Erectile dysfunction FAQ


What causes erectile dysfunction?

Achieving and maintaining an erection is a complex physiological process that involves hormones, nerves, muscles and blood vessels, as well as the emotions. When a problem arises in any of these areas, erectile dysfunction (ED) can occur. Plus, lifestyle factors can also play a role in ED, and in many men, it's a combination of two or more factors that combine to cause symptoms.

Some of the most common causes of ED include:

  • Vascular disease such as atherosclerosis (“hardening” of the arteries)
  • Heart disease
  • High cholesterol or high blood pressure
  • Obesity
  • Parkinson's disease
  • Multiple sclerosis
  • Scar tissue inside the penis (Peyronie's disease)
  • Injury or surgery affecting the pelvic region or spinal cord
  • Alcoholism and drug abuse
  • Certain prescription medications
  • Smoking
  • Treatments for prostate issues including cancer and prostate enlargement
  • Stress, anxiety or depression

Understanding the possible causes is the first step in making sure you get the most appropriate and most effective treatment.


How can erectile dysfunction be treated?

There are several types of treatment for ED, depending on the underlying causes, including:

  • Oral medications to help increase blood flow to the penis, essential for achieving and maintaining an erection
  • Injectable medications to increase blood flow
  • Penis pumps
  • Penile implants
  • Psychological counseling for stress, emotional issues or relationship problems
  • Losing weight
  • Begin more physically active
  • Quitting smoking
  • Lifestyle changes can also help in some cases.


What is a penile implant?

Penile implants are devices that are surgically placed inside the penis to help achieve and maintain an erection. The devices may comprise semi-rigid rods or inflatable chambers that can be enlarged with a pump that's implanted in the scrotal sac. Penile implants are usually considered only when other methods and treatments for ED have been tried and have been determined to be unsuccessful.

Implantation involves a simple, same-day procedure.
