vas deferens
vas deferens The tube on each side which leads from the testis to the urethra, carrying sperm and some other components of seminal fluid. Each vas ends by joining the duct of a seminal vesicle, to enter the urethra (the urinary passage) where that traverses the prostate gland. May be closed off by the operation of vasectomy, preventing sperm from entering the ejaculate.
Stuart Judge See urogenital system. |
