By Dave Smith (International Business Times) A promising new birth control treatment — for men, not women — looks to be the future of contraception. It’s safe, relatively uninvasive, 100 percent effective, and completely reversible. Developed by Prof. Sujoy K. Guha of the Indian Institute of Technology, the procedure called “Reversible Inhibition of Sperm Under Guidance,” or RISUG, is currently in advanced clinical trials in India. Researchers hope to get Vasalgel (or “RISUG” in the Indian trials) on the market as a common alternative to vasectomy as early as 2015.
In this new procedure, a doctor would inject a polymer gel called “Vasalgel” directly into the vas deferens instead of cutting it, which coats the walls of the duct and kills sperm as they go by. Should the man want to reverse the treatment for any reason at all, the procedure can be reversed simply by flushing out the Vasalgel with another injection of DMSO, a compound that is used in the medical treatment of many conditions and that is bioacceptable in the small quantities necessary.
