C-Section scar may impact IVF outcomes, new study investigates
NCT ID NCT04869007
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a defect in the uterine scar from a previous C-section (called an isthmocele) can lower the chance of getting pregnant with assisted reproduction like IVF. Researchers will measure the scar using a special ultrasound in 250 women before their IVF procedure. The goal is to see if women with a significant scar defect have lower pregnancy rates.
