- •PCOS prevalence is similar in Europe and the USA, two areas with similar availability of gynaecological health services.
- •A major interest of this study was the analysis of four PCOS phenotypes frequency in countries of the same geographic area.
- •The prevalence of phenotype A, complete PCOS, was higher and that of C, ovulatory PCOS, was lower in the USA than in Europe.
