[Experiences with vasectomy. Catamnestic study over a 10-year period].

Vasectomy can be a valuable contribution of the male to family planning. Vasectomy is a final method of contraception; it is not correct to make any hope for a later refertilisation because it is not sure that this operation will be successful. If a contraception is final, then it is not advisable to refer to methods of reconstruction or cryoconservation of sperm, because these methods are not always successful. Without intensive discussion with the couple and without sufficient time for the couple's decision, vasectomy can be very dangerous. Some specific examples are presented.
