What makes someone gay

Short video description
By Andy Coghlan. We have known for decades that sexual orientation is partly heritable in men, thanks to studies of families in which some people are straight and some people are gay. Both findings were confirmed in a study of gay and straight brothers in For the first time, individual genes have been identified that may influence how sexual orientation develops in boys and men, both in the womb and during life. This enabled them to home in on two genes whose variants seem to be linked to sexual orientation.

Recently, scientists announced that they found some genes that might be associated with sexual orientation and a biological explanation for the reason gay men tend to have older brothers. But the field of sexual orientation research is far broader and more complicated than two studies—and Lisa Diamond , a psychologist and sexual orientation researcher at the University of Utah, knows that better than most. She spoke with Newsweek about what she and her colleagues in the field know—and what they don't—about how a person's sexual orientation might form. What do we actually know? How much of a person's sexual orientation can be chalked up to biology? Probably the strongest current evidence is for genetic contributions—but that doesn't mean we've found a gene.

The news this week that the largest study of its kind failed to confirm the existence of a "gay gene" is not so much a disappointment for those looking to understand the LGBTQ community, as it is an acknowledgement that science does not need to tell us what should be plainly obvious: gays, lesbians, bisexuals and pansexuals are who they are. What does he mean by "environmental"? This new research also reconfirms the long established understanding that there is no conclusive degree to which nature or nurture influence how a gay or lesbian person behaves.
