title: Two cases of abortion and premature birth after removal of a levonorgestrel-releasing intrauterine system.
abstract: Levonorgestrel-releasing intrauterine systems (IUSs) are frequently used for contraception, increasingly also in young women before and/or between planned pregnancy. We report on two cases of abortion (double abortion and abortion followed by premature birth) after removal of a levonorgestrel-releasing IUS. Both women (25 and 26 years old) with no previous gynecological problems had a normal pregnancy and had previously delivered healthy babies. The significance of the two cases remains unclear, unless further cases are reported. However, the authors believe that there is a need for further investigation of this issue.
