Logistics of Intracorporeal Injection Therapy for Erectile Dysfunction

This discussion applies to the following medications Bimix, Trimix, Quad-Mix, and prostaglandin preparations including Caverject and Edex.

The preferred site of injection is about one third from where the penis originates.

I usually advise patients to stretch the penis, especially if you are uncircumcised, and then inject the medication while the penis is on stretch.  Usually right-handed men hold the syringe in the right hand and pull the penis to the left to make injections easier.  It is better to inject towards the top then towards the bottom of the penis as as urethra runs on the “bottom” of the penis which you want to avoid.

How the Dose of Injections is Determined:

There is no one dose that is used for everyone. Each man is individually evaluated and an appropriate dose of medication is chosen to provide adequate erection while minimizing the risk of priapism (erection that lasts for > 4 hours). With combination medications such as Trimix, various Trimix preparations are available with various strength, in addition to dose of medication (mL or microliters), the preparation strength is chosen.  Multiple visits may be required to choose the correct dose.

The goal when choosing an appropriate dose is to provide adequate erection hardness and adequate duration.  The duration of erection should be close to or just under an hour.

We have also noticed that some man with ED can benefit sufficiently from 1 injection to be able to skip additional injections for one to two weeks at a time. They are able to achieve adequate erections spontaneously for some period of time after an injection before they need another injection.
