A safe, affordable, reliable, reversible male contraceptive has been one of medicine's holy grails. Now, clinical trials currently underway are pointing to a viable solution.
RISUG (Reversible Inhibition of Sperm Under Guidance) is just such a contraceptive. Instead of using hormones, RISUG uses a surgically implanted gel to stop the flow of sperm. Inserting RISUG involves a 10-15 minute procedure, and the birth control effect can last for up to 10 years, or until the gel is flushed out.
Clinical trials in India show that RISUG is safe and effective. Tests on men in North America, though, won't begin for several more years, and FDA approval would not occur until several years after that.
