Sexual dysfunction following proctocolectomy.

: 122 patients, 66 men and 56 women, operated upon by proctocolectomy were interviewed by means of a detailed questionaire regarding any significant change in sexual function. In the majority of the patients (70% of the men and 87% of the women) the sexual relationships were considered to be unchanged or even enhanced. Impaired function was reported by 19 men (29%) and seven women (12%). Male sexual dysfunction consisted of impotence and abolition of ejaculation. True impotence occurred in five men, all above 40 years of age, corresponding to an incidence of 25%. Loss of ejaculation occurred even in young people (about 7%) but was more common in elderly patients (15%). Female dysfunction consisted of dyspareunia and/or inability to achieve orgasm. On the basis of the present results it appears unlikely that impotence is caused by the operative trauma per se. On the other hand loss of ejaculation is probably due to injury of the presacral nerves. Postoperative impotence might probably be improved by medical information and encouragement. Particular precautions during operation might reduce ejaculatory disorders. Careful handling and proper treatment of the perineal wound might prevent scarring and stricture of the posterior aspect of the vulva, a condition that appears to be a common cause of dyspareunia.
