Abstract
The growth of world population and its impact on the environment and economy, especially in the developing countries, has brought about the need for family planning assistance available to everyone. Health organisations and pharmaceutical companies are aware of their responsibility in this respect and provide financial and logistic support to research in new methods of contraception.
Over the last 10 years, clear proofs have been established that exogenous administration of sexual steroids is an efficient and reversible contraception method through inhibition of spermatogenesis. The results of some non-hormonal approaches to male contraception have been surprisingly promising and may become a basis for the development of new methods of male contraception.
However, none of the 50 far published methods of contraception is 100% effeetive and applicable to all men in the world population with the guarantee of full reversibility of induced infertility. Vasectomy thus continues to be the only safe and reliable method.
