New study investigates why some women with adenomyosis suffer more pain
NCT ID NCT07455721
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the nervous system may become overly sensitive (central sensitization) in women with adenomyosis, a condition where uterine tissue grows into the muscle wall. Researchers will follow 1,200 women aged 18-50 for 12 months to see how common this sensitivity is and whether it affects pain and treatment success. The goal is to better understand pain patterns and improve care.
