Anatomical terminology

The corona of glans penis or penis crown refers to the rounded projecting border that forms at the base of the glans in human males. The corona overhangs a mucosal surface, known as the neck of the penis, which separates the shaft and the glans.[1] The deep retro-glandular coronal sulcus forms between the corona and the neck of the penis.

The corona and the neck are highly vascularized areas of the penis. The axial and dorsal penile arteries merge together at the neck before entering the glans.[2] Small venous tributaries deriving from the corona drain the glans foming a venous retro-coronal plexus before merging with the dorsal vains.[3] The circumference and the underside of the corona are densely innervated by several types of nerve terminals and are considered by males an erogenous area of the glans.[4][5]

In some males, small skin-colored bumps, known as pearly penile papules, may appear at the circumference of the corona. Their appearance may vary from being hardly noticeable in some men to more prominent and well-defined in others. The papules are painless, harmless and non sexually transmitted.[6] They usually appear in late puberty and are thought to disappear with age.[7] Even though they do not require treatment, they can easily be removed, especially for aesthetic purposes.[8]
