How are Fertility Check and longevity related?

The relationship between a Fertility Check and longevity is not directly addressed in the provided context. Fertility tests (e.g., AMH, FSH) assess ovarian reserve and hormonal status, which are linked to reproductive aging. Reproductive aging is part of overall aging, but a direct causal link to lifespan is not established. Evidence comes mainly from association studies (e.g., later menopause associated with slightly longer life expectancy), but mechanisms remain unclear. MyBody-X Fertility Check is a commercial test, not a medical diagnostic. Its connection to longevity is speculative and not based on validated longevity biomarkers. Caution is warranted against marketing hype: a fertility test may indicate reproductive potential but does not measure healthspan or lifespan. For longevity assessment, other biomarkers (e.g., telomere length, epigenetic clocks) are more evidence-based. Evidence grade: marketing/unclear.
