Objective To compare safety and efficacy among 3 types of intrauterine device (IUD), namely UCu200, TCu380A, and medicated γ‐IUD, when inserted after vacuum aspiration. Methods In a multicenter randomized comparative study, 1800 parous women requesting an IUD were enrolled in 12 centers across China in 2004–2005. The women received 1 of the 3 types of IUD and were followed‐up for 12 months. Results Among the participants, 596 received the UCu200, 591 received the TCu380A, and 594 received the medicated γ‐IUD. No pregnancy occurred during the follow‐up period. The expulsion rate was 4.13 per 100 women (95% confidence interval [CI], 0.83–5.75) for the UCu200, 5.16 (95% CI, 0.92–6.96) for the TCu380A, and 2.73 (95% CI, 0.67–4.05) for the medicated γ‐IUD. The rate of medical removal of the UCu200, TCu380A, and medicated γ‐IUD was 3.60 (95% CI, 0.77–5.11), 2.25 (95% CI, 0.62–3.46), and 1.02 (95% CI, 0.41–1.83), respectively. Conclusion Immediate insertion of the device after vacuum aspiration was found to be safe and effective for all 3 types of IUD. Compared with the other IUDs, the medicated γ‐IUD had a lower rate of medical removal and might be the most appropriate for broad use. www.chictr.org : ChiCTR‐TRC‐12002395
