The male reproductive system includes external organs like the penis and scrotum, as well as internal organs like the testes that produce sperm and testosterone. During puberty, the testes begin secreting testosterone which allows for erections and ejaculation. Problems that can affect the male reproductive system include impotence, infertility, hernias, and testicular cancer.

4. The Male Side
At birth, the penis has a covering of thin loose

Often, this foreskin is removed at birth. This
procedure is known as a Circumcision.
In the U.S. 60-70% of
baby boys are
circumcised.

5. To Circumcise or Not?
Research what cultures/ religions have
differing views on this subject.
Find at least three different
cultures/religions and what their views
are.

6. To Circumcise or Not?
Pros of Circumcision:
Can reduce the prevalence of HIV 
Sub-Sahara Africa = 68% decrease
Decreased risk of urinary tract
infections
No risk of infections surrounding
foreskin

7. To Circumcise or Not?
Cons of Circumcision:
May increase ________-
inflammation of the opening of
the penis
May decrease sexual satisfaction
for both partners

8. To Circumcise or Not?
There is major controversy over whether or

9. The Male Side
________: external skin sac that contains the testes
____________: are two small glands that produce
sperm

10. The Male Side
_________ is the male reproductive cell

11. The Male Side
The scrotum protects the sperm in the testes, it also
helps keep the sperm at 98.6 degrees F, or normal
body temperature.
If it’s too warm, the suspensory ligament and scrotum
muscles drop the testes down.
If it’s too cold, the opposite occurs, and pulls the
testes in closer to the body.

12. The Male Side
When puberty hits, the testes start to secrete ________
and producing sperm.
This increase in testosterone and the presence of
_________ results in the ability for males to
experience an erection.
An erection occurs when there is an increase in blood
flow to the penis.

13. The Male Side
Many different things can cause this increase in blood
flow, especially during pubescent years.
Even the friction of clothing can sometimes cause
arousal. This can be a cause of embarrassment for
many young males.

15. The Male Side
At the onset of sexual stimulation, the male reproductive
system begins producing pre-ejaculate fluid.
This fluid is a clear mucous like liquid produced and
secreted through the urethra in order to balance the pH
from the acidity of urine to a safe level for the passage of
sperm. This fluid can also serve as a natural lubricant.
On rare occasion, pre-ejaculate fluid may contain sperm.
Therefore, it is difficult to say that “withdrawal” (or withdrawing
the penis before full ejaculation) is a safe practice for
contraception.

16. The Male Side
When the male reaches the peak of sexual arousal, a
series of muscular contractions begin to occur.
These contractions bring the sperm through the
_______________, mixing it in with other things to be
secreted.

17. The Male Side
Eventually all is secreted through the penis
(more specifically the urethra) in a substance
called____________.
Semen is a thick white or greyish fluid that
contains sperm and other secretions from the
male reproductive system.
Other substances in semen include
_________, sugars, citric acid, and potassium.

18. The Male Side
The average volume of semen produced
in a single ejaculation varies from 2 to 5
ml.

19. The Male Side
The semen from a single ejaculation may
contain between ________________,
depending on the volume of the
ejaculate and the length of time since
the last ejaculation.

20. The Male Side

to push through the abdominal wall near the top of the
scrotum

29. The Male Side
Causes: Lifting heavy objects and or straining the
