Abstract

Objective: Assess feasibility of randomizing women to intrauterine device (IUD) type.

Study design: Women enrolling in a 2-month study who desired an IUD for contraception were randomized 1:1 to receive a levonorgestrel-releasing 52-mg IUD (LNG-IUD) or copper T380A IUD (Cu-IUD), understanding they could switch IUD type at the end of the study.

Results: Randomization to IUD type was acceptable to 54/55 (98%) women who screened. All 32 enrolled participants completed follow-up. Two women exchanged their IUD (Cu-IUD to LNG-IUD), and two requested removal (one LNG-IUD, one Cu-IUD). Overall, 88% continued their assigned IUD.

Conclusions: Randomization to IUD type is feasible, and few women change their IUD.
