What this trial studies

This pilot study investigates the potential impact of using menstrual cups on the displacement of intrauterine devices (IUDs). The researchers hypothesize that the suction created during the insertion and removal of menstrual cups may lead to a 15% rate of IUD expulsion. By analyzing data on IUD displacement and menstrual cup use, the study aims to identify variables associated with this phenomenon. The findings could help healthcare providers offer better guidance to patients regarding the safe use of menstrual cups alongside IUDs.

Who should consider this trial

Good fit: Ideal candidates for this study are females aged 18-45 who currently have an FDA-approved IUD and are seeking IUD removal.

Not a fit: Patients with known sensitivities to silicone, active vaginal infections, or those who are pregnant will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved counseling for patients using IUDs and menstrual cups, potentially reducing the risk of unintended pregnancies.

How similar studies have performed: While limited data exists on this specific interaction, the study addresses a novel area of inquiry regarding IUD displacement and menstrual cup use.
