T Gen and Homosexual Men: A Question

Geraldo Rivera has been advertising T Gen on his radio show for a while now. So, here's my question: could T Gen--since "testosterone is what makes a man, a man"--help make some homosexual men (that is, those born with homosexuality as a thorn in the flesh) heterosexual? As far as I know (or at least as I'm sure), boosting the testosterone levels--or at least countering the unusually-high or otherwise-irregular levels of estrogen and other (for a lack of better term) female hormones--has been used. Therefore, why not try an experiment with some homosexual men to see if giving them T Gen makes them--or at least causes them to become more--heterosexual? Of course, the men would have to consent to being part of the experiment--we don't want to get into eugenics or any other unethical science here.
