Scientists say they’ve finally found a gene implicated in erectile dysfunction, a discovery that could help illuminate how the condition occurs on the most basic level.
The condition is widespread among older men — some estimates put it at 40 percent or higher for men over 40 — and it’s thought to be influenced by a range of factors. Poor body weight, cardiovascular health, a lack of exercise and many other things can all predispose men to erectile dysfunction (ED). But our genes matter, too.
Studies of twins had previously shown that around a third of the condition could be chalked up to genetics, though what genes were at play was unknown. Now, researchers have pinned down several variants in a single genetic region that they say likely plays a role in sapping sexual vigor. Looking at genetic profiles from 36,000 men enrolled in a study funded by healthcare company ...
