Harry Fisch, MD, Urology, answeredDrinking alcohol adversely affects a man's erection, because it's a depressant. In this video, urologist Harry Fisch, MD, explains how both short-term and long-term alcohol use negatively impacts a man's ability to maintain an erection.
Good In Bed answeredA couple of drinks can loosen inhibitions, allowing people to explore their sexuality in a relaxed manner. However, alcohol can also impair sexual functioning. Alcohol is a depressant. It works on the nervous system by slowing down brain function, breathing and pulse. The effect is often psychologically stimulating, since emotions and desires flow more freely. However, while alcohol may boost sexual desire by helping a person to relax, it can decrease performance, especially where erections are concerned.
During a typical erection, blood flows to the penis where more of it stays in than is released. Alcohol works to dilate blood vessels in the body, including in the penis. As a result, blood vessels in the penis stay open, blood flows out and the penis does not become rigid or achieves some degree of hardness but has difficulty staying firm. Limit alcohol intake to 1-2 drinks (or none at all) for optimal sexual function. Alcohol consumption that regularly interferes with sexual function may be a sign of a problem; counseling or therapy may be useful.
