3. The Male Reproductive System

4. Objectives State (What is) the role of the male reproductive system
Describe (What is) the function of each of the organs of the male reproductive system
Summarize (What are) the problems that can occur with the male reproductive system
List (What are) the things a male can do to keep his reproductive system healthy

5. Key Vocabulary Words & Definitions
Sperm - the sex cell produced by the testes & needed to fertilize an egg
Egg (Ovum) - the sex cell produced by the ovaries & can be fertilized by sperm
Testes (Testicle) - male reproductive organ that makes sperm & testosterone

6. Key Vocabulary Words & Definitions
Fertilization -the process by which a sperm & an egg w/their genetic material join to create a new human life
Reproduction – the process of producing a new human being

7. Key Vocabulary Words & Definitions
Semen - a fluid made up of sperm & other secretions from the male reproductive organs
Ejaculation – the release of semen through the urethra

8. The Penis The Male Reproductive Organ That:
Removes urine from the body
Delivers sperm to the female reproductive organs
Is erect during ejaculation
Can ejaculate while sleeping called “wet dreams”

9. Key Vocabulary Words & Definitions
Glans – the tip (head) of the penis; made up of nerve endings that make it extremely sensitive
Shaft – the rest of the penis
Circumcision – removal of the foreskin; often done for religious/cultural reasons

10. What Is Puberty & What Happens To The Body?
Begins between years old
Hair growth (face, chest, arm pit, pubic)
Shoulders broaden
Voice deepens
Penis grows… Sometimes
Testicles produce sperm and testosterone
The sex drive begins…

11. What Does The Male Reproductive System Do?
The male reproductive system works to produce sperm and deliver it to the female reproductive system.

12. The Path Of The Sperm

14. How the Male Reproductive System Works The male reproductive system is made up of internal and external organs.
Testes (testicles)
Makes sperm (hundred million sperm/day)
Makes testosterone (major sex hormone of male)
Rests in the scrotum (keeps the sperm cooler than normal body temperature)

15. The Path Of The Sperm Epididymis
Sperm travels from testes to the Epididymis where they finish their development;
Sperm stays in the Epididymis for 6-10 days;

16. The Path Of The Sperm Vas Deferens
From the Epididymis, sperm travels through the Vas Deferens waiting to be ejaculated;
Sperm will live for up to 6 weeks before they disintegrate

17. The Path Of The Sperm Seminal Vesicles
Produces a thick secretion that helps sperm move easier
Produced at the beginning of an orgasm as sperm is being released

18. The Path Of The Sperm Prostate Gland
Secrets a thin, milky fluid that protects the sperm from acid in the female reproductive system
Fluid is no longer sperm, now it is semen

19. The Path Of The Sperm The Bulbourethral or Cowper’s Gland & Urethra
Cowper’s Gland - Secrets a clear fluid that protects the sperm from acid in the male urethra
Urethra - The canal through which urine and semen leaves the body.

20. Problems of the Male Reproductive System
What Is It ?
Symptoms
Treatment
Jock Itch
Fungal infection of groin area
Itchy rash in groin
Keeping area cool and dry
Cystitis
Inflammation of the urinary bladder
Burning during urination
Antibiotics prescribed by a doctor
Prostatitis
Bacterial infection of the prostate
Fever, pain in the pelvis
Inguinal hernia
Bulging of the intestines or other structure through a weakness in the abdominal wall
Abnormal bulge in the abdomen, groin, or scrotum
Immediate medical care

21. Problem What Is It ? Symptoms Treatment Testicular Torsion
Twisting of a testes – can happen during physical activities
Elevation of a testes, swelling & tenderness, nausea or vomiting
Immediate medical care; if not, testes may need to be removed
Un-descended Testes
One or both testes not moving from the abdomen to the scrotum during fetal development
One or no testes in the scrotum
Surgery or hormone therapy
Prostate Cancer
50+
Abnormal division of cells in the prostate; may be hereditary
Difficulty, burning, or blood from urinating or defecating – or no symptoms
Surgery, radiation, &/or chemotherapy
Testicular Cancer
15 – 35 yr. olds
Abnormal division of cells in the testes;
may be hereditary
Lump on testes, enlargement of testes, sense of heaviness, or no symptoms

22. 6 Ways To Keep Healthy
Wear appropriate protective gear when playing contact sports.
Avoid wearing tight clothing.
Wash the penis & scrotum every day, & dry yourself carefully after showering.
If you are not circumcised, wash underneath the foreskin.
Perform a monthly testicular self-exam.
Have an annual checkup w/a doctor.

23. Preventing Problems
Watch for any changes or symptoms that might indicate a problem.
If any symptoms or problems are present, see the doctor right away.

24. Preventing Jock Itch A fungal infection in the groin area.
Physically active males in hot & humid locations are more likely to get jock itch.
Can usually prevent jock itch by wearing cotton clothing & by drying themselves thoroughly after a shower.
It is important to avoid wearing damp clothes for too long
Avoid sharing towels or clothes w/others.

25. Preventing Trauma Injuries due to an external force
Injuries can happen playing sports, from car or bicycle accidents, or during “horseplay”.
One way to reduce the risk of traumatic injuries to the testes is to wear protective gear when playing sports.

26. Preventing Hernias
When a piece of the intestine bulges into a weak place in the wall of the abdomen or groin.
Caused by straining to lift or push something heavy.
Can occur when coughing or sneezing.
Doctors check for signs of a hernia by feeling for bulges in the groin while a male coughs.
Avoid strenuous lifting
Use your knees, not your back to when lifting heavy objects.

27. Preventing Infertility
Inability to fertilize an egg
Infertility can be genetic
It can be caused by environmental conditions such as heat & trauma to the testes.

28. Testicular Self-Exam
Each month, perform the self-exam during or after a warm bath or shower
Stand in front of the mirror, and hold the penis out of the way
Examine each testicle separately
Look and feel for any lumps or any change in the size, shape, or consistency of the testicle
Contact your doctor if you detect any troublesome signs

29. Early Detection Of Prostate Cancer
Occurs mainly in older males
Regular exams can detect prostate cancer early.
Treatment is most effective when prostate cancer is detected early
Delaying doctor’s exams &/or treatment can be deadly.
