Myths vs facts: Fertility Check | Fruchtbarkeits-Test and Langlebigkeit

Combining fertility checks with longevity is often surrounded by myths. Fact: A fertility test (e.g., AMH, FSH, semen analysis) provides a snapshot of reproductive health, but does not directly predict lifespan. Longevity is influenced by many factors – genetics, lifestyle, inflammation, oxidative stress. Some biomarkers overlap (e.g., oxidative stress impairs both fertility and aging), but a fertility test alone is not a longevity test. Myth: 'Good fertility equals long life' – unsupported. Similarly, antioxidant supplements (e.g., vitamin E, β-carotene) are marketed for fertility and anti-aging, yet RCTs (SELECT) show increased risks (prostate cancer). Evidence for benefit is weak, for harm at high doses it exists. DNA-based fertility tests (e.g., MTHFR, FMR1) have small effects and are not predictive of longevity. Recommendation: Fertility checks are useful for family planning, but not as a proxy for general health or lifespan. Blood levels (vitamin D, selenium) should be measured, not blindly supplemented.
