Levonorgestrel-releasing intrauterine device.
An intrauterine contraceptive device releasing 20 micrograms levonorgestrel daily has been studied for 15 years. The international clinical experience covers over 8000 woman years. Main characteristics of the levonorgestrel-releasing intrauterine device are its great effectiveness in preventing unplanned pregnancies and a reduction in menstrual bleeding and pain as well as a low infection rate.
