A “Molecular Condom” Could Be the Future of Male Contraception


"In a paper published last week in PNAS, researchers at UC Berkley have revealed a new possibility for male contraception: disabling the sperm cell from developing sufficient energy to puncture the wall of the egg.


This is done by obstructing CatSper, the ion channels that allows calcium to flow into sperm and give it a ‘power kick’. CatSper open when the sperm enters a cloud of progesterone close to the ovum, which triggers the sperm tail to change their movement from waggling (for swimming to the egg) to drilling (to penetrate it)..."
