Genetics of Sexual Orientation

The study aims to understand why some people are attracted to people of the same sex, while others are attracted to those of the opposite sex. The project studies which genes influence sexual attraction. We are currently collecting families in which there are at least 4 male members who identify as gay. Access to straight members of the same family is also important in order to compare genetic differences between gay and straight individuals within the same family. This project is being run by Drs. Eric Vilain and Tuck Ngun.
