Even though the hand is many, many times larger than the clitoris, the median nerve only contains about 18,000 nerve fibers, or fewer than two times the nerve fibers that are packed into the much-smaller clitoris.”While the penis has been widely studied, the vulva — which includes the clitoris, labia majora and labia minora — is poorly understood.The findings could also help reduce accidental nerve damage for patients who undergo an aesthetic procedure known as labiaplasty, which reduces the size of inner flaps of skin on either side of the vaginal opening.The study’s authors are Peters, Maria Uloko, M.D., of University of California San Diego, and E. Paige Isabey, M.D., of University of Manitoba.Matthew D. Wood, Ph.D., and Daniel A.Hunter, both of Washington University School of Medicine, assisted with the study’s nerve analysis."
