title: Recent advances in the pharmacologic regulation of fertility in men.
abstract: An updated review of research into contraceptives for men is presented. New concepts of the pharmacologic effects of chemical agents on germinal stem cells and spermatogenic arrest, and the effect of new compounds that act at the post-testicular level but do not affect androgen production are discussed. The latest results of studies on steroidal compounds that inhibit pituitary secretion of gonadotropin and hence result in suppression of spermatogenesis and testosterone secretion are presented. The newer contraceptive pills for men are also evaluated. The major drawback to the development of chemical contraceptives for men is the fear of genetic damage and impotence. New and continued research into this type of contraception is urgently needed.
