Ultrasound-Guided IUD insertion after birth: does it prevent expulsion?
NCT ID NCT04474548
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using ultrasound to guide the placement of an IUD right after a vaginal delivery helps keep the IUD in place. About 100 women were randomly assigned to have the IUD inserted with or without ultrasound guidance. The goal was to see if ultrasound reduces the chance of the IUD falling out within 6-10 weeks. The study was stopped early, so the results are not complete.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrasound guidance
- What this could lead to
- If successful, this could show that using ultrasound during IUD insertion after childbirth lowers the chance of the IUD falling out.
- What could go wrong
- The study was terminated early, so results are limited. It was also small and only included women who delivered vaginally, so findings may not apply to everyone.
