Abstract
First year results of a randomized study of 1509 users of the Copper T380Ag with a
silver core or of an IUD releasing 20 mcg day of levonorgestrel are reported. The
cumulative gross pregnancy rate for each device was 0.3 per 100 at one year, with
more than 490 women having one year of use with each device. The levonorgestrel-releasing
device was associated with significantly fewer bleeding days and significantly increased
hemoglobin levels when compared with pre-admission values or the one year values observed
among users of the TCu380Ag. Terminations attributable to amenorrhea were significantly
more frequent among users of the levonorgestrel — releasing device. The TCu 380Ag
was associated with increased frequency and severity of dysmenorrhea compared with
pre-admission levels or with the steroid-releasing device. Hemoglobin levels were
somewhat reduced among users of the TCu 380Ag device. Terminations attributable to
pain were, however, not significantly different by device. Continuation rates at the
end of the first year were not significantly different by device.
