Is Testosteron useful for Langlebigkeit?

The question of whether testosterone promotes longevity is not scientifically settled. Observational studies suggest that normal testosterone levels in men are associated with lower all-cause mortality, possibly due to benefits on muscle mass, bone density, and cognition. However, long-term randomized controlled trials proving a causal effect on lifespan are lacking. Testosterone therapy also carries risks such as cardiovascular events, sleep apnea, and prostate issues. The evidence is therefore moderate at best. Crucially, testosterone should only be used for confirmed deficiency under medical supervision. Relying on testosterone alone for longevity is not evidence-based; lifestyle factors like diet, exercise, and stress management have stronger support.
