Definition of corpus spongiosum in US English:

corpus spongiosum

nounPlural corpora spongiosa

  • A mass of erectile tissue alongside the corpora cavernosa of the penis and terminating in the glans.

    • ‘These include the corpus spongiosum, which enlarges distally into the glans penis; parallel with, and dorsal to, the corpus spongiosum are the paired corpora cavernosa, which extend distally to the glans.’
    • ‘This technique relies on the absorption of medication through the urethral mucosal lining into the surrounding corpus spongiosum, with passage via small vascular channels into the main erectile bodies, the corpora cavernosa.’
    • ‘The corpus spongiosum is a chamber that surrounds the urethra and becomes engorged with blood during an erection.’
    • ‘The penis consists of two parallel cylinders of erectile tissue, the corpora cavernosa, and a smaller, single ventrally placed cylinder, the corpus spongiosum, which surrounds the urethra and distally forms the glans penis.’
    • ‘The glans penis is the preferred site of application since the medication can enter the corpus spongiosum directly and then be absorbed much like drugs delivered into the urethra.’


From corpus and Latin spongiosum, neuter of spongiosus ‘porous’.
