Filter by:Polycystic ovary syndrome (PCOS) affects 10% of all women, and it usually co-exists with high levels of sex hormones called androgens, such as testosterone. Women with PCOS are at increased risk of metabolic complications such as diabetes, non-alcoholic fatty liver disease, high blood pressure and heart disease. However, very little is understood about how androgen excess may drive the metabolic complications observed in women with PCOS. Skeletal muscle is an important site of energy metabolism; increasingly, it is suspected that skeletal muscle energy balance is adversely impacted by androgens, thereby driving metabolic complications. To take this theory forward, we want to investigate the effects of androgens on muscle energy metabolism. We will perform detailed metabolic testing (including blood tests and muscle biopsies) in women with PCOS before and after taking tablets that block the action of testosterone for 28 days. In addition, we will be using a gold standard technique to see how women with PCOS metabolise fat and other nutrients by measuring markers in blood and breath samples after a breakfast test meal. This clinical research will increase our understanding of the complex relationships between hormonal abnormalities and metabolic disease in women with PCOS.
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders occurring in women of reproductive age. PCOS is considered a syndrome of ovarian dysfunction that is characterized by the heterogeneous clinical manifestation of infrequent or absent menstrual cycles, hyperandrogenism, and polycystic ovarian morphology. An important ultrasound parameter is the ratio stroma/ovary, the ratio of the volume, evaluated in two-dimensional ultrasound, of the stroma, that secrete androgen, and the ovary. It has been shown that when this ratio is higher than a third the levels of circulating androgens and high. Aim of the present study is to assess whether this ratio, determined with three-dimensional ultrasound, is correlated to the increase of androgens.
Background: Infertility affects up to 15% of married couples. About half are attributable to female factors, among which anovulation is the leading cause. Some 5% of all women of reproductive age are anovulatory due to the polycystic ovarian syndrome (PCOS). PCOS causes also major health and cosmetic problems and significantly affects quality of life. PCOS is associated with cardiovascular morbidity and Type 2 diabetes mellitus, but it is unclear whether these are caused by the ovarian dysfunction or result from a common denominator. Working hypothesis and aims: Whole genome analysis of multigenerational families in which at least one woman is affected by PCOS may significantly reduce the numbers needed to verify the specific genes, involved in the causation of PCOS. Methods: Registration of multigenerational families and production of personal files with full workup for the presence of PCOS or its absence (in the women participants). Drawing of blood, extraction and preservation of DNA. Analysis of all informative SNPs in the genomes of the participants on a specific microarray chip. Statistical analysis of the results. Expected results: Verification of the loci and putative genes, associated with the appearance of PCOS. Importance: Elucidation of the specific genes underlying the pathology of PCOS. Probable implications to Medicine: Paving the way for targeted treatment of the problems, associated with PCOS, based on the clear knowledge of its underlying cause(s).
