Detailed explanation-1: -This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac. The vas deferens is between the epididymis and the urethra and connects these together.

Detailed explanation-2: -Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.

Detailed explanation-3: -The ductus deferens, or vas deferens, is a fibromuscular tube that is continuation of the epididymis and is an excretory duct of the testis. Each ductus is 30-45 cm in length and serves to transport sperms cells from the respective epididymis to the ipsilateral ejaculatory duct.

Detailed explanation-4: -A coiled tube that carries the sperm out of the testes.

Detailed explanation-5: -Mature sperm begin their journey by travelling from the epididymis to the vas deferens, which propels sperm forward with smooth muscle contractions. The sperm arrive first at the ampulla just above the prostate gland. Here, secretions from the seminal vesicle located next to the ampulla are added.
