Vasectomy: benefits and risks.

Bilateral occlusion of the vas deferens, vasectomy, is progressively becoming the method of choice for couples seeking permanent contraception at a younger age, with smaller families. They are apparently well-informed and view the procedure as a natural step. Vasectomy is an inexpensively performed office procedure that causes minimal disruption of routine and has a high degree of community acceptance. The risks of significant hematoma, infection, discomfort and other sequelae are within acceptable limits. Improved techniques will continue to reduce the small failure rate. Antibodies observed in half of the patients have not been linked to systemic disease, although they are a hazard for the one patient in 500 returning for a vasovasostomy. Refinements in microsurgery and availability of artificial insemination enhance vasectomy as the method of choice. Evidently, extending the minimum time of sterility confirmation permits detection of occasional recanalization from technical failures. Adequate screening of the couple's motivation and expectations can prevent the rare psychologic disturbances, the greatest risk with this procedure and a problem associated with all options. For the male, there is no competitive technique at this time. In a world striving for equal rights, where the female still carries the burden of temporary contraception, the simplicity and popularity of vasectomy for permanent contraception add the desired undertones of social equilibrium.
