Successful male contraceptive gel trial brings new form of birth control closer

A male contraceptive gel has been found to work reliably in a trial in primates, bringing the prospect of an alternative form of birth control for humans closer. The product, called Vasalgel, is designed to be a reversible and less invasive form of vasectomy and in the latest study was 100% effective at preventing conception. A blob of the gel is injected into the sperm-carrying tube, known as the vas deferens, and acts as a long-lasting barrier.
