Overview

Erectile dysfunction (ED) means you are unable to get an erection or keep it long enough for sex. It's a very common issue, particularly for men over 40, and often isn't a sign of a serious problem. Sometimes, ED is temporary and caused by factors like stress, being tired, or drinking too much alcohol. It can also be a side effect of certain medications you might be taking. If ED happens often, it could point to an underlying health condition such as high blood pressure, diabetes, or depression. Fortunately, there are many effective treatments and lifestyle changes that can help manage and improve the condition.
