In many species of passerine birds (9) and in the budgerigar, (10) the caudal portion of the ductus deferens forms a paired, convoluted structure that denominates the seminal glomera, (9) located on the lateral lower section of the abdomen.
The wall of the abdominal air sac is penetrated to expose the testis and the ductus deferens located on the ventral aspect of the anterior pole of the kidney.
As noted earlier, this connective tissue supports the ductus deferens, as well as lymphatics, nerves, and blood vessels.
This duct system consists of the efferent ducts, epididymis, and ductus deferens. The urethra is also involved, but this duct is also part of the urinary system and is therefore considered separately.
Individuals with relatively short, flexible claspers, and filiform ampullae of the ductus deferens
were considered juveniles.

Fine structure of the lining epithelium of the ductus deferens in gerbil, a segmental study.
Ductus deferens The duct running from the epididymis of the testis to the pelvic urethra.
Epididymis The coiled tubule attached to the testis connecting the efferent ducts with the ductus deferens. It consists of the head (caput), body (corpus), and tail (cauda).
(1983) carried out analysis of the anatomical features of male pigeon (Columbia livia, L.) testis, epididymis, ductus deferens and copulator organ.
(1976) described the ductus sucession from the seminiferous tubules to the ductus deferens papilla, as well the microscopy of the epididymal region and ductus deferens in turkey (Meleagris gallopavo).
