Scientists have determined that men can extend their lives but I expect there will be few takers. By studying the genealogy records of Imperial Court of the Korean Chosum Dynasty, the researchers at Korean University found that eunuchs had significantly longer lives than their contemporaries. The difference would suggest that it is male sex hormones that shorten the life expectancy for males.
Many of these boys were castrated by a common accident at the time — they were castrated by dogs. Some were castrated to gain entrance in the palace. Both groups lived substantially longer.
Of the 81 eunuchs studied, three lived to age 100 or more and the incidence of centenarians was 130 times greater than developed countries.
By the way, the shortest life expectancy was found among the Korean Royal males.
