Castrated men tend to live much longer than fully endowed men, according to a new study published in Current Biology, that could offer clues on how to extend the male lifespan.
Experts say possible negative consequences of castration include “decreased libido,depression and loss of physical strength.
Researchers say eunuchs lived 14 to 19 years longer than other men did. Three even lived to 100 or more, a feat of longevity that remains relatively rare among men even today.
Castration allegedly extends lifespan by reducing male sex hormones -testosterone is known to increase the incidence of coronary heart disease and reduce immune function in males.
Due to this immune function suppression, eunuchs could be better able to resist infections and are less prone to physically dangerous situations that could put them at risk.
The researchers plan to examine the lifespan of eunuchs in other cultures, but few expect young men to willingly undergo castration in order to have lengthier lives.
