurements including sex hormone levels, metabolic and inflammatory profiles will be measured at the beginning and end of the study as well as anthropetric measurements.
The study tests the hypothesis that correction of vitamin D deficiency among women with PCOS will improve insulin sensitivity and resistance and inflammatory response to PCOS.
1000 women with infertility who are already decided to be treated with ICSI will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by (Human menopausal gonadotrophin (HMG) stimulation until the day of (Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. Follicular sensitivity index (FSI) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH)
Women with polycystic ovarian syndrome (PCOS) have increased rates of hepatic steatosis compared to weight similar women with regular menses. It is unclear if this is related to high testosterone or insulin resistance. The investigators will assess hepatic glucose release, rates of lipolysis and hepatic de novo lipogenesis in the fasted and postprandial state to determine if alterations in the processes contribute to hepatic steatosis. Participants will be overweight, sedentary girls with or without PCOS. Those with PCOS will either be medication naive, or must be taking metformin or combined oral contraceptives (COCPs) for a period of at least 6 months prior to study procedures.
Women with PCOS suffer from excess male hormone (androgen) production by the ovary. Androgen is made by cells that surround follicles that contain eggs. As the follicles (and eggs) grow and mature, there are more androgen producing cells. Women with PCOS have more follicles than normal women and therefore more androgen producing cells. While androgen production has been associated with the number of follicles, the relationship to the individual size of follicles in PCOS or normal women. This study intends to determine whether the size and number of ovarian follicles are correlated to androgen production in PCOS and normal women.
Laparoscopic Ovarian Drilling is a valid procedure for infertile anovulatory women with polycystic ovarian syndrome who failed to get pregnant or to ovulate with ovulation induction medications as clomiphene citrate or exogenous gonadotropins. The reasearchers supposed that endometrial curettage at time of laparoscopic ovarian drilling may boost fertility in these women.
The primary aim of this study is to determine the effect of dopamine agonist therapy on insulin resistance in lean vs. obese women with polycystic ovary syndrome. Polycystic ovary syndrome (PCOS) is a common metabolic abnormality in women. The diagnosis of PCOS relies on a constellation of symptoms and signs (problems with ovulation, clinical and/or biochemical signs of hyperandrogenism and cystic ovaries). Though not a diagnostic feature, insulin resistance (IR) is a hallmark of PCOS and up to 80% women with PCOS have IR. Although IR is more significant in obese women with PCOS, even lean women can be insulin resistant. No current therapy addresses the problem of insulin resistance in PCOS. Studies have suggested a dopamine deficiency in patients with PCOS, which may underlie the insulin resistance and may have a pathogenetic role in the development of PCOS. No study to date has assessed the impact of dopamine agonist therapy on IR in patients with PCOS.
Polycystic ovary syndrome (PCOS) is an endocrine disease in reproductive women. It is characterized by anovulation and hyperandrogenism. Most patients with PCOS have metabolic abnormalities such as dyslipidemia, insulin resistance and glucose abnormalities. Almost 60-80﹪PCOS patients are obesity which exacerbates IR and hyperandrogenism. Obese PCOS patients tend to be overeating suggests that impaired appetite regulation might be contribute to the pathophysiology of PCOS. Our study is trying to observe difference of incretin between PCOS and normal control to figure out whether change of incretin is involved in the pathophysiology of PCOS.
Adults with abdominal obesity are at high risk for cardiovascular disease and also exhibit diminished growth hormone (GH) secretion; the latter further contributes to the development of visceral adiposity, impaired fibrinolysis and inflammation.Growth hormone releasing hormone (GHRH), the primary stimulus for endogenous GH secretion, is a substrate of dipeptidyl peptidase 4 (DPP4); inhibition of DPP4 with the currently available anti-diabetic therapy, sitagliptin, may therefore increase GH secretion by decreasing the degradation of GHRH. The proposed research will test the hypothesis that chronic sitagliptin therapy will enhance GH secretion and vascular function while improving glucose tolerance in patients with impaired GH secretion who are at risk for the development of diabetes mellitus and cardiovascular disease, specifically obese women with polycystic ovary syndrome.
