Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This multicenter, institution-based, cross-sectional study evaluates the prevalence of polycystic ovary syndrome (PCOS) and PCOS phenotype in Eastern Siberia - the unique region of the Russian Federation with a multi-raced population living in similar geographic and socio-economic conditions for centuries. Therefore, the investigators considered this population optimal for epidemiological research.
