Fat-Grafting in the Penis
Penis fat grafts usually tend to be absorbed starting 3 months after initial injection. The loss can range from 30 to 100%, which is mostly associated with severe skin scarring and adhesion, as well as a “lumpy-bumpy” deformity.
The average survival rate of transferred fat tissue, as reported by physicians performing penile fat tissue procedures, is somewhere close to 30%. That means to say that, after several months, only 1/3 of the transferred fat remains.
Transferred fat being absorbed almost instantly requires touch ups every few months in order to maintain size and aesthetically acceptable proportion. When transferred again, the same risks and complications are expected to occur.
How does the Penis Look and Feel After Fat Injection?
While after the initial injection a noticeable amount of girth increase is observed, the look of the treated penis usually depends on the amount of transferred fat tissue, the survival rate, amount of fat cell necrosis, and the extent of fibrosis and scarring causing adhesions. The injected fat is located between the penile skin and the penile erectile tissue (corpora cavernosa), acting as a soft fat cushion. The feel to the touch of a fat injected penis is usually described as “marshmallow” like with a soft consistency, which does not change much upon erection.
”The American Urological Association (AUA) and the Urology Care Foundation consider subcutaneous fat injection for increasing penile girth to be a procedure which has not been shown to be safe or efficacious.”
Board certified urologists do not perform penile fat injection procedures.
