Anatomic and topographical features of the reproductive organs in rabbits according to X-ray studies

The purpose of research is to study the anatomical and topographical features of the testis, epididymis, and vas deferens in Californian breed rabbits. The studies were carried out at the Department of Anatomy, Histology, Physiology and Pathological Anatomy and the University Veterinary Clinic of the Federal State Budgetary Educational Institution of Higher Education Omsk State Agrarian University using the X-R StaticExamionclassic X-DR XL digital radiographic system. The objects of the study were sexually mature male rabbits. According to X-ray studies, the testis is visualized as an elongated oval-shaped formation. When located in the testicular sac, the right testis is localized at the level of the middle third of the second caudal vertebra to the cranial third of the seventh caudal vertebra, and the edge of the capitate end of the left testis is displaced to the cranial third of the second caudal vertebra. In the abdominal cavity, the right testis is localized at the level from the middle third of the sixth lumbar vertebra to the iliopubic eminence. The left testis is displaced to the cranial third of the seventh lumbar vertebra. The epididymis of the testis on the radiograph appears as a conical formation, tapering towards the caudate end with a large number of curls. The ductsdeferentis have a complex, tortuous course. Coming from the tail of the appendage at the level of the second caudal vertebra, they turn each at an obtuse angle, follow to the cranial third of the body of the iliac bone of the pelvis, where they turn sharply at an acute angle, follow laterally, then caudally, uniting with the excretory duct of the vesicular gland into the ejaculatory canal. Both ducts open into the urogenital canal near the seminiferous colliculus. The length of the right testis and its appendage is 3.63 ± 0.06 cm, width - 1.70 ± 0.10 cm, cross-sectional area of the testis and its appendage - 4.56 ± 0.24 cm2. The length of the left testis is 3.62 ± 0.13 cm, width - 1.67 ± 0.17 cm, cross-sectional area of the testis and its appendage - 4.26 ± 0.15 cm2. The length of the right vas deferens was 7.57 ± 0.11 cm, the length of the left vas deferens was 7.45 ± 0.07 cm.
