Blanchard's transsexualism typology
Blanchard's transsexualism typology is a psychological typology of male-to-female (MtF) transsexualism created by Ray Blanchard through the 1980s and 1990s, building on the work of his colleague, Kurt Freund. Blanchard divided trans women into two different groups: homosexual transsexuals, whom Blanchard says seek sex reassignment surgery to romantically and sexually attract (ideally heterosexual) men, and "autogynephilic transsexuals" who purportedly are sexually aroused at the idea of having a female body. The typology suggests distinctions between MtF transsexuals, but does not speculate on the causes of transsexualism. The distinction is a recurring theme in scholarly literature on transsexualism.
