A Study on Erectile Dysfunction
Erectile dysfunction, commonly referred
to as ED, is the inability to achieve and sustain an
erection suitable for sexual intercourse. This condition
is not considered normal at any age and is different
from varied problems that interfere with sexual intercourse,
such as lack of sexual desire and problems with ejaculation
and orgasm.
According to the National Institutes of Health, approximately
5 percent of 40-year-old men and between 15 and 25 percent
of 65-year-old men experience ED on a long-term basis.
A much more frequent affliction that affects the majority
of men at some point in their life is the occasional
failure to achieve an erection. This could occur for
a variety of reasons, such as excessive consumption
of alcohol or due to fatigue.
Failure to achieve an erection less than 20% of the
time is not unusual and treatment is rarely needed.
Failure to achieve an erection more than 50% of the
time, however, generally indicates there is a problem
requiring treatment.
In order to achieve an erection three conditions must
occur: The nerves to the penis must be functioning properly;
the blood circulation to the penis must be adequate;
there must be a stimulus from the brain. If there is
something interfering with any or all of these conditions,
a full erection will be prevented.
Common causes of ED include diseases that affect blood
flow; nerve diseases, psychological factors, such as
stress, depression, and performance anxiety; and injury
to the penis and any chronic illness.
Erectile Dysfunction Treatment: Medical specialist
treat ED based on the cause of the problem. Your doctor
may treat you with oral medications based on a study
of your family's medical history as well as your own
and current health.
The Erectile Dysfunction
Drug that is currently in predominant use is Cialis
more than even Levitra and Viagra. All of these works
by increasing the flow of blood into the penis so that
when a man is sexually stimulated, he can get an erection.
Cialis, Levitra, and Viagra work by a similar mechanism
and cause erection. There are slight differences on
how long each of these drugs work and how quickly they
work. Levitra has a longer period of efficacy than Viagra.
They both take effect in about 30 minutes. With Levitra,
the effects last for about 5 hours. With Viagra, the
effects last approximately 4 hours.
Cialis works a bit faster (within about 15 minutes),
and the effects last much longer up to 36 hours in some
cases.
