Erectile Dysfunction

Dr. Jones treats patients with erectile dysfunction

Erectile dysfunction (ED) is the inability to obtain or maintain an erection. Although many men have difficulty with erections at times, a consistent inability to get and keep an erection may be a sign of an underlying problem.

Erections are a spontaneous response to physical or emotional stimulation. When a man becomes aroused, his brain sends signals to the nerves in his penis, causing the muscles to relax. When the muscles relax, blood flows into the penis, causing it to become erect.

Certain diseases, medical conditions, or lifestyle issues can interfere with blood flow to the penis or signals from the brain to the spinal cord, leading to erectile dysfunction. Psychological issues, such stress, depression, or performance anxiety, can also cause ED
