Uterus Masculinus or Utriculus Prostaticus of Male Animals The uterus masculinus is a rudimentary structure and a remnant of the paramesonephric (Müllerian) duct in males. It is located between the ampullae and the seminal vesicles, positioned on the caudal-dorsal surface of the urinary bladder, and cranial to the prostate gland. This structure is present in approximately 50–70% of bulls. Species Variations of the Uterus Masculinus

It is at first, pursues a very tortuous course upwards along the caudal border of the testicle. It then becomes straight and runs in the
Decent of testes in Animals During early fetal life, the testicles are situated against the dorsal wall of the abdomen in contact with the visceral surface of the kidneys, these testes descend in animals scrotum to fully function. They are attached to the sub – lumbar region by a fold of peritoneum – the mesorchium
Tunica Vaginalis of Animals Tunica vaginalis of Animals is an evagination of parietal peritoneum passing through the inguinal canal into the scrotum. When fully developed, it has the shape of a flask with narrow proximal part and a distended distal part The proximal part contains the spermatic cord and the distal part has the testis and epididymis. Like the
