The ductus deferens extends from the epididymis to the ejaculatory ducts. The epithelium of this tube displays a pseudostratified columnar epithelium and is surrounded by a prominent muscular layer. This layer contains inner and outer longitudinal muscle and middle circular muscle. An adventitia of connective tissue surrounds the muscularis layer The vas (ductus) deferens is a muscular tube that is located within the spermatic cord and is a major component of the male reproductive system. It is a continuation of the epididymis and is involved in transporting spermatozoa from the epididymis to the ejaculatory ducts. The vas (ductus) deferens may also be referred to as the ductus deferens
Vertical section of the testis, to show the arrangement of the ducts. (Labeled as vasa efferentia as top center.) The efferent ducts (or efferent ductules or ductuli efferentes or ductus efferentes or vasa efferentia) connect the rete testis with the initial section of the epididymis Thus, we hypothesize that there may be variations in the anatomy, histology, and the role of the vas deferens in general, and the ampulla in particular, of the squamate reptiles. In this study, the ductus deferens of the small fan-throated lizard Sitana ponticeriana (Fam: Agamidae) was subjected to light and transmission electron microscopic analysis Testis histology labeled diagram is so important to understand the all structures of testis.

Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia Our histological study revealed that the ductus deferens was covered with pseudostratified epithelium with mean height of 22 µm.

All specimens were processed following standard histological procedures. Five to seven micrometers thick sections were stained routinely with hematoxylin and eosin and with a special stain (Masson's trichrome t Ampulla of the Ductus Deferens. The ductus deferens (or vas deferens) is a muscular tube connecting the epididymis with the urethra in the prostate. At the level of the seminal vesicle, the ductus deferens expands to form the ampulla. Ampulla - resembles the rest of the ductus deferens except that its surface has more longitudinal folds
Testis, in animals, the organ that produces sperm, the male reproductive cell, and androgens, the male hormones. In humans the testes occur as a pair of oval-shaped organs. They are contained within the scrotal sac, which is located directly behind the penis and in front of the anus. In humans eac The distribution of elastic fibres in the human ductus deferens from birth to senility was studied by light and electron microscopy. Elastic fibres are lacking in the ductus deferens in infants and children. In the adult ductus deferens, they form two layers in the lamina propria: (1) an inner layer Histology of Birds.

Histology of Ductus deferens The ductus epididymidis, after a sharp bend at the end of the tail, gradually straightens and acquires the histologic characteristics of the ductus deferens. In stallions and ruminants, the ductus deferens unites with the excretory duct of the vesicular gland to form a short ejaculatory duct, which opens at the colliculus seminalis into the urethra

Prostate gland & prostate urethra Prostate gland Prostetic urethra Psuedostratified epithelium Glandular acini vary in size Lumina of acini normally wide and irregular Protrusion of epithelium-covered connective tissue folds Proteinaceous secretions sometimes prostatic concretions The cross section of Male Reproductive System highlights the structures like Ductus deferens, Prostate gland, Scrotum, Corpus cavernosum, and penis. The process of spermatogenesis involves various phases viz Golgi and acrosomal phase which is followed by early and mid-maturation phase The glands of the ductus deferens have long been recognized as a part of the male accessory sex glands in the rat (Greene 1949). The name suggests the close association with the vas deferens. These glands probably arose from an evagination of ampullary tissue of the vas deferens during embryogenesis The vas deferens has been described as a heavily muscular tube in humans as reported by [28, 29] and possesses narrow and irregular lumen. The thickness of the wall, luminal diameter, and longitudinal folds in the lumen of the vas deferens in this study were similar to the reports of in rat and humans

Danko: Vasculature of testis, epididymis and ductus deferens of Rabbit. The Arteries. Acta Vet. Brno 2001, 70: 3-7. The vasculature of the testis, epididymis and ductus deferens. The tail of the epididymis continues craniodorsally up into the spermatic cord as the ductus deferens (vas deferens). The ductus deferens enters the abdominal cavity through the inguinal canal, crosses ventral to the ureter at the lateral ligament of the bladder, and penetrates the dorsal prostate to insert into the prostatic urethra (Figures 111-1 and 111-2). 2 He is currently a Senior Honorary Research Fellow in the School of Human Sciences at UWA (School was renamed in 2017), where he still continues to teach Histology.
