What role does Hormoncheck Männer play in longevity?

MyBody-X's Hormoncheck Männer measures testosterone, DHEA, cortisol, and other hormones often linked to aging. However, direct evidence that such a test improves longevity is weak. Most studies are observational or mechanistic (e.g., low testosterone associated with higher mortality), but randomized controlled trials on hormone supplementation in healthy men are lacking. Hormone levels fluctuate diurnally and with stress – a single test is a snapshot. MyBody-X markets the test as a 'vitality and energy check', not explicitly as a longevity tool. Interpretation should be conservative: the test may flag imbalances, but without medical follow-up and serial measurements, its impact on lifespan is unproven. Evidence grade: marketing/mechanistic. Caveat: No clinically validated prediction of life expectancy.
