Menstrual cup use and intrauterine device expulsion in a copper intrauterine device randomized trial.

ABSTRACT:

Objective

To evaluate menstrual cup use and intrauterine device (IUD) expulsion.

Study design

We performed a secondary analysis of a 3-year contraceptive efficacy trial comparing two copper 380 mm² IUDs. Investigators randomized participants approximately 1:4 to the TCu380A or NTCu380-Mini IUD. Approximately 12 months after enrollment began, we advised participants against menstrual cup use due to observed IUD expulsions in cup users. We evaluated IUD expulsion (including spontaneous partial and complete expulsion and accidental self-removal) at 12 and 36 months. We used multivariable logistic regression to evaluate IUD expulsion by age, baseline menstrual volume, body mass index, IUD type, menstrual cup use, parity, and uterine length.
