Show Summary Details


This chapter reviews the different physical, functional, and behavioral characteristics that have been shown to be sexually differentiated in humans. The magnitude of these differences is highly variable. At the behavioral level in particular, the size of differences in statistical terms is small. It is in the sexual area that the largest differences between genders are observed. Sexual orientation and sexual identity are without a doubt the most sexually differentiated characteristics in humans. In the majority of the population (over 90%) there is indeed usually no overlap between the sexual orientation of men and women. Homosexuality in this context represents the absence of difference between sexes for “sexual orientation.”.
