[Contraception for the man].

Current possibilities of contraception that can be practiced by the male continue to be based on the barrier concept. Methods that have an action on the spermatozoa, whether toxic, immunologic or hormonal have not become established in Germany, although the latter is still being researched, and even practiced (gestagen implant), in some countries. The two barrier methods--the condom and vasectomy--both have a permanent place in contraception: the condom is by far the more popular of the two, additionally providing protection against infection and free of side effects. The invasive procedure of vasectomy is not widely practiced, although, on the basis of risk-benefit considerations, it is the method of choice vis-à-vis the pill when a couple definitively want no more children.
