Autogynephilia refers to a man’s sexual arousal at the thought of himself as a woman, and is considered a type of transsexual gender dysphoria. The term can be thought of in contrast to autoandrophilia, which refers to a woman's sexual arousal at the thought of being a man. There is a distinction within the classification of autogynephiliacs between heterosexual and homosexual desire.
Autogynephilia is also referred to as Blanchard’s transsexualism typology, or Blanchard’s autogynephilia theory (BAT).
