Men can have penis lengthening surgery at the age of 35. Penile lengthening surgery is generally applicable to adult males with erectile length <10cm, congenital shortness of the penis or shortness and deformity of the penis due to acquired trauma, burns and so on. Penile lengthening is a surgery that cuts off the superficial suspensory ligament on the penis and separates the corpus cavernosum of the penis that is buried in the perineum, thus enabling the appearance to be lengthened by 3 to 5cm. Men who are dissatisfied with their length and have an unhappy sex life can volunteer for this procedure, but the total length of the penis will not change after the procedure. For men whose penis length is in the normal range, it is recommended not to have the surgery, and also to avoid the surgery for those who have inflammation in the penis scrotum, those with blood clotting disorders, and those who have uncontrolled diabetes mellitus.
