(BBC) A contraceptive computer chip that can be controlled by remote control has been developed in Massachusetts.
The chip is implanted under a woman’s skin, releasing a small dose of levonorgestrel, a hormone.
This will happen every day for 16 years, but can be stopped at any time by using a wireless remote control.
The project has been backed by Bill Gates, and will be submitted for pre-clinical testing in the US next year – and possibly go on sale by 2018.
The device measures 20mm x 20mm x 7mm and will be “competitively priced”, its creators said.
