After sperm are produced, they move into a sperm storage area called the EPIDIDYMIS.
The male reproductive system is composed of the testes, urethra, vas deferens, prostate gland, seminal vesicle, and penis.
The testes contains seminiferous tubules, the sites for sperm reproduction, and epididymis, where immature sperms are stored to mature.
From the epididymis, the mature sperm travels through the vas deferens where it is combined with a liquid secretion from the seminal vesicles. The liquid secretion passes through the prostate gland. The mixture of sperm and liquid secretion are ejected through the urethra and is identified as semen.
