Contraceptive pill for males moves ‘a step closer’

A male Pill that provides a safe, effective and reversible method of contraception has been brought a step closer by scientists.

Researchers identified two proteins that can be blocked to prevent the “launch” of sperm cells from the testes during ejaculation.

Knocking out the proteins in genetically engineered mice resulted in male animals that were completely infertile, though they continued to mate normally.
