This focuses on the parts of male reproductive system and its function. You can download the lesson plan on this. I am not the composer of the song though. I just forget where I read it. Credits to the composer.

1. Male Reproductive
System
by:
DARYL F. CADANILLA

2. Objectives:
 Identify parts of male reproductive system
and their corresponding function
 Describe the pathway of sperm from
production to ejaculation
 Appreciate the role of male reproductive
system in the reproduction of human life

4. to the tune of
I WON’T GIVE UP
 By Jason Mraz

5.  When I look at vagina
I really feel so high
When I see the egg rise
An erection I hold
 Oh my dear testis,
I see that you’ve come so far
To be right where you are
How old are you sperm?

6.  I won’t give up on you
Even if your walls get rough
The energy I have for you Still swimming
up

And when you’re needing your space
To do some navigating
I’ll be here patiently waiting
To see what I’ll find

7.  Even if clitoris fade Or wrinkled it to the
earth
We got to travel lot
I know I can make it
 I won’t give up on you
Even if your walls get rough
The energy I have for you Still swimming
up

8. Who do you think
won’t give up in the
song?
What is his role in
human
reproduction?

9. Work by pair
 A video will be played and one of each
pair will take note on the different parts
of male reproductive system mentioned
and to where they are positioned.
 The other one will be taking notes on
the function of each part

10. Functions of the
Male Reproductive System
1. Produce and Store Sperm
2. Produce male sex hormone
testosterone

11. Physical Changes Male
• growth spurt
• acne
• deeper voice
• facial and body
hair develops
• broader
shoulders
• muscles get
larger
• perspiration
increases
• 1st ejaculation
occurs

12. External Structures
• Penis
• Male sex
organ
• Incase
urethra Penis

14. External Structures
• Scrotum
• Incase testes
• Control
temperature
of testes
Scrotum

15. Internal Structures
• Testes
• Make Sperm (50,000
sperm every minute)
• Produce the male sex
hormone testosterone
• Necessary for sperm
production and
development of the male
sex characteristics.
Testes

16. Internal Structures
• Epididymis
(on top of each
testicle)
• Sperm are
stored and
mature here
Epididymis

17. Internal Structures
• Vas Deferens
• Sperm travel
through here
• Tubes that
lead to the
urethra
Vas
Deferens

19. Internal Structures
• Urethra
• Semen travels
through here and
out the end of the
penis
• Urine flows
through here and
out the end of the
penis
Urethra

20. Internal Structures
• Seminal Vesicle
• Supplies fluid to
sperm
• Nourishes
sperm (sugar)
Seminal Vesicle

21. Internal Structures
• Prostate Gland
• Supplies fluid
to protect the
sperm
Prostate Gland

22. Internal Structures
• Cowper’s
Gland
• Bulbourethral
Gland
• Supplies fluid to
sperm to help
with mobility
Cowper’s
Gland

25. 4 Parts of Semen
• Sperm (300 to 400 million)
• Seminal Fluid – Nutrients (sugar)
• Prostate Fluid – Protection
• Cowper’s Fluid –
Mobility/Neutralize

26. Sperm Structure
• Composed of a head, mid-piece, tail
• Millions produced daily
• Head contains genetic information
•X or Y chromosome
•23 chromosomes

27. Sperm

30. How does erection
occur?
• Penis becomes
larger and
stiffer as blood
chambers in the
penis become
filled with blood

31. Ejaculation
• Ejection of semen from the penis
• Contractions occur at the base of the
bladder, forcing semen through the
urethra
• 1 ejaculation = 40-400 million sperm

32. Nocturnal Emissions
• “Wet Dreams”
• Ejaculation during sleep
• They are normal and may occur
frequently or it is normal if they never
occur

33.  What is the role of of male reproductive
system in the reproduction of human life?

34. Identify the parts that are involved in the travel of sperm from formation to
ejaculation. Write in order.

35. What causes prostate cancer?
What are its symptoms?
