Abstract The TCu380Ag and the Cu‐7 intrauterine devices (IUDs) were evaluated in a randomized comparative clinical trial. A total of 198 women who had not recently been pregnant entered the trial in Manila, Philippines and were followed‐up through 3 years postinsertion. The 36‐month follow‐up rates were impressively high at 80.3 for TCu 380A users and 76.7 for users of the Cu‐7. Although the two IUDs demonstrated statistically similar termination rates, the findings suggest a higher efficacy for the TCu380Ag. Gross cumulative life‐table pregnancy rates were 0.0 and 4.5 for the TCu380Ag and Cu‐7, respectively, at 3 years. Overall 3‐year continuation rates were 74.3 and 64.9 for users of the respective devices.
