Con to the question "Is Sexual Orientation Determined at Birth?"
"No-one has actually measured the levels of androgens in foetuses or the womb - you can imagine it is difficult to do - so this [the Nature article by Williams et al.] is all speculation. It may be informed speculation, but I think when we get on to a subject as touchy as sexual orientation we need to clearly define what is speculation and what is fact."
Key Experts MD's and PhD's in psychology, with significant post-doctorate involvement in human sexuality issues. [Note: Key Experts definition varies by sites that have this designation.]
