Long-dead eunuchs may help explain long lives

In the industrialized world, women live at least five years longer, on average, than men. Scientists have attributed that difference to everything from healthier habits to hardier cells. Now, a study that analyzes the longevity of eunuchs, or castrated men, suggests that testosterone may play a part in shortening men's lives.

The idea that testosterone, the male sex hormone, affects life span isn't new. Neutered dogs and other animals that have had their sources of testosterone removed often live longer than their intact counterparts. But studies on the connection between castration and longevity in humans are harder to come by, and the results have been inconclusive. A 1969 study of institutionalized patients in Kansas found that castrated men lived an average of 14 years longer than other men in the same facility, but a 1993 study of Italian castrati (singers castrated as boys to preserve their high voices) found nothing unusual about their longevity.

Almost five years ago, biologist Kyung-Jin Min of Inha University in Inchon, South Korea, found himself considering this lack of data while watching a TV drama about eunuchs. Min began to wonder if Korea's rich historical records could shed light on the link between castration and longevity in humans.

Until the late 19th century, Korean rulers employed eunuchs to serve the royal court. These eunuchs were allowed to marry and adopt castrated boys as their sons. The Yang-Se-Gye-Bo, a genealogical record of the eunuch families, has survived, and it documents the birth and death dates and other personal details of 385 eunuchs who lived between the mid-16th century and the mid-19th century.

Min and colleagues from the National Institute of Korean History and Korea University began to pore over the Yang-Se-Gye-Bo. After painstakingly comparing it with other historical records, the team was able to identify and verify life spans for 81 of the listed eunuchs. To rule out the effects of cushy conditions on longevity, they compared the eunuchs' life spans to those of uncastrated men of similar social status living at the same time. The eunuchs outlived their uncastrated contemporaries by 14 to 19 years, the researchers report online in the journal Current Biology.
