Status Details

Developer: Parsemus Foundation, University of Bari, University of California, University of North Carolina at Chapel Hill

Project Phase: Pre-Clinical and Clinical Development

Development Stage: Pre-clinical

Began discovery in: 1970s

Active Development: No

Status Details:
  • Already tested in multiple species for efficacy, toxicology, and genotoxicity. The method provides permanent sterilization in rats and dogs, but transient contraception in monkeys. Obtaining a long-lasting effect in humans has not yet been found.
  • Initial work on this method was conducted in the 1970s at the University of Missouri at Columbia. In 2010, researchers at UNC-Chapel Hill won a grant to study the method in rats. Parsemus Foundation is funding an Italian team who worked on dogs and a team at the University of California who worked on monkeys.
