Testosterone supplements may be used
for cases where there is a hormonal
deficiency. However, usually the cause
is lack of adequate penile blood supply
as a result of age-dependent damage of
inner walls of blood vessels.
Previously, medical substances (e.g.
apomorphine) were directly injected
into the erectile tissue of penile
shaft to treat impotence. In some cases
a penile implant (penile prosthesis)
could be advised.
Treatments (with the exception of
testosterone supplementation, where
effective) work on a temporary basis:
they enable an erection to be achieved
and maintained long enough for
intercourse, but do not permanently
improve the underlying condition.
Erectile Dysfunction can in many cases
be treated by drugs taken orally,
injected, or as penile
suppositories.
When these methods fail, a
purpose-designed external vacuum pump
can be used to attain erection, with a
separate compression ring fitted to the
penis to maintain it. These pumps
should be distinguished from other
"penis pumps" (supplied without
compression rings) which are claimed to
increase penis length if used
frequently, or vibrate as an aid to
masturbation.
More drastically, inflatable or rigid
penile implants may be fitted
surgically. All these mechanical
methods are based on simple principles
of hydraulics and mechanics and are
quite reliable, but have their
disadvantages.
In a few cases there is a vascular
problem which can be treated
surgically.
PDE5 Inhibitors
The prescription PDE5 inhibitors
sildenafil (Viagra), vardenafil
(Levitra) and tadalafil (Cialis) are
prescription drugs which are taken
orally.
Bremelanotide
The experimental drug Bremelanotide
(formerly PT-141) does not act on the
vascular system like the former drugs
but increases sexual desire and drive
in male as well as female. It is
applied as a nasal spray. Bremelanotide
works by activating a part of the
brain. It is awaiting FDA
approval.
Ginseng
A double-blind study appears to show
evidence that ginseng is better than
placebo.
Enzyte
Enzyte is a product that has been
advertised by saturation coverage on
television channels such as Court-TV.
However, the Center for Science in the
Public Interest (CSPI) has filed a
complaint with the Federal Trade
Commission (FTC) about Enzyte for
deceptive advertising. It is
manufactured by Berkeley Nutritionals,
which is alleged to be the subject of
an investigation by the Attorney
General of Ohio and the defendant in
class-action lawsuits.
Enzyte is a supplement that claims to
increase the male libido or frequency
of erections of the penis. Commercials
for Enzyte are shown regularly on
television. These commercials feature a
man named Bob who never stops smiling,
apparently because he had taken Enzyte
and improved the size of his sex
organs. The commercials are riddled
with symbolic phallic imagery, e.g.
golf clubs, remarkably tall glasses of
iced tea, and a hose spraying barely a
trickle of water (carried by someone
who doesn't use Enzyte).
The effectiveness of Enzyte is in
dispute. Some medical professionals in
fact advise against taking Enzyte,
saying that it can lead to damage. The
Center for Science in the Public
Interest have urged the Federal Trade
Commission to disallow further
television advertising for Enzyte due
to a lack of proper studies supporting
claims. Enzyte maker Berkeley Premium
Nutraceuticals, Inc., is currently
under a class action lawsuit for false
advertising.
