Pathway of spermPathway of spermThe testes are where sperm are manufactured in The testes are where sperm are manufactured in the scrotum. The epididymis is structure topping the scrotum. The epididymis is structure topping the testis, and it receives immature sperm from the testis, and it receives immature sperm from the testis and stores it several days. When the testis and stores it several days. When ejaculation occurs, sperm is forcefully expelled ejaculation occurs, sperm is forcefully expelled from the tail of the epididymis into the deferent from the tail of the epididymis into the deferent duct. Sperm then travels through the deferent duct. Sperm then travels through the deferent duct through up the spermatic cord into the duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and duct, which passes through the prostate and empties into the urethra.empties into the urethra.
