OMGA Copper


This item has been moved to

According to Russel J. Thomsen M.D., some 15 models of the OMGA Copper IUD were manufactured by Sodermec. The surface of the IUD was impregnated with acetate and nitrate salts of copper. The cervical threads (not present here) would have been attached through the eyelet at the base (cervical end) of the device. The device's shape somewhat mimics the shape of the uterus. The device was marketed and used through the 1960s to 1980s.
