How common is adenomyosis?

Adenomyosis is more common than many people are told. In women of reproductive age, it’s often estimated to affect roughly 20–35%—and we believe the true number is likely higher because symptoms can be nonspecific and definitive confirmation has historically required examining uterine tissue after surgery.

Prevalence also depends on who’s being studied and how adenomyosis is diagnosed. In groups of patients being evaluated for symptoms like heavy bleeding, painful periods, pelvic pain, or fertility challenges, adenomyosis is found much more often—sometimes on the order of “about one in three” or more. If your symptoms fit the pattern, exploring a focused evaluation with our team (often starting with high-quality ultrasound and, when needed, MRI) can help clarify whether adenomyosis may be contributing and what options make sense for your goals.
