Penile lengthening has the effect of lengthening the extracorporeal portion of the penis, and can be used to improve the treatment of congenital penile shortening as well as partial penile defects caused by acquired factors. Penile lengthening is a tertiary surgical procedure that is difficult, risky and complex. Penile lengthening can be standardized for adult men with congenital penile shortening, partial penile loss due to surgical trauma, or if there is a need for penile lengthening in the absence of other psychological disorders. Although penile lengthening can increase the length of penile activity, the surgery itself has a certain risk, and the results obtained after the surgery will be due to the actual condition of the individual as well as the physical condition of the existence of variability, careful consideration should be made before the surgery, and fully communicate with the doctor.
