Erectile dysfunction (ED) is often associated with other diseases, such as diabetes, neurological diseases, vascular disease, and prostate cancer. It can also be associated with medical conditions, such as high blood pressure, high cholesterol, low testosterone, and prostate enlargement.
In order to get and keep an erection, your blood vessels, nerves, brain, and spinal cord all need to be in good working condition. When it is time to get an erection, the brain sends signals to the nerves (via the spinal cord). The nerves trigger the muscles to relax and the blood to flow through the blood vessels into the penis. If the blood vessels or nerves are damaged due to illnesses such as heart disease, hardening of the arteries, or diabetes, the blood flow to the penis can become impaired. If the brain or spinal cord is damaged due to neurological disorders such as multiple sclerosis or Parkinson’s disease, the ability to transmit signals from the brain to the nerves becomes impaired.
