What kind of dingus is normal? Why do many men have such a need? The length and circumference (thickness) of the penis are affected by many factors, including genetics, ethnicity, hormone levels during puberty, and the presence or absence of a foreskin, while some congenital disorders, such as hypospadias, cryptorchidism, and micropenis, can also result in a short penis, and may even affect the patient’s normal sex life in adulthood. These disorders have their own pathogenesis and treatment modalities, and are not the subject of today’s discussion. As a healthy adult with normal development, if you realize that your penis is short, it will often affect your self-confidence and the quality of your sex life in the future, causing depression and seriously affecting the quality of life of yourself and your partner. Therefore, penis lengthening and enlargement surgeries are getting more and more attention. Is there a scientific basis for penis lengthening and enlargement surgery? What are the general types of surgeries? From a medical point of view, all kinds of penis lengthening surgeries involve cutting the superficial suspensory ligament of the penis, thus releasing part of the cavernous tissue of the penis that is originally “buried” underneath the skin, in order to achieve the purpose of lengthening the penis. According to the patient’s preference and local conditions, the surgery can be carried out through the root of the penis or the head of the penis coronary groove incision, usually, after the operation, the static length of the penis can be extended by 2-4cm compared with the preoperative. some friends due to the weight of the body weight is a little big, there is a fat accumulation in the area of the mons pubis, which can visually create the illusion of a short penis, the problem can be resolved through physical exercise or liposuction of the mons pubis method. Penis enlargement, on the other hand, can be done in the following ways. Abdominal dermal fat flap filling. The surgery starts with cutting a portion of fat tissue with dermis from the patient’s abdomen, which is then trimmed and filled between the penile skin and the corpus cavernosum to achieve the purpose of thickening. The results of this procedure are precise and reliable, and there is no absorption of the filled tissue or tissue rejection in the long term. However, its disadvantages are also more obvious. First, the procedure is long and requires hospitalization, with a relatively long postoperative recovery time; second, the procedure causes abdominal scarring; and third, after erection, there will be a unique appearance of the front part of the penis being fuller while the partner portion is thinner, resulting in visual unpleasantness. Decellularized Allogenic Dermal Fillers. This procedure involves placing a thicker piece of decellularized allogeneic dermis between the corpus cavernosum and the skin of the penis, and due to the thickness of the dermis, a thickening of the penis can occur after the procedure. The advantages of this procedure are that it takes less time to perform, does not require hospitalization, and can be completed on an outpatient basis; the decellularized allogeneic dermis is histocompatible, and complications are rare; and studies have shown that because the allogeneic dermis covers the dorsal nerves of the penis, it plays a certain isolation role, and also has a better therapeutic effect on some cases of premature ejaculation. The shortcomings of this procedure are similar to those of the previously mentioned dermal fat flap filler in that there may be an anteriorly thick and posteriorly thin appearance of the penis after erection, and for patients who did not have premature ejaculation prior to the procedure, a decrease in sensory sensitivity of the penis may occur after the procedure. Penile autologous lipofilling, the procedure is to suck a certain amount of autologous fat from the patient’s thighs or abdomen, and then inject it into the subcutaneous tissue between the cavernous body of the penis and the skin after separating and purifying it. The surgery can be carried out under local anesthesia without hospitalization, and the result is precise, and since the fat is autologous tissue, tissue rejection is unlikely to occur. The shape of the penis is more natural after the operation, and the appearance of thicker in front and thinner in the back is rarely seen after erection. However, since there is a certain percentage of absorption and liquefaction rate after autologous fat filling, 2-3 times of fat filling treatment is usually required to achieve more satisfactory results.
