Contraceptive failure with Copper T380A intrauterine device (IUD): A single tertiary center experience.

Abstract

The objective of this study was to assess the risk factors of pregnancy with Copper (Cu)T380A IUD and pregnancy outcomes.A retrospective study evaluating the risk factors and pregnancy outcomes of 81 patients who conceived with CuT380A IUD .Four ectopic pregnancies and 77 intrauterine pregnancies were detected. Twenty-six pregnancies (33.76%, 26/77) were terminated according to maternal desire. Twenty-five patients (32.46%, 25/77) whose IUDs were removed constituted the Removed IUD Group, and the remaining 26 patients constituted IUD Left Group. Term pregnancy rates (76% vs. 20.8%, p=0.002) were significantly higher in the Removed IUD Group compared with the IUD Left Group. Abortion rates (16% vs. 53.84%, p=0.008) were detected significantly higher in the IUD Left Group.The main result of our study was that pregnancy with CuT380A is a significant risk factor for adverse perinatal outcome. Adjusting the scheduled follow-ups for checking the IUD seems to be important in order to prevent accidental pregnancy.
