• Intrauterine device
• Expulsion
• Tampons
• Menstrual cups

Background: Many intrauterine device (IUD) users utilize intravaginal menstrual cups or tampons during menses, but no studies have investigated the impact this practice may have on IUD expulsions.
Study Design: Retrospective chart survey.
Results: Of the 930 women having IUDs placed and reporting menstrual protection, 10.3% (96) used menstrual cups, 74.2% (690) used tampons, and 43.2% (402) used pads (many women reported using more than one method). In the 743 women with adequate follow-up information, there was a full or partial expulsion (i.e., part of the IUD in the cervical canal) rate of 2.5% (27) during the first 6 weeks after insertion. There was no difference in the women using cups, tampons or pads (confidence intervals overlap).
Conclusions: From this study, there is no evidence that women who report using menstrual cups or tampons for menstrual protection had higher rates of early IUD expulsion.
