Glossary Term:


neurovascular bundles




groups of nerves and blood vessels that run along each side of the prostate and help the penis become erect. Removal or injury of these bundles during surgery, or damage from radiation therapy, can lead to impotence. Women also have these nerve bundles that run along both sides of the vagina and affect erectile tissue in the genital area. See also impotence, nerve-sparing prostatectomy, prostate.
