Researchers have pinpointed a specific place in the human genome that raises the risk of erectile dysfunction. The breakthrough marks a significant advancement in the understanding of genetics—and another win for men. The inability to get it up is a common condition among middle- and older-aged penis owners; the “disease” is linked to various causes, including neurological, hormonal, and vascular factors. Genetics are also suspected in about one-third of impotence cases, according to managed care consortium Kaiser Permanente, which pointed out that there is no known association with any specific genome locations.
