Study Summary
This study is a randomized controlled trial comparing 6 month usage rates of the levonorgestrel-releasing intrauterine device (LNG-IUD) when inserted postplacentally after vaginal delivery or delayed placement at 6-8 weeks postpartum. Given the high rate of unintended pregnancy in the United States, particularly in postpartum women, there is a need for reliable, effective, long-term contraception such as the IUD in postpartum women. Postplacental insertion of intrauterine contraception would help to address this need. The primary hypothesis of this study is that use of the LNG-IUD at 6 months after vaginal delivery will be higher in women who have immediate postplacental insertion as compared to delayed insertion 6-8 weeks following delivery.
Primary Outcome
Usage rate of the LNG-IUD at 6 months after delivery
Interventions
- DEVICE Levonorgestrel-releasing IUD (Mirena)
