Injuries and other abnormalities of the penis and prepuce of bulls present perplexing problems to the veterinarian. While a few of these conditions may be considered "uniformly" amenable to treatment, the percentage of bulls returned to normal service following surgery for the correction of the more serious conditions is less than is desired. Recent studies of the innervation!,2 and circulation3 have added important contributions to the knowledge of the anatomy of the genitalia of the bull, and should aid the veterinarian in improving surgical techniques whereby a larger percentage of bulls can be reclaimed for breeding purposes.
