A new study in mice found an effective way to make sperm incapable of fertilizing an egg, quickly and reversibly.
The research was published Oct. 1 in the journal Science, and it looks like a promising development in the quest to develop a male contraceptive — an area in which condoms have long been the only option.
Of course, lots of studies find drugs that work great in mice but don’t work in humans. And the male birth control pill has been a bit of a pipe-dream for decades — many attempts, but nothing that’s made it to market.
