Apparent heterosexuality in two male patients requesting change-of-sex operation.

Abstract

Twenty-four male patients presenting with the request for change-of-sex surgery were studied. They were asked to estimate the strength of their sexual interest in men as compared with sexual interest in women. An independent and objective measure of sexual orientation was obtained by measuring penile volume responses to film sequences of male and female nudes. With two exceptions, the patients stated that their predominant or exclusive sexual interest was in males. The two patients who claimed to have no homosexual desires showed significantly more positive penile volume responses to female than to male nudes. The remaining 22 patients showed more positive penile volume responses to males. Brief case histories of the two apparently heterosexual patients are presented.
