Can Testosteron help with longevity?

Whether testosterone can extend lifespan is not scientifically settled. Observational studies show that low testosterone in men is associated with higher all-cause mortality, but this may reflect underlying illness rather than causation. Randomized controlled trials of testosterone supplementation in healthy older men have not demonstrated a clear longevity benefit, and some suggest increased risks for cardiovascular events, sleep apnea, and prostate issues. For women, evidence is even scarcer, and testosterone is not routinely used for longevity. The evidence is largely mechanistic (effects on muscle mass, bone density) or based on animal models and epidemiological correlations. No robust human trial shows that raising testosterone in eugonadal individuals prolongs life. Consumer hormone tests (like those from MyBody-X) can indicate levels but cannot diagnose deficiency or predict longevity outcomes. Supplementation should only be considered under medical supervision for clinically low levels. In summary, testosterone may improve quality of life in deficiency, but as a longevity intervention it lacks solid evidence.
