Glans penis
The glans penis is the sensitive tip of the penis. It is wholly or partially covered by the foreskin, except in males who have been circumcised where the glans is fully exposed. The normal foreskin is retracted during sex or masturbation to expose the glans penis.
Anatomical details
The glans penis is the expanded cap of the corpus spongiosum. It is moulded on the rounded ends of the corpora cavernosa penis, extending farther on their upper than on their lower surfaces. At the summit of the glans is the slit-like vertical external urethral orifice. The circumference of the base of the glans forms a rounded projecting border, the corona glandis, overhanging a deep retroglandular sulcus, behind which is the neck of the penis.
