What Causes ED?

LeRoy Jones, M.D., give patient innovative treatment options for male incontinence

Erections occur in response to physical or emotional stimulation. When a man becomes aroused, the brain sends signals to the nerves causing the muscles of the penis to relax. When the muscles relax, blood flows into the penis, which causes it to expand.

It’s not unusual for men to sometimes have problems getting or keeping an erection, but if the problem persists, there may be an underlying cause.
