title: Contraceptive failure with Copper T380A intrauterine device (IUD): A single tertiary center experience.
abstract: OBJECTIVE
  The objective of this study was to assess the risk factors of pregnancy with Copper (Cu)T380A IUD and pregnancy outcomes.
  
  
  METHODS
  A retrospective study evaluating the risk factors and pregnancy outcomes of 81 patients who conceived with CuT380A IUDin situ.
  
  
  RESULTS
  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 Leftin situGroup. Term pregnancy rates (76% vs. 20.8%, p=0.002) were significantly higher in the Removed IUD Group compared with the IUD Leftin situGroup. Abortion rates (16% vs. 53.84%, p=0.008) were detected significantly higher in the IUD Leftin situGroup.
  
  
  CONCLUSIONS
  The main result of our study was that pregnancy with CuT380Ain situis 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.
