What causes erectile dysfunction?

Erectile dysfunction (ED) occurs when a man has trouble getting or maintaining an erection firm enough for sexual activity. This typically results from insufficient blood flow to the penis. However, there are many possible factors that can cause ED, including: physical factors such as cardiovascular conditions; diabetes and high blood pressure; psychological factors such as stress, anxiety or depression; lifestyle choices such as smoking, excessive alcohol consumption and drug use; hormonal imbalances; neurological conditions; age; and medications. It is important that you share all of these details with your medical provider before requesting treatment.
