Impotence is the inability to achieve or sustain
an erection, and most men will experience this very frustrating
problem at some time. It can either be a once-in-a-lifetime problem,
or occur periodically or chronically.

of other problems, since it could lead to the man questioning his
sexual prowess. Several diseases such as diabetes can cause
impotence; yet, other factors such as worry, over-work, and fatigue
can cause this highly frustrating experience.

Zinc is an ingredient needed for testosterone manufacture and for
sperm production. A shortage of zinc can also contribute to mental

point to keep in mind is to discuss any sexual problem with your
partner - this will clear the air, and will also help to lessen any
psychological pressure that you may be feeling.
