  4. Testes • Produce Testosterone and Sperm • Outside the body in a sac of skin called the scrotum • Scrotum protects the sperm by maintaining proper temperature

  5. Epididymis • Storage for sperm as they mature

  6. Vas Deferens • Tube that goes from the epididymis to the urethra

  7. Urethra • Tube that goes from the bladder and passes through the penis to the outside of the body. • Carries urine and semen – not at the same time • Valve at the base of the bladder prevents mixing of fluids.

  8. Seminal Vesicles – Cowper’s Gland – Prostate Gland • Glands which produce fluid to mix with sperm • The liquid is then called semen

  9. Ejaculation • Muscles at the base of the bladder, in the prostate and seminal vesicles contract forcing semen through the vas deferens and urethra

  10. Disorders of the Male Reproductive System

  11. Inguinal Hernia • Occurs when part of the intestine pushes into the scrotum • Surgery is usually necessary

  12. Enlarged Prostate • Common in men after middle age • Causes pain and discomfort • Makes urination painful or difficult • Surgery is required

  13. Prostate Cancer • Most common form of cancer among men • Prognosis is good if caught early

  14. Prostate Cancer

  15. Testicular Cancer • Usual age of occurrence is 14-40 • Hard lumps, enlarged testicle, or unusual thickening of the tissue. Lumps are usually painless.
