Conditions that adversely affect erectile health?


Specific steps take place to produce and sustain an erection:
  • Arousal. The first step is sexual arousal, which men obtain from the senses of sight, touch, hearing and smell, and from thoughts.
  • Nervous system response. The brain communicates the sexual excitation to the body's nervous system, which activates increased blood flow to the penis.
  • Blood vessel response. A relaxing action occurs in the blood vessels that supply the penis, allowing more blood to flow into the shafts that produce the erection.

    If something affects any of these factors or the delicate balance among them, erectile dysfunction can result.
