  1. Without it Life Does Not Go On The Male Reproductive System

  2. BIG IDEA • THE Male Reproductive system is a series of organ that function to produce children.

  3. Objectives • Students will be able to explain: • The main function of the male reproductive system. • Name parts of the system. • Name the male sex hormone. • Explain how to care for the male reproductive system after viewing a PowerPoint presentation.

  4. How Male Reproductive Work • Two main functions • To produce and store sperm. • Transfer sperm into the female’s body during sexual intercourse.

  5. Male Maturity • Ages 12-15 male reaches maturity • Pituitary gland stimulates the production of: • Testosterone which is the: • Male sex hormone • Initiates physical changes such as: • Broadening of shoulders • Development of muscles • Facial hairs and other body hair • Deepening of voice • Controls production of sperm

  6. External Reproductive Organs • Testes or testicles • Two small glands that secrete testosterone • Produce sperm and are located in the: • Scrotum • External skin sac • Penis • Tube-shaped organ • Extends from the trunk of the body above the knees • Composed of spongy tissue • Contains many blood vessels • Semen • A thick fluid containing sperm and other secretions from the male reproductive system • Fertilization • The joining of male sperm cell and a female egg cell

  7. More About the Male Organ • Foreskin • A thin, loose skin at the tip of the penis • Circumcision • Surgical removal of foreskin of the penis • Cultural reasons • Religious reasons • 98.6 degrees • Nocturnal

  8. Male Sperm Close-up

  9. Internal Reproductive Organs • Vas deferens • Tubes that extend from each epididymis to the urethra • The Urethra Passageway through which both semen and urine leave the body • The seminal vesicles Sperm travel through vas deferens—combine w/fluid produced by seminal vesicles—fluid contains nutrients to nourish sperm—making them more mobile • The prostrateand Cowper’s glands Fluids from prostrate and Cowper’s gland—combine w/sperm-containing fluid to form sperm • Epididymis Tubes in each testes join the epididmyis Large coil tube Sperm mature Stored • Testis Divided into hundreds of tiny tubules Sperm is formed here

  10. Male Reproductive System

  11. Maintaining Reproductive Health • Bathe regularly Shower/bathe daily Cleanse penis/scrotum Uncircumcised—wash under foreskin • Wear protective equipment Protective cup/supporter during physical activities to shield external reproductive organs • Practice abstinence • Abstain from sexual activity until marriage • Prevents contracting sexually transmitted diseases (STDs/STIs) • Perform regular self-examinations Check scrotum/testicles monthly for signs of cancer Report changes to physician Early detection usually leads to successful treatment • Get regular check-ups Regular check-ups every 12-18 months If abnormal—consult a urologist—specialist who cares for the male reproductive system

  12. Male Reproductive System Problems • Inguinal hernia Part of intestines pushes through a tear in the abdominal wall May be caused by straining abdominal muscles Lifting heavy objects • Symptoms Lump in groin near the thigh Pain in groin Blockage of intestine Surgery can repair

  13. Male Reproductive System Problemscontinued • Sterility Inability to reproduce Too few sperm/poor sperm quality Exposure to x-rays/other radiation Hormonal imbalances Mumps contracted during adulthood Certain medications/drugs such as anabolic (synthetics) steroids STDs/STIs can cause sterility • Testicular cancer Effects males at any age, usually 14-40 years of age Early detection

  14. Male Reproductive System Problems continued • Testicular cancer Effects males at any age, usually 14-40 years of age Early detection • Treatable through Surgery Radiation Chemotherapy • Prostate problems/prostate cancer Become enlarged as a result of Infection Tumor Age Early detection Increase survival rates

  15. How to Do a Testicular Self-Exam (TSE)
