Clinical experience with the copper 7 intrauterine device.
This paper reports further observations on our previous study of 203 Copper 7 intrauterine insertions performed in 199 women. There have now been accumulated 3799 woman-months of use. At least a 2-year period of observation has been attained from first insertion until these data were analyzed. The Copper 7 intrauterine device (IUD) continues to be an acceptable contraceptive method with regard to effectiveness, continuation, and lack of serious complications. Those patients who elected to have their copper 7 IUDs removed for planned pregnancy were also analyzed with regard to fertility capacity. Possible complications with the need to change the copper 7 IUD and risk of prolonged use were not verified. There was a decrease in contraceptive effectiveness after 12 more months' use.
