Sperms produced in seminoferous tubules travel through six meters long single epidydimis. Fallowed by through vas differns in spermatic cord. (Here the tube is ligated in vasectomy.) and enters through external inguinal ring and then internal inguinal ring to the neck of urinary bladder and stored in ampula. During ejaculation they are expelled at very high speed through urethra.

The Wolffian duct system develops into the male reproductive system, including the epididymis, vas deferens, and seminal vesicles. In males, the Müllerian duct system regresses due to the presence of anti-Müllerian hormone.
In the male reproductive system, the urethra and vas deferens join to form the ejaculatory duct, which facilitates the passage of both urine and semen. This structure exits as a single duct through the penis during ejaculation.
Seminal vesicle and prostate glands
The association that the vas deferens carries sperm from the testes to the urethra in the male reproductive system is incorrect. The vas deferens carries sperm from the epididymis to the ejaculatory duct.
The three internal structures of the male reproductive system are the testes, epididymis, and vas deferens. The testes produce sperm and testosterone, while the epididymis stores and maturation of sperm. The vas deferens is a duct that transports sperm from the epididymis to the urethra during ejaculation.
The essential organs of the male reproductive system are the testes, responsible for producing sperm and testosterone; the epididymis, where sperm mature and are stored; the vas deferens, which transport mature sperm to the ejaculatory duct; and the accessory glands (prostate, seminal vesicles, and bulbourethral glands), which produce seminal fluid to nourish and transport sperm.
