In cat,The ductus deferens also called the vas deferens leaves the tail of the epididymis along with the testicular vessels and nerves, enters the spermatic cord. The spermatic cord enters the abdominal cavity, it contains the ductus deferens, blood vessels and nerves. The site of passage through the body wall is known as the inguinal canal. The ductus deferens of the opposite sides then converge and soon enter the urethra, which leads to the penis. Various accessory glands, which secrete the seminal fluid, are associated with the ends of the ductus deferens and adjacent part of the urethra. In the cat, a small prostate gland surrounds the point of entrance of the two ductus deferens and the adjacent urethra. At the caudal end of the pelvic canal, a pair of Cowper´s glands enter the urethral canal, but the male cat does not have a seminal vesicle as does the human male. In human , From the epididymis, the ductus deferens ascends posterior to the testes and enters the spermatic cord that connects the testes to the rest of the body. It continues with the spermatic cord,and entering the pelvic body cavity at the inguinal canal. Between the ureters and the prostate, the ductus deferens expands its diameter considerably in a region known as the ampulla before narrowing and joining with the seminal vesicles at the ejaculatory duct inside the prostate. The seminal vesicles are a pair of glands that are positioned below the urinary bladder and lateral to the vas deferens. Each vesicle consists of a single tube folded and coiled on itself, with occasional diverticula in its wall. The excretory duct of each seminal gland unites with the corresponding vas deferens to form the two ejaculatory ducts, which immediately pass through the substance of the prostate gland. The seminal vesicles secrete a significant proportion of the fluid that ultimately becomes semen. The vesicle produces a substance that causes the semen to become sticky and jelly-like after ejaculation. The thick secretions from the seminal vesicle contain proteins, enzymes, fructose, mucus, vitamin, phosphorylcholine and prostaglandins.
