'''Ray Blanchard''' is a psychologist and sexologist best known for his influential and often controversial research on sexual orientation, gender dysphoria, paraphilias, and patterns of sexual arousal. He spent much of his career at Toronto’s Centre for Addiction and Mental Health (CAMH), where he headed Clinical Sexology Services from 1995 to 2010, and is currently a status-only Full Professor of Psychiatry at the University of Toronto.

Blanchard is particularly associated with research on the fraternal birth order effect in male homosexuality and the maternal immune hypothesis proposed to explain it. He also introduced the term autogynephilia and developed a typology of male gender dysphoria based partly on sexual orientation and patterns of erotic arousal—a theory that has generated substantial scientific and public debate.

Blanchard also served as president of the International Academy of Sex Research and was a member of the DSM-5 Sexual and Gender Identity Disorders Work Group, including chairing its Paraphilias Subworkgroup.
