There are many reasons for male circumcision. For circumcised patients, because the glans cannot be exposed for a long time, resulting in a strong secretion of the inner plate of the foreskin and a large amount of foreskin scale stimulation, it is easy to cause inflammation of the foreskin and glans, and if the foreskin and glans is not treated in time, it will also cause adhesion of the foreskin and glans and other situations. Long-term prepuce is likely to cause glans sensitivity, which is clinically manifested as premature ejaculation. For patients with prepuce, the incidence of penile cancer is also higher than normal people. If the foreskin is too long and there is also narrowing of the outer foreskin, this is circumcision, which is more likely to cause the above situation, so it is necessary for circumcised patients to have circumcision.
