PCOS is a common condition that frequently presents in adolescence and young adulthood and is defined by elevated androgens (male hormones) in the blood leading to 1. hirsutism and acne and 2. menstrual abnormalities or amenorrhea. Affected individuals are at increased risk of developing insulin resistance (a precursor of diabetes), NAFLD and lipid (cholesterol) abnormalities.These features are all associated with the metabolic syndrome, a rising major public health concern. Recently, an association between PCOS and NAFLD has been noted but has only been superficially studied in the adolescent and young adult population. The susceptibility of certain PCOS patients to developing NAFLD is theorized to be due to having underlying insulin resistance, elevated androgen levels, and a genetic predisposition. Metformin is an insulin sensitizing medication widely used to treat type 2 diabetes mellitus that may have beneficial effects on insulin resistance-related conditions including PCOS and NAFLD. Although widely used in PCOS, its effect on NAFLD in this group has not been previously studied. The primary aims of this proposal are: 1) To determine whether PCOS with liver fat >/=4.8% treated with metformin for six months will have a decline in percentage liver fat compared to a placebo group. 2) To measure the association of the PNPLA3 I148M allele with NAFLD in PCOS at baseline (n=40). 2b) To measure the association of percentage liver fat with biomarkers of NAFLD, dyslipidemia, insulin resistance and body composition at baseline (n=40) and after a placebo-controlled intervention with metformin in PCOS with liver fat >4.8% (n=20). The goal of this research proposal is to explore the use of novel and noninvasive technologies in a young and at risk population. Dr. Sopher hopes to use the results of this research to lay the groundwork for the prevention and treatment of NAFLD and other metabolic disorders in adolescents and young adults with PCOS and to prevent lifelong morbidity associated with PCOS.
Polycystic ovary syndrome (PCOS) has a heterogeneous clinical presentation comprising reproductive (hyperandrogenism, menstrual irregularity, anovulation, infertility, pregnancy complications), metabolic [insulin resistance (IR), increased type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) risk factors] and psychological features (worsened quality of life and increased anxiety and depression) Whether prolonged fasting during Ramadan breaks the insulin resistance state of polycystic ovarian syndrome and subsequently improve the ovulation and spontaneous pregnancy will happen without ovarian stimulation.
This study evaluates the feasibility and metabolic effects of implementing a structured exercise program in women with polycystic ovary syndrome and insulin resistance. Participants will be randomized to either 75 minutes of vigorous exercise or 150 minutes of moderate exercise per week.
PCOS occurs when a woman does not release an egg regularly each month, causing her periods to be irregular. Women with PCOS can also have increased hair growth on the face and body, acne, head balding, infertility, pre-diabetes, and diabetes. PCOS is commonly treated with oral contraceptive pills (also known as the birth control pills). Sometimes, a medication called metformin is also used to treat PCOS, especially if a woman has evidence of insulin resistance or if fertility is desired. Unfortunately, metformin works in only some women with PCOS. The mechanism through which metformin works in PCOS is not clear and it difficult to predict who will benefit from metformin treatment and who will not. The investigators are doing this research study to look at how the medication metformin affects the cells in the body of patients with PCOS. Specifically, the investigators will look at how metformin affects the mitochondria. Mitochondria are the part of cells that produce fuel (energy) for other cells and play a role in metabolism. The investigators would like to see whether there is a relationship between mitochondrial activity and symptoms of polycystic ovary syndrome (PCOS) before and after treatment with metformin. They would also like to study whether genes affect the response to metformin in women with PCOS.
AMH is a member of the transforming growth factor family. It is produced by the granulosa cells from 36th weeks of pregnancy.Ovarian granulosa cells are the only source of the antimüllerian hormone. AMH production continues until response to exogenous FSH occurs and follicles reach 4-6 mm in diameter.The number of follicles in patients with polycystic ovaries are 2-6 times higher than normal women. Serum AMH levels are 2-3 times higher in patients with PCOS. The cause of elevated serum AMH levels in patients with PCOS is unknown. There are data showing elevated serum AMH level is due to the increase in the number of follicles 2-8 mm in diameter. Although there is no precise definition; multicystic ovarian is defined by the presence of more than six follicles 4-9 mm in diameter and mixed morphologically with PCO. PCO and multicystic ovaries are distinguished by the absence of the increase in stroma / volume.The aim of this study is to investigate whether there is a difference of serum AMH levels between patients with PCO or multicystic ovaries. A primary goal is to investigate the usability of AMH as a marker besides ultrasound for discrimination of nonhyperandrogenic patients with PCO or multicystic ovaries.
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of childbearing age. However, the optimal infertility treatment for PCOS patients is still a matter of controversy. Despite producing more follicles and more oocytes than other women undergoing controlled ovarian hyperstimulation during an IVF cycle, women with PCOS have comparable or lower pregnancy rates. Additionally women with PCOS patients undergoing IVF have a higher risk of developing ovarian hyperstimulation syndrome (OHSS), which may be aggravated by pregnancy after an embryo transfer in a fresh cycle. Further women with PCOS are thought to have higher rates of later pregnancy complications including spontaneous abortion, pre-eclampsia, and preterm labor that may be related to impaired implantation in the superovulated endometrium. We propose a randomized clinical trial of elective embryo cryopreservation followed by a programmed cycle of endometrial preparation and frozen embryo transfer (FET) compared to fresh embryo transfer in women with PCOS undergoing in vitro fertilization (IVF).
Women with PCOS have been observed to be potential diabetics.Recently,American Diabetes Association has suggested screening of women with PCOS for HbA1C.
The purpose of this study is to collect data to help understand why some women develop Polycystic Ovary Syndrome (PCOS) associated with decreased lower-body fat.
In obese women with polycystic ovary syndrome (PCOS), weight loss improves insulin resistance and hyperandrogenism, resulting in improvement of clinical symptoms. Weight loss is not required in lean PCOS patients; nevertheless, the influence of meal timing and composition on glucose metabolism and hyperandrogenism may have clinical value. In this study the investigators investigate the effects of two isocaloric diets with different meal timing distribution on insulin resistance and hyperandrogenism in lean PCOS patients.
The first aim of the investigators study, was to investigate the combined effect of diet,physical exercise and orlistat, for 24 weeks, on serum Anti-Müllerian Hormone (AMH) levels in obese women with polycystic ovary syndrome (PCOS) and in obese controls. The other aim of the investigators study, was to examine the effect of hypocaloric diet,physical exercise plus sibutramine on serum AMH levels, body composition, hormonal and metabolic parameters in overweight and obese patients with polycystic ovary syndrome (PCOS).
