What is the function of the vas deferens?

Vas deferens is the tube that leads from the epididymis to the urethra in males and runs approximately 40 centimeters. When sperm leave an epididymis, they enter a vas deferens. The vas deferens transports and stores sperm. It must be noted that the length of the vas deferens is used to store sperm for several months.

Its position and its function as a sperm transport vessel make vas deferens a prime candidate for sterilization surgery, which is known as vasectomy (cutting the vas deferens)

there is a technical mistake
"as vas deferens length generally runs to 30-35 cm and opens in urethra where it combines with seminal vesicles duct to form ejaculatory duct"
"They don't store sperms, they only carry it"

The vasa deferns is a continuation of cauda epididymis which leaves the scrotal sac and enters abdominal cavity through inguinal canal.

It loops over the urinary bladder where it is joined by duct from seminal vesicles to form the ejaculatory duct.

They ONLY carry sperms from cauda epididymis to the ejaculatory duct.

Present in 2 in number in a human male, they are thick tubules from the vasa efferentia and its lining consitutes STEREOCILLIA.

It works like important bridge for sperm movement to ejaculatory duct, this makes vasa deferentia a important site for surgical population control method commonly called vasectomy i.e, cutting and tieing the vas deferentia.

Note: Fellow students do take a look at major differences between vasa efferentia and vasa deferens.
