In humans, biological sex is determined by five factors present at birth: A child's presumed sex is determined at birth by observation of the external genitalia. Sex differences generally refer to traits that are sexually dimorphic. A subset of such differences is hypothesized to be a product of the evolutionary process of sexual selection. Sex differences in medicine include sex-specific diseases, which are diseases that occur only in people of one sex ; and sex-related diseases, which are diseases that are more usual to one sex, or which manifest differently in each sex.
