A corpus cavernosum penis (singular) (cavernous body of the penis) is one of a pair of sponge-like regions of erectile tissue the corpora cavernosa (plural) (cavernous bodies) which contain most of the blood in the penis during an erection. Such a corpus is homologous to the corpus cavernosum clitoridis in the female; the body of the clitoris contains erectile tissue in a pair of corpora cavernosa (literally cave-like bodies) with a recognisably similar structure.
