What role does Longevity DNA Test play in Fruchtbarkeit?

A Longevity DNA Test analyzes SNPs in genes like APOE, FOXO3, SIRT1, and KLOTHO, which have been associated with extreme longevity in population studies. However, effect sizes are very small (odds ratios 1.2–1.5) and explain only a tiny fraction of lifespan variance. For fertility, there is no direct, validated predictive value. Fertility is primarily governed by hormones (estradiol, progesterone), menstrual cycle phases, lifestyle, environment, and reproductive genetics—not by 'aging genes.' Some tested genes might theoretically influence egg aging or oxidative stress, but no clinical studies demonstrate a predictive benefit. Marketing such tests as 'fertility aids' is therefore misleading. A Longevity DNA Test cannot assess current fertility, ovulation, or ovarian reserve. For serious fertility concerns, hormone analysis, medical evaluation, and possibly reproductive genetic testing (e.g., FMR1, CFTR) are appropriate. Evidence: marketing/unclear.
