Overview
When men
become sexually aroused, hormones, muscles, nerves, and blood vessels
all work with one another to create an erection. Nerve signals, sent
from the brain to the penis, stimulate muscles to relax. This, in turn,
allows blood to flow to the tissue in the penis. Once the blood fills
the penis and an erection is achieved, the blood vessels to the penis
close off so that the erection is maintained. Following sexual arousal,
the veins to the penis again open up, allowing the blood to leave.
At
some point in a man’s life, he may have difficulty achieving or
maintaining an erection. Erection problems occur when you can’t achieve
or maintain an erection that’s firm enough to have sexual intercourse.
For most men, this problem occurs occasionally and isn’t a serious
issue. However, if you are unable to achieve an erection one-quarter of
the time or more, you may have a health problem that requires medical
attention.
Erection problems can also be due to issues of the
mind. Emotional issues can distract a man of any age from becoming
aroused, and include:
- worry over not being able to achieve or maintain an erection
- prolonged emotional distress related to economic, professional, or social issues
- relationship conflicts
- depression
