**3. The prepuce (what is removed during circumcision?)**

The glans is covered by the prepuce which is formed of two layers of skin reflected at the neck of the penis behind the corona glandis; the inner layer of the prepuce is confluent along the line of the neck with thin skin-which covers and adheres firmy to the glans on the undersurface of the glans penis, a small median fold passes to the deep surface of the prepuce (frenulurn). The prepuce is separated from the glans by a potential space (preputial sac) which presents two shallow fossae on either side of the frenulum. On the corona glandis and on the neck of the penis, there are numerous small preputial sebaceous glands which secrete smegma beneath the foreskin (a mixture of sebaceous material and shed keratin). It has a peculiar odor, and may be seen exiting from the foreskin tip or accumulate in clumps beneath the foreskin (Gray's Anatomy, 1950).
