Applicants for sex reassignment can be placed on a spectrum of gender role identity transposition, as judged by the criteria of both duration and intensity of the sex-change conviction. In some patients, male-female ambivalence alternates in a kind of Jekyll-Hyde dissociation until the fourth or fifth decde of life, at which time it changes into a unitary compulsion to undergo a sex reassignment, and which first must be resolved if reassignment is to be successful. The transportation of gender role identity seen in transexualism relates to the two schemas, identification and complementation, by which gender role identity becomes established developmentally. Other degrees and manifestations of transposition can be categorized in a 2 X 3 table as either total or partial, and as either chronic, episodic, or elective.
