Abstract

Sex differences have been reported in human morphological, physiological, and functional cerebral asymmetries. While several theories have specifically focused upon the relationship between prenatal testosterone and dimorphic patterns of laterality, activational influences of testosterone on cerebral lateralization are rarely discussed. In the present study, lateralization for face recognition and letter identification was examined in adult hypogonadal and control men. Hypogonadal men exhibited a decreased degree of asymmetry for face recognition but not letter performance compared to men with normal circulating concentrations of gonadal steroids. These results illustrate activational influences of testosterone on cerebral asymmetries.
