PATHOLOGY

Detailed explanation-1: -The vas deferens (singular) is also called a ductus deferens or a sperm duct. This long muscular tube runs from the epididymis into the pelvic cavity behind your bladder and connects to your urethra through a structure called the ejaculatory duct.

Detailed explanation-2: -Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.

Detailed explanation-3: -The ductus deferens is 5–6 cm in length, and runs in the spermatic cord from the tail of the epididymis to join the urethra as it passes through the prostate gland. As the ductus approaches the prostatic urethra it widens into an ampulla, where the ducts of the seminal vesicles join the ductus.
