At the age of 22, the development of the penis is already set, and even after circumcision, the length of the penis itself will not change, but after retrograde circumcision, the glans will be exposed. It may look visually as if it is bigger. Although circumcision does not increase the size of the penis, after circumcision, it is conducive to the discharge of secretions in the foreskin, reducing the breeding of bacteria and reducing the occurrence of diseases such as glansitis and urethritis. At the same time, it can also improve sexual function to a certain extent, prolong the duration of sexual life, which is more conducive to the harmony of sexual life. In addition, it also makes the appearance of the penis improved and enhances the self-confidence of men. If you do have a short penis, you can also undergo penis lengthening surgery according to your situation. Penis lengthening surgery is currently clinically divided into two types, penile prosthesis implantation surgery and endoscopic minimally invasive surgery. These two types of surgery need to be carried out according to the patient’s specific situation and under the advice of a doctor.
