Embryo Selection’s Transferability Paradox

Commercial embryo‑selection services tout high predictive accuracy, but their effectiveness depends on ancestry‑matched genetic data; that mismatch (the transferability paradox) means benefits will be uneven across populations and that claimed gains may not generalize. Regulators, clinicians, and prospective parents must therefore evaluate claims against ancestry coverage, not just headline accuracy numbers. — This matters because it reframes debates about reproductive genetics from abstract improvement claims to a concrete distributional and regulatory problem: who gets reliable predictive benefits and who does not.
