Gene May Yield 'Male Pill'

A newly identified gene that causes a type of male infertility may be the key to eventually developing a male oral contraceptive pill, the Independent reports. The gene, CATSPER1, enables sperm to wriggle through the outside of an unfertilized egg. A drug that could switch the gene on and off would cure infertility in some men and could allow for the creation of a male counterpart to the Pill, University of Iowa scientists said.
