Genetic Link To Some Cases Of Impotence

Scientists say they've located the first well-documented genetic glitch that increases a man's risk of impotence. 

Most impotence isn't caused by genetics, but rather things like obesity, diabetes, heart disease, smoking, drug and alcohol use, stress or anxiety. 

Still, scientists report they've found a spot in human DNA where genetic variation might boost a man's risk by about 25 percent.

The finding may someday lead to new treatments.
