How Much Do You Know About Impotence?
The
human erection is an amazing feat of engineering. The progression
from flaccid to firm requires close cooperation between the brain
and the nerves, blood vessels, and muscles that control the penis.
Unfortunately, the delicate process can break down for many reasons,

(the inability to have intercourse because of erectile dysfunction)
is more common among older men, but it can strike at a young age
too. How much do you know about it? Take this short quiz to find
