BBC News: 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 hormone named levonorgestrel.

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.
