1. The Male Reproductive System

2. MALE DIAGRAM

3. External Male Organs Scrotum
Loose sac of skin that surrounds the testes
Regulates temperature of testes
Testicles (Male sex glands)
Produce sperm
Epididymis
Tubes located on back of each of the testes
Stores sperm
Penis
Tubelike organ that functions for reproduction, sexual pleasure, and elimination of body waste

4. Internal Male Organs Vas deferens Tube that carries sperm
Seminal Vesicle
Gland that secretes sugary solution that mixes with sperm to aid in mobility
Prostate Gland
Gland that secretes an alkaline solution to sperm to decrease the acidity of the vagina
Cowper’s Glands
2 pea-sized glands that open into urethra
Secrete a lubricating fluid
Urethra
Tube that carries urine or semen

5. 3 Glands that Make Semen
Seminal Vesicles- secretes sugary solution to aid in mobility of sperm
Prostate Gland- secretes alkaline solution to decrease acidity of the uterus
Cowper’s Gland (bulbo-urethral glands)- secretes lubricating fluid

6. 2 TUBES
Urethra- brings urine or semen out of the body through the penis
Vas deferens- tube that carries sperm from the testes

7. Terms Erection- when the penis becomes engorged with blood
Ejaculation- when the semen leaves the penis
Semen-mixture of sperm and other fluids
Sterility-unable to reproduce
Vasectomy- a surgical procedure in which the vas deferens in manipulated

8. Terms (cont) Sperm cells-cells produced in the testes
Epididymis- gland located on top of each testicle that stores sperm

9. Concerns about male body:
Nocturnal Emission (“wet dream”)
Ejaculation that occurs during sleep
Hernia
Weak spot in abdominal wall near scrotum
Sterility
Unable to reproduce
Due to malformed or nonexistent sperm

10. Cancers of the male Testicular Cancer 1% of all cancers in men
Most common in ages 15-34
12% of all cancer deaths
Signs:
Slight enlargement in teste
Lump (small, hard)
Dull ache and heaviness

11. Cancers (cont.) Prostate Cancer
Most common cancer in men after lung cancer
Common in men 50 and older
Signs:
Difficult/frequent urination
Blood in urine
Lingering pain in back, hips, or pelvis

12. Cancer Early detection is best way to prevent or treat cancer
Surgery may be necessary

13. Path of sperm: Testicles Epidiymis Vas Deferens Seminal Vesicle
Prostate Gland
Cowper’s Gland
Urethra
Exits penis
