Could immune imbalance explain chronic pelvic pain?
NCT ID NCT07429773
First seen Jun 25, 2026 · Last updated Jul 28, 2026 · Updated 3 times
Summary
This study looks at the immune system of 120 women aged 18-40 with chronic pelvic pain that hasn't improved with hormone treatment. Researchers will measure specific immune markers in the blood to see if there is a unique pattern linked to the pain. The goal is to better understand the condition, not to test a new treatment.
