Corpus spongiosum

Corpus Spongiosum is a mass of spongy tissue that surrounds the urethra extending from the bulbous urethral to the glans penis. It is one of the three parts of the penis in the male, and in the female, it is a part of the clitoris.

Anatomy

The Corpus Spongiosum is located in the urogenital triangle, the anterior part of the perineum. It is cylindrical in shape and lies along the bottom of the penis, surrounding the urethra. It is smaller than the other two bodies of erectile tissue, the corpora cavernosa, which are located on the top side of the penis.

Function

The primary function of the Corpus Spongiosum is to prevent the urethra from pinching closed, ensuring that the urethra stays open during erection, allowing the passage of semen and urine.

Clinical Significance

Damage or injury to the Corpus Spongiosum can lead to erectile dysfunction or other sexual health problems. Conditions such as Peyronie's disease, which causes abnormal fibrous lumps that lead to a curvature of the penis, can also affect the Corpus Spongiosum.
