New proof testosterone reason women outlive men: study

WASHINGTON - Scientists said Monday they have new evidence about why women live longer than men, from a study of historical data showing castrated Koreans far outlived their non-eunuch contemporaries.

The study, published in the scientific journal "Current Biology," used detailed genealogical records of the Imperial nobility during Korea's Joseon dynasty, which spanned more than 500 years from the late 1300s to the early 1900s. According to the data, most men, including kings and royal family members, died in their late-40s or early-50s.
But noble-class eunuchs -- men who were castrated either by accident or because of social benefits -- lived, on average, to the ripe, old age of 70.

Study author Kyung-Jin Min of South Korea's Inha University, told AFP the reason is probably that manly hormone, testosterone:
"Testosterone is known to increase the incidence of coronary heart disease and reduce immune function in males," he said.

Castration "removes the source of male sex hormones," the study notes, adding the practice has already been proven to help many male animals live longer. Castration also cuts off the possibility of reproduction, which Kyung-Jin noted could also be a factor.

According to "one of the leading theories of aging, aging occurs at the expense of reproduction," he said, because the body has limited energy that can be used either to keep up reproductive function, or else to keep up everything else.

But although the eunuchs could not father children biologically, they married, adopted and raised children, and generally lived lives very similar to their non-castrated peers. "In order to eliminate socioeconomic factors that could have affected lifespan, the lifespan of the eunuchs was compared to the lifespan of men from other Yan-ban (noble class) families with a similar socioeconomic status," Kyung-Jin said. And "to exclude genetic factors that could have affected the lifespan, we compared the lifespan of eunuchs with multiple Yan-ban families."

Modern men looking to extend their lifespan could consider "testosterone reduction therapy," but Kyung-Jin said it's probably premature.

For one thing, it is not clear if it would have an effect if the therapy were started at an older age -- the eunuchs were all castrated as children.
And for another, the therapy could have side effects that some men may feel make that longer life less worth living.
"We may need to consider the side effects of it," Kyung-Jin said, "mainly, reduction of sex drive in males."

Is castration the secret to a long life?

Scientists believe they may have discovered the secret to longevity for men - but it comes at a painfully high price.

Researchers have shown that eunuchs living in Korea centuries ago outlived other men by a significant margin.

They say their findings suggest that male sex hormones are responsible for shortening the lives of men.

The evidence comes after study of genealogy records of noble members of the Imperial court of the Korean Chosun dynasty (AD 1392-1910).

Kyung-Jin Min, of Inha University, said: "This discovery adds an important clue for understanding why there is a difference in the expected life span between men and women."

The castrated boys in Korea lost their reproductive organs in accidents, usually after being bitten by dogs, or underwent castration purposefully to gain early access to the palace.

Eunuchs were allowed to marry and had families by adopting castrated boys or normal girls.
People in those days kept careful genealogy records as proof that they were of the noble class.
By poring over those records, Min and his colleague Cheol-Koo Lee, of Korea University, found that eunuchs lived 14 to 19 years longer than other men did.
Amongst the 81 eunuchs they studied, three lived to the age of 100 or more, a feat of longevity that remains relatively rare even in developed countries today.
They noted the incidence of centenarians among Korean eunuchs is at least 130 times greater than it is in the developed countries.
They argued the long life span cannot be explained simply by the benefits of life in the palace, as eunuchs spent as much time outside the palace as they did within it. Kings and male members of the royal family tend to have abnormally short lives, typically surviving only to their mid-forties.
The research team, whose findings were published in the journal Current Biology, said their findings may offer some clues to life extension.

Get your bollox chopped off and live a few years longer, think i'll pass.

Do Katoey's have longer or shorter life spans ? I wonder. I can't say I've seen an aged one.

Modern feminine man has gone totally moronic.

Add it to the list of what to do to live longer, and you may as well commit suicide now.
