Fertility tests typically assess reproductive health markers (e.g., AMH, FSH, or specific genetic variants) that are not established as predictors of longevity. Longevity is a multifactorial trait influenced by genetics, lifestyle, environment, and chance; individual fertility markers have negligible or no proven impact on overall life expectancy. Furthermore, MyBody-X tests are consumer lifestyle products, not medical diagnostics. The evidence for any longevity benefit from a fertility check is therefore 'unclear' or 'marketing'.
