Guys, your shakes-the-walls snoring could be a lot more than just annoying noise'it may also be a sign of impending erectile dysfunction. Tests conducted by researchers at the University of Louisville showed that untreated sleep apnea lowers levels of an enzyme that makes nitric oxide in the blood, a key compound that helps with the flow of blood needed for firm erections. The effect was so strong that erectile dysfunction drugs only eased, but did not eliminate the problem. So if you're getting a lot of grumbling about your snoring, you'd better talk with your doctor before you start getting another complaint in the bedroom.
