Not Clearly Pro or Con to the question "Is Sexual Orientation Determined at Birth?"
"I would argue that there is evidence that sexual orientation in the male has a strong tendency to be affected by and at least partly induced by androgens prenatally (but there is no evidence that female sexual orientation is brought about prenatally). That said, homosexual males are also exposed to probably the same dose of androgens as heterosexual males. Thus, sexual orientation is too complex in its origins at present to understand."
