PATHOLOGY

Detailed explanation-1: -Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.

Detailed explanation-2: -The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy. Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and open into the urethra above the seminal colliculus.

Detailed explanation-3: -The ejaculatory duct delivers sperm into the urethra, adding secretions and additives from the prostate necessary for sperm function, while providing an interface between the reproductive and urinary systems in men (see image below).

Detailed explanation-4: -What is an ejaculatory duct? Each of your two testicles has a vas deferens that joins with each of your seminal vesicle ducts to form your ejaculatory ducts (EDs). The EDs move through your prostate and pick up prostatic fluid to add to the semen. The fluid empties into your urethra.
