Ultrasound angle may predict IUD displacement risk
NCT ID NCT05556421
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether the uterocervical angle (the angle between the uterus and cervix) measured by ultrasound can predict if a copper IUD will shift out of its correct position. Researchers studied 123 women aged 21-45 who had a T-Cu 380A IUD inserted. They compared the uterocervical angle in women with a displaced IUD versus those with a normally positioned IUD. The goal is to find a simple way to identify women at higher risk for IUD displacement before insertion.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify women at higher risk for IUD displacement before insertion, potentially reducing unplanned pregnancies.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. The findings may not apply to all IUD types or populations, and the angle measurement may not be reliable enough for routine use.
