Classwork/Homework Male Reproductive System

1
The Male Reproductive System
Unlike other body systems, the reproductive
system is different for males and females

• 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.

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
• Cowpers 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
testes testicles 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
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
Cowpers gland a pair of small glands that
secrete a mucous substance that adds to semen to
neutralize the urethra
9
sperm male reproductive cell 3 parts head,
neck, tail head contains DNA chromosomes neck
supplies energy and nutrients tail provides
mobility

• 
  head
• neck

tail
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
• Cowpers 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

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.

Problems of the Male Reproductive System
Injury to the testes
Testicular cancer
Hernia
Sexually transmitteddiseases (STDs)
hernia When an internal organ pushes against or
through a surrounding cavity wall

• The Male Reproductive System

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
• Cowpers 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
• Cowpers 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 wouldnt 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 Cowpers glands did not function properly
  the acidity of any urine that might be in
  urethra would destroy sperm
