The new intrauterine contraceptive devices: safe and effective.

Reviews of the safety of intrauterine contraception usually are based on studies that do not reflect changes in clinical practice that have occurred over time, and that include many types of IUDs that are no longer used. Studies of insertions of the Multiload 375 and Copper T 380 performed since 1980, which more accurately reflect current clinical practice, show that these IUDs provide a high level of protection against pregnancy and are associated with low rates of complications. Current clinical opinion regarding the safety of IUDs needs to be reassessed in light of the positive safety record of these IUDs.
