Let’s start with the number that should make every woman angry: nine years. That’s how long it takes, on average, for a woman with endometriosis to get a diagnosis. Nine years of being told her pain is normal. Nine years of missed work, missed school, missed intimacy. Nine years of adjusting her entire life around symptoms that a doctor should have taken seriously from the start.
That ends now. Or at least, it should.
In February 2026, ACOG released its first comprehensive clinical guidance on the diagnosis of endometriosis, and the most important thing in it is what they removed: the requirement for surgery.
For decades, the only way to officially diagnose endometriosis was to put a woman under general anesthesia, put a camera inside her abdomen, and look. No surgery, no diagnosis. No diagnosis, no treatment. That was the rule. Women were essentially being told, “prove it, or live with it.”
The new guidelines say that a clinical diagnosis, based on symptoms, a physical exam, and patient history, is now sufficient to begin treatment. You no longer have to go under the knife to get help.
What doctors should be looking for
Endometriosis should be suspected any time a patient presents with chronic pelvic pain, painful periods, pain with sex, painful urination, or painful bowel movements, whether those symptoms are cyclic or not. Transvaginal ultrasound is now the first line imaging tool, with MRI reserved for cases where we need more detail before planning treatment. And here’s something critical, a negative ultrasound does not rule out endometriosis. Superficial lesions don’t always show up on imaging. If the symptoms are there, treatment should be on the table. Full stop.
The guidelines also officially put CA-125 to rest as a diagnostic tool. It never had the accuracy to justify its use, and it’s out.
Why the diagnostic delay was never acceptable
This disease affects at least 11% of American women, more than 6.5 million people. Up to 80% of them live with chronic, debilitating pelvic pain. Nearly 68% miss work or school regularly because of it. And up to 50% of women dealing with infertility have endometriosis as an underlying cause. The longer we wait to diagnose, the more damage accumulates to the reproductive organs. Every year of delay is a year of disease progression we could have interrupted.
The mental health toll is staggering too. Research shows that 42% of women with endometriosis have clinically significant depression, and 51% have anxiety, both directly tied to pain severity and inflammation. We weren’t just undertreating a gynecologic condition. We were leaving women to develop mental health crises we could have prevented. Because if it’s predictable, it’s preventable.
What this means for fertility
Earlier diagnosis means earlier intervention, which means better preservation of reproductive function. For women who want to conceive, that window matters enormously. The damage endometriosis does to the tubes, ovaries, and surrounding tissue is cumulative. Every year without treatment is a year of harm we didn’t have to allow.
What I want every woman to know right now
If you have been living with painful periods, chronic pelvic pain, pain with sex, or bowel and bladder symptoms that flare with your cycle, you do not have to accept that as normal. You are allowed to tell your doctor you’re aware of the new ACOG guidelines. You are allowed to say that a clinical diagnosis is now sufficient to begin treatment, and that you are not willing to wait years for a surgery to prove what your body has been telling you all along.
And if your doctor dismisses you anyway? Find a new one!
One honest caveat
The guidelines are a significant step forward, but not everyone in the surgical community is celebrating without reservation. Some endometriosis excision specialists have raised legitimate concerns that moving toward empiric medical management, without surgical staging, could leave some women on treatments that manage symptoms without addressing the underlying disease. That debate is real, and it deserves attention. A clinical diagnosis is the right starting point. But for women with moderate to severe disease, especially those with fertility goals, a conversation about surgical evaluation may still be warranted. This is not one size fits all medicine. It never was.
