Self-Injection - Erectile Dysfunction

How are the injections administered?

Penile injections should be coordinated by a urologist. Injection treatments involve the injection of medication into the base of the penis (the part of the shaft furthest from the head of the penis) approximately 5-10 minutes before sexual activity. The injected medication causes blood vessels within the penis to widen, or dilate, which increases blood flow to the penis and causes an erection. Erections from injection therapies are commonly 30 minutes in duration. The needle used is a 29-gauge needle (tiny - like that used by diabetics injecting insulin for sugar control). Most men describe the sensation like 'pulling a hair out of the back of their hand'.

Although the thought of an injection can be unpleasant, injection is a quick and easy technique to learn. The injection method is highly successful letting many men experience an erection rigid enough for intercourse. Injections should not be used more than 3 times per week. Patients need to be trained in the technique of penile injections and these training sessions also allow the physician to figure out a safe starting dose of injection medication.

It is always best to speak with a physician or trained health professional to discuss the proper use of any prescribed treatment.
