title: Newer agents for hormonal contraception in the male.
abstract: Efforts to create a hormonal contraceptive for men use testosterone to suppress the production of pituitary gonadotropins and, hence, spermatogenesis. However, conventional testosterone must be administered by frequent injection, and when given alone, is not 100% effective. Therefore, newer androgens and agents that synergistically suppress gonadotropin production are being studied to create an effective and commercially viable contraceptive.
