Search for the male pill still on

ORAL contraceptives are effective drugs, but can only be taken by women. Researchers have therefore studied if a hormonal contraceptive for men is feasible.

An effective contraceptive pill for men would need to cause a reversible azoospermia. The drugs which have been tried include androgens, progestogens and antagonists of gonadotropin-releasing hormone (GnRH).

A Cochrane review found 33 randomised trials which compared hormonal contraception with other methods.

As testosterone alone is relatively ineffective, most hormonal regimens used a combination of testosterone and a progestogen.
