Background Women who undergo a cesarean section (CS) are in a unique position to receive the intrauterine contraceptive device (IUD). They may also want to use the IUD as a long-acting reversible contraceptive method provided the IUD is safe and effective in the presence of a CS scar. Search strategy We researched and reviewed the MEDLINE, POPLINE, Google Scholar, and ClinicalTrials.gov databases from January 1968 to June 2015. Selection criteria Eligible studies reported event rates or practical problems relating to IUD usage in post-placental or interval insertion (>90 days) after CS. Studies with ≥20 subjects were included. Data collection and analysis Analysis of eligible data collected from the search followed the PRISMA guidelines. Main results Twelve eligible studies of post-placental IUD insertion after CS included four randomized controlled trials of post-placental versus delayed insertion. Women randomized to delayed insertion were less likely to receive a device. Six studies examined the problem of missing IUD threads at follow-up with only 30%–60% presence of strings observed. Conclusion The IUD is a long-acting reversible contraceptive method that is suitable for use in all women undergoing CS. The problems of device expulsion, missing threads at follow-up, and the tendency of increased puerperal bleeding need to be solved. Solutions are proposed.
