Spongiosum

Spongiosum

The spongiosum is a spongy tissue found in the male reproductive system. It is also known as the corpus spongiosum. This tissue is an important component of the penis, along with the two corpora cavernosa. The spongiosum surrounds the urethra, which is the tube that carries urine and semen out of the body.

Structure

The spongiosum is made up of a network of blood vessels, smooth muscle, and connective tissue. It is located on the underside of the penis and extends from the base to the tip. The spongiosum is responsible for maintaining the shape and rigidity of the penis during an erection.

Function

During sexual arousal, the spongiosum fills with blood, causing the penis to become erect. The spongy tissue helps to trap the blood within the penis, allowing for sustained rigidity. In addition, the spongiosum also plays a role in the ejaculation process by helping to propel semen through the urethra.

Clinical Significance

In some cases, the spongiosum can be affected by medical conditions such as urethral strictures or infections. These conditions can cause pain, difficulty urinating, and other symptoms. Treatment for spongiosum-related issues may include medications, procedures, or surgery, depending on the underlying cause.
