  2. Male Reproductive System • Put the following labels on your diagram. Do it in pencil so you can fix any mistakes you may make.

  4. Testes • Testes are responsible for making testosterone, the primary male sex hormone. • Also create sperm within coiled masses of tubes called seminiferous tubules.

  5. Seminiferous Tubules

  6. Testes • The epididymisis a long, coiled tube that rests on the backside of each testicle. • It transports and stores sperm cells that are produced in the testes. • It also bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization.

  7. Testes • The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity. • The vas deferens transports mature sperm to the urethra.

  8. Urethra • The function of the urethra is two fold in males. • It carries urine from the bladder to outside of the body. • Also delivers sperm and semen when the man reaches orgasm.

  9. Penis • The male organ used in sexual intercourse is the penis. • The body (shaft) of the penis is cylindrical in shape and consists of 3 circular shaped chambers. • These chambers are made up of special, sponge-like tissue that fills with blood when the man is sexually aroused.

  10. Functions

  11. Glands • Cowper's Gland is apea-sized gland that produce an alkaline fluid that forms part of the semen. • The fluid neutralizes the acidic environment of the urethra, thereby protecting the sperm.

  12. Glands • The prostate gland stores and produces seminal fluid. Seminal fluid is a milky liquid that nourishes sperm. • The urethra runs directly through the prostate. • The prostate contains some smooth muscles that help expel semen during ejaculation.

  13. Glands • The seminal vesicles secretes about 70% the fluid that ultimately becomes semen. • The thick secretions contain proteins, enzymes, fructose, vitamin C and other compounds. • Also contains smooth muscular walls that expel semen during ejaculation.

  14. Sperm • Each sperm looks like a tadpole, with a head (containing nucleus), a body and a tail which is used for swimming.

  15. Sperm • Draw a sperm in your notes and label the head, body, tail and acrosome.
