The digit ratio, or the relative lengths, of the 2nd and 4th digits (2D:4D) shows a sex difference, with males tending to have lower values in comparison with females…. This study aimed to estimate finger lengths and the 2D:4D ratios for the first time in Saudi Arabian subjects using direct and indirect measurements, and to evaluate the correlations between both indirect and direct 2D:4D with adult testosterone and various sexually dimorphic physical traits.
