[Vasectomy : Current information].

Vasectomy is considered to be the simplest, most effective and cheapest method of fertility control in men, with a significantly lower risk of morbidity and mortality compared to tubal ligation in women. Patient informed consent is particularly important and should include potential irreversibility, surgical options, anesthesia, possible complications as well as postoperative behavior and the need for re-evaluation. There are different access routes available with conventional and no-scalpel vasectomy as well as different techniques for closing the ends of the vas deferens. To confirm sterility the European Association of Urology (EAU) recommends that an ejaculate analysis should be performed 3 months after the procedure and after approximately 20 ejaculations. Complications are relatively rare, although particularly vasectomy failure due to recanalization has to be considered. Approximately 3-6% of vasectomized men strive for a refertilization, which with experienced surgeons is successful in about 90% of cases.
