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.
Ductus deferens, also called vas deferens , thick-walled tube in the male reproductive system that transports sperm cells from the epididymis, where the sperm are stored prior to ejaculation. Each ductus deferens ends in an enlarged portion, an ampulla, which acts as a reservoir.
