How to Choose an Endometriosis Specialist: Training, Six Checks, Red Flags and What to Ask

Why the word "specialist" tells you so little

Board certification in the United States is run by the American Board of Medical Specialties and its member boards, and the ABMS describes it as a higher standard than a medical license alone. The American Board of Obstetrics and Gynecology issues six subspecialty certificates: complex family planning, critical care medicine, gynecologic oncology, maternal-fetal medicine, reproductive endocrinology and infertility, and urogynecology and reconstructive pelvic surgery. None is named endometriosis, minimally invasive surgery or pelvic pain.

So a gynecologist with a residency and nothing more can use the words, and so can a surgeon who has spent a career on it. The checks below are how you tell them apart.

The training routes behind the title

After medical school, every gynecologist completes a residency in obstetrics and gynecology and can then sit the board exams. The amount of complex excision surgery a resident performs varies widely between programs.

Some go on to a fellowship. The AAGL Complex Benign Gynecology Fellowship (formerly the Fellowship in Minimally Invasive Gynecologic Surgery) is taken after residency and concentrates on advanced laparoscopic and robotic surgery for benign disease, including endometriosis. AAGL has been seeking formal subspecialty recognition for it; at the time of writing it is not an ABMS certificate. Urogynecology and reconstructive pelvic surgery is an ABMS subspecialty focused on pelvic floor and bladder conditions, not an endometriosis fellowship. A small number of pelvic pain fellowships exist; none is an ABMS subspecialty.

None of these routes is a guarantee, and the absence of a fellowship is not a disqualifier. Training tells you where someone started. The checks below tell you where they are now.

Check 1: excision experience

Volume matters, and so does what happens when the disease is deep. Deep endometriosis in the bowel, bladder or ureter cannot be treated by burning the surface, and the ESHRE 2022 guideline recommends it be managed in centers with the expertise and the team to excise it. Our guide to excision versus ablation explains the difference.

Ask

• How many endometriosis operations do you perform a year, and how many involve deep disease?
• Do you excise lesions, ablate them, or both? What decides it?
• If you find bowel, bladder or ureter disease, do you treat it at the same operation, and with whom?

Check 2: clinical diagnosis, not surgery first

The ESHRE 2022 guideline and NICE NG73 both support a clinical diagnosis of endometriosis from history, examination and imaging, with treatment started on that basis. A specialist should not insist on a diagnostic laparoscopy before offering any care, and should not dismiss you because a scan was normal. Our guide to how endometriosis is diagnosed sets out the steps.

Ask

• Do you make a clinical diagnosis, or only after surgery?
• If my ultrasound is normal, what does that rule out and what does it not?

Check 3: pelvic nerve and pelvic floor care

Pain often continues after lesions are removed. The ACOG practice bulletin on chronic pelvic pain describes how muscles, nerves, bladder and bowel each contribute to pain and recommends assessing them rather than treating the pelvis as one organ. See our guides to pelvic nerve pain and pelvic floor dysfunction.

Ask

• Do you examine the pelvic floor muscles and the pelvic nerves at the first visit?
• Do you work with a pelvic floor physical therapist and a pain specialist?

Check 4: imaging read by experienced hands

A transvaginal ultrasound reported as "normal" by someone who was not looking for endometriosis is a common reason for delay.

Ask

• Who performs and reads your ultrasounds, and do they use a dedicated endometriosis protocol that checks the bowel and bladder?
• When do you order an MRI, and who reads it?

Check 5: a team around the surgeon

NICE NG73 describes specialist endometriosis services as multidisciplinary, with gynecologists trained in advanced laparoscopy, colorectal and urologic surgeons, pain management and fertility services.

Ask

• Which colorectal and urologic surgeons do you operate with, and how often?
• Who manages my pain medication, hormones and physical therapy between visits?

Check 6: time and follow-up

A full endometriosis history cannot be taken in ten minutes. A good plan says what you are trying, how long to give it, and what the next step is if it does not work.

Ask

• How long is the first visit, and will I see you or another clinician?
• How will we judge whether treatment is working, and when do we review it?

Red flags

• A promise of cure. Endometriosis can recur after surgery, and no honest surgeon guarantees otherwise.
• Pressure to operate at the first visit, without a history, an examination and imaging.
• No pathology. Removed tissue should go to a pathologist, and you should see the report.
• No team. A surgeon who never operates with a colorectal or urologic colleague may not be seeing or treating deep disease; ask.
• Hostility to second opinions, or to questions about volume and complication rates.

Referrals, insurance and second opinions in plain terms

A referral is a written order from your primary care doctor for you to see a specialist. HealthCare.gov notes that many HMO plans require one before they will pay for care from anyone other than your primary care doctor, and that an HMO generally will not cover out-of-network care except in an emergency. Before the first visit, call your insurer with the doctor's name and ask three things: are they in network, do I need a referral, and does surgery need prior authorization.

Many experienced endometriosis surgeons are out of network. If so, ask the office for a written estimate and ask your insurer about a single-case agreement or a gap exception when no in-network surgeon treats deep disease.

A second opinion before surgery is normal and most surgeons expect it. Ask the first office for your records, imaging and operative reports, and tell the second doctor plainly that you are seeking another view.

What to bring to the first visit

A 90-day symptom record changes the visit. Note daily pain out of 10, period days, bowel and bladder symptoms, pain with sex, what you took and whether it helped, and days you missed work. Bring previous imaging, operative and pathology reports, every hormonal treatment you have tried, and your questions written down. The free PelviQuest app records daily symptoms, periods and medications and turns them into a report your doctor can read; it is a screening and tracking aid, not a diagnosis.

When you are ready to look, our specialist directory lists the academic centers in every state and the checks above in short form. Pages for New Jersey and New York show where you can book one of the physicians who offer booking through PelviQuest for in-person or video visits. PelviQuest does not rank doctors, does not show ratings, and takes no payment for listings.
