Active clinical trials for "Hyperandrogenism"

The objective was to check whether serum androgen levels and concomitant metabolic changes, oxidative stress and inflammation in adolescent girls with hyperandrogenism may be related to diet. to identify the factors that increase the risk of being overweight and of obesity among adolescents with clinical features of PCOS, related to diet and DEA (Disordered Eating Attitudes) to investigate the relationships between markers of oxidation and markers of Systemic Inflammation and macronutrients intake to assess the relation between oral health of girls with PCOS (including condition of periodontium and dental caries) and their dietary habits, hormonal, metabolic and oxidative and inflammatory status.

The goal of this observational study is to know the prevalence of PCOS among economically productive and reproductive age women from Medellín and the Valle de Aburrá, Colombia. The main questions it aims to answer are: What is the phenotypic distribution of PCOS detected in women seeking medical attention as a requirement for employment in Medellín and the Valle de Aburrá, Colombia? What is the effect of environmental factors, such as geographical location and diet, and biological factors (such as obesity and ethnicity/race) on the prevalence and phenotype of PCOS in this populatión? Participants will undergo anthropometric measurements and physical examination for hirsutism, acne, alopecia, acanthosis nigricans, and thyroid enlargement. During the initial visit, a transvaginal or transabdominal pelvic ultrasonography will be performed. A sample of venous blood will be collected in plain tubes for serum cryopreservation and for immediate glucose estimation. Some participants will be rescheduled for a second evaluation visit for additional assessment when they have a possible PCOs.

Androgen excess is the cardinal biochemical feature of polycystic ovary syndrome (PCOS), a lifelong metabolic disorder affecting 10% of women. Serum testosterone correlates with insulin resistance in women, however, there is an urgent need to improve our understanding of the association between androgens and the risk of type 2 diabetes. Recently, a new subclass of androgenic steroids known as 11-oxygenated androgens has been identified. Utilising highly sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) techniques, our group has recently demonstrated that 11-oxygenated steroids are the predominant androgens in both health controls and women with PCOS, and that these correlate closely with markers of insulin resistance. The bioactive 11-oxygenated androgen 11-ketotestosterone (11KT) binds and activates the androgen receptor with equal affinity to testosterone, yet nothing is known about its impact on metabolism or glucose homeostasis. Intriguingly, unlike testosterone, 11-oxygenated androgens do not decline with age in women, and, therefore, may mediate an increased risk of T2DM in women across their life course. Therefore, this previously ignored androgen class is likely of major importance in female metabolic health, and may represent a novel metabolic risk factor and biomarker. However, 11-oxygenated androgens are not currently measured in routine clinical practice. To date, no population-based or human in vivo physiology studies have examined the association between 11-oxygenated androgens, glucose metabolism and diabetes risk in women, despite the high prevalence of PCOS in the female population. There is emerging evidence, even in women without a confirmed history of PCOS, that the levels of androgens over time correlate with their likelihood of developing metabolic and cardiovascular disease. This has not been studied to date in a prospective manner in healthy women in the background population using long term follow up data.

The investigators aim to estimate the prevalence of functional ovarian hyperandrogenism [idiopathic hyperandrogenism, idiopatic hirsutism, and polycystic ovary syndrome (PCOS)] in adult patients with type 1 diabetes (T1DM) in an observational cross-sectional study. Study population is comprised of premenopausal adult women with a diagnosis of T1DM, consecutively recruited from a Diabetes outpatient clinic at a tertiary hospital in Spain, Europe.

The purpose of this study is to determine if, in mid- to late pubertal girls with hyperandrogenism (HA), androgen-receptor blockade (spironolactone) alone normalizes sleep-wake luteinizing hormone (LH) pulse frequency (primary endpoint) and overall LH and follicle-stimulating hormone secretion (secondary endpoints).

Polycystic ovary syndrome (PCOS) affects 10% of all women and usually presents with irregular menstrual periods and difficulties conceiving. However, PCOS is also a lifelong metabolic disorder and affected women have an increased risk of type 2 diabetes, high blood pressure, and heart disease. Increased blood levels of male hormones, also termed androgens, are found in most PCOS patients. Androgen excess appears to impair the ability of the body to respond to the sugar-regulating hormone insulin (=insulin resistance). The investigator has found that fat tissue of PCOS patients overproduces androgens and that this can result in a build-up of toxic fat, which increases insulin resistance and could cause liver damage. In a large cohort of women registered in a GP database, the study team have found that androgen excess increases the risk of fatty liver disease. The aim is to identify those women with PCOS who are at the highest risk of developing metabolic disease, which would allow for early detection and potentially prevention of type 2 diabetes, high blood pressure, fatty liver and cardiovascular disease. The investigator will assess clinical presentation, androgen production and metabolic function in women with PCOS to use similarities and differences in these parameters for the identification of subsets (=clusters) of women who are at the highest risk of metabolic disease. The investigator will do this by using a standardised set of questions to scope PCOS-related signs and symptoms and the patient's medical history and measure body composition and blood pressure. This standardised recording of a patient's clinical presentation (=clinical phenotype) is called Phenome analysis. The investigator will collect blood and urine samples for the systematic measurement of steroid hormones including a very detailed androgen profile (=steroid metabolome analysis) and of thousands of substances produced by human metabolism (=global metabolome analysis). Phenome and metabolome data will then undergo integrated computational analysis for the detection of clusters predictive of metabolic risk.

Ovulatory dysfunction affects 18 to 25% of infertile women, the most common identifiable condition is polycystic ovarian syndrome (PCOS). The most frequent symptoms of PCOS are oligo-anovulation, hyperandrogenism and polycystic ovary appearance. Hyperandrogenism is the main contributor that affects oocyte and embryo quality and decreases the success rates in PCOS patients undergoing IVF treatments. The aim of this study is to determine the effect of hyperandrogenism as an independent factor on IVF success rates and oocyte/embryo quality in PCOS patients undergoing IVF.

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.

This mixed cohort study will test the frequency of PCOS among young females presenting with one of the clinical hyperandrogenism criteria: acne, hirsutism and/or hair loss. Diagnosis will be based on the recent PCOS clinical, biochemical and biophysical criteria recently published " International evidence-based guideline for the assessment and management of polycystic ovary syndrome (PCOS) 2018".

Hormones are substances that are made by the body and are sent directly out into the bloodstream to increase or decrease the function of certain organs, glands, or other hormones. Testosterone is a hormone found in the blood of all girls, but some girls have too much testosterone in their blood. Too much testosterone in the blood can possibly lead to a problem called polycystic ovary syndrome (PCOS). People with PCOS have abnormal menstrual periods, excess facial and body hair, and too much testosterone in their blood. On the other hand, some girls with too much testosterone in their blood do not develop PCOS. We do not know why some of these girls develop PCOS and why some do not. The purpose of this research study is to find out whether too much testosterone can cause problems with other hormones that can lead to the development of PCOS. This study may help us understand more about the causes of PCOS.
