Vas deferens - the duct that transports sperm from the epididymis to the ampulla (a dilated terminal part of the duct), ready for ejaculation. Sperm and the alkaline, fructose-rich fluid from the seminal vesicle move from the ejaculatory duct into the prostatic urethra, where they are mixed with a slightly acidic mucoid fluid from the prostate.

Cells a. Leydig cells (interstitial cells) - produce testosterone 1) found between seminiferous tubules b. The structures of the male reproductive system include the testes, the epididymides, the penis, and the ducts and glands that produce and carry semen. The ductus deferens is a thick, muscular tube that is bundled together inside the scrotum with connective tissue, blood vessels, and nerves into a structure called the spermatic cord (see . 3. When ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent duct. The ampulla of the ductus deferens merges with the duct of the seminal vesicle to form the ejaculatory duct. The epididymis is a narrow, tightly-coiled tube connecting rear of the testicles to the deferent duct (ductus deferens or vas deferens). The internal pudendal artery constricts and reduces blood flow to the penis. Sperm exit the scrotum through the vas deferens. In humans, each tube is about 30 centimeters (1 ft) long, 3 to 5 mm (0.118 to 0.197 inches) in .

The epididymis is a long, coiled tube that transports sperm from the testes to the vas deferens. Sperm exit the scrotum through the ductus deferens, which is bundled in the spermatic cord. Sperm are produced in the testicles and develop to maturity while traveling from the seminiferous tubules through the epididymis into the vas deferens. Bulbo-urethral gland: . The blood-testis barrier A. feeds sustentacular cells. This is a gland that produces fluid that is a major component of semen. If sperm aren't ejaculated, they're eventually reabsorbed by the epididymis. The epididymis sits directly on top of each testis. Sperm move through each Vas Deferens and into the Urethra. The sperm ducts (or ductus deferens) are a complex set of structures of various kinds whose main functions are two fold: to allow the transit of sperm from the testicles to the outside of the body and allow the maturation of the sperm cells themselves. 5. The epididymis consists of three parts, the caput (head), corpus (body), and cauda (tail.) The diagram shows the locations and relationships of the testes, epididymis, glands, and the ductus deferens running from the scrotum to the urethra. Sperm ducts.

Contractions of the _____ muscles result in ejaculation. 3) Sperm are moved along the ductus deferens (vas deferens) by A) hydrostatic force. Semen is expelled from the urethra. C) the corpus luteum is formed from the ruptured follicle after ovulation. During ejaculation, sperm exit the tail of the epididymis and are pushed by smooth muscle contraction to the ductus deferens (also called the vas deferens). In this article we aim to cover the embryology, anatomy, histology and functions of the epididymis. These paired muscular tubes are also called the ductus deferens. Sperm move the the Vas Deferens to begin traveling through the male body ("The Sperm Highway").
