Postpartum insertion of intrauterine contraceptive devices (IUDs) performed while women are still in hospital has a number of advantages. Earlier reports, however, generally associated this procedure with high expulsion rates. Recent studies, on the other hand, have shown that if IUDs are inserted immediately (within 10 minutes) after placental delivery, it is safe and effective. In some experienced centers, fairly low expulsion rates are reported. In this paper the experiences with postplacental IUD insertions from international studies are reviewed, the lessons we have learned from these experiences summarized, and future research directions suggested.
