Phenotype and Epidemiology of the Polycystic Ovary Syndrome (PCOS) in Colombia (PEP - Colombia) Study.

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: 1. 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? 2. 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.
