Normally, male genitals do not thicken naturally as they enter adulthood. Surgical thickening is possible if necessary. The development of male genitals reaches its peak during puberty and usually stops around the age of 18 to 20. The length and diameter of the penis are basically fixed, and there is usually no more natural development and no thickening. If the diameter of the penis is greater than 3 centimeters and the length is greater than 9 centimeters after erection, it is normal. If the patient has an abnormal penis value, there are conditions such as penile dwarfism. After consulting a doctor to confirm the diagnosis, for patients who really need treatment, surgical thickening is available. The main principle of the current surgery is to place a prosthesis or support within the penile tissue to achieve penile enlargement. However, there are risks associated with surgery, including wound infection, bleeding, displacement of the prosthesis, and penile deformity. To summarize, if you feel uncomfortable, seek medical attention promptly.
