Morphological examination of the accessory sex glands of the Barki bucks (Capra hircus)

Investigation of male genital system anatomy in the New Zealand rabbit ( Oryctolagus cuniculus L. )

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.
