Cystectomy can reduce AMH by 40–50%
Removing endometrioma cysts surgically can reduce ovarian reserve (measured by AMH) by 40 to 50% because follicles adjacent to the cyst wall are stripped away.

Clinical case example #3: Managing adenomyosis after failed IVF transfers to improve implantation and pregnancy outcomes
At 1:19:15 · 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. [1] — Renato Tomioka "Adenomyosis reduces IVF success by ~30%: Adenomyosis reduces the chances of successful IVF by approximately 30%, with junctional zone invol…" 1:17:00 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. [2] — Renato Tomioka "GnRH agonist treatment before embryo transfer: Two to four months of GnRH agonist (e.g., Lupron) therapy before embryo transfer in women wi…" 1:11:35 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
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.
GnRH agonist treatment before embryo transfer
Two to four months of GnRH agonist (e.g., Lupron) therapy before embryo transfer in women with adenomyosis significantly improves implantation and live birth rates while reducing miscarriage.
Adenomyosis reduces IVF success by ~30%
Adenomyosis reduces the chances of successful IVF by approximately 30%, with junctional zone involvement tripling miscarriage risk.
Endometrioma Surgery and AMH: The Double-Edged Sword
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.
