Hormonal Balance and Longevity

Sex differences in longevity may be influenced by hormonal factors, particularly the effects of testosterone and estrogen. Research and historical examples, such as the significantly longer lifespan of castrated Korean eunuchs compared to their non-castrated counterparts, suggest that reduced testosterone levels can lead to increased longevity. This indicates a potential link between male hormones and shorter life expectancy, emphasizing the need to further investigate the impact of sex hormones on biological longevity.
