What the study is about

This study will provide pilot data examining suction as a mechanism of IUD displacement with menstrual cup use. The investigator hypothesize that manufacturer-recommended menstrual cup insertion and removal by breaking the seal will result in 15% rate of IUD displacement/expulsion. The investigator will also use this data to explore variables associated with IUD displacement and menstrual cup use. By examining the role of suction as a possible mechanism of IUD displacement, this research will allow healthcare providers to better counsel patients who use IUDs regarding menstrual cup use. Having a better understanding of the mechanics of IUD displacement could lead to the development of strategies to prevent expulsion.

Being studied: Menstrual Cup Removal
