Penis:

The male genital organ carrying the duct for the transfer of sperm during copulation; consists largely of erectile tissue and serves also for the elimination of urine.

Scrotum

The sac that holds testes away from the body to maintain lower temperature during sperm production.

Seminiferous tubules:

Reside in testes and produce sperm.

Testes

Primary reproductive organ.

Vas deferens:

Thick-walled tube in the male reproductive system that transports sperm cells from the epididymis, where the sperm are stored prior to ejaculation.
