The Sex Files
HOMOSEXUALITY
IN THIS EPISODE

Why are some people gay? That's the $64,000 question - at least in the scientific community. Is it something genetically predetermined? Or does environment have an impact on whether an individual turns out to be gay or lesbian? These questions are beginning to be probed in ways that might finally be leading to an answer, and the Sex Files has interviewed the foremost authorities on the topic to uncover some of those scientific clues:

Dr. Devendra Singh, University of Texas psychologist specializing in the evolutionary significance of human physical attractiveness

Dr. Ken Zucker, head of the Child and Adolescent Gender Identity Clinic at the University of Toronto's Clarke Institute of Psychiatry

Dr. Ray Blanchard, head of the Clinical Sexology program at the University of Toronto's Clarke Institute of Psychiatry

Dr. Michael Bailey, professor of psychology at Northwestern University in Illinois and specialist in the genetics and environment of sexual orientation

Dr. Marc Breedlove, professor of psychology* specialising in the sexual differentiation of the brain.

* The original episode guide described Dr. Breedlove as a "professor of psychology at UCLA." Dr. Breedlove noted in 2008 "I am not, and have never been, a professor of psychology or of anything else at UCLA." Breedlove earned his Ph.D. at UCLA but taught at UC Berkeley before taking an appointment at Michigan State.
