A comparative study of 4 copper IUDs, Cu T 200, Cu T 380, and Cu Y, was undertaken in the Peripheral Contraceptive Testing Unit of Indian Council of Medical Research at Madurai. 250 women wearing Cu T 200, 227 wearing Cu T 220, 281 Cu T 380 A and ll9 Cu Y were followed up at 1, 3, 6, 9, 12, and 18 months. Continuation rates were lower with Cu Y and Cu T 380. Expulsion and termination rates due to expulsion were higher with Cu T 200 and Cu T 380 A. Menstrual disorders were highest with Cu T 380A. There were 2 pregnancies with Cu T 200, none in the other groups. Expulsion rates were the lowest for Cu Y, Cu T 220 second lowest. Menstrual disorders occurred least among Cu T 200 users. Minor side effects, abdominal pain, backache, leucorrhea, did not vary with device used. The removal rate for menstrual side effects was highest for Cu T 380 A, 3x that of Cu T 200. Cu T 220 and Cu T 200 had similar removal rates. The Cu T 200 retains its contraceptive efficacy up to a period of 4 years.
