Short answer · Medically reviewed summary · Last updated: 2026-05-08
Asherman's Syndrome is an acquired condition characterized by the formation of intrauterine adhesions (scar tissue), typically following uterine surgery or trauma. While the exact prevalence remains unknown due to significant underdiagnosis, it is estimated to affect approximately 1.5% to 21% of women who undergo dilation and curettage (D&C) procedures, depending on the clinical context and diagnostic methods used. Is Asherman's Syndrome considered a rare disease? Asherman's Syndrome is categorized as a rare condition because it is often overlooked in clinical practice.
What is the prevalence of Asherman's Syndrome?
Prevalence of Asherman's Syndrome: how many people are affected worldwide, differences by sex and region, with sources.
Asherman's Syndrome is an acquired condition characterized by the formation of intrauterine adhesions (scar tissue), typically following uterine surgery or trauma.

Is Asherman's Syndrome considered a rare disease?
Asherman's Syndrome is categorized as a rare condition because it is often overlooked in clinical practice. Because it is an acquired, not congenital, condition, it exclusively affects individuals with a uterus. While the prevalence is relatively high among women with a history of post-pregnancy complications, Asherman's Syndrome is frequently underdiagnosed because many patients remain asymptomatic or are misdiagnosed with hormonal imbalances or other reproductive issues.
What factors influence the incidence of Asherman's Syndrome?
The incidence of Asherman's Syndrome is closely tied to the frequency of uterine interventions. Key factors impacting the development of this condition include:
- Post-partum curettage: The risk of developing Asherman's Syndrome is highest after a D&C performed shortly after childbirth or miscarriage.
- Infection: Chronic or acute endometritis can increase the likelihood of fibrotic adhesion formation.
- Diagnostic limitations: Hysteroscopy is the "gold standard" for diagnosis, yet it is not performed routinely, leading to a gap between actual and reported cases.
What is the geographic and demographic distribution?
Asherman's Syndrome does not show specific ethnic or geographic patterns, as its occurrence is primarily driven by medical procedures rather than genetic predisposition. It is strictly an adult-onset condition, as it requires prior uterine trauma. At DiseaseMaps.org, we have seen 39 people with Asherman's Syndrome join our community, providing a vital, real-world perspective on the diagnostic delays and recovery journeys that clinical literature often fails to capture.
Next steps
- Consult a reproductive endocrinologist or a gynecological surgeon specializing in hysteroscopic adhesiolysis.
- Request a hysteroscopy if you have a history of uterine trauma and are experiencing secondary amenorrhea or infertility.
