If the female centre predominates in a male individual (due to an early lack of testosterone) then that individual will become homosexual. In a series of experiments on rats, Dörner showed that altering levels of various hormones at the critical times could indeed alter the morphology of these structures and create male ‘homosexual’ rats.
Quote:
Dörner et al., (1980) proposed that maternal stress is a key factor in the aetiology of male homosexuality as among males born in Germany between 1934 and 1953, an unusually high proportion of homosexuals were born during or immediately after the war (1941-1946). Dörner et al., (1983) also found that 75% of the mothers of homosexuals, compared to 10% of the mothers of heterosexuals were able to recall stressful episodes during pregnancy.
Ooh, and look at this site too. It's filled with interesting facts on homosexuality in animals. They researched homosexuality in over 470 species.
