A male contraceptive is closer than ever thanks to the development of a 'game changer' drug by scientists. The experimental drug which has been tested on mice can stop sperm swimming for up to two-and-a-half hours and has so far shown no side effects.
The non-hormonal drug, which has been two years in the making, is being developed by close friends and pharmacology professors Dr Lonny Levin and Jochen Buck and their teams at Weill Cornell Medicine.
The pair did not originally set out to find a male contraceptive drug, but thanks to the work of a colleague they discovered a way to stop sperm in it's 'tracks' by switching off a particular cellular signalling protein called soluble adenylyl cyclase (sAC).
