Genetic and environmental influences on 2D:4D finger length ratios: a study of monozygotic and dizygotic male and female twins.

Archives of sexual behavior - 1 Feb 2008

Abstract excerpt

Recent studies have shown significant sex differences in the pattern of 2D:4D finger length ratios in humans and several other mammalian species. In humans, these ratios are suggested to be negatively correlated with prenatal exposure to testosterone, positively correlated with prenatal estrogen, and exhibit sex specific patterns of association with sexually dimorphic clinical phenotypes. However, the relative...
