Debra Son says "research suggests that men who are exposed to lower levels of prenatal androgens are more likely to be female-typical in their behaviour and sexually attracted to men". However, the paper she cites actually refers to rats and ferrets, not men. Not mentioning that is not good science. Also, in addition to genetic forces, there are undoubtedly cultural influences to many gender-related activities (for example, it is doubtful that the propensity to shave one's legs is genetically determined). It is therefore likely as wrong to attribute all gender differences to acculturation as it is to attribute them all to genetics. Either way, it is important to appreciate and respect the diversity of human expressions, and to avoid stereotyping.
