8. 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

9. meatus – outside opening of the 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

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

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

12. 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

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

14. 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

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

19. 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.

20. Problems of the Male Reproductive System
Injury to the testes
Testicular cancer
Hernia
Sexually transmitted diseases (STDs)
Injury to the testes:
Wearing appropriate protective gear during sports is one way to avoid injuring the testes.
Testicular cancer:
Testicular cancer is one of the most common cancers for males 14 to 34.
Testicular cancer can spread to other parts of the body.
It testicular cancer is detected and treated early, the person has an excellent chance of recovering.
Hernia:
The most common type of hernia, inguinal hernia, occurs when the intestine pushes into the scrotum.
Hernias are mainly caused by incorrect lifting.
A hernia appears as a lump or swelling in the groin or lower abdomen.
Hernias are corrected by surgery.
Sexually transmitted diseases (STDs)
STDs are spread through sexual contact.
Some STDs can cause sterility if left untreated. This means the person cannot produce offspring.
hernia When an internal organ pushes against or through a surrounding cavity wall

The Male Reproductive System

22. 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.

23. 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

24. 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

25. 4. Name one disorder of the male reproductive system
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.

26. 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

27. 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
