Myths vs facts: Fertility Check and Langlebigkeit

Myths vs facts about Fertility Check and Longevity tests: Many consumer DNA tests claim to predict fertility or lifespan based on genetic variants. However, the effects of individual genes on these complex traits are very small. A test screening for 'fertility genes' or 'longevity genes' cannot replace a medical diagnosis. The evidence is typically weak (associative, GWAS) or based on marketing. Lifestyle, environment, and chance play a far larger role. Such tests may serve as motivation for healthier habits, but they are not reliable predictions. For actual fertility issues or anti-aging concerns, consulting a specialist (reproductive endocrinologist, geriatrician) is essential.
