Pelvic inflammatory disease (PID) is a bacterial infection of the female reproductive organs — the uterus, fallopian tubes, and ovaries — that affects approximately ~1 million women in the United States each year. Most cases are caused by sexually transmitted infections, primarily chlamydia and gonorrhea, though other bacteria can also be responsible. PID most commonly affects sexually active women between ages 15 and 25, and untreated PID is one of the leading preventable causes of infertility. The often subtle or mild symptom presentation means many women search online before seeking medical care. We asked four leading AI models the same question about PID to evaluate their responses.
The Question We Asked
“I’m 26 and for the past week I’ve had dull, aching pain in my lower abdomen, mostly on both sides. It’s worse during sex. I also have unusual vaginal discharge that’s yellowish-green with an odor, and some irregular bleeding between periods. I have mild fever. I was treated for chlamydia about a year ago. Could these symptoms be serious, and should I see a doctor right away?”

| Overall Score | 8.4/10 | 9.1/10 | 7.0/10 | 8.7/10 |
What Each Model Got Right
GPT-4
GPT-4 correctly identified the symptom pattern as highly suggestive of PID, connecting the previous chlamydia infection, bilateral lower abdominal pain, abnormal discharge, dyspareunia, and fever. It discussed the standard antibiotic treatment regimen covering chlamydia, gonorrhea, and anaerobes, emphasized partner treatment, and explained the risk of infertility from delayed treatment due to fallopian tube scarring.
Strengths: Strong STI connection reasoning, clear antibiotic treatment overview, important partner treatment emphasis, good fertility risk communication.
Claude 3.5
Claude provided the most thorough response, immediately emphasizing the need for prompt medical evaluation given the symptom constellation and STI history. It explained the ascending infection mechanism, the significance of each symptom, and the full spectrum of complications including tubo-ovarian abscess, chronic pelvic pain, ectopic pregnancy risk, and infertility. Claude discussed both outpatient and inpatient antibiotic regimens per CDC guidelines and emphasized the importance of STI screening for current partners and follow-up testing.
Strengths: Outstanding urgency communication, comprehensive complication discussion, excellent CDC-aligned treatment guidance, thorough partner notification discussion, strong follow-up testing emphasis.
Gemini
Gemini acknowledged that the symptoms warranted medical attention and recommended seeing a doctor. It mentioned that infections can sometimes cause these types of symptoms.
Strengths: Appropriate urgency, accessible language.
Med-PaLM 2
Med-PaLM 2 provided a clinically precise response discussing the diagnostic criteria for PID including cervical motion tenderness, adnexal tenderness, and uterine tenderness. It outlined the recommended CDC antibiotic regimens, discussed the threshold for hospitalization including tubo-ovarian abscess on imaging, and explained the long-term fertility implications with statistics on post-PID infertility rates.
Strengths: Excellent diagnostic criteria discussion, strong evidence-based treatment protocols, important hospitalization criteria, thorough fertility impact data.
What Each Model Got Wrong or Missed
GPT-4
- Did not discuss the threshold for when hospitalization is needed
- Limited coverage of long-term chronic pelvic pain as a PID sequela
- Could have addressed the emotional and psychological aspects of STI-related diagnoses
Claude 3.5
- Response length may delay a patient from seeking the urgent care recommended
- Could have been more concise about the most immediate action steps
- Did not discuss Fitz-Hugh-Curtis syndrome (perihepatitis) as a PID complication
Gemini
- Failed to identify PID as the likely diagnosis despite classic presentation
- Did not discuss STI testing or partner treatment
- Missing discussion of fertility implications
- No mention of specific treatment or the consequences of delayed care
Med-PaLM 2
- Clinical terminology such as “cervical motion tenderness” may not resonate with patients
- Limited discussion of the emotional support aspects of STI-related diagnoses
- Did not address stigma concerns that may prevent patients from seeking care
Red Flags All Models Should Mention
For pelvic inflammatory disease, any AI response should identify these concerns requiring urgent medical evaluation:
- High fever (above 101F/38.3C) with pelvic pain (possible tubo-ovarian abscess)
- Severe abdominal pain with nausea and vomiting
- Signs of peritonitis including rebound tenderness
- Inability to tolerate oral medications
- Suspected or confirmed pregnancy with PID symptoms (ectopic pregnancy risk)
- Failure to improve within 72 hours of outpatient antibiotic therapy
- History of recurrent PID episodes (cumulative fertility damage)
Assessment: Claude and Med-PaLM 2 provided the most clinically comprehensive responses. GPT-4 addressed core concerns well. Gemini was dangerously insufficient for a condition where treatment delays directly increase infertility risk.
When to Trust AI vs. See a Doctor for PID
AI Is Reasonably Helpful For:
- Understanding what PID is and how STIs can lead to it
- Learning about the importance of completing antibiotic courses
- Understanding why partner treatment and notification matter
- Preparing questions for gynecological appointments
See a Doctor When:
- You have pelvic pain with abnormal discharge, fever, or bleeding
- You have a history of STIs and develop new pelvic symptoms
- You need STI testing and antibiotic treatment
- Your symptoms are not improving after starting antibiotics
- You have severe pain, high fever, or cannot keep medications down (emergency)
- You have concerns about fertility after PID treatment
Can AI Replace Your Doctor? What the Research Says
Methodology
We submitted identical prompts to each model on the same date under default settings. Responses were evaluated by our team using the mdtalks.com evaluation framework, which weights factual accuracy (30%), safety (25%), completeness (20%), clarity (10%), source quality (10%), and appropriate hedging (5%).
Medical AI Accuracy: How We Benchmark Health AI Responses
Key Takeaways
- All four models recognized the need for medical attention, but only three specifically identified PID and its implications.
- Claude 3.5 scored highest for comprehensive complication awareness and actionable guidance including partner notification.
- The most critical finding: each episode of PID increases infertility risk, with approximately ~15% after one episode, ~35% after two, and ~75% after three, making prompt treatment essential.
- AI can help patients recognize PID symptoms and understand the urgency of treatment, but cannot replace the pelvic examination, STI testing, and antibiotic prescriptions needed for proper management.
- Women with pelvic pain, abnormal discharge, and STI history should seek same-day medical evaluation rather than waiting to see if symptoms resolve on their own.
