1. In this lesson, you will learn to  identify the parts of the male reproductive system.  describe the functioning of the male reproductive system.  identify problems of the male reproductive system.  recognize the importance of early detection in the treatment of conditions of the male reproductive system.  describe ways to keep your reproductive system healthy. Unlike other body systems, the reproductive system is different for males and females

2. Reproductive System The body system containing the organs that make possible the production of offspring

3. Parts of the Male Reproductive Testes ….. Testicles Scrotum Epididymis Vas deferens Urethra Seminal vesicles Prostate gland Cowper’s gland Penis

4. Penis - male organ for sexual intercourse, reproduction and urination 2 parts of penis glans : the head of the penis shaft : from the ridge of the glans to the scrotum foreskin: covers the glans at birth circumcision: removal of foreskin 1. hygienic reasons 2. religious reasons 2 states of the penis flaccid: soft and limp erect: hard and enlarges – erection blood vessels become filled with blood

5. urethra the tube that carries semen (sperm & fluids) and urine out of the body, but not at the same time a passageway for semen and urine meatus – outside opening of the urethra

6. scrotum A sac of skin that contains the testes just beneath the penis and regulates temperature for the sperm to reproduce testes – testicles two oval shaped glands that produce sperm and testosterone epididymis network of tubes where sperm mature and are stored temporarily Located behind each testicle

7. vas deferens tubes that go from the epididymis to the urethra a passageway for sperm

8. semen – (SEE-muhn) the mixture of sperm and fluids seminal vesicle two glands on either side of the bladder that secrete a fluid, (seminal fluid), that combines with sperm in the vas deferens seminal fluid provides nourishment to sperm prostate gland gland near the bottom of the bladder; it forms a milky fluid that combines with sperm and seminal fluid in the vas deferens keeps sperm alive Cowper’s gland a pair of small glands that secrete a mucous substance that adds to semen to neutralize the urethra

9. tail head neck sperm male reproductive cell 3 parts: head, neck, tail head contains DNA chromosomes neck supplies energy and nutrients tail provides mobility

10. Path of the sperm produced in the testes stored in the epididymis travels through the vas deferens where other fluids are added to create semen seminal vesicle secretes seminal fluid prostate gland secretes a milky fluid Cowper’s gland secretes a mucous substance semen travels through urethra –urethra is a tube that is inside the penis meatus – outside opening of urethra semen is ejaculated out of the top of the penis

11. ejaculation: the action that forces semen through the urethra & out of the body

13. Healthy Habits for male Practice abstinence from sex - this can prevent infections with HIV and other STDs Bathe or shower daily - keeping your reproductive organs clean is important because it will cut down possible infection and reduce the risk of cancer of the penis …..smegma Avoid wearing tight clothing Wear protective clothing for sports - Athletic support is necessary for the penis and testes and a cup can prevent injuries to those organs additionally. Perform TSE - Testicular self-examinations are a way to check your own testicles for lumps or tenderness. Have regular medical checkups - a physician can examine a male and answer any question he has. Get medical attention for signs of infection - lumps, sores, rashes, or a discharge from the penis require medical attention. These can be symptoms of STDs.

14. Problems of the Male Reproductive System Injury to the testesTesticular cancer Hernia Sexually transmitted diseases (STDs) hernia When an internal organ pushes against or through a surrounding cavity wall

19. 1. Define the terms scrotum and testes and explain how these parts of the male reproductive system functions. The scrotum is a loose sac of skin that hangs outside the body. It holds the testes. The testes are the male sex glands, they manufacture testosterone and produce sperm. To produce sperm, the temperature of the testes must be a few degrees lower than normal body temperature. The scrotum keeps the testes at the right temperature by holding the testes away from or close to the body as needed.

20. 2. List the external and internal male reproductive organs. External organs –Scrotum –Testes –penis Internal organs –Vas deferens –Seminal vesicles –Prostate glands –Cowper’s glands –Urethra

21. 3. Analyze the relationship between good personal hygiene, health promotion, and disease prevention. Describe two ways to care for the male reproductive system. Care for the male reproductive system includes washing the external organs and monthly testicular self-examinations. Taking care of the reproductive systems helps prevent problems. Early detection of problems is key

22. 4. Name one disorder of the male reproductive system. Explain why it is important to look for warning signs and seek early detection to prevent disease. Possible answer …… Cancer of the testes can be detected through monthly testicular self-examination.

23. 5. Describe the route of sperm from testes to the penis. Sperm is produced in the testes Move into epididymis where they mature Travel through vas deferens –seminal vesicles –prostate glands –Cowper’s glands Into the urethra Through the tip of the penis …. meatus

24. 6. How might the male reproductive system be affected if the reproductive glands did not function properly? Possible answers: If seminal vesicles did not function properly – sperm wouldn’t get nourishment and be mobile If the prostate gland did not function properly – acids in the urethra and those encountered during intercourse in the vagina would destroy the sperm If the Cowper’s glands did not function properly – the acidity of any urine that might be in urethra would destroy sperm
