Erectile Dysfunction cover a
range of disorders, including:-
- Curvature of the penis during erection,
- Prolonged painful erection not associated
with sexual desire and
- Premature Ejaculation (PE). But usually
it refers to the inability to obtain an adequate erection
for satisfactory sexual activity.
Signs and Symptoms
- Inability to obtain a full erection
- Inability to maintain an erection throughout
intercourse
- Complete inability to achieve an erection
Erectile Dysfunction
Causes
The penis contains two cylindrical,
sponge-like structures that run along its length, parallel
to the tube that carries semen and urine (urethra). When a
man becomes sexually aroused, nerve impulses cause the blood
flow to the cylinders to increase about seven times the normal
amount. This sudden influx of blood expands the sponge-like
structures and produces an erection by straightening and stiffening
the penis. Continued sexual arousal or excitation maintains
the higher rate of blood flow, keeping the erection firm.
After ejaculation, or when the sexual excitation passes, the
excess blood drains out of the spongy tissue, and the penis
returns to its no erect size and shape.
Specific steps take place to
produce and sustain an erection:
- Arousal: The first step
is sexual arousal, which men obtain from the senses of
sight, touch, hearing and smell, and from thoughts.
- Nervous system response:
The brain communicates the sexual excitation to the body's
nervous system, which activates increased blood flow to
the penis.
- Blood vessel response:
A relaxing action occurs in the blood vessels that supply
the penis, allowing more blood to flow into the shafts
that produce the erection.
If something affects any of
these factors or the delicate balance among them, erectile
dysfunction can result.
Nonphysical causes may account
for impotence. They may include:
- Psychological problems:
The most common nonphysical causes are stress, anxiety
and fatigue. Impotence is also an occasional side effect
of psychological problems such as depression.
- Negative feelings: Feelings
that you express toward your sexual partner - or that
are expressed by your sexual partner - such as resentment,
hostility or lack of interest also can be a factor in
erectile dysfunction.
Still, the most frequent cause
of erectile dysfunction isn't always psychological. Physical
causes account for many cases of erectile dysfunction. These
physical causes include:
- Nerve damage from longstanding diabetes
(diabetic neuropathy)
- Cardiovascular disorders affecting the
blood supply to the pelvis
- Certain prescription medications
- Operations for cancer of the prostate
- Fractures that injure the spinal cord
- Multiple sclerosis
- Hormonal disorders
- Alcoholism and other forms of drug abuse
In fact, erectile dysfunction
may be one of the first signs of an underlying medical problem.
The physical and nonphysical
causes of erectile dysfunction commonly interact. For instance,
a minor physical problem that slows sexual response may cause
anxiety about attaining an erection. Then the anxiety can
worsen your erectile dysfunction.
Prevention
Although most men experience
episodes of erectile dysfunction from time to time, you can
take these steps to decrease the likelihood of occurrences:
- Limit or avoid the use of alcohol and
other similar drugs,
- Stop smoking,
- Exercise regularly,
- Reduce stress,
- Get enough sleep,
- Deal with anxiety or depression,
- See your doctor for regular checkups and
medical screening tests.
Erectile Dysfunction
Treatment
ED drugs like Generic Cialis,
Generic Viagra
and Generic Levitra belongs to a group of drugs containing
PDE-5 inhibitors, these drugs work by relaxing the blood vessels
and allowing blood to flow into the penis. The result is a
natural erection.
