Title: Classwork/Homework Male Reproductive System
1The 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.
2Reproductive System
- The body system containing the organs that make
possible the production of offspring
3Parts of the Male Reproductive
- Testes .. Testicles
- Scrotum
- Epididymis
- Vas deferens
- Urethra
- Seminal vesicles
- Prostate gland
- Cowpers gland
- Penis
4Penis - 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
6testes 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
7vas deferens tubes that go from the epididymis
to the urethra a passageway for sperm
8semen (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
tail
10Path 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
11ejaculation the action that forces semen
through the urethra out of the body

13Healthy 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.
14Problems 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
191. 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.
202. List the external and internal male
reproductive organs.
- External organs
- Scrotum
- Testes
- penis
- Internal organs
- Vas deferens
- Seminal vesicles
- Prostate glands
- Cowpers glands
- Urethra
213. 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
224. 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.
235. 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
246. 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
