Corpus Spongiosum of Penis (Corpus spongiosum penis)
Educational content only — not medical advice.
Anatomy
The corpus spongiosum of the penis is a single midline erectile cylinder situated along the ventral groove of the corpora cavernosa. Expanded proximally into the bulb of the penis in the superficial perineal pouch and distally into the glans penis, it is traversed along its entire length by the spongy urethra. Its tunica albuginea is thinner and more pliable, keeping the urethral lumen patent during erection.
Clinical notes
Hypospadias is a common congenital anomaly characterized by incomplete ventral development of the corpus spongiosum and urethra, leaving the external meatus on the ventral shaft or perineum.
