Female-to-male transsexualism, heterosexual type: two cases.

Two cases of gender-dysphoric genetic females who describe a sexual attraction to phenotypic males are reported. After outlining their individual histories, the authors note common clinical features of this subtype of transsexualism. Similar characteristics have also been found in the few cases of heterosexual transsexualism in genetic females reported by others. Familiarity with the distinguishing features of this subgroup could assist clinicians in diagnosing and treating such patients.
