We've heard plenty about the male contraceptive pill over the years, but it's still not on the market. There's a clear scientific reason.
Creating an effective male pill is no simple task. Women ovulate roughly once a month—no egg, no pregnancy. Men, however, produce up to 1,000 sperm per second, meaning millions must be suppressed daily to prevent conception reliably.
This holds true regardless of whether we'd fully entrust contraception to men.
