Abstract:
Studies have indicated that same-sex orientation and behavior has a genetic basis and runs in families, yet specific genetic variants have not been isolated ( 1 ). Evidence that sexual orientation has a biological component could shape acceptance and legal protection: 4 to 10% of individuals report ever engaging in same-sex behavior in the United States, so this could affect a sizeable proportion of the population ( 2 ). On page 882 of this issue, Ganna et al. ( 3 ) report the largest study to date, comprising almost half a million individuals in the United Kingdom and United States, identifying genetic variants associated with same-sex sexual behavior. They provide evidence that genetic variation accounts for a small fraction of same-sex sexual behavior and uncover a relationship to the regulation of the sex hormones testosterone and estrogen as well as sex-specific differences. They also reveal complexity of human sexuality.
