An erratum to this article was published (J Clin Endocrinol Metab, 18 Dec 2024 ↗)
Authors' conclusion
We observed a 15.1% prevalence of PCOS in our medically unbiased population of premenopausal women. In this population of Siberian premenopausal women of Caucasian, Asian, and mixed ethnicity living in similar geographic and socioeconomic conditions, the prevalence was higher in Caucasian or mixed than Asian women. These data highlight the need to assess carefully ethnic-dependent differences in the frequency and clinical manifestation of PCOS.
