An erection is produced via a complex chain of events. These include signals from the man’s nervous system due to some sexual stimuli; the site of his partners naked body for example. His body will release chemical messengers within the tissues of his penis. These cause the blood vessels within his penis to widen. It does this by relaxing a thin layer of muscle that is found in the blood vessel walls. The result is that more blood is allowed to enter the penis and it becomes engorged; making it larger, harder and erect. Viagra is a phosphodiesterase inhibitor. It works by helping to increase blood flow into the penis during sexual stimulation. This helps you to achieve and maintain an erection.

Viagra contains the active ingredient sildenafil; this is a drug that has proven useful in the treatment of erectile dysfunction also known as impotence. Impotence is when a man cannot acquire or maintain an erection. This can make penetrative sex virtually impossible. Impotence can have a severely damaging effect upon a man’s confidence and self esteem; no matter how much his partner tries to reassure him. Sadly, this loss of confidence can serve to make the problem of having an erection even more pronounced.
If you have any concerns, you should talk first to your doctor before using Viagra.
