4 New Male Contraceptives on the Way

So far there are only two birth control options for men: condoms and vasectomy. But stay tuned (in a few years) for some exciting new technologies.gt;gt;gt;1. Progestin shots plus testosterone creamgt; gt;At the 2007 Future of Male Contraception conference in Seattle, University of Washington researchers announced the results of a study involving progestin shots every three months combined with a daily testosterone gel. It worked well, but less than half of the men studied liked it.gt;gt;gt;2. Removable vasectomygt; gt;Also unveiled were the positive results of the first U.S. study of the "Intra Vas Device," a set of plugs that acts like a vasectomy but is removable. It has also been shown to have no effect on future fertility when used short-term in animals—more human studies are needed to gauge any long-term effects. gt;gt;gt;3. A pill for mengt; gt;Researchers at Columbia University announced that they'd found a nonhormonal drug that works as a contraceptive in mice. Will it work in men? Stay tuned. gt;gt;gt;4. Dry orgasmgt; gt;Another promising possibility: In 2006, researchers at Kings College, in London, announced that a couple of drugs for other conditions have the side effect of creating a "dry orgasm" in men. No semen, no sperm, no pregnancy. If a similar drug were developed for birth control use, it could be taken a few hours before having sex and be quickly reversible, with the effects wearing off after about 12 to 24 hours, researchers say.
