It looks like men are going to get their own hormonal birth control. The article says:
The clinical trial, which begins in April and will run for about four years, will be the largest effort in the U.S. to test a hormonal form of birth control for men. The new gel contains two synthetic hormones, progestin and testosterone. Progestin blocks the testes from making enough testosterone to produce normal levels of sperm. The replacement testosterone is needed to counteract the hormone imbalances the progestin causes but won't make the body produce sperm. More than 400 couples will participate in the study, which will take place at sites in the U.S., the U.K., Italy, Sweden, Chile, and Kenya. Men in the trial will take home a pump bottle of the gel and rub about half a teaspoon of it on their upper arms and shoulders every day. The gel dries within a minute.
