Male Reproductive Systems

Urinary Bladder A muscular organ that acts as a reservoir for urine.
Seminal Vesicle Glands about 2 in. long that attach to the vas deferens near the base of the bladder. They produce fluid that mixes with the sperm to make them more mobile and to provide nourishment.
Testes The male sex glands. They manufacture the male hormone testosterone and produce sperm.
Scrotum The sac that hangs outside the male body and holds the testes. Keeps the testes at the right temp (just under 98.6 degrees) so the testes can produce sperm.
Epididymis The highly coiled structure located on the back side of each testis. Stores newly produced sperm.
Penis The penis is a tubelike organ that functions in sexual reproduction, sexual pleasure, and elimination of liquid body waste.
Vas Deferens The vas deferens are a long tube which connects the epididymis to the urethra.
Prostate Gland The prostate gland lies just below the bladder and surrounds the urethra. It secretes a milky, alkaline fluid that mixes with the sperm and makes up the major portion of semen.
Cowper's Gland Two pea sized glands just below the prostate which opens into the urethra. They secrete a clear, sticky fluid that is thought to cleanse the urethra of acid from urine allowing safe passage for sperm.
Urethra A tubelike organ that travels through the penis. It serves as a passageway for semen and urine. When semen is preparing to leave the body, muscles contract and close off the bladder, therefore no urine will be released during ejaculation.
