Urethral sponge

Urethral Sponge

The urethral sponge is a spongy cushion of tissue that surrounds the female urethra. It is part of the female reproductive system and plays a role in sexual arousal and urinary continence.

Anatomy

The urethral sponge is located in the anterior wall of the vagina, surrounding the urethra. It is composed of erectile tissue similar to that found in the clitoris and the corpus spongiosum of the male penis. During sexual arousal, the urethral sponge becomes engorged with blood, contributing to the sensation of sexual pleasure.

Function

The primary function of the urethral sponge is to provide structural support to the urethra and to aid in urinary continence. It also plays a significant role in sexual function, as its engorgement during arousal can enhance sexual sensation and contribute to orgasm.

Clinical Significance

The urethral sponge can be involved in certain medical conditions, such as urethral diverticulum, where a pocket forms in the urethral wall. This can lead to symptoms such as urinary tract infections, painful urination, and dyspareunia.
