Scientists have finally discovered a compound that may enable men to take a birth control pill.

In the US, researchers have been placing lab experiments were male mice were given a pill which rendered them infertile during the treatment as they produced fewer and less mobile sperm.

However creators insist that the male pill does not affect the hormone system or sex drive on those taking the drugs.

“There is no effect on the mouse’s mojo. The animals exhibit the normal sexual behaviours and frequency of copulation,” said Dr. James Bradner.

There is no permanent side effects from the drug, with the tested mice being able to still have healthy litters.

The male pill was discovered unintentionally, after scientists were trying to create a drug which was originally tested as part of a broader cancer research project.
