Sperm release pathway. Overview. The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. The testes are composed of coiled structures called seminiferous tubules, which are the sites of sperm production.
Vas Deferens - definition, what is and function. What is Vas Deferens and Function of Vas Deferens. A narrow tube that carries SPERM from the epididymis to the ejaculatory duct during ORGASM and EJACULATION. One vas deferens, also called a ductus deferens, arises from each testicle. The smooth-MUSCLE walls of the vas deferens contract and relax in wavelike movements to propel sperm from the testicle to mix with seminal fluid, which then carries the fluid (SEMEN) from the PENIS during ejaculation.
