IVF Genetic Tests: Selling a Dream of 'Perfect' Babies, But Risks Outweigh Benefits

• IVF genetic tests market claims to predict 'tallest, smartest, healthiest' children, but benefits are minimal and risks are real.
• These tests generate 'polygenic risk scores' for complex traits like IQ, height, and late-onset diseases, unlike single-gene tests.
• Research shows predictions are highly uncertain; mathematical modeling indicates only marginal benefits (e.g., a few IQ points, 1-3 cm in height).
• Genetic patterns from past populations may not predict future outcomes due to vastly changed environments and gene-environment interactions.
• Ethical concerns include echoes of eugenics, potential for discrimination, decision paralysis for parents, and trading proven IVF risks for unproven benefits.
