A German carpenter Clemens Bimek has brought a revolution in the contraceptive world by claiming to invent an “on-off switch” that can control the flow of sperm from testicles.
The switch controls a valve that is implanted on the ducts which carry sperm from the testicles.
This valve measures an inch in length and weighs less than 0.1 ounces.
Bibek himself got the implant done under local anesthetic in a simple half-hour operation by his urologist.
Bibek told an English tabloid that he has been playing with his switch since it was installed and claims it works well enough that he’s convinced 25 other men to get the implants this year.
