Glans penis

The glans penis, commonly referred to as the glans, is a structure at the distal end of the penis in male mammals.

It is the sensitive bulbous structure at the end of the human penis, and is anatomically homologous to the clitoral glans of the human female.

The glans penis may be smooth, spiny, elongated, or divided in other mammals.

Typically, the glans is completely or partially covered by the foreskin in humans, except in those who have been circumcised.

The foreskin can generally be retracted over and past the glans, and may automatically retract during an erection.

The glans is more commonly known as the "head" or the "tip" of the penis.

The medical name comes from the Latin words glans ("acorn") and penis ("of the penis").
