Arterial supply to the rabbit male genital organs

The improvement of veterinary care has prolonged the lifespan of rabbits, and the number of rabbits suffering from age-related, male genital disorders may increase in the near future. This could result in increased opportunities for male genital surgery, requiring knowledge of their arterial anatomy...

description The improvement of veterinary care has prolonged the lifespan of rabbits, and the number of rabbits suffering from age-related, male genital disorders may increase in the near future. This could result in increased opportunities for male genital surgery, requiring knowledge of their arterial anatomy, which, however, has not been sufficiently studied. Therefore, the arteries supplying the genitals were observed in 20 male New Zealand White rabbits. The testis was supplied by the testicular artery originating from the abdominal aorta. The right testicular artery usually emerged at a more cranial level than the left artery (65%). The testicular artery encircled the testis in the sagittal plane and bifurcated (95%) or trifurcated (5%) at the caudal extremity of the testis before entering the parenchyma. The epididymis was supplied by the epididymal branches, either from only the testicular artery (75% of the right and 80% of the left halves) or from both the testicular artery and aorta. The deferent duct was supplied in all halves by the dorsal and ventral branches of the deferential artery, which usually arose from the umbilical artery. The accessory genital glands were supplied by the dorsal branch of the deferential artery and the prostatic artery. The latter, which emerged from the internal iliac artery, exhibited 3 branching types. The most frequent type (55% of the right and 45% of the left halves) had 3 branches supplying the accessory genital glands. These findings will help improve rabbit genital surgery.
