title: Comparison of copper intrauterine device with levonorgestrel-bearing intrauterine system for post-abortion contraception.
abstract: OBJECTIVE
  The aim of this study was to compare the safety, bleeding pattern, effects, side-effects, complications and 6-month continuity rates of levonorgestrel-bearing intrauterine system (LNG-IUS) with conventional copper intrauterine device (Cu-IUD) inserted immediately after voluntary termination of pregnancy up to 10 weeks of gestation.
  
  
  METHODS
  One hundred women who underwent voluntary pregnancy termination and preferred IUD insertion as a contraceptive method after counseling were enrolled. The patients were randomly allocated to Cu-IUD or LNG-IUS and followed up at 10 days, and at 1, 3 and 6 months. The expulsion rates, continuation rates, side-effects, and bleeding patterns were compared.
  
  
  RESULTS
  Fifty women in the Cu-IUD group and 44 women in the LNG-IUS group were followed up. The continuity and expulsion rate for Cu-IUD and LNG-IUS at the end of 6 months was 74%, 12%, and 75%, 11.3%, respectively. In LNG-IUS users, the incidence of amenorrhea and the number of spotting days were higher and hemoglobin increased throughout the follow-up period. The side-effects related to both methods were not different from interval insertions.
  
  
  CONCLUSIONS
  Immediate post-abortion intrauterine contraception with Cu-IUD or LNG-IUS is a safe, reliable method. The incidence of side-effects is similar, and there is only a slightly higher rate of expulsion but an acceptable rate of method continuation.
