Abstract

Prenatal androgen exposure has suggested to be associated with lateral preferences in humans as per the Geschwind-Behan-Galaburda (GBG) theory, the Sexual Differentiation Hypothesis (SDH) and the Callosal Hypothesis (CH). The 2D:4D ratio is the putative marker of prenatal androgen exposure. The study aimed to determine the relationship between the 2D:4D ratio and lateral preferences.
