Hauora?
Hauora is another way of discussing your total well-being. When one area is affected by a
change or an activity, the other 3 are also affected. Think of Hauora as being like a
house.
When all four areas of Hauora
are strong, your total well-being
is strong.
We can relate this to all four
walls of the whare being strong
so the roof is stable.
When one area of Hauora is
weakened, it affects the other
areas of your Hauora
This can relate to one wall of
your whare being taken away
to be changed. The other
three walls are weakened or
changed which makes it
harder to support and hold the
roof up.
How can your Hauora become influenced by Puberty??
Physically: Your body organs, skin, bone and muscle development etc.
Spiritually: How do you value yourself? You’re surroundings? You’re learning of puberty?
Socially: How you interact with others
Mentally / Emotionally: How you are feeling and how your hormones are reacting to
things going on.
Changes of Puberty
Puberty is a time where there are many changes that occur in the body. These are
triggered by hormones. When puberty is complete, a male and female are physically able
to create a baby. Puberty is a time when people can have many different feelings about
their sexuality and to whom they are attracted too; because of this it is important not to
rush into any decisions about your sexuality.
Activity

Male Reproductive System
The male reproductive system is designed to produce sperm cells. So a new life begins
(i.e. a baby starts to form) when a male sperm cell fertilises an egg released by a female.

The Male Reproductive System
Using the words below, fill in the blanks below to make this explanation of the male
reproductive system correct. Each is only used once.
Cowper’s glands
epididymis
erection
nocturnal emissions
orgasm
penis
prostate
scrotum
semen
seminal vesicle
sperm
testes
urine
urethra
vas deferens
First, _______________________ are produced in the small seminiferous tubes of
the ________________. These oval shaped glands are protected by a sac called
the _____________________. After the sperm cells are produced, they are stored
in a large coiled tube on the outer surface of each testicle called the
___________________________. From this tube the sperm go into a larger tube
called the ___________________ ________________________, which eventually
carries them to the external male reproductive organ, the ___________________.
Along
the
way
sperm
is
nourished
by
a
sugary
fluid
from
the
_____________________ _____________________, chemical fluid from the
________________________ which is the most common site for cancer in men,
and fluid from the _____________________ ____________________ which are
two small glands, located near the bladder. These fluids plus the sperm cells
combine to form ________________________. This is the fluid ejaculated from
the penis during _____________________________. Before a male can
ejaculate, the spongy tissue in the penis becomes filled with blood, causing it to
become stiff and hard. This is known as an ___________________________.
The tube that carries the semen from the body is the ______________________.
This tube also carries _______________________ from the bladder. Males can
also
have
uncontrolled
ejaculation
during
sleep
which
are

Activity
1. Label the different parts of the female reproductive system in the following diagram
using the list of terms provided.
List of Terms

_____________________
_______________
___________________
Holds about
250,000 eggs. At
puberty they start
being released
once per month.
An egg (ovum) travels
through one of these tubes
to get to the uterus after
ovulation

First, _______________ __________________ are produced in two almond
shaped organs known as the _____________________. During the process of
_______________________, a mature egg
(____________) is released enters one of two ____________________
_________________. For a few days the egg travels toward the pear shaped

is
not
fertilized
by

male
_________________
_______________, it will leave the body together with the lining of the uterus and
a small amount of blood. This is called _________________________.
The lower portion of the uterus is called the ____________________ and is a
common site of cancer in women. The female sex organ is the _______________.
A circular fold of skin is usually present at the entrance to this called the
__________________. Outside of the vagina are folds of skin covered in pubic
hair known as the ______________________. Between these folds is a small
round sensitive area of skin called the ____________________.
The development of the reproductive system is triggered by the hormones
____________________ and ____________________, which cause many
physical changes in a girl. This period of change is called ___________________.
Did you know?
Girls are born with all eggs they need.
About 1 million all together
An egg is the size of a full stop. Sperm are
about 0.05mm long. One million sperm
can fit into the head of a pin
Ejaculated semen contains about 300
million sperm in 5ml of fluid
(1 tea spoon)
Sperm have to travel about 12cm to meet an egg.
At fastest this takes about 40 minutes
Sperm travel to an egg by
swimming
Period pain is caused by uterus contracting to expel the egg
and uterine lining.
In males about 70 million
In girls it’s normal for one
breast to be slightly larger
than the other. In boys it’s
normal for 1 teste to be a
different size
sperm are produced each
day
Eating chocolate doesn’t cause pimples,
but good nutrition is important to
prevent them
True or False
Eating lots of junk food causes pimples
Sometimes boys can develop breasts during puberty
People experience changes in their moods as well as changes in their bodies
It’s OK to have strong feelings for another person – boy, girl, friend or adult
You can always tell when a girl has her period
Most girls will have started having periods by the time they are 16
If a boy has an erection in public, it shows that he is thinking about sex
A girl can’t get pregnant before she has her first period or when she is
menstruating
A girl’s second period will come exactly one month after her first period
Once a boy has had a wet dream, it is possible for him to become a father if he
has sexual intercourse
A girl can increase the size of her breasts by doing lots or arm exercises.
If a boy masturbates too much, he will use up all his sperm
There is nothing wrong if one testicle hangs lower than the other.
1. Eating lots of junk food causes pimples.
Pimples occur during puberty, when an increased amount of sebum is produced.
Sebum is a natural, oily secretion that acts as a lubricant for the hair and skin. The
testosterone, oestrogen, and progesterone hormones released during puberty make the
sebum thicken, causing it to block the pores, which results in blackheads and pimples.
2. Sometimes boys can develop breasts during puberty.
Hormones can cause boys to start developing "breasts", but when the hormones settle
down, these "breasts" will disappear.
3. People experience changes in their moods as well as changes in their bodies.
Feeling good one minute and down the next is very common during puberty. People
gradually become less moody as they get used to their adult body and the new feelings
that come with it.
4. It's OK to have strong feelings for another person - boy, girl, friend, or adult.
Such strong feelings (or "crushes") are part of growing up.
5. You can always tell when a girl has her period.
Sanitary pads and tampons are made so that they do not show through clothing. Some
women feel irritable before, during, or after their period, but they may have similar
moods at other times too.
6. Most girls will have started having periods by the time they are 16.
Menstruation can begin between the ages of 8 and 17. If a girl has not had her period
by the age of 16, medical advice should be sought.
7. If a boy has an erection in public, it shows that he is thinking about sex.
During puberty, erections may happen to boys when they have no conscious sexual
thoughts at all.
8. A girl can't get pregnant before she has had her first period or when she is
menstruating.
It is possible for a girl to become pregnant if she has sexual intercourse before her
periods have started, and it is also possible to become pregnant from having sexual
intercourse while menstruating.
9. A girl's second period will come exactly one month after her first period.
When girls start menstruating, their menstrual cycles are often not very regular. They
may only menstruate three or four times in the first year.
10. Once a boy has had a wet dream, it is possible for him to become a father if he
has sexual intercourse.
It is possible, but it is not very likely. The first few wet dreams a boy has may not contain
any sperm but just seminal fluid. As puberty advances, the testes start to produce
sperm, which is then ejaculated in wet dreams.
11. A girl can increase the size of her breasts by doing lots of arm exercises.
Underneath the breasts are pectoral muscles, but developing these muscles cannot
increase the size of the breasts, because breasts are made up of glands and fatty
tissue. (Note: When exercising, girls may need to wear supportive clothing.)
12. If a boy masturbates too much, he will use up all his sperm.
The testes are continuously producing and replacing sperm.
13. There is nothing wrong if one testicle hangs lower than the other.
One testicle hangs down lower than the other for nearly all boys and men.
14. It's safe for a girl to touch her pubic area.
Girls need to touch their pubic area as part of their daily washing routines. Neither boys
nor girls should be afraid of masturbating or worry about it.
15. There is nothing wrong with a penis if it is curved or hangs to one side.
Penises vary in size and shape.
16. It is OK to flush all sanitary pads and tampons down the toilet.
Sanitary pads and tampons are very absorbent and can swell to block the toilet pipes.
Disposal bins should be used if they are provided. If they are not provided, then pads
and tampons can be wrapped in toilet paper and put in a rubbish bin.
