What role does Fertility Check play in Langlebigkeit?

A Fertility Check (e.g., AMH, FSH, inhibin B) provides insights into ovarian reserve and reproductive aging. Since reproductive lifespan is linked to overall biological aging—later menopause is associated with increased longevity—such a test can indirectly inform about longevity. However, the relationship is mechanistic, not causal: a low AMH does not predict shortened lifespan but merely reflects age-related decline in egg reserve. Evidence comes mainly from epidemiological studies showing associations between fertility markers and mortality, but without individual predictive power. Lifestyle factors (diet, exercise, stress) dominate longevity far more. Thus, a Fertility Check is not a direct longevity test but can serve as a complementary piece in a broader biological age assessment. Interpretation requires clinical context and family history.
