Gay men with one or more gay brothers Volunteers for NIH Genetic Study of Sexual Orientation sought. Gay men with one or more gay brothers and their families are invited to participate in a study sponsored by the National Institutes of Health. We are doing DNA studies of each chromosome region, looking initially for regions where gay brothers tend to share the same genes. Our goal is to locate one or more genes which increase the probability of a man having same-sex orientation. Identification of such genes will give us important insight into the basis of normal variation in this important aspect of human behavior.
