Active clinical trials for "Polycystic Ovary Syndrome"

measuring serum gherlin in polycystic ovary syndrome patients and compare it to healthy levels

Our study is observational, we are observing data from routine measurements during IVF/ICSI. Our study does not assess IVF/ICSI as an intervention, we are evaluating the role of FSI and preovulatory count which are calculated by observing routine measurements during the IVF/ICSI procedure. 300 women with polycystic ovarian syndrome (PCOS) who are 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 follicle stimulating hormone (FSH) 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 output rate (FORT) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH). FORT correlation to pregnancy will be compared to that of the preovulatory count number

The purpose of this study is to elucidate the significance of adipocytokine in women with PCOS among adiposity, hyperandrogenism and insulin resistance.

PCOS is a common endocrinopathy affecting 5-10% of women in their reproductive age characterized by hyperandrogenism, chronic anovulation and polycystic ovaries. This syndrome is a serious problem in IVF since there is a high risk of developing ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation with gonadotropins. The introduction of GnRH antagonist in IVF has reduced the incidence of severe OHSS, still maintaining a good ovarian response and pregnancy rate. Recently, a long acting GnRH antagonist, Degarelix, was introduced for prostatic cancer treatment. Furthermore a recent paper reported its use also for the induction of multiple follicular growth in a program of oocyte donation. The aim of this study is to evaluate the feasibility of GnRH antagonist depot use in a protocol of controlled ovarian hyperstimulation in PCOS women at risk of developing OHSS in IVF cycles.

Polycystic ovary syndrome (PCOS) is the most common cause of ovulation disorders and affects 10 to 15% of women. Despite its frequency, its physiopathology remains unknown. In women, Anti-Müllerian hormone (AMH) is secreted by granulosa cells located in the ovaries within the follicles. Compared to control women, serum AMH level is higher in PCOS women and could play a role in its pathophysiology. The severity of the PCOS phenotype is correlated with the production of AMH. It is currently described in the literature that daughters of women with PCOS have a 50% risk of developing PCOS, but no genetic cause of transmission is known. In mice (article in press), pregnant females injected with AMH give birth to offspring with PCOS symptoms. The AMH could thus also play a role in the heritability of PCOS in women. Our team demonstrated that AMH, in its active cleaved form, had a direct central action on the hypothalamus by increasing the pulsatility of GnRH, inducing LH hypersecretion. The hypothesis is that AMH remains higher in pregnant women with PCOS and may affect the fetus by altering fetal and maternal hypothalamic secretions or by modifying placental steroid production. Leptin has a role in reproduction, through its receptors located at the central (hypothalamus) and peripheral (granulosa cells) levels. In excessively high serum concentration, as observed in obesity, it would lead to a dysregulation of GnRH secretion, an alteration of ovarian steroidogenesis and a dysregulation of folliculogenesis. Will be compare leptin levels in first trimester patients with and without PCOS to look for possible correlations between AMH and leptin and eliminate possible bias.

Women with PCOS and OSA, compared to women with PCOS only, have more severe clinical and biochemical features of PCOS and impaired QoL. This is an observational cross-sectional study in a secondary care PCOS clinic in the WISDEM Centre, University Hospital Coventry. The primary aim of this study is to examine the relationship between OSA and impaired QoL in women with PCOS. Study secondary outcomes are to examine the relationship between OSA and the clinical and biochemical features in women with PCOS.

The primary aim of the current study is to clarify whether serum vitamin D levels [25(OH)D3] have a temporal association with insulin resistance and/or insulin sensitivity in PCOS women versus healthy ones. To achieve this aim, the investigators will conduct a prospective observational study involving obese and lean PCOS women in comparison to obese and lean healthy subjects living in Cairo, Egypt.

The study is prepared to use CMR technology for early screening of myocardial lesions in 561 age-matched women with type 2 diabetes without PCOS, with PCOS without type 2 diabetes and with type 2 diabetes combined with PCOS, compare the differences between the two groups of cardiomyocyte injury changes, and treat and follow-up with type 2 diabetes and PCOS in accordance with the current standard treatment guidelines for type 2 diabetes and PCOS, after 3 years of follow-up we will analyse the changes in cardiomyopathy, cardiac serological indicators, and heart function indicators,which can provide theoretical basis for early clinical intervention in the future.

evaluation of the potential role of circulating Nesfatin-1 and Nicotinamide in patients with polycystic ovary syndrome. and detection the correlation between Nesfatin-1 and body mass index (BMI), Waist hip ratio (WHR), blood glucose, insulin, insulin resistance, lipid profiles, prolactin, LH, FSH, estrogen, progesterone, testosterone and dopamine.

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.
