Vasalgel, a multi-year contraceptive

VasalgelTM is a long-acting, nonhormonal contraceptive with a significant advantage over vasectomy: it is likely to be more reversible. The procedure is similar to a no-scalpel vasectomy, except a gel is injected into the vas deferens (the tube the sperm swim through), rather than cutting the vas (as is done in vasectomy). If a man wishes to restore flow of sperm, whether after months or years, the polymer is flushed out of the vas with another injection.

In early 2010, Parsemus Foundation began developing a new polymer contraceptive called Vasalgel™, and 12 months of rabbit studies have shown no sperm from the second semen sample onwards! Sperm flow quickly returned in rabbits that had the polymer flushed out 14 months later. A study in monkeys proved that Vasalgel was a successful contraceptive, with no pregnancies after 1-2 breeding seasons.

Vasalgel is being developed by the foundation as a “social venture,” a company that makes enough money to stay afloat but not to make anybody rich, with affordable pricing and wide availability as its mandate. The social venture company within the foundation is moving fast on getting the first steps done; however, it won’t have enough money to finish the project, and has conducted fundraising campaigns which have helped to support the preclinical studies that are paving the way for the first human trial.
