title: [Ambulatory vasectomy. Risks and complications].
abstract: Vasectomy is the simplest and most effective method of permanent sterilization in men. In most cases, the surgical technique includes conventional vasoresection with incision of the scrotal skin or no-scalpel vasectomy as a minimally invasive method. The most important complications following surgery are haemorrhage and haematoma (1.2%), infection (3.5%), epididymitis/epididymo-orchitis (2.1%), sperm granuloma (2-70%), and chronic pain (3-8%). No long-term negative organic effects have been proven in clinical studies. The surgeon's experience and the technique applied are essential for the postoperative course, whereas performing vasectomy either on an in-patient or out-patient basis does not seem to have an influence. To evaluate the success of the vasectomy, follow-up spermiograms are obligatory. If immotile spermatozoa are present further follow-ups are necessary. Vasectomy needs to be reperformed if motile spermatozoa are detected. The chance of an unsuccessful vasectomy is below 1%. Unprotected intercourse must not be performed before two consecutive spermiograms show azoospermia.
