Summary

The risk of perforation from the use of intrauterine devices (IUDs) is low and similar for levonorgestrel-releasing (LNG) IUDs and copper IUDs. Compared with copper IUDs, however, LNG-IUDs were noted to have a significant reduction in the incidence of pregnancy, including a marked reduction in ectopic pregnancy. This article presents the results of the European Active Surveillance Study for Intrauterine Devices (EURAS-IUD; NCT0046/1175), a large, multinational, prospective, controlled, noninterventional study, conducted to compare the risk of perforation during and after insertion of 2 types of IUDs: LNG-IUDs and copper IUDs.
