Scientists from New Zealand have found that the removal of reproductive organs in rams helps to prolong life. Experts do not exclude that castration can be a radical, but effective way to prolong the life of men. A related study was published in the journal eLife.
It is noted that in mammals, females generally have a longer lifespan than males. At the same time, farmers and scientists alike know that removing testicles from rams can extend their life by 60 percent. However, the mechanisms underlying longevity were unclear.
To understand what is happening at the DNA level, New Zealand scientists have teamed up with American geneticist Steve Horvath, who invented the epigenetic clock – a way to measure biological age using DNA analysis. From these, the researchers measured biological aging based on chemical labels. It turned out that in castrated rams, the aging rate is slowed down compared to non-castrated males.
According to other studies, castration prolongs the lifespan of laboratory rodents, domestic cats and dogs. In addition, in the XIV-XX centuries, eunuchs at the court of Korean kings lived longer than their contemporaries. Similar results were shown by a study conducted among patients in a psychiatric hospital in the United States.
The fattest castrated male lynx died in Germany last year. A male named Rufus became famous on social networks in 2018 due to his excess weight. The weight of the lynx has reached 43 kilograms, while on average its congeners weigh from 16 to 30 kilograms.
