We make contraception a man’s business

with the Bimek SLV, the spermatic duct valve from Clemens Bimek

One valve is mounted on each spermatic duct and disrupts the flow of sperm cells when closed. The user is then sterile, can wear the Bimek SLV for a life time and regulate it himself with just a flip of a switch. Taking any hormones or medication is unnecessary, for both men and women.

Before you can benefit from the fully-developed, internationally-patented spermatic duct valve, we need to show the Bimek SLV’s capabilities in a medical approval procedure. To do this we run technical tests with volunteer subjects. Since its invention and in moving forward we engage in absolutely no animal testing, making the Bimek SLV 100% vegan.
