RAPID EC - Rct Assessing Pregnancy With Intrauterine Devices for EC

Summary

This study is a randomized trial of two IUDs for emergency contraception: the copper IUD, the most effective method of emergency contraception vs. the levonorgestrel IUD, the most preferred IUD which has never been tested as an emergency contraceptive. This research has the potential to increase use of highly effective contraception in a high-risk population and lower the persistently elevated rate of U.S. unintended pregnancy.
