Research to discuss with clinic

Peer-reviewed studies relevant to my IVF protocol selection. Each topic page: paper summary, relation to my history, confidence ratings, and questions to raise with each Czech clinic.

How to use this These pages exist to bring concrete, current evidence into clinic conversations — not to second-guess doctors. Each page distills 1–3 of the strongest papers on one specific decision, scores how confidently each finding applies to me, and ends with questions to ask. The priority tags reflect actionability for my next cycle, not the strength of the underlying science.
Hydrosalpinx — assessment & management High
My Dec 2025 HSG showed bilateral tubal occlusion — but that's not the same as hydrosalpinx. Only the latter is embryo-toxic. A dedicated TVUS is the missing test.
Dual trigger for poor responders High
Strong evidence that hCG + GnRH-agonist co-trigger outperforms hCG-only on MII oocyte yield in DOR / age 40+. My Grace cycle used single trigger.
Thin endometrium management High
My endometrium was 6.1 mm at trigger. Best-supported approach: freeze-all → natural-cycle FET; intrauterine PRP as adjuvant; hysteroscopy before cycle 2.
DHEA supplementation for DOR Medium
Evidence is mixed: ~1 extra egg per retrieval and possibly lower miscarriage, no average live-birth benefit. My low T puts me in the likely-responder subgroup.
Supplements & lifestyle Medium
CoQ10, melatonin, omega-3, Mediterranean diet, exercise — what's supported, what isn't. Honest framing: nothing reliably moves live birth, signals are on surrogate endpoints.
Modified letrozole vs GnRH antagonist Medium
Zhao 2026 RCT in DOR / age 40–45. Protocols matched overall; mLP showed a strong subgroup signal for fresh 2-cleavage transfers but didn't survive correction.
Pushing yield, protecting quality Context
What I can actually change to get more eggs, and whether it costs me on quality. Real movers: 3 cycles not 2, dual trigger, CoQ10 at 600 mg. Skip: testosterone, GH, DHEA, DuoStim. Avoid: OCP priming + antagonist.
Cumulative live birth rates, age 40+ Context
Realistic prognosis for my profile: ~20–30% cumulative LBR after 3 own-oocyte cycles. Curve plateaus at cycle 4. Prior natural birth doesn't predict IVF success at age 40.
