Intrauterine Contraception

With its Ninth Progress Report the Population Council brought to a close a major phase of the Cooperative Statistical Program (CSP) for the Evaluation of Intrauterine Devices covering June 1963 through May 1968. In many countries the IUD is the primary method of contraception in national programs. From detailed data shown in 2 tables the following conclusions are drawn: No single type of IUD has consistently lower or higher rates than others for all types of complications. There is no consistent pattern of complications associated with tailed devices compared to tailless devices. The smaller sizes of all types of IUDs tend to have higher pregnancy and expulsion rates than the larger ones. Except for the spiral removals for medical reasons are not associated with the size of the IUD. Removals are the most important reason for discontinuing use of an IUD. 2 OF 3 devices are still in place 2 years after first insertion. Rates of continuation are the same for all major devices. The risks of pregnancy expulsion and removal for medical reasons are highest in the first year. The smaller sizes of loops are recommended for nulliparous women only. The pregnancy rate was lowest for the spiral highest for the steel ring and bow. Expulsion rates were lowest for the bow. The spiral had the highest expulstion rate and the highest rate of removals for medical reasons. Continuation rates over a 6-year period using Loop D show that 5 of each 10 women were still using the loop at the end of 4 years and 4 of 10 at the end of 6 years. A decline in complications was noted with increasing duration of use
