What treatment plan would you suggest in treating a waist in the penis? And also, does the penis waist happen because of lack of blood flow to that area?
When you mention a "waist in the penis" I assume you refer to what is commonly referred to as an hourglass deformity of the penis associated with Peyronie's disease in which there is a narrowed portion of the penis in a small or large part of the circumference of the shaft.
Treatment for this type of distortion is not much different for this distortion or for any other distortion that is caused by the presence of the internal Peyronies plaque or scar tissue – except in one small aspect I will explain a bit further down. The very important point I want to make now is that good Peyronies treatment is not directed to the distorted (bent, curved, hourglass, waisted, limp or shrunken) penis, but to the scar itself. What is wrong with you is not that your penis has a waist formation, but that you have a Peyronie's plaque or internal scar in the shaft that is causing a waist formation. Do you understand the critical point I am trying to make? Your problem is not the waist, but what is causing the waist to form. That is why it is pointless to try to stretch a curved penis with a mechanical penis stretcher because it cannot do anything to remove or reduce the Peyronies plaque. A case of Peyronie's disease is not a curved penis that will be corrected by forced stretching, like a bent paperclip. A case of Peyronies disease is one in which internal scar tissue can cause the penis to bend or distort in some way. For this reason treatment is not so much directed to the kind of distortion but to the reason for the distortion.
Having explained that, I will say that the gentle manual penis stretching technique developed in a PDI research project a few years back can be modified to suit the type of distortion displayed because with this particular local technique it is possible to focus subtle traction vectors into the specific location and direction of the plaque formation. We developed unique techniques for bends, twists or rotation, hourglass, bottleneck and combinations of deformities to isolate the fibers that cause those patterns in an effort to stimulate their reabsorption.
This waist or hourglass type of distortion is caused by a circular or collar-like Peyronie's plaque formation that either prevents or restricts the full expansion of the shaft during an erection or allows blood to not collect in a particular area and therefore not expand completely.
My suggestion is that you do a bit of reading at start Peyronie's treatment to see if this makes sense to you, and to begin working to increase your ability to heal the Peyronies scar in the best way possible. In my opinion the best Peyronie's treatment is the largest and most aggressive you can sustain for a few months to assist natural healing. Read the PDI website to learn if you agree. TRH
