The article analyzes the data of anthropometric and somatotypological studies of 164 boys and 174 girls of the Khanty-Mansi Autonomous Okrug – Yugra, of diff erent sex somatotypes. It was found that 44% of boys and 15% of girls, according to sexual somatic diff erentiation, correspond to the biological sex, 40% of boys and 58% of girls have mild gender dysplasia in the form of mesomorphism, and 21% of boys and 27% of girls have signs of sex inversion. In young men from the northern region, clear sexual dimorphism anthropometric parameters were revealed. In girls of the Khanty-Mansi Autonomous Okrug – Yugra of diff erent sex somatotypes, no statistically signifi cant diff erences were found in most anthropometric parameters, which is associated with the general tendency of their somatic profi le to asthenization and masculinization
