glans penis

The glans penis is the rounded, sensitive head at the tip of the penis. It is covered by a fold of skin called the foreskin in uncircumcised males. The glans contains many nerve endings, making it highly sensitive to touch and stimulation. It plays a key role in sexual pleasure and is involved in the processes of urination and ejaculation. The skin of the glans is usually smooth and more delicate than the shaft of the penis, and it helps protect the tip while also serving as a center for sensation.
