Endometrioma Surgery and AMH: The Double-Edged Sword

#397 ‒ Endometriosis and adenomyosis: diagnosis, fertility,… · Jun 22, 2026 Health & Fitness

Endometrioma cysts are pseudo-cysts tightly adhered to ovarian cortex where primordial follicles live. Strip them out and you can reduce AMH by 40 to 50%. Leave them in and the Fenton reaction destroys follicles through hydroxyl radical toxicity. The right move: harvest eggs first, then decide on surgery.

Clinical case example #3: Managing adenomyosis after failed IVF transfers to improve implantation and pregnancy outcomes

At 1:18:15 · chapter starts 1:10:09

The third case is a 32-year-old with frozen embryos and two failed transfers who arrives without a prior diagnosis of adenomyosis. Tomioka frames this as 'very common.' The mechanism of failure is not implantation per se but pregnancy maintenance: adenomyosis disrupts the junctional zone, triggering uterine contractions that expel the embryo between weeks 6 and 8. The fix is not surgical (adenomyomas aside, adenomyosis cannot be excised without a hysterectomy) but hormonal: 2 to 4 months of GnRH agonist treatment (Lupron, goserelin) creating chemical menopause, followed by a frozen embryo transfer using minimal estrogen and high progesterone. Published data show this approach meaningfully improves implantation and live birth rates while reducing miscarriage. The distinction between GnRH agonists (which cause an initial flare before downregulating the receptor) and the newer, more expensive oral antagonists (elagolix, relugolix — about $1,000/month) is explained; both work, but agonists have more data and are far cheaper in Brazil. Tomioka also discusses the broader pregnancy risks for women with adenomyosis: preterm birth, preeclampsia, small for gestational age, and elevated C-section rates — and that adenomyosis with junctional zone involvement carries a threefold higher miscarriage risk.

Adenomyosis and IVF: How to Turn 2 Failed Transfers Into a Live Birth

#397 ‒ Endometriosis and adenomyosis: diagnosis, fertility,… · Jun 22, 2026 Health & Fitness

Women with adenomyosis who fail repeated IVF transfers are often missing one key step: 2 to 4 months of GnRH agonist therapy before the embryo transfer. This chemically suppresses estrogen, quiets adenomyosis-driven uterine contractions, and meaningfully improves live birth rates.

The Worry Time Technique

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.

Glad You Did It Activities vs. Mindless Scrolling

Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.

Cognitive Restructuring: Training Your Second Thought

The Only 12 Lessons Buried In Every Self-Help Book - Spence… · Oct 10, 2026 Health & Fitness

You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
