“…In all rabbits examined, the testis received its arterial supply via the testicular artery, in agreement with prior studies [1,4,5,10,14,18]. In the present study, the right testicular artery arose at a more cranial level than the left artery in 65% of cases, and in the remaining 35% of cases, the left testicular artery emerged at a more cranial level than the right one.…”

“…In the present study, the right testicular artery arose at a more cranial level than the left artery in 65% of cases, and in the remaining 35% of cases, the left testicular artery emerged at a more cranial level than the right one. Arredondo et al [1] also reported that the right testicular artery emerged more cranially than the left one in 83% of cases, whereas the left testicular artery originated more cranially than the right one in 10% of cases. The incidence of the combination of the right and left testicular arterial branching level in the study of Arredondo et al [1] is almost consistent with the present findings, but they also reported cases (7%) where the right and left testicular arteries arose at the same branching level.…”

“…In prior studies in rabbits, the arterial supply to the rabbit male genital organs, such as the testis, epididymis, deferent duct, and accessory genital organs, was poorly described [1,4,5,10,13,14,18]. The testis is supplied by the testicular artery, which emerges from the abdominal aorta.…”

“…For example, Rajtová and Danko [14] reported that the right testicular artery originated at a more cranial level than the left one, while Krause [10] reported that the left testicular artery arose at a more cranial level than the right one. Moreover, Arredondo et al [1] reported cases where the right testicular artery emerged at a more cranial level than the left one (83%), cases where the left testicular artery emerged at a more cranial level than the right one (10%), and cases where the right and left testicular arteries originated at the same branching level (7%).…”

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.

“…In the rare case reported here, however, the cranial mesenteric artery only gave rise to the caudal pancreaticoduodenal, jejunal and ileal arteries, whereas the caudal mesenteric artery gave origin to the ileocecocolic, middle colic, right colic, left colic and cranial rectal arteries. Although prior rabbit studies have not reported this untypical branching pattern [2,6,7,9], Abe et al [1] and Covanțev et al [4] reported a similar case in humans, in which the cranial mesenteric artery supplied the proximal small portion of the ascending colon and cecum [1], or cecum only [4] via the ileocecal artery. Furthermore, they also found that the caudal mesenteric artery supplied most of the colon via the right colic, cranial left colic and caudal left colic arteries [1], or via the right colic, middle colic, accessory middle colic, left colic and accessory left colic arteries [4].…”

The rabbit intestinal tract is supplied by the cranial and caudal mesenteric arteries. Generally, the cranial mesenteric artery supplies the duodenum, jejunum, ileum, cecum, proximal colon and ascending and transverse distal colon, whereas the caudal mesenteric artery supplies the descending distal colon and rectum. The present study describes an abnormal branching pattern of the cranial and caudal mesenteric arteries in a Japanese White rabbit, where the caudal mesenteric artery but not the cranial mesenteric artery supplied the distal ileum, cecum, proximal colon and ascending and transverse distal colon. Such a rare mesenteric arterial ramification pattern may be explained by anomalies of the remaining anastomotic branches between the primitive mesenteric arteries and regressed their parent arteries during the developmental process.

Rabbits are frequently used in research because of their human-like biological structure. In the present study, 10 male rabbits were preferred. Arterial vascularization of the genital system organs were dissected. Morphometric and macroanatomical results of these organs were taken, and some organs were examined by magnetic resonance imaging (MRI). In this study, right testis length was measured at 67.24 ± 5.36 mm and left testis length was 62.25 ± 6.55 mm in New Zealand rabbits.Testicular weight was 10.21 ± 1.17 g on the right and 9.90 ± 1.15 g on the left. Right caput epididymidis 0.68 ± 0.08 g, left caput epididymidis 0.80 ± 0.13 g; right corpus epididymidis 0.14 ± 0.03 left corpus epididymidis 0.15 ± 0.03 g; right cauda epididymidis 1.87 ± 0.26 g left cauda epididymidis 1.90 ± 0.31 g. In the present study, right ductus deferens weight was 0.30 ± 0.29 g, and left ductus deferens weight was 0.25 ± 0.03 g; the ampulla ductus deferentis weight was 0.35 ± 0.16 g on the right side and 0.37 ± 0.16 g on the left side. The length of the vesicular gland glandula vesicularis was calculated as 18.54 ± 0.35 mm on the right and 17.55 ± 0.59 mm on the left. The width of the vesicular gland was measured as 16.54 ± 0.28 mm on the right and 16.70 ± 0.45 mm on the left. Vesicular gland weight was 0.91 ± 0.07 g on the right side and 0.96 ± 0.09 g on the left side. The prostate length was recorded as 11.68 ± 2.01 mm and width as 13.02 ± 1.38 mm. The length of the bulbourethral gland was 13.36 ± 2.00 mm on the right side and 12.39 ± 1.21 mm on the left. Its width was recorded as 6.73 ± 0.98 mm on the right and 5.80 ± 0.90 mm on the left. Respectively, it weighed 0.40 ± 0.20 g on the right and 0.44 ± 0.24 g on the left. The prostate consisted of three parts in rabbits: the proprostate, the corpus prostate and the paraprostate. The bulbourethral gland was a green lentil-sized gland found in pairs. It is thought that the obtained results will contribute to the scientific researches on male genital system in laboratory animals and other animal species, artificial insemination studies, reproductive system diseases and operations in rabbits.
