An average of 2mm. A certain study concluded: ranging from 1.7 to 2.8 mm.
The epididymis connects the testes with the ductus deferens. Sperm mature and are stored in the epididymis before moving into the ductus deferens for ejaculation.
The vas deferens (ductus deferens) begins at the epididymis and ends at the ejaculatory duct.
Vas deferens
Transitional Epithelium; it is continuous with that of the kidney pelvis superiorly and the bladder medially. Transistional epithelium is also able to stretch and later recoil when there is room to. (Marieb & Hoehn, Human Anatomy & Physiology, 8th edition, pg. 986)
The ejaculatory duct is formed by the union of the ductus deferens and the seminal vesicle. Specifically, the ductus deferens, which transports sperm from the testes, merges with the duct of the seminal vesicle, which adds seminal fluid to the sperm. This combination occurs as they pass through the prostate gland, where the ejaculatory duct then opens into the prostatic urethra.
There is no ampulla of ductus deferens in pigs
It propels sperm into the urethra during ejaculation. "Ductus Deferens" is also called as "Vas Deferens"
Vas deferens
The epididymis connects the testes with the ductus deferens. Sperm mature and are stored in the epididymis before moving into the ductus deferens for ejaculation.
The ductus deferens is part of the vas deferens and connects the epididymis and ejaculatory ducts.
The vas deferens (ductus deferens) begins at the epididymis and ends at the ejaculatory duct.
The tube is called the spermatic cord, which contains the vas deferens and blood vessels that supply the testes.

Sperm cells move along the ductus deferens through a combination of flagellar movement and muscular contractions of the ductus deferens itself. This coordinated movement propels the sperm towards their destination for ejaculation.
The vas deferens (plural: vasa deferentia), also called ductus deferens, (Latin: "carrying-away vessel"; plural: ductus deferentes), is part of the male anatomy of many vertebrates ; they transport sperm from the epididymis in anticipation of ejaculation.
