I don't expect you to simply take my word for it though, especially since my recollection of the exact findings is so poor. I'll try and find a link, if I can ever figure out how to get the damn search function on the BBC website to work properly. I suppose they are isolated studies so not the be-all and end-all, but still interesting and consistent with what a lot of gay people will tell you when you tell them their sexuality is a "choice", in my experience.
Edit:
Here is a story from a few years ago about a supposed link, I think the study I'm thinking of is more recent though.
