• Study description:
  This study is an US postmarketing requirement that investigates the outcomes of uterine perforation and intrauterine device (IUD) expulsion in association with breastfeeding, postpartum exposures and type of IUD.The study aims to quantify the risk of uterine perforation and IUD expulsion in relation to the breastfeeding status and postpartum time (≤ 6, > 6 ≤ 14, > 14, ≤ 52 or > 52 weeks postpartum, including women without a recorded delivery within the past 52 weeks) at the time of IUD insertionThis study will also assess the risk of both perforation and expulsion by type of IUD. The effect of IUD types (LNG-releasing vs. copper) on the association between perforation/ expulsion and breastfeeding status/ postpartum status, as well as the effect of breastfeeding status on the association between perforation and/or expulsion and postpartum status are also investigated.
