From peyronies disease forum:
"Many people ask for my advice about a ‘penis pump.’ Here is the basic problem with the VED (Vacuum erection devices): You and I have both definitely proven that we have penile tissue that is susceptible to injury and when injured (and even when not injured), we can develop an excess scar reaction. If you injure the penis by over-stretching, as is easy to do since there is no way to know at what point is the point of over-stretching, you will create more Peyronies plaque material. Most men will probably over use the VED just because they get excited when they see the results the device can produce temporarily. If you are prone to Peyronie’s disease anyway, this kind of tissue stretching can be a disaster. The only way you can safely use a VED is to not over use it; the problem is there is no way to know what is over use and abuse until it is too late."
"In my time communicating with men who have Peyronie’s disease, I have found a surprisingly large percent of them who state their initial injury that resulted in their Peyronies can be traced back to use of a VED. These are the men who started out simply wanting to increase their penile dimensions, and injured themselves to the point that Peyronie’s disease developed. While there are a few men who say a VED helps them, there are many more who say it does not."
And on the other side suggesting benefits of VED in peyronies there is this study:
"CONCLUSION Vacuum therapy can improve or stabilize the curvature of PD (peyronies disease), is safe to use in all stages of the disease, and might reduce the number of patients going on to surgery."
