They are called the "neurovascular bundles of Walsh," and they are the tiny, very fragile bundles of nerves that are responsible for erection. "Ever since Patrick Walsh’s discovery of these bundles and his subsequent demonstration of how to spare them during radical prostatectomy, there has been hope for men wishing to regain potency after surgery," says urologist Christian Pavlovich, M.D. "However, even with meticulous nervesparing technique, there are still some men whose erectile function does not recover fully after radical prostatectomy."
