(Cowper’s Gland)

4. Male Reproductive System
Epididymis:
Two tightly coiled tubes that rest on top of the testes
Sperm move and mature
Testes or testicles:
Two small glands that produce sperm
They produce male hormone testosterone
They hang outside the body in the scrotum
Scrotum:
External sac of skin that hold testes
Protects testes
Regulates Temperature

5. Male Reproductive System
Foreskin:
A retractable double-layered fold of skin and mucous membrane that covers the glans penis.
Penis:
Spongy tissue
Means for sperm and urine to exit the body
Male external organ
Urethra:
Tube that carries semen and urine through the penis
Bladder:
The organ that collects urine excreted by the Kidneys prior to disposal by urination

6. Male Reproductive System
Vas Deferens:
Two long narrow tubes leading out of the epididymis
Carry sperm to the urethra
Seminal vesicles:
Two small organs about the size of a finger located behind the bladder
Produce nourishing fluid to give sperm energy to move
Prostate Gland:
The size and shape of a chestnut
Secretes fluid to help move sperm
Vas deferens tubes join urethra at prostate gland
Cowper’s gland:
Pea sized glands that connects to the urethra via a tiny duct
Secrete thick, clear mucus prior to ejaculation

Male disorders

8. Male disorders- Circumcision: Removal of the foreskin
Generally removed as an infant
Undescended Testes:
If the Testes fail to descend from the abdomen by the 1st year, hormone medication and/or surgery
Inguinal hernia:
Intestine may push through into the scrotum
Surgery
Testicular Cancer:
A cancer of the Testes that can affect males ages 15-35
Can be treated if found early, may be detected during a self examination
Symptoms: painful urination, blood in semen, general discomfort, enlarged testes, lumps
Prostate Cancer:
This is most common in men 65 years of age

9. Interesting Facts About the Male DID YOU KNOW……………
200 million to 600 million sperm cells may be deposited in the vagina by a single ejaculation.
Of those 200 – 600 million only a few hundred ever reach the egg.
If the sperm does not meet the egg they are either killed by acid, deformed, or they don’t complete the journey.
The male testes produce millions of sperm daily.
Sperm account for 1/10 of the volume of semen.
The journey to the fallopian tube for the sperm cells takes less than an hour following sexual intercourse.

10. More interesting Facts about the male…
Although many sperm cells may reach the egg, in most cases only one will actually fertilize it.
The female egg may survive for only twelve to twenty-four hours following ovulation.
Sperm may live up to seventy-two hours (three days) within the female reproductive tract.
Ejaculation: muscle contractions that push semen through the urethra and out the penis.
Nocturnal emissions (Orgasm): normal ejaculation of semen during sleep.
There is no average size penis when it is soft – most adult erections are the same size: 5 ½ - 6 inches long.
