      either of two hollow tubes, each formed by union of the ampulla of a ductus deferens (q.v.) and the excretory duct of a seminal vesicle (q.v.). The ducts, which open into the urethra about halfway through the prostate gland (q.v.), function to mix the sperm stored in the ampulla with fluids secreted by the seminal vesicles and to transport these substances to the prostate.
