Excessive Testosterone Raises Mortality Risk in Older Men

Excessive Testosterone Raises Mortality Risk in Older Men

Older men whose testosterone levels were neither low nor high tended to live longer, according to new research accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology Metabolism.

Testosterone is a key male sex hormone involved in maintaining sex drive, sperm production and bone health. Physicians have long known that low testosterone levels can signal health problems, but the new study found men may not fare better when levels of the hormone rise too high.

A Genetic Variation That Could Protect Skin From Sun Damage Fuels Testicular Cancer

A Genetic Variation That Could Protect Skin From Sun Damage Fuels Testicular Cancer

A Ludwig Cancer Research study published in Cell today identifies a common mutation that dramatically increases the risk for testicular cancer—and describes a likely molecular mechanism by which it exerts that effect. The researchers also suggest why, despite its potential lethality, the genetic variation has been favored by natural selection to become common in light-skinned people. It appears this mutation might aid the tanning of Caucasian skin in response to sunlight, protecting it from UV radiation, which can burn and cause cancer.
