Short answer · Medically reviewed summary · Last updated: 2026-04-07
The prevalence of adenomyosis is estimated to range widely from 5% to 70% in symptomatic populations, though the exact global prevalence remains difficult to determine due to significant challenges in clinical diagnosis. Understanding Prevalence and Incidence Because adenomyosis is historically diagnosed definitively only through histopathological examination of a hysterectomy specimen, true population-based incidence and prevalence data are limited. While some studies suggest it affects approximately 20% to 30% of women of reproductive age, these figures vary based on the diagnostic criteria used—such as transvaginal ultrasound, MRI, or pathology.

What is the prevalence of Adenomyosis?
Prevalence of Adenomyosis: how many people are affected worldwide, differences by sex and region, with sources.
The prevalence of adenomyosis is estimated to range widely from 5% to 70% in symptomatic populations, though the exact global prevalence remains difficult to determine due to significant challenges in clinical diagnosis.
Understanding Prevalence and Incidence
Because adenomyosis is historically diagnosed definitively only through histopathological examination of a hysterectomy specimen, true population-based incidence and prevalence data are limited. While some studies suggest it affects approximately 20% to 30% of women of reproductive age, these figures vary based on the diagnostic criteria used—such as transvaginal ultrasound, MRI, or pathology. Unlike many rare conditions, adenomyosis is increasingly recognized as a common, albeit underdiagnosed, gynecological condition rather than a rare disease.
Demographics and Diagnostic Challenges
Adenomyosis occurs exclusively in individuals with a uterus, primarily manifesting during the reproductive years, with a peak incidence typically reported between ages 40 and 50. While research does not currently show definitive global ethnic disparities, variations in reporting often reflect differences in access to specialized imaging and gynecological care. The primary hurdle in establishing accurate statistics is that many individuals are asymptomatic or misdiagnosed with conditions like endometriosis or uterine fibroids, leading to a significant gap between clinical presentation and confirmed diagnosis.
Real-World Perspectives
At DiseaseMaps.org, our community of 412 individuals living with adenomyosis highlights the personal burden of this diagnostic delay. These real-world reports underscore that while clinical literature struggles to capture the exact number of cases, the lived experience of adenomyosis involves chronic, often debilitating symptoms that require greater clinical attention and improved non-invasive diagnostic tools.
