Study seeks best treatment for early pregnancy loss
NCT ID NCT07422506
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at different treatments for early missed abortion, where a pregnancy stops developing but the body doesn't expel the tissue. Researchers will compare surgery and medication, and also test if adding estrogen helps. The goal is to find the safest and most effective approach, with fewer complications like infection or scarring. About 580 women aged 18-40 will take part.
