This fascinating dissection of the psychophysiology of eroticism in man is concluded in this article.1 The author found that orgasm can occur even after the removal of the clitoris (in a virilized hermaphrodite), the vulva, or the penis, as well as in the presence of impotence following chronic priapism. On the basis of case studies separating emission from orgasm, it is shown that the latter can occur without the former following prostatectomy and other surgery. Paraplegics can be stimulated locally to erection and ejaculation despite the loss of cerebral and cognitional participation. In summary, genitopelvic anatomy, the hormones, and the brain are three coördinates of sexual function, any one of which may fail in its contribution without total destruction of orgastic function.
