If it is due to a lack of sex hormones, the penis can be enlarged by supplementing the sex hormones and solving the primary cause of the disease. If a man’s genitals are too small in adulthood, they can only be enlarged through surgical methods, such as penile lengthening and enlarging surgery and penile prosthesis implantation, but since the surgical techniques are not yet very mature, the results of the surgery may not be very satisfactory.
