Is Fertility Check | Fruchtbarkeits-Test useful for Langlebigkeit?

A fertility check (e.g., hormone panel, AMH, sperm analysis) is primarily designed for reproductive medicine, not for longevity assessment. While some biomarkers like Anti-Müllerian Hormone (AMH) or testosterone may indirectly correlate with biological aging, the evidence for a direct prediction of lifespan or healthspan is weak. Most fertility tests are validated in young, fertile populations, not in older or long-lived cohorts. Additionally, genetic variants affecting fertility are often pleiotropic and may have both beneficial and detrimental effects on longevity. A standalone fertility test without additional longevity markers (e.g., telomere length, epigenetic clocks) is insufficient for longevity evaluation and should not be marketed as such. The evidence level is 'unclear'.
