Welcome to the official website of the Bimek SLV,

the revolutionary spermatic duct valve,

which the internet has decided to call

Sperm Switch

Hello Internet!

It’s great to see you here!

Please find on this website all informations about the Bimek SLV, the revolutionary device by German inventor Clemens Bimek. In 20 years of research he developed this valve. This “switch” can easily be implanted into the vas deferens inside the scrotum to prevent sperm cells be part of the ejaculation. Once implanted you can open and close the valve from outside the scrotum easily and at any time.

The internet has decided to call the Bimek SLV just “sperm switch”.

This is partly true, you can switch it and open/close the sperm’s way up to be part of the ejaculate fluid. But after closing the switch, you have to wait to be really sterile at least 3-6 months.

The British tabloid Daily Mail was the first online medium that called the Bimek SLV sperm switch. From there it got viral, which is really great. So Ms Kate Pickles is to be honored for introducing the term sperm switch to the internet.
