Japanese researchers may have created the right formula to create a male birth control.

Researchers have found that Cyclosporine A and FK506, drugs that are given to organ transplant recipients to stop their body from rejecting the new organ, also suppresses the development and mobility of sperm by inhibiting an enzyme called calcineurin, reported by The Daily Beast.

A test run was create using male mice and female mice. Female mice had sex with "knockout" male mice, who were given the sperm suppressing drug and the female mice did not get pregnant.

"Considering these results in mice, sperm calcineurin may be a target for reversible and rapidly acting human male contraceptives."
