Injection Treatments for Impotence A drug is injected directly into the shaft of the penis when you want to have sex. Although it sounds a bit worrying it is easy to learn. The medication usually works within about 15 minutes.
Hormone Treatments for Impotence
Hormonal problems are rarely the cause of impotence. The most common hormone
abnormality is reduced levels of the male sex hormone testosterone.
Testosterone can be restored to a therapeutic level with hormone replacement
therapy.
Oral
testosterone can reduce impotence in some men with low levels of natural
testosterone. Patients also have claimed effectiveness of other oral
drugs--including yohimbine hydrochloride, dopamine and serotonin agonists, and
trazodone--but no scientific studies have proved the effectiveness of these
drugs in relieving impotence. Some observed improvements following their use
may be examples of the placebo effect, that is, a change that results simply
from the patient's believing that an improvement will occur.
Many men
gain potency by injecting drugs into the penis, causing it to become engorged
with blood. Drugs such as papaverine hydrochloride, phentolamine, and
alprostadil (marked as Caverject) widen blood vessels. These drugs may create
unwanted side effects, however, including persistent erection (known as
priapism) and scarring. Nitroglycerin, a muscle relaxant, sometimes can enhance
erection when rubbed on the surface of the penis.
