describe in brief the role of (i) testis (ii) seminal vesicle,(iii)vas deferens,(iv)ureter and (v)prostate gland in human male reproductive system

TESTIS: Testis helps in the production of male gamete i.e. sperms and is responsible for the secretion of androgen, i.e. testosterone.
SEMINAL VESICLES: Helps in Production and nourishment of sperms. Seminal Vesicle also secretes a  fluid which makes semen and creates the medium for easy movement of sperms
PROSTATE GLAND- The prostate gland secretes an alkaline fluid that nourishes and protects sperm and also helps in sperm motility.
VAS DEFERENS: The vas deferens is a pair of tube comprised of smooth muscle, that passes upward alongside the testicles, through the prostate, and open into the urethra and is associated with making an environment rich for transport and nutrition of sperms. The vas deferens transports mature sperm to the urethra for ejaculation. 
URETER: Ureter is the duct in pairs which transport urine from respective kidneys to the urinary bladder, where urine is stored until it is passed through the urethra.

Vas deferens — The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.

Prostate gland — The prostate gland is a walnut-sized structure that is located below the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also help to nourish the sperm. The urethra, which carries the ejaculate to be expelled during orgasm, runs through the center of the prostate gland.

Seminal vesicles — The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a source of energy and helps with the sperms motility (ability to move). The fluid of the seminal vesicles makes up most of the volume of a mans ejaculatory fluid, or ejaculate.
