This uld mean that there are some gen that are passed down om the mother’s si that make women more fertile and make men more likely to be gay. No matter why those gen are still around, we do know that beg gay is partly geic and partly termed before a baby is even born. It was, LeVay acknowledg, the perfect Frdian recipe for homosexualy-only he was nvced Frd had e and effect backward: hostile fathers didn't make sons gay; fathers turned hostile bee the sons were "unmascule" to beg year, LeVay, now a nroscientist at the Salk Instute La Jolla, Calif., got a chance to exame his hunch up close.

What he found is still reverberatg among scientists and may have a profound impact on how the rt of thk about homosexualy.

Two years ago he was reced for an amb study of homosexualy tws, unrtaken by psychologist Michael Bailey, of Northwtern Universy, and psychiatrist Richard Pillard, of the Boston Universy School of Medice.

Yet at least three rearch projects, one of them at the Natnal Instut of Health, are believed to be searchg for a "gay gene" or group of gen. In the nightmare scenar, once a gay fet is tected utero, is aborted, or a geic swch is "flipped" to ensure s heterosexualy.

LeVay has been able to field that one by potg out that he found no pathology suggtg such damage eher gay or straight men who died of the disease.
