Ductus Deferens. The ductus deferens, also known as the vas deferens, is a tiny muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct.he ductus deferens serves dual functions in the male reproductive system: 1  Transporting sperm from the testes to the ejaculatory duct and urethra. 2  Storing sperm until it is ready to be ejaculated.
The ductus deferens runs medial to the seminal vesicle and enlarges and terminates into a sacculated structure called the ampulla of the ductus. The ampulla attenuates at the base of the prostate and merges with the seminal vesicle duct to form the ejaculatory duct.
