The
ductus deferens is a tortuous tubule, which originates in the epididymis on the dorsal aspect of the testis, runs alongside the ureter, across the dorsal aspect of the coelom, and penetrates the dorsal wall of the urodeum, where it forms the short papilla of the
ductus deferens.
The juveniles exhibited epididymis and testes little differentiated from the epigonal organ and ampullae of the
ductus deferens with a diameter of less than 0.5 cm.
As noted previously the scrotum encases the testes, which are suspended from the abdominal cavity via the spermatic cord, which is connective tissue that supports the
ductus deferens, lymphatics, nerves, and blood vessels that carry blood to and from the testes.
All of the patients carrying the 5T allele had been diagnosed with azoospermia; one of them had
ductus deferens agenesis.
Length and calcification stage of claspers, width of epididymides, and the presence of seminal fluid in the ampullae of the
ductus deferens were recorded from males.

There are also reports of works on domestic fowl (Gallus domesticus) testis albunigeous tunic (Aire, 1979), seminiferous tubules (Marvan), testicular net (Aire, 1982 and Tingari),
ductus deferens and epididymis (Marvan; Tingari; Tingari & Lake, 1972 and Aire, 1980), cloaca (Marvan) and interstitial tissue (Amer & Shahin and Rothwell, 1975).
Medially it was related to the left ureter and
ductus deferens. Throughout its course except near its origin it was related to the obturator fascia and obturator internus muscle laterally.
