'It is quite possible that there are several influences on forming a homosexual orientation,' said Gerulf Rieger, a sexual orientation researcher at Cornell University.

But as for why genetic factors would exist that make men gay, it appears that these genes make women, as well as gay men, alluring to other men.įollow Natalie Wolchover on Twitter nattyover.
