Dr. Blanchard is widely known for his typology of transexuals and as the originator of the term Autogynephilia, a controversial paraphilia which describes a heterosexual male's propensity to be sexually aroused by the idea of themselves as women. Dr. Blanchard was the psychologist in the Adult Gender Identity Clinic at the Clarke Institute of Psychiatry—now part of the CAMH (Centre for Addiction and Mental Health)—from 1980–1995. Much of his research in those 15 years concerned transsexualism and milder forms of gender identity disorders. In 1995, he was appointed Head of the newly created Clinical Sexology Services at the CAMH. This unit comprised the Adult Gender Identity Clinic. Since his retirement, he has continued to be active in research on human sexuality.
