In the male, it penetrates the perineal membrane and provides blood to the urethra and nearby erectile tissue to the glans.[3] In the female, the urethral artery serves the analogous structures. Because the female urethra is so much shorter than the male, this structure is often impossible to find on a female cadaver.
