Abstract

The relevance of 2D:4D ratio to prenatal level of androgenization has been currently in the center of attention. The data on association between 2D:4D and testostosterone in adult males are highly inconsistent. In this paper we present the data on 2D:4D ratios on both hands, saliva testosterone and cortisol levels in the sample of 1545 boys (mean age: 13.49 ± 2.18 years) and 1716 girls (mean age: 13.56 ± 2.16 years) from three regions of Russia (Central, Volga-river and Northern Caucasus regions). Mean 2D:4D ratio differed significantly in boys and girls (0.97 and 0.98 respectively) on both hands. There was no correlation between 2D:4D and age with control for sex and the region of study. Both saliva testosterone and cortisol levels were higher in boys, compared to girls. The effects of the region and age were significant as well. No association between testosterone level and 2D:4D ratio were found for both sexes. We discuss our data in the light of previously publish data on testosterone and the digit ratio.
