Discovery of Gene May Lead to New Male Contraceptive

discovery of a key gene involved in sperm development could eventually lead to the creation of a new type of non-hormonal birth control for men, a study involving mice suggests.
Researchers found that a gene called Katnal1 is critical to enable sperm to mature in the testes. Finding a way to regulate this gene could prevent sperm from maturing, making them incapable of fertilizing eggs.
This finding also could lead to new treatments for cases of male infertility in which the Katnal1 gene
