What role does Fertility Check play in longevity?

The question about the role of a Fertility Check in longevity is interesting, but the provided context does not contain specific information about such a test. In general, fertility markers (e.g., AMH, FSH) reflect reproductive aging, which is correlated with biological aging and overall healthspan. However, direct evidence linking a consumer fertility test to longevity outcomes is lacking. Most consumer tests are marketed with broad health claims, but their predictive value for lifespan or healthspan is not validated by robust human studies. The evidence grade for this specific question is therefore 'unclear' due to absence of relevant context. A cautious interpretation is warranted: while reproductive health is a component of overall health, a standalone fertility check cannot be considered a longevity test. No specific sources (PMIDs, DOIs, guidelines) were provided in the context to support a stronger claim.
