PATHOLOGY

Detailed explanation-1: -The epididymis is a narrow, tightly-coiled tube connecting rear of the testicles to the deferent duct (ductus deferens or vas deferens). The epididymis consists of three parts: head, body, and tail. The head of the epididymis is located on superior pole of testis. It stores sperm for maturation.

Detailed explanation-2: -The vas (ductus) deferens consists of an inner epithelial lining with supportive lamina propria. The epithelium lining the vas (ductus) deferens is pseudostratified columnar epithelium and is very similar to the epithelium seen in the epididymis.

Detailed explanation-3: -The ductus deferens, or vas deferens, is a fibromuscular tube that is continuation of the epididymis and is an excretory duct of the testis. Each ductus is 30-45 cm in length and serves to transport sperms cells from the respective epididymis to the ipsilateral ejaculatory duct.

Detailed explanation-4: -The ductus deferens is 5–6 cm in length, and runs in the spermatic cord from the tail of the epididymis to join the urethra as it passes through the prostate gland. As the ductus approaches the prostatic urethra it widens into an ampulla, where the ducts of the seminal vesicles join the ductus.
