Vasagel works by blocking the sperms and is expected to be reversible through a second injection that dissolves the 'gel', which is a kind of polymer.
The Parsemus Foundation may soon change the contraception game for good. They are currently developing a non-hormonal form of male contraceptive called Vasagel. It would be the first approved male contraceptive method since the condom. Vasagel is essentially a gel that is injected into a man’s sperm-carrying tubes called vas deferens, accessible through the scrotum. This is done under local anesthesia. It works by blocking the sperms and is expected to be reversible through a second injection that dissolves the ’gel’, which is a kind of polymer.
One injection of Vasagel is expected to last up to ten years. If all goes according to plan, the contraception could be available for consumers by 2018.
