This is an original study giving an information about the association body mass index, polycystic ovary syndrome and betatrophin.
Introduction: Betatrophin is a protein hormone which has a significant role in glucose homeostasis and lipid metabolism. The aim of this study is to compare the levels of serum betatrophin in overweight and normal weight women with PCOS.
Material and Method: Thirty-five patients normal weight women with PCOS (BMI\<25) and 38 obese women with PCOS (BMI≥25) were included in this prospective, cross-sectional study. Patients were selected according to Rotterdam criteria. Serum betatrophin levels were studied by ELISA method and then compared between these two groups besides the following additional parameters as waist circumference/hip circumference ratio, fasting blood glucose, 75 g OGTT (oral glucose tolerance test) results and HOMA-IR levels.
Comparison of the Betatrohin serum marker of insulin resistance in normal weight and overweight women with polycystic ovary syndrome cases.

Exclusion criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
