2. Male Reproductive System
Testis and Epididymis
Testes produce male gametes (spermatozoa) and male sex hormone- testosterone
Found in pouch of skin called a scrotum
Size of small egg
Made up of 250 lobules, each with coiled seminiferous tubules-where sperm develop
They join to form the epididymis where sperm are stored they join at the vas deferns

5. Sac of skin that contains testes
Vas Deferens
Runs from epididymis to ejaculatory duct
Seminal vesicles connect to vas deferens secretion nourish sperm
Ejaculatory duct- connect vas deferens with urethra
Scrotum
Sac of skin that contains testes
Descent of the testes
In embryo, testes formed in the abdomen
During last 3 months, migrate into scrotum
Cryptorchidism- when testes don’t descend
Rx-surgical procedure before puberty
Penis
Contains erectile tissue
End of penis covered by loose fitting skin –foreskin
Foreskin removed during circumcision

6. Prostate gland
Surrounds beginning of urethra
Size and shape of a chestnut
Secretes a fluid that enhances sperm motility
Bulbourethral glands
Located on either side of prostate below prostate
Add alkaline secretion to semen that helps sperm live longer

7. Erection and Ejaculation
Urethra has a dual role-excretion of urine and to expel semen
Erection caused when erectile tissue fills with blood
Ejaculation expels semen
Impotence unable to copulate (hold an erection)
Infertility
When conception does not occur- caused by damage to fallopian tubes, low sperm count, hormone imbalance, other disorders

8. Male Reproductive Disorders
Vasectomy
male sterilization, removal of part of the vas deferens

9. BPH (BENIGN PROSTATIC HYPERTROPHY)
·    Enlarged prostate
·          More than half of men in their sixties and 90% of men in their seventies have some symptoms
·        Prostate enlarges but capsule does not, causing prostate to clamp down on urethra.
           
  This causes the bladder to become irritable, causing urinary frequency
·     Diagnosis by rectal exam, ultrasound, and cystoscopy
Rx – usually prostatectomy – laser surgery, sometimes no Rx
