Post-vasectomy erectile dysfunction.

We investigated two groups of men with regard to vasectomy acceptance, and subsequent erectile dysfunction. Group I was a group of 45 men chosen at random from 254 vasectomized patients. Group II was a group of 18 men who, out of 180 patients treated for erectile dysfunction, attributed their dysfunction to previous vasectomy. We analysed the social background, motivation for vasectomy and postoperative changes of sexual life or behaviour of the partners. The partnership constellation, particularly the role of a predominant female partner seems to be an important feature for vasectomy acceptance. Low acceptance might cause erectile dysfunction.
