While contraceptives have come a long way to provide simple, effective protection from unwanted pregnancy, there are still many caveats including the need to take a daily pill and its inefficiency against preventing sexually transmitted diseases. To help ease some of these conflicts, a new form of contraception, the tenofovir levonorgesterel IVR has been developed. Similar to other contraceptive rings, the tenofovir levonorgesterel IVR releases small amounts of the contraceptive medicine into the body and can be worn continuously for up to 3 months. However, when contact is made with fluids, the ring also releases tenofovir– a chemical believed to kill the HIV virus before it can enter the body.
The ring is still in development, and human trials have yet to begin. There are concerns that the ring may lead to the body developing a resistance to tenofovir, so its effectiveness against preventing HIV over a long period of time is still unknown. However, the developers believe that the ring can provide simple, effective contraception to women in developing countries who do not have as much access to birth control.
