How are Testosteron and Langlebigkeit related?

The relationship between testosterone and longevity is complex and not fully understood. Epidemiological studies suggest that men with lower testosterone levels tend to have longer lifespans, hinting at a trade-off between reproductive investment and longevity. However, very low testosterone is also linked to increased risks of osteoporosis, sarcopenia, and metabolic syndrome, which can impair healthspan. Evidence is mixed: observational data show an inverse association between testosterone and mortality, but no randomized controlled trials confirm a causal role. Testosterone levels are influenced by lifestyle factors (diet, exercise, sleep) that independently affect longevity. Consumer tests like MyBody-X can measure testosterone, but interpretation is limited by diurnal variation and lack of clinical validation for longevity claims. Caution: testosterone supplementation without medical indication may increase cardiovascular risk. In summary, testosterone is a biomarker, not a direct determinant of lifespan; a holistic approach to health is more relevant.
