Corpora cavernosa

Corpora Cavernosa is a pair of sponge-like regions of erectile tissue which contain most of the blood in the penis during an erection.

Anatomy

The corpora cavernosa are two areas of erectile tissue on either side of the penis which fill with blood and become rigid during an erection. They are surrounded by a membrane called the tunica albuginea. The corpus spongiosum is a single mass of erectile tissue which lies beneath the corpora cavernosa and surrounds the urethra.

Function

The corpora cavernosa's main function is to facilitate penile erections. During sexual arousal, signals from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the open spaces. The blood creates pressure in the corpora cavernosa, making the penis expand, which in turn compresses the veins that drain blood away from the penis. This process results in an erection.

Clinical significance

Conditions such as erectile dysfunction (ED) and Peyronie's disease can affect the corpora cavernosa. ED is a condition where a man has difficulty getting or maintaining an erection, while Peyronie's disease is a condition where the penis bends or curves due to plaques or hard lumps in the corpora cavernosa.

Treatment

Treatment for conditions affecting the corpora cavernosa varies depending on the specific condition and its severity. Treatments may include medications, surgery, or other medical procedures. For example, in the case of erectile dysfunction, treatments may include oral medications, penile injections, or penile implants.
