‘Vasectomies could be a thing of the past thanks to a remotecontrolled implant that can stop the flow of sperm.
The valve-like device can be opened and shut at the press of a button, using the same technology that locks a car using a key fob.
Scientists who invented the implant say it could be used as a form of male contraception.
Men who change their minds about having children would then simply point the remote handset at their testicles and press a button to open up the valve. [..]
Once the handset is pressed, it sends a coded radio signal through the skin to the implant, which contains a tiny antenna. The antenna picks up the signal and converts it into sound waves that “ripple” through the valve.
Since the valve itself is soft and flexible, the sound waves make it flap open – allowing sperm to pass through. As with cars, each device would have its own unique code so it could not be opened by anyone else.’
