The parts of human male reproductive system are a pair of testes,vas efferentia, epididymis, vasa deferentia,
ejaculatory ducts, seminal vesicles, Cowper's glands, urethra, prostate gland and penis.

Testis:These are oval organs located in the scrotum and produces testosterone, and the sperm. Within the
testes are coiled masses of tubes called seminiferous tubules. These tubes are responsible for producing
sperm cells.

Vasa efferentia: They are 10-20 fine tubules which connect rete testes with an epididymis.

Epididymis: They are a pair of ducts arising from each testis which is formed by the union of vasa efferentia
.It is a long, narrow highly coiled compacted tubule which lies on upper, lower back side of testes.

Vas Deferentia: They are a pair of uncoiled straight tubes. The wall is thick and muscular. It conducts
sperms. They can also store and nourish the sperm during the passage

Ejaculatory Ducts: These are two short ducts one on each side, by the union of vas deferens and the duct of
seminal vesicle.

Urethra: The male urethra provides a common pathway for the flow of urine and the secretion of the male
reproductive organs called semen

Penis:  The male external genitalia are called penis. This external muscular organ is used in mating. Both
urine and semen is passed out of the body through the penis.

Accessory glands produce the secretion for viability and motility of the sperms.

Seminal vesicles are long pouches with muscular wall located behind the neck of the urinary bladder. Seminal
vesicle secrete the seminal plasma Prostate gland produces a milky alkaline fluid which activates sperm motility.

Cowper's glands secretion is rich in mucus for lubricating the urinogenital tract
