What to watch with Fertility Check | Fruchtbarkeits-Test and Langlebigkeit?

Combining fertility and longevity tests (e.g., MyBody-X) sounds appealing, but the evidence is weak. Fertility tests often examine single gene variants (e.g., MTHFR, FSH receptor) that explain only a small fraction of fertility. Longevity tests rely on markers like FOXO3 or APOE, whose effects are modest and population-specific. A direct link between these two domains is not scientifically established. Be cautious: such tests do not replace clinical diagnosis. The risk is overinterpretation – a 'bad' result for one gene does not mean infertility or shortened lifespan. Always consult a doctor or genetic counselor before taking action. Most consumer tests lack medical approval. Evidence: unclear, based on mechanistic and marketing claims.
