Corpus spongiosum (penis)

Corpus Spongiosum is a mass of spongy tissue that surrounds the urethra within the penis in the male, and aids in ejaculation.

Anatomy

The Corpus Spongiosum is cylindrical in shape and begins at the bulb of the penis, extends along the underside of the penis and ends at the glans penis. It is surrounded by a layer of connective tissue known as the tunica albuginea. The urethra runs through the center of the corpus spongiosum, allowing for the passage of semen and urine.

Function

The primary function of the Corpus Spongiosum is to prevent the urethra from pinching closed, ensuring that semen and urine can be expelled. It also contributes to the rigidity of the erect penis and protects the urethra from potential injury during sexual activity.

Clinical significance

Conditions that can affect the Corpus Spongiosum include Erectile Dysfunction, Peyronie's Disease, and penile cancer. Treatment options vary depending on the specific condition and can range from medication to surgery.
