Kneem recently posted an article about this; here is the paper abstract: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=14559357&dopt=Abstract "...However, recent evidence indicates that gonadal hormones may not solely be responsible for sex differences in brain development and behavior between males and females...genes, by directly inducing sexually dimorphic patterns of neural development, can influence the sexual differences between male and female brains...The identification of genes differentially expressed between male and female brains prior to gonadal formation suggests that genetic factors may have roles in influencing brain sexual differentiation."
http://my.webmd.com/content/Article/75/89823.htm?printing=true "...Hormones do play a role, but hormones are not the whole story," Vilain tells WebMD. His study appears in the October issue of Molecular Brain Research. [the above abstract]...In fact, recent studies at UCLA have also shown that chromosomes affect behavior..." That last statement might explain why children with ambiguous genitalia but who are genetically male (having an X and a Y chromosome), and who were surgically (and at puberty, hormonally) made 'female' nevertheless felt "male." Certainly many geldings display stallion-like behavior and interests, despite having no testosterone for ~20 years.
