glans penis

glans penis, rounded, bulbous tip of the penis, the male reproductive organ. The glans forms the most sensitive and distal portion of the penis. It is composed of erectile tissue that is continuous with the corpus spongiosum, and it is covered by a thin layer of skin known as the foreskin (prepuce). In uncircumcised males, the foreskin must be manually retracted to expose the glans.

The surface of the glans is often pink or reddish because of its rich blood supply, and its texture differs from surrounding skin, being more delicate. The glans contains a high density of sensory nerve endings as well, making it an important structure in sexual arousal and stimulation. The opening of the urethra (the urethral meatus) is located at its center, allowing for the passage of urine and semen.

Beyond its sexual and reproductive roles, the glans also has cultural, medical, and anatomical significance. Its appearance can reflect certain health issues, such as infections, dermatological conditions, or systemic diseases.
