Erectile Dysfunction is the inability to achieve or maintain an erection sufficient for sexual intercourse. While it can affect men at any age, it becomes more prevalent as men age, especially after 50. ED can be caused by a range of factors, including physical conditions like diabetes, heart disease, and high blood pressure. Lifestyle factors such as smoking, alcohol use, and lack of physical activity also contribute to ED, as well as psychological issues like stress, anxiety, and depression.
