Request for evidence (cross-posted to fact_checking)

A friend of mine is in search of published research results suggesting a biological basis for homosexuality, and so far hasn't had much luck finding them amidst all the opinion articles and whatnot. Does anyone happen to know where some reasonably hard facts can be found?

Check out _The Science of Desire_; I'm pretty sure it has references to twin studies and the like.
