A follow-up study of 107 healthy males was conducted on average 4.7 years after vasectomy. Altogether 24 % of the subjects mentioned great satisfaction with the outcome of the surgical procedure; 74 % of the patients reported "general satisfaction", and only 2 % appeared dissatisfied with regard to the performed vasectomy. In no instance had postoperative psychiatric complications been observed. In 32 % of the patients the sexual potency was said to have improved after vasectomy, whereas 3 % reported impairment of sexual function following the operation.
