What are the main causes of erectile dysfunction?

ED can result from a combination of physical and psychological factors. Physically, it’s often related to poor blood flow to the penis due to conditions like heart disease, high cholesterol, diabetes, or high blood pressure. Hormonal imbalances (like low testosterone), nerve damage from surgeries or injuries, and side effects from medications can also play a role. Psychologically, stress, anxiety, depression, and relationship issues can all interfere with sexual performance. In many cases, both physical and psychological causes are present. Identifying the root cause is key to finding the right treatment. Healthy lifestyle habits, addressing mental health, and consulting a doctor can significantly improve ED.
