Circumcision does not enlarge the penis. The foreskin is the skin that surrounds the glans. When the foreskin is too long or circumcised, circumcision can expose the glans to avoid infections, etc., but circumcision will not enlarge the penis. Penile development is generally faster during puberty, mainly related to the level of androgens in the body, and stops after adulthood. Therefore, during puberty, we should pay attention to replenish all kinds of nutrients to avoid the phenomenon of stunted growth. If you suffer from certain diseases that lead to insufficient secretion of androgen in the body, such as testicular deficiency, etc., you can timely replenish androgen, or it will easily lead to penile shortening. If the patient is not feeling well, he should consult the doctor for examination and early treatment.
