Supravaginal uterine amputation vs. hysterectomy. Effects on libido and orgasm

Postoperative symptoms of hysterectomy have received relatively little attention. In the present study, the first author has personally interviewed and examined 105 abdominal hysterectomy patients and 107 patients with supravaginal uterine amputation preoperatively and 6 weeks, 6 months and 12 months postoperatively. Participation in the follow-up study was 99.5% (211/212) at one year. This paper deals with the effects of the two operations on libido and the frequency of orgasms. In the statistical analysis, McNemar's test of symmetry and the Fisher exact test were used. Weak or absent libido was reported preoperatively by 28.0% of hysterectomy patients and by 26.4% of amputation patients. One year postoperatively the corresponding figures were 35.4% and 31.4%. No statistical changes were observed between the two groups or within either group. In the frequency of orgasms a highly significant (p less than 0.001) reduction from the situation before operation to one year postoperatively was detected after hysterectomy. In the supravaginal amputation group no statistically significant decrease was detected. Preoperatively the two groups were alike; one year postoperatively the difference was almost significant (p less than 0.05). The reductions in orgasms after hysterectomy as compared with supravaginal amputation appears to result from the greater radicality of the former; at hysterectomy, the autonomous innervation of the proximal vagina and cervix is damaged more than in supravaginal amputation, the anatomy of the vagina is altered and scar tissue forms in the vagina. It is probable that these changes and subconscious psychological reactions due to total removal of the uterus explain why supravaginal uterine amputation gives better results than hysterectomy.
