| Foreskin refers to a fold of skin covering the glans . By eversion of the foreskin, one may see the circular small part below the glans known as coronary sulcus. There are many sebaceous glands in the skins surrounding the coronary sulcus, excreting a yellowish- white mud-like stinky secretion, known as ”°smegma”±.
Phimosis refers to that the opening of the foreskin is too small unable to evert the foreskin to expose the glans; redundant prepuce refers to that the foreskin covers the whole glans, but the opening of the foreskin is not small which is able to expose the glans by eversion of the foreskin. Long foreskin in infants and children is usually physiological, however, only the inability to expose the glans after adolescency is known as phimosis and redundant prepuce. |
