Penile lengthening is a type of male genital plastic surgery that involves severing the superficial suspensory ligament and the deep suspensory ligament on the penis from their proper locations, separating the cavernous body of the penis and lengthening the penis with no change in the total length of the penis. The procedure is elective and can effectively improve male physiological function and eliminate psychological barriers. Penile lengthening surgery is suitable for people with congenital short penis, less than 6cm when erect or acquired short penis deformity due to trauma, and some patients are determined to request surgery in the clinic. The surgery is contraindicated for patients with scrotal inflammation, poorly controlled diabetes, and coagulation disorders. Penile lengthening surgery can have postoperative complications, penile foreskin edema, penile retraction, hematoma, etc.. To summarize, if you need to perform penile lengthening surgery, you should consult a doctor in time.
