The risk of high-grade cervical neoplasms is lower in copper intrauterine device (IUD) users compared to levonorgestrel-releasing intrauterine system users, according to a retrospective study.

US researchers examined 10,674 women who received IUDs at their medical centre, with 8274 having copper devices while 2400 had hormone-releasing IUDs.
