Path of sperm from testes
Sperm cells pass through a series of ducts to reach the outside of the body. After they leave the testes, the sperm passes through the epididymis , ductus deferens , ejaculatory duct , and urethra. Sperm leave the testes through a series of efferent ducts that enter the epididymis. Each epididymis is a long about 6 meters tube that is tightly coiled to form a comma-shaped organ located along the superior and posterior margins of the testes.

Pathway of sperm
Processes in the male genital tract
The testes are where sperm is manufactured. The epididymis is a long coiled structure topping the testis, and it receives immature sperm from the testis and stores them as they mature. When ejaculation occurs, sperm are forcefully expelled from the tail of the epididymis into the vas deferens. Sperm then travel through the vas deferens through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra. When ejaculation occurs, rhythmic muscle movements propel the sperm forward.

Quiz The supplying of the spermatozoa occurs in the male genital tract. Figure 21 provides an overview of the path the spermatozoa travel during an ejaculation. The ejaculation path of the sperm is formed by the two vas deferens 3 , both ejaculatory ducts 6 , and the urethra The ejaculatory duct refers to the canal that goes through the prostate into the urethra.
Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomes—one half the number in body cells. At fertilization, the chromosomes in one male gamete, called a sperm or spermatozoon , combine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system is to produce sperm and transfer them to the female reproductive tract.
