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. This fluid is what carries sperm outside of your body when you ejaculate because of sexual arousal.
