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

When combining a Fertility Check with longevity insights, caution is warranted. Fertility tests typically examine SNPs in genes like FSHR, ESR1, or MTHFR, which have modest effects on reproductive health. Longevity tests focus on variants in FOXO3, SOD2, APOE, etc., with small effect sizes (OR <1.2) from GWAS. There is little direct evidence linking fertility-related genetic markers to lifespan. For example, MTHFR variants affect folate metabolism but are not robustly associated with longevity. The risk is overinterpretation: a 'risk allele' for reduced fertility does not imply shorter life. Lifestyle factors (diet, exercise, smoking) dominate longevity outcomes. Evidence for a combined predictive value is weak (mixed). Consumer DNA tests are not diagnostic; they indicate tendencies. Users should not make drastic health decisions based solely on these results. Consulting a physician or genetic counselor is recommended before taking supplements or changing habits. The scientific consensus remains that polygenic scores for fertility and longevity have limited clinical utility.
