Peter Attia MD397 - Endometriosis and adenomyosis: diagnosis, fertility, reproductive aging, & emerging treatments
At a glance
WHAT IT’S REALLY ABOUT
Endometriosis, Adenomyosis, Fertility Limits and Emerging Treatments Explained by Dr. Tomioka
- Tomioka describes endometriosis as endometrial-like tissue growing outside the uterus and adenomyosis as the same kind of tissue inside the uterine muscle, two distinct but overlapping diseases with estrogen dependence, progesterone resistance and tumor-like growth.
- Diagnosis is often delayed by roughly six to seven years because pain is normalized, no blood biomarker exists, and a regular ultrasound can miss disease, whereas specialized ultrasound with bowel prep or MRI can detect it well.
- Treatment depends on the patient's goals: hormonal suppression and an IUD or pill are typically first-line for pain, while surgery, IVF, and GnRH suppression before embryo transfer come into play when fertility is the aim.
- On fertility more broadly, Tomioka stresses that maternal age and egg aneuploidy are the dominant factors, that human reproduction is inefficient, and that egg freezing success follows a steep 'funnel' from follicles to live birth.
- He is optimistic about new ACOG guidance allowing empirical treatment and about a prolactin-receptor antibody for endometriosis, while calling mitochondrial replacement and stem-cell-derived eggs promising but not yet solutions.
IDEAS WORTH REMEMBERING
5 ideasModern reproductive patterns may be fueling more endometriosis
Tomioka says a modern woman has roughly fourfold more ovulatory cycles and retrograde menstruation than a woman 200 years ago, which he sees as a possible main driver of rising prevalence, alongside immune dysregulation and possible environmental factors.
A normal standard ultrasound does not rule out endometriosis
Standard ultrasound has very low sensitivity, so a detailed protocol with bowel prep or an MRI is needed, and Tomioka considers specialized ultrasound essential before planning surgery.
Delayed treatment can make pain harder to fix
Using a burglar-alarm analogy, Tomioka explains that years of untreated pain can cause central sensitization, which surgery and hormones don't fix and which requires pelvic floor physiotherapy and pain specialists.
Treatment choice hinges on whether the patient wants pregnancy
For pain without near-term pregnancy plans, hormonal suppression is tried first, but for a woman who wants to conceive, surgery is favored because medications are contraceptive and offer no lasting effect after stopping.
Adenomyosis can undermine IVF even with good embryos
Tomioka says contractions at the junctional zone cause losses around six to eight weeks, and months of GnRH agonist or antagonist suppression before frozen embryo transfer can raise implantation and live birth rates.
WORDS WORTH SAVING
5 quotesIt's like putting a 1,000 horsepower F1 engine into a golf cart, right? You just have the machinery, but you can't go further.
— Dr. Renato Tomioka
Imagine like endometriosis lesion is a burglar, right? So surgery can remove the burglar. Hormones can lock the door. But once you have this alarm system ringing and ringing years after years, the wiring changed, and now even a wind can, you know, triggers the alarm.

If you do a normal ultrasound and you don't have endometriosis in the report, doesn't mean that you don't have endometriosis.
— Dr. Renato Tomioka
It's like a battery swap for the egg, but you're not changing the engine, right? The engine is the main problem.
— Dr. Renato Tomioka
The cases that stay with me are not the most complex surgeries, not the difficult IVF cycles. They are those women that cry not from pain, but during the appointment from relief.
