The erectile organs of the vulva, through their structure and functionality, participate directly in determining the state of arousal and erection, necessary for sexual intercourse.
The command to trigger an erection is given by the brain and is transmitted through the medullary pathways and/or the sacral spinal cord S2-S4, through the reflex arch.
The direct connection between the cavernous erectile organs containing a venous plexus (vestibular bulbs) with the erectile tissue of the clitoris, the suburethral tissue, respectively the cavernous venous plexus of the urethra which constitutes the Vaginal Area of
Hypereroticism (”H”), stimulates the receptors of any of the above structures in order to increase the local congestion and the vulvovaginal erectile sensitivity, thus activating the desire to mate (the ”libido”).
It has to be mentioned that the erectile tissue covered by albuginea has a special functionality compared to the tissue with simple local hyperemia (Niţescu).
Parasympathetic impulses dilate the arteries of erectile tissue due to acetylcholine, nitric oxide and VIP (Vasoactive Intestinal Polypeptide) released at the nerve endings, local hyperemia highlighting the vulvo-vaginal erectile tissue.
The connections between the corpora cavernosa of the clitoris and the corpora cavernosa of the urethra are also explained by the drainage of venous blood, that is mainly and directly to the circumflex veins, which is another proof of the direct link between the clitoris and H area, all considered by women as being the most important vulvovaginal erogenous zones.
