Height of females with pure gonadal dysgenesis and normal male or female karyotype.

Cytogenetic studies and clinical investigations were performed in 44 cases of pure gonadal dysgenesis. The mean height of the females with the 46,XY karyotype was 6.6 cm higher than that of the females with the 46,XX karyotype. The greater difference found between normal males and females from the general population could therefore be related mainly to the hormonal influence of the testes during pre- and postnatal life.
