Filter by:To assess the prevalence of endometrial hyperplasia (EH), endometrial intraepithelial neoplasia (EIN) and endometrial carcinoma between obese and not obese women undergoing IVF techniques for primary or secondary infertility.
Girls with obesity and polycystic ovarian syndrome will receive either glucagon like peptide-1 receptor agonist therapy or a dietary intervention for 12 weeks to decrease the metabolic syndrome, in particular to lower hepatic fat and improve insulin sensitivity.
Compare weight loss and metabolic parameters in patients using a low starch dietary education program vs. traditional treatment (i.e., prescribing metformin, low calorie diet and exercise) for health improvement in women with PCOS.
Clinical use of IVM was pioneered in the nineties, but has not yet become a realistic option for wide-scale practice, for several reasons. Fundamentally, despite recent progress in improving the implantation and the pregnancy rates using in-vitro matured oocytes, results of IVM remain lower than treatment cycles utilizing conventional ART. To improve the outcome of IVM cycles, this study focuses on improving in-vitro culture conditions. In-vitro maturation (IVM) of human oocytes obtained from minimally stimulated or unstimulated ovaries offers a more "patient friendly" treatment option than the conventional Assisted Reproductive Technology (ART) treatment with controlled ovarian hyperstimulation (COH). Typically, IVM will be offered to women with polycystic ovaries (PCO/PCOS), or to patients with an excellent ovarian reserve, i.e. a high antral follicle count. IVM treatment is characterized by minimal administration of FSH or hMG and NO hCG trigger. The IVM approach is less disruptive to patients' daily life through the reduced need for hormonal and ultrasound monitoring, avoids a range of minor and major complications, such as ovarian hyperstimulation syndrome, and aims to reduce the total cost of infertility treatment for the patient and for the health care budget. Human oocytes retrieved from small antral follicles are able to resume meiosis by undergoing germinal vesicle breakdown and extrusion of the first polar body, if oocytes have reached meiotic competence. These oocytes can be fertilized although only a proportion (less than 50%) of them can develop further into viable embryos. It has been hypothesized that failure of embryonic development may, at least in part, be due to an immature oocyte cytoplasm. A novel human in vitro maturation (IVM) culture system (named CAPACITATION-IVM is being investigated, hereafter named "CAPA") using 1°) natural compounds known to influence cAMP levels within the cumulus-oocyte-complex and 2°) compounds that are crucial for the oocyte-cumulus cross-talk. Keeping cyclic AMP high after retrieval in the GV oocyte prevents the occurrence of nuclear maturation, enabling increased communication between the oocyte and the cumulus cells. This allows for the improvement in the synchronization of nuclear and cytoplasmic maturation processes in the oocyte, to the benefit of embryo quality.
To assess whether Vitamin D supplementations for patients with polycystic ovary syndrome in conjunction with clomiphene citrate are beneficial or not
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.
A randomized controlled trial to evaluate whether pretreatment with myo-inositol can lower testosterone levels and improve clinical outcomes in hyperandrogenic PCOS patients undergoing ART
The Offspring Born to Mothers with Polycystic Ovary Syndrome in Guangzhou Cohort study (PCOS-BIG) was established to investigate the short- and long-term effects of intrauterine exposure to maternal PCOS on the health of offspring in Guangzhou, China. Data are collected regarding maternal PCOS subtypes, nursing, diet and education as well as health outcomes in their later life. Biological samples including blood and tissue samples are also collected from participants.
The investigator's aim is to evaluate if the combination of myo-inositol and alpha-lactalbumin can overcome the resistance to myo-inositol in PCOS patients
Testing two different strategies for weight loss intervention and revealing possible changes in composition of gut microbiota, in order to provide more insight in the effect of dietary changes and weight loss treatments on gut microbiome in overweight and obese women with polycystic ovary syndrome (PCOS). The two strategies are: - dietary advice plus myo-inositol and folic acid - dietary advice plus liraglutide, glucagon-like peptide-1 (GLP-1) receptor agonist Primary outcome will be weight loss. Secondary outcomes are longitudinal changes in clinical features associated with PCOS and metabolic syndrome, longitudinal changes in gut microbiome with interventions. Subjects will be treated during 16 weeks and follow-up will take 16 weeks after stop of treatment.
