Our Grant

MCI’s support helps Revolution Contraceptives advance Vasalgel toward human trials. The planned evaluations will be based on contraceptive effectiveness, procedural simplicity, reversibility, and safety. This proof-of-concept study will build on results from earlier preclinical studies and should support a future application for clinical trials in men.

Vasalgel is intended to be a long-acting, non-hormonal contraceptive with a significant advantage over vasectomy in that it is likely to be more reversible and have fewer side effects post-procedure. The procedure is similar to a no-scalpel vasectomy, except the vas deferens (the tube the sperm swim through) is injected with a hydrogel, rather than being cut as is done in vasectomy. If a man wishes to restore the flow of sperm, whether after months or years, he may receive an injection in the office setting that removes the hydrogel.
