The male reproductive system consists of internal and internal structures. The internal male ganglia (also known as accessory organs) consists of the seminal vesicles, the prostrate, the urethra, the bulbourethral glands and the vas deferens.

𝐕𝐚𝐬 𝐝𝐞𝐟𝐞𝐫𝐞𝐧𝐬 (also Ductus Deferens) is a long tube made from fibers and muscle tissue. It travels from the epididymis to the pelvic cavity. Through the ejaculatory ducts, the vas deferens is connected to the urethra.

The 𝐕𝐚𝐬 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. This inner layer is comprised of longitudinal folds, which allows the vas (ductus) deferens to expand during ejaculation.

The stereocilia are apical cell modifications that function for absorption, this absorption creates a fluid current that supports the transport of spermatozoa.
