Impotence: Causes and Solutions
Impotence: Causes and Solutions
Impotence affects about one out of every ten American men, yet many
of them don't seek help because they're embarrassed, they think
there's no solution or they believe the problem is "all in their
minds." Unfortunately, these men are missing out on a wide variety of
treatment options.
Impotence, the persistent inability to achieve and maintain an
erection for intercourse, affects as many as 18 million men in the
United States between the ages of 40 and 70. Until recently, doctors
thought impotence was mainly rooted in psychological causes. Now it
is believed that 50 to 70 percent of all cases are caused by physical
problems. Erection difficulties tend to increase with age, but that
is not the only or even the most important factor. Your general
physical and psychological health, as well as lifestyle habits and
certain medications, can all cause impotence, but you don't have to
live with this problem. In most cases, impotence can be successfully
treated.
How Does an Erection Occur?
In order to get an erection, several parts of the body must work
together. The brain sends a message of sexual arousal through the
nervous system to the penis. This message causes the muscles along
the penis to relax. At the same time, the artery to the penis dilates
to twice its diameter, increasing the blood flow sixteen-fold, and
the veins which carry blood away from the penis are blocked. As a
result, the two spongy-tissue chambers in the shaft of the penis fill
with blood and the penis becomes firm. A breakdown in any of these
systems makes getting or keeping an erection difficult.
How is Impotence Diagnosed?
Virtually all men occasionally fail to get an erection. That's
normal. But if a man has trouble getting or maintaining an erection
about 25 percent of the time, he should see an urologist. These
physicians specialize in disorders of the kidneys, bladder, prostate,
penis and urethra.
Usually, after asking questions about when and how the impotence
developed, the urologist will give the patient a complete physical
exam to determine if his hormone levels are normal and if the blood
vessels, nerves and tissues of his penis are working properly. If
this initial work-up doesn't pinpoint the cause of the problem, a
nocturnal penile tumescence test can be done.
Men with no physical abnormalities almost invariably have nightly
erections during sleep. The patient may spend a few nights in a sleep
laboratory where a gauge that measures the frequency and duration of
nocturnal erections is attached to the base of the penis. A home
version of this, the snap-gauge test, can also be used. Before going
to sleep, the patient attaches the gauge to the base of his penis.
During the night, the gauge will break at different degrees of penile
rigidity and show whether a partial or full erection has taken place
during sleep. If nocturnal erections do not occur, the impotence is
most likely physical. Additional testing is then required to identify
the precise cause of the problem.
To Help Prevent Impotence
- Exercise regularly
- Limit the amount of fat and cholesterol in your diet
- Drink only in moderation
- Don't smoke
What Are the Physical Causes of
Impotence?
Physical impotence occurs when there is a problem with any of the
systems needed to get or maintain an erection. The good news is that
potency can usually be restored when a man is treated for underlying
medical conditions, when medications are adjusted or when lifestyle
habits are changed.
Here are some of the top causes of
impotence:
- Vascular Disease. Hardening of the arteries can affect the
artery leading to the penis so that it cannot dilate enough to
deliver all the blood necessary for an erection. Impotence can
also occur if the nerves that control blood flow to the penis are
damaged.
- Diabetes. One out of every four impotent men has diabetes,
which can cause nerve deterioration (diabetic neuropathy).
Impotence may result if nerves or blood vessels that control the
flow of blood to the penis are affected. In some cases, keeping
the diet and blood sugar under control can decrease impotence. But
permanent nerve damage can result in a chronic problem.
- Disease of the Nervous System. Some conditions, such as
multiple sclerosis, Parkinson's disease and spinal cord injuries,
can affect or cause impotence.
- Cancer Surgery. Surgery to remove cancer from the prostate,
bladder, colon or rectal area can cause impotence if the nerves
and blood vessels that control erections are damaged in the
process of removing cancerous tissue.
- Medications. Some prescription medications for high blood
pressure, depression, spinal cord injury, diabetes and other
conditions can cause temporary impotence by interfering with the
nerve impulses or blood flow to the penis. Doctors may be able to
adjust the dosage of a drug or change the medication to reverse or
minimize the problem.
- Smoking. A recent study at the New England Research Institute
in Watertown, Massachusetts, found that impotence was equally
common among smokers and non-smokers in general. However, among
men with certain health problems, those who smoked were much more
likely to have potency problems. For example, 56 percent of
smokers with heart disease were completely impotent compared with
only 21 percent of non-smokers with the disease.
- Alcoholism. Excessive alcohol consumption disrupts hormone
levels and can lead to nerve damage. This type of impotence may be
reversible or permanent depending on the severity of the nerve
damage. Some clinical studies suggest about 25 percent of all
alcoholics become impotent -- even after they stop drinking.
- Hormone Imbalance. Abnormal testosterone levels are rare, but
they can cause impotence. In addition, other illnesses, such as
kidney failure and liver disease, can disrupt the balance of
hormones.
What Are the Psychological Causes of
Impotence?
A man who is depressed, under stress, or worried about his
"performance" during sex may not be able to have an erection.
Qualified therapists or counselors who specialize in the treatment of
sexual problems can often help diagnose and sort through these
problems. Some impotence problems can be solved when a man
understands the normal changes of aging and how to adapt to them. For
example, as men get older they generally need more direct stimulation
to achieve an erection. They may also have less firm erections, take
longer to ejaculate and need more time between erections.

Relationship woes can interfere with potency and so can job
stress, depression or financial worries. Impotence may also be the
result of deep-seated emotional trauma, such as having been sexually
abused as a child. Qualified psychotherapists can diagnose such
problems and help men understand and overcome them.
What are the Treatment Options?
When treatment of underlying physical or psychological problems
fails to restore potency, a man and his sexual partner can consider
one of the following solutions:
- Viagra. The most recent treatment for impotence approved by
the FDA, this prescription drug is expected to benefit 70% of men
with erectile dysfunction and has revolutionized the way impotence
is treated. All a man needs to do is pop a Viagra pill an hour
before sexual activity and the medication works on normal body
chemistry to allow blood to rush into the penis when a man is
sexually stimulated (men should take no more than one pill a day).
Despite all the hype about Viagra, men should exercise caution in
deciding whether this drug is right for them.
- Vacuum Device. With this treatment, a man slips a hollow,
plastic cylinder over his flaccid penis. He then attaches a hand
pump to draw air out of the cylinder, creating a vacuum that draws
blood into the penis. Once the penis is erect, the man slips an
elastic ring over the cylinder onto the base of his penis and
removes the cylinder. The ring will keep blood from flowing out,
allowing intercourse. Note: This device should only be used when
seeing a doctor regularly since mishandling can damage the
penis.
- Self-Injection. One or more drugs (papaverine, phentolamine
and prostaglandin-E1) can be injected into the penis to increase
blood flow. The injection is nearly painless and produces a more
natural erection than a vacuum device or implant. However, until
the proper dose is worked out, a man might have a prolonged and
painful erection. In rare instances, an erection that does not go
down after ejaculation may require surgery.
- Penile Implants. Surgical implants can be used as alternatives
if the above treatments are unsatisfactory. Experts at the Mayo
Clinic say there is a 10 to 15 percent chance that an implant will
malfunction within five years, but the problem almost always can
be corrected. Over 90 percent of patients are satisfied with these
devices. The two major types are:
- Malleable Rods. Two long rods (also referred to as semi-rigid
prostheses) are inserted into the outer channels of the penis
through a small incision in the lower abdomen or scrotum. Each rod
is one solid piece and so remains erect at all times. However,
they can be bent close to the body for concealment. Because there
are no moveable or inflatable parts, malfunctions are rare.
- Inflatable Cylinders. These devices consist of one or two
inflatable cylinders, a finger-activated pump and an internal
reservoir that stores liquid used to inflate the tubes. All
components -- the cylinders, pump and reservoir -- are implanted
within the penis, scrotum and lower abdomen respectively. When the
pump in the scrotum is manually squeezed several times, the fluid
from the reservoir is released into the cylinders. They expand and
create an erection, which is maintained until the release valve on
the pump is squeezed to return the fluid to the reservoir.
