Why do castrated men (eunuchs) live longer?

 title: 'Castrated Males Live Longer'

Castrated men, known as eunuchs, tend to live longer than their uncastrated counterparts due to several factors. A Korean study found that eunuchs lived an average of 70 years, around 15 years longer than intact men from similar social statuses[3][6]. The absence of testosterone, a hormone linked to various health issues, is believed to contribute to this increased longevity[6]. Lower testosterone levels may help reduce risks of cardiovascular diseases and certain cancers, leading to a healthier and longer life[4][6].

Castration also prevents the physiological changes associated with puberty, which can impact health in ways that contribute to shorter lifespans in men[6]. Eunuchs often experienced different lifestyles, and their roles in society were primarily non-aggressive and focused on service, which may also have influenced their longevity[6].
