Molecular Genetic Study of Sexual Orientation


Join Us in Our Research



Researchers from the NorthShore University HealthSystem Research Institute, Northwestern University, University of Chicago, and University of Illinois at Chicago are searching for genes that influence male sexual orientation.

We are seeking families with two or more living gay brothers to assist us in our research. Participants are asked to provide a DNA sample (blood or saliva) and answer questionnaires. Participants will be reimbursed for time and any expenses associated with the study.
