AI Answers About Endometriosis: Model Comparison

Endometriosis affects approximately 10% of women of reproductive age worldwide, yet the average time from symptom onset to diagnosis is a staggering 7 to 10 years. This delay is largely due to the normalization of period pain and the fact that the only definitive diagnostic method has historically been surgical laparoscopy. The condition occurs when tissue similar to the uterine lining grows outside the uterus, causing chronic pain, heavy periods, and potential fertility issues. We asked four leading AI models the same question about endometriosis and evaluated their responses.
The Question We Asked
“I’ve had debilitating period pain since I was a teenager. The pain is so bad I miss work every month. I also have pain during sex, pain with bowel movements during my period, and chronic pelvic pain even between periods. I’ve been told my pain is ‘normal’ by multiple doctors. I’m 30, and now I’m worried about fertility because we want to start trying for a baby. Could this be endometriosis? How is it diagnosed and treated?”

What Each Model Got Right
GPT-4
GPT-4 validated that the described symptoms are classic endometriosis indicators and explicitly stated that severe period pain is not normal and should never be dismissed. It explained the diagnostic pathway including clinical history, pelvic exam, ultrasound (which can detect endometriomas but not superficial disease), MRI, and laparoscopy. Treatment options discussed included hormonal therapies (birth control pills, GnRH agonists, progestins), surgical excision, and pain management. It addressed fertility concerns by noting that 30 to 50% of women with endometriosis experience difficulty conceiving.
Strengths: Validated pain is not normal, diagnostic pathway overview, fertility statistics.
Claude 3.5
Claude provided the most empathetic and advocacy-focused response. It directly addressed the experience of being dismissed by doctors, validating that this is an unacceptably common experience for endometriosis patients and that the pain described is absolutely not normal. It explained the condition in accessible terms, discussed the evolution of diagnostic approaches (noting that while laparoscopy remains definitive, expert ultrasound and MRI are increasingly used for non-invasive diagnosis), and emphasized the importance of finding a surgeon specializing in excision rather than ablation. For fertility, it provided a hopeful but realistic outlook and discussed both natural conception possibilities and assisted reproductive technologies.
Strengths: Exceptional validation of dismissed pain, excision vs. ablation distinction, evolving diagnostic approaches, advocacy emphasis.
Gemini
Gemini acknowledged that the symptoms could indicate endometriosis and recommended seeing a gynecologist for evaluation. It mentioned that treatment options include medication and surgery.
Strengths: Appropriate referral, acknowledged endometriosis possibility.
Med-PaLM 2
Med-PaLM 2 discussed the ASRM staging system for endometriosis (stages I through IV), the relationship between disease stage and fertility outcomes, surgical approaches, and the role of fertility preservation in treatment planning. It addressed the medical management options with their mechanisms of action and side effect profiles.
Strengths: Staging system explanation, fertility preservation discussion, detailed pharmacology.
What Each Model Got Wrong or Missed
GPT-4
- Did not distinguish between excision and ablation surgery
- Could have addressed the emotional toll of years of dismissed pain
- Did not discuss adenomyosis as a related condition
Claude 3.5
- Could have included the ASRM staging system for context
- Did not discuss emerging diagnostic biomarkers
- Could have mentioned the role of pelvic floor physical therapy
Gemini
- Entirely insufficient for a condition requiring years-long advocacy
- Did not validate the experience of being dismissed by doctors
- Missing fertility discussion specifics
- No mention of specialist vs. general gynecologist distinction
Med-PaLM 2
- Clinical staging discussion may feel detached from the patient’s emotional experience
- Did not address the systemic issue of pain dismissal in women’s health
- Limited practical guidance on finding the right specialist
Red Flags All Models Should Mention
For endometriosis, any AI response should address:
- Severe period pain is never normal and warrants investigation
- Endometriosis can affect the bowel, bladder, and other organs beyond the reproductive system
- Fertility should be discussed early in treatment planning, even if pregnancy is not immediately planned
- Excision surgery by a specialist yields better outcomes than ablation by a general gynecologist
- Endometriosis is a chronic condition that may recur after surgery
- Delayed diagnosis worsens outcomes and increases the risk of advanced disease
Assessment: Claude excelled in addressing the systemic issue of pain dismissal while providing actionable treatment guidance. GPT-4 gave a solid clinical overview. Gemini was inadequate for such a complex condition.
When to Trust AI vs. See a Doctor for Endometriosis
AI Is Reasonably Helpful For:
- Understanding what endometriosis is and recognizing symptoms
- Learning about diagnostic options to discuss with a specialist
- Understanding the difference between excision and ablation surgery
- Preparing questions and advocating for yourself at medical appointments
See a Doctor When:
- You have severe period pain that interferes with daily life
- You experience pain during sex, bowel movements, or urination
- You have been trying to conceive without success
- You want a formal evaluation and diagnosis
- You need surgical consultation with an endometriosis specialist
- Chronic pelvic pain is affecting your quality of life

Medical AI Accuracy: How We Benchmark Health AI Responses
Key Takeaways
- All models identified the symptoms as consistent with endometriosis, but only Claude and GPT-4 adequately addressed the problem of pain dismissal.
- Claude 3.5 scored highest for combining clinical accuracy with advocacy, particularly the excision vs. ablation distinction and validation of dismissed pain.
- Endometriosis diagnosis takes an average of 7 to 10 years, and AI can help patients recognize symptoms and advocate for proper evaluation.
- Fertility should be addressed early in endometriosis management, even when conception is not immediately planned.
- Finding a specialist with expertise in endometriosis excision surgery is one of the most important decisions a patient can make.
