Penile Injection Lesson - Nov 24

As planned at the last meeting with Dr. Kawachi, I returned with my injection kit for instructions on proper use.  

The prescribed drug is Trimix, a mixture of three drugs - PGE-1, Phentolamine, and Papaverine.  While the major active ingredient is PGE-1, researchers have found that adding the other two drugs (mainly vascodialators) reduce or eliminate pain some experience with PGE-1 alone.  The ratio of the three can be adjusted if a person still has problems, but most users are fine with the default mixture.

To help get over the fear of sticking a needle in my penis, an autoinjector was included with my supply kit.  It is called an Inject-Erect.  Here is a link to a YouTube video showing how to use the device:

And it is just as simple as the video shows.  There is absolutely no pain.  

The doc loaded the syringe with 0.05ml of Trimix solution.  He said this was probably not sufficient to get a "useable" erection but it should be enough to get a response.  All he wanted to do was demonstrate there was nothing to fear and that the Trimix would indeed work.  And it did.  After about 5 or 10 minutes I had achieved a partial erection (about "1/4 mast" erection).  He was happy with the response.  It was left with me to keep upping the dose over the next several days to achieve the erection I wanted.  Dr. Kawachi suggested I try the next injection in about 24 hours and to be fairly aggressive.  Don't do 0.05ml again, but move on to 0.15ml.

As for frequency, he said that the general guideline was to do no more than 3 injections per week; however, he said this was just a general guide and not to worry about frequency other than to wait at least 24 hours between injections.  Anyway, he said, "Your wife will be the limiting factor regarding frequency."  Kidding aside, he said that the purpose of the injections for the first year or so will be to rehabilitate the penis - not just for intercourse.  Urologists are of the opinion regarding erections that you "use it or loose it".  The longer you go without having an erection, the more difficult it will be to ever have an erection.  And, eventually, you will not be able to have an erection at all.

He did offer a stern warning about an erection that did not go down within about 2 hours.  If that happens I MUST call the hospital for instructions on how to relax the erection.  An erection that lasts more than 6 hours can (will?) cause irreversible damage to the penis.  An erection is the result of blood filing the copra cavernosa lying along both sides of the penis.  The blood is trapped inside during the erection and no new blood flows in or out.  Thus, if the blood stays in place too long, it will begin to clot.  A very bad thing.

I left with a smile and partial erection (and the hope that it would go down by the time I got home - about 2 hours).  Sure enough, it did.

I wait with anticipation for this evening's attempt.
