Erectile Dysfunction

What Causes Erectile Dysfunction (ED)?

ED can have physical, psychological, or mixed causes. Common contributors include:

• Reduced blood flow
• Stress, anxiety, or performance pressure
• Hormonal changes
• High blood pressure, diabetes, or high cholesterol
• Certain medications
• Relationship or emotional stress

Understanding the cause is the first step toward effective treatment.

How ED Medication Works

Sildenafil, tadalafil and vardenafil all belong to a group of medicines called PDE5 inhibitors. They work by improving blood flow to the penis during sexual stimulation. They do not cause an automatic erection — arousal is still required.
