Menstrual cups and IUDs: new study investigates suction risk
NCT ID NCT05254041
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether using a menstrual cup can pull an IUD out of place. Researchers will ask 80 women to insert and remove a menstrual cup the recommended way, then check if the IUD has moved. The goal is to understand how suction affects IUD position so doctors can give better advice to patients.
