Uterine distension differences may shed light on infertility
NCT ID NCT07170137
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study is looking at how the uterus expands (distension) during a special ultrasound procedure in women who are having trouble getting pregnant and are undergoing IVF or ICSI. Researchers will compare these women to fertile women to see if there are differences. The goal is to better understand infertility, not to test a new treatment.
