Erectile dysfunction (ED) is the inability to achieve or maintain an erection sufficient for sexual intercourse. It can be caused by a variety of factors, including physical conditions such as cardiovascular disease, diabetes, high blood pressure, and obesity, as well as psychological factors like stress, anxiety, or depression. Hormonal imbalances, certain medications, smoking, and alcohol use can also contribute to ED. While occasional difficulty with erections is common, persistent erectile dysfunction may indicate an underlying health issue. Treatment options include lifestyle changes such as exercise, weight loss, and reducing alcohol or smoking, as well as medications like phosphodiesterase inhibitors (e.g., Viagra or Cialis), therapy for psychological factors, and, in some cases, medical procedures. Addressing the root cause is important for effective management of ED.
