New implant allows men to turn their fertility on and
off with the flick of a switch (inside the scrotum)
From vasectomies to the male
contraceptive pill, there have been many attempts to shift the burden of birth
control burden onto men.
Now one German entrepreneur believes
he has the solution - a 'switch' to stop sperm from reaching the penis.
The valve - which is implanted
internally - is designed to divert the flow of sperm back to the man's
testicles, making him temporarily infertile.
If he later decides he wants a wants
to become a father, he simply locates the implant in his scrotum and flicks the
switch back, allowing sperm to be ejaculated.
The 1.8cm device is inserted in the
scrotum with the recipient able to turn the device on and off to control
whether sperm is ejaculated
Clemens Bimek, the inventor, claims
the spermatic duct valve has the potential to 'change the world' by offering a
contraceptive that is as effective as a vasectomy - without being permanent.
Mr Bimek, a joiner who lives in
Berlin, had been watching a documentary on contraception when he had the
brainwave.
He is so far the only recipient of
the device - which he hopes to fund through €5 million of investment including crowd
funding - with a trial involving 25 men set to start early this year.
