ACOG's first-ever endometriosis guideline: Clinical impacts and why experts are split
Industry Buzz
The authors of these recommendations do not have a dedicated clinical or research focus in endometriosis … it is a complex, often surgical disease that requires advanced, subspecialty expertise. When that level of specialization is absent from guideline authorship, critical nuance can be lost.

Most physicians received limited formal training in endometriosis. For many, it occupied a few slides in medical school or residency, often framed as “pelvic pain + infertility + laparoscopy for diagnosis.”
Yet in the clinic, the reality is far messier. Patients in their teens, 20s, and 30s present with cyclical pain that disrupts work and school, dyspareunia that strains relationships, or infertility without a clear explanation. Increasingly, they arrive already asking about endometriosis—having read about it, seen it discussed on social media, or heard other patients’ stories.
That combination (rising patient awareness and historically limited clinician training) has created a familiar tension: suspicion without certainty.
Now, the American College of Obstetricians and Gynecologists (ACOG) has released its first clinical guidance focused specifically on diagnosing endometriosis, aiming to standardize how clinicians move from symptom recognition to action. []
What to know
Endometriosis affects roughly 1 in 10 reproductive-age individuals, yet the pathway from symptoms to diagnosis has been notoriously slow—often 4 to 11 years in the US before patients get an answer. [] []
That delay isn’t just an inconvenience; it has real consequences: worsening pain, deteriorating quality of life, increased healthcare costs, and potential impacts on fertility.
“Endometriosis pain can be incredibly burdensome for women and girls, and we know that on top of that pain, many patients experience understandable frustration due to delays in care and limited management options offered to them,” said ACOG President Steven J. Fleischman, MD, MBA, FACOG. []
Traditionally, diagnosis hinged on laparoscopy, but this approach has helped fuel long waits for definitive answers. ACOG has codified an evidence-based approach that supports clinical diagnosis, meaning doctors don’t have to default to surgical confirmation before starting treatment.
With this guidance:
A detailed symptom history and physical exam can be sufficient to presume endometriosis and begin management.
Imaging plays a structured role in evaluation and planning.
Adolescents and adults with suggestive features—cyclical pain, dyspareunia, chronic pelvic pain, or infertility—are explicitly included. []
This move aligns with broader shifts away from using laparoscopy solely to identify disease and toward using clinical and imaging criteria to act on it earlier.
However, as Melissa McHale, MD, endometriosis excision surgeon at Washington Endometriosis and Complex Surgery, points out in an Instagram Reel, “the authors of these recommendations do not have a dedicated clinical or research focus in endometriosis.” She continues, “Endometriosis is not routine pelvic pain. It is a complex, often surgical disease that requires advanced, subspecialty expertise. When that level of specialization is absent from guideline authorship, critical nuance can be lost.”
What does that mean for your clinic?
Rethinking the diagnostic timeline
For too long, both patients and clinicians have accepted a multiyear delay in diagnosis as “normal.” By elevating the role of clinical criteria and structured imaging, this guidance gives you a framework to believe what your patient reports earlier and start meaningful management sooner. []
Practical triage
In busy ambulatory settings, you don’t need to reserve referral for surgical specialists to tick a “gold standard” box. Assess symptoms, use point-of-care pelvic exams, and order first-line imaging thoughtfully—they’re now recognized components of a valid diagnostic strategy. []
Conversations with patients change
Instead of telling a patient with classical symptoms that they might need surgery to know for sure, you can explain that their clinical presentation itself is reason enough to begin therapeutic planning. That reduces uncertainty, strengthens trust, and can improve adherence to management plans.
Empowerment—and expectation—across specialties
Although this guidance originates with obstetrics and gynecology, its implications extend to primary care, adolescent medicine, pain management, and reproductive endocrinology. Early recognition and initial management can often start outside specialist referral pathways.
Equity and access goals
Diagnostic delay isn’t just a medical problem; it’s an access problem. By lowering the barriers of invasive surgical procedures for diagnosis, the guidance aims to make care more equitable, particularly for patients who face systemic hurdles to specialist care.
