Erectile Dysfunction, which is also called ED, and impotency, means that a man is unable to achieve and sustain an erection that’s adequate for sexual intercourse more than half of the time. It is a different condition from having problems related to ejaculation, orgasm or having sexual desire.
A full erection requires that all three of the following things take place at the same time:
- Proper functioning of the nerves of the penis
- Adequate blood supply to the penis
- A stimulus from the brain
Common conditions that cause erectile dysfunction include: atherosclerosis (narrowing of the arteries), nerve disorders, stress, depression, performance anxiety, injury of the penis, and certain medications. Some of the psychological conditions mentioned above may be associated with excess alcohol drinking (more than three drinks a day), which is another reason for limiting alcohol intake.
