What is the erectile dysfunction?
Erectile dysfunction (impotence) is the inability to get or maintain an erection
adequate for sexual intercourse. One in ten men (10 percent ) suffer from
impotence and it is observed in almost one third (30 percent ) of diabetic men.
The ability to obtain an erection is important to most men, young and old.
But many men suffer erectile dysfunction in silence, without seeking
help or advice. If There's a problem with one or more of these mechanisms, erection may
fail. During stimulation, nerve impulses travel from the brain to the penis and
activate smooth muscle relaxation in the penis. This promotes blood to
flow into the erectile tissues.
As the penis fills with blood, it expands and becomes erect. During
enlargement, the veins in the penis become compressed, blocking the flow
of blood out of the penis so that erection occurs. The penis stays erect
until ejaculation is finished or sexual arousal ceases.
