What is erectile dysfunction?

Erectile dysfunction (ED) is a medical condition where a man has difficulty achieving or maintaining an erection sufficient for sexual intercourse. It can be caused by physical factors such as heart disease, diabetes, or hormonal imbalances, as well as psychological factors like stress, anxiety, or depression. ED is common, especially as men age, but it is treatable. Treatment options may include lifestyle changes, medications, therapy, or medical procedures, depending on the underlying cause.
