Remote Control Contraceptive

A new contraceptive implant that may be turned on and off using a remote control is scheduled to begin pre-clinical testing sometime next year. In addition to being more convenient, the new device is designed to last for up to 16 years – which for most women is nearly half their reproductive life.

Measuring about 20mm x 20mm x 7mm, the device can be implanted under the skin on the upper arm, abdomen or buttocks. Sixteen years-worth of levonorgestrel – a contraceptive hormone already in use – is stored on a microchip in tiny reservoirs that are covered with a membrane made of titanium and platinum. When activated, an internal battery passes an electric current through the membrane, causing it to melt temporarily and allowing a small dose of the hormone to diffuse into the tissue. When a woman is ready to conceive, she simply turns off the implant with the remote control. It can be switched back on again just as easily, and a doctor can adjust dosages remotely if needed.

The company plans to begin marketing the new implant sometime in 2018, pending the outcome of clinical trials.
