testosterone
the principal male sex hormone. Its chief function is to stimulated the development of the male reproductive organs and secondary sex characteristics such as facial hair,
seminiferous tubules
approximately 900 coiled tubes within the testes in which sprematogenesis occurs
epididymis

vas deferens,
ductus deferens,

duct carrying the sperm from the epididymis to the urethra. The spermatic cord encloses each vas deferens with nerves, lymphatics, arteries, and veins. The urethra also connects with the urinary bladder and carries urine outside the body, A circular muscle constricts during intercourse to prevent urination.
seminal vesicles
two main glands located at the base of the bladder that open into the vas deferens. The glands secrete a think fluid, which forms part of the semen.
prostate gland
encircles the upper end of the urethra. THe prostate gland secretes a fluid that aids in the movement of the sperm and ejaculation.
