Contraception. 2019 Jul;100(1):85-87. doi: 10.1016/j.contraception.2019.03.047. Epub 2019 Apr 11.


Although reproductive-aged women use both menstrual cups and intrauterine devices (IUDs) simultaneously, it is unknown whether concomitant use reduces contraceptive effectiveness. We report seven cases wherein IUD expulsion occurred during concomitant menstrual cup use. Further research is needed to determine mechanisms of expulsion, predictors and strategies to avoid expulsions.
