It is a very sensitive structure, analogous to the male penis. The innervation of the vulva derives from branches of several nerves, including the ilioinguinal nerve, the genital branch of genitofemoral nerve, the perineal branch of the lateral femoral cutaneous nerve of the thigh, and the perineal branch of the pudendal nerve.

Each is approximately 7 to 8 cm in length and 2 to 3 cm in width. The Clitoris is an erectile structure, homologous with the penis. This knowledge is necessary in order to understand the vulva's physiology and recognize the wide spectrum of vulvar pathology. The remainder of the body is covered by its prepuce anteriorly and frenulum posteriorly, which are derived from the labia minora. Configuration and other anatomic details of the prepubertal hymen.
