Turn Off Sperm with an Implantable Light Switch

Device enables men to switch from sterile to fertile via manual actuation.



With the Bimek SLV, the spermatic duct valve from Clemens Bimek, the flow of sperm is “switched off” via a manual actuation of an implanted device. A 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 lifetime, and regulate it himself with just a flip of a switch. Taking any hormones or medication is unnecessary for both men and women. The company is currently seeking participants for human trials.
