We watched a video in psychology that proved that a mother's stress levels during pregnancy can lower the testosterone/estrogen levels of the babies, therby making homosexual babies. They did the study on several types of animals, but I only that they particularly said that rats do show homosexual behaviour as a result of this. I'm trying to find a site on it now...

Not to get off-topic, but the video also proved that homosexuality is not a choice as you cannot choose to lower your hormone levels. They did blood tests on several homosexual people and the results did show that they had low estrogen or testosterone levels.


Ahh here's a site I found. It's about the study that I was talking about.

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.
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.
