After how many years the intrauterine contraceptive device, Cu-T 380A, should be replaced?
Cu-T 380A is composed of a stem wrapped with 314 mm2 of fine copper wire, and each arm has a 33-mm2 copper bracelet--the sum of these is 380 mm2 of copper. Two strings extend from the base of the stem. The Cu-T 380A is approved for 10 years of continuous use.
