If you’ve been following Vasalgel for some time, you already know that this new, long-acting contraceptive worked well in rabbits. But now it’s official!
Vasalgel contraceptive produced rapid azoospermia in rabbits. This graph illustrates the sperm concentration during baseline and after implantation in 12 rabbits. Eleven of the rabbits had no sperm concentration during any measurement after implantation, while one rabbit had very low levels in a few samples.
Parsemus Foundation policy is to only publish in open-access journals so the results are available to all, so you can read the paper for free here.
Next: Another publication, and full speed ahead
Reversal was also successful in rabbits, and that paper is next (it’s being prepared for publication). Meanwhile, despite the challenges with reversal in larger animals, we’re moving full speed ahead towards first clinical trial (initially as a vasectomy alternative while reversal issues are being sorted out).
Parsemus Foundation has created a social venture, Revolution Contraceptives LLC, to lead Vasalgel through the expensive development process, and is seeking socially-minded investors and partners committed to affordable access.
