Vacuum erection devices can increase penile lenght after 6-12 months of usage. But there is no evidence based studies in this field. Stem cell treatments and P-shot can accelerate this grow-up while using pumps. as I told you before all these procedures are not evidence based. The most effective way to increase penile lenght and girth is "penile enhancement surgery"
Actually PRP is prepation tubes' quality, and quality of materials(like centrifuge) is important for the effect of P-shot. You can search for stem-cell treatment, which is more effective than PRP
In mtf bottom surgery, we use skin of penis or sigmoid colon. For penile skin, the depth is similar to the length of penis
The best way to overcome issues like this is to use of tissue engineering. Fat grafts, dermal fillers all can cause atypical shape. Tissue engineering gives more firm and regular shape
