Male prepuce is a condition in which the glans is not completely separated from the foreskin and completely wraps around the glans after reaching adulthood, which has a probability of less than 1%. After birth and until the age of three, men have physiological prepuce, which does not require special treatment. As the body grows and develops, the adhesions between the foreskin and glans will gradually loosen and gradually return to the coronal sulcus. If a man still has foreskin wrapped around the glans after he becomes an adult, it is a case of prepuce, but the incidence of the disease is low, and it is a case of hypospadias, where the foreskin is able to retreat to the coronal sulcus to expose the glans, but then completely wraps around the glans when it is weak. For men with prepuce, it is recommended that they should undergo surgery in time for adulthood, because prolonged prepuce can stimulate the local glans mucosa to produce undesirable lesions, and even the risk of penile cancer.
