ABSTRACT
In the popular as well as the professional sexological literature there has been and continues to be uncertainty regarding the nomenclature and the classification of the different types of gender transposition or gender dysphoria. This uncertainty is especially evident with respect to the phenomenon of the person who has the anatomy and morphology of one sex, and who lives in socicty as one who has the gender identity and gender role—that is the gender-identity/role, or G-I/R (Money & Wiedeking, 1980)—of the other sex.
