The corpus cavernosum of clitoris is one of a pair of sponge-like regions of erectile tissue which contain most of the blood in the clitoris during clitoral erection. The perineal membrane defines the openings of the urethra and the vagina. This results in dilation of these arteries and erection of the penis or clitoris. Glycogen, stored in the epithelial cells, reaches maximal levels at ovulation after which time the glycogen-rich superficial layer of epithelium is shed. The corpora cavernosa of the clitoris measures up to 5 inches in length. During arousal to orgasm, the few records obtained show an increasing vaginal lumenal pressure [40].
