Hmmm, I'm not thinking breast enlargment is and equal comparison.

"Lengthening procedures are performed under general anesthesia. Incisions are made at the root of the penis where it joins the pubic area. The penis is then released from its attachments (suspensory ligaments) to the pubic symphysis. The space is closed with local tissue. Skin from the penis and/or the pubic area is used to cover the new extended penis. Post-operative traction using weights reduces the chance of retraction and provide more natural shaft skin....
Many doctors will also recommend manual stretching at one week and a weight program, where post surgery, weights or another traction method are hung from your penis to sustain and increase the length. Weights are used at two weeks for a lengthening procedure only, or three weeks for fat autografts, and four to five weeks for derma fat grafts or flaps. Some patients maintain traction for up to 6 months after surgery, which will reduces the chance of retraction, stretch the shaft skin and in some cases results in further lengthening by stretching tissues which could not be cut at surgery. Scars may take many months to fade and soften."
