3. What is puberty?
 Puberty is the time in life when you begin to
become an adult. This means a lot of changing and
growing – both inside and out.
 Some of the changes that happen in puberty are
also known as adolescence.
 Puberty starts because of sex hormones (chemicals
in our bodies that send messages about our
development).

4. Changes in boys
 Penis & testes size ( or willy & balls)
 Body & facial hair
 Pubic hair (the hair around our sex organs)
 Body shape
 Voice change (or voice breaking)
 Body odor (our smell) & acne (spots)

5. Changes in girls
 Breast development
 Body hair (e.g. on our legs, arms,
underarms) & pubic hair (the hair around
our sex organs)
 Menstruation (a monthly bleed or period)
 Body shape
 Body odor (our smell) & acne (spots)

6. Differences amongst boys
 Penis & testes:
– All look different and vary in size and shape
 Body & facial hair:
– Some men have lots of facial hair, while others have very little
– Not all men develop chest hair
 Pubic hair:
– Like the hair on our head, pubic hair varies in colour and thickness
 Body shape & muscle:
– Growth spurts happen to different boys at different times and in
different ways; people are all different shapes and sizes
– One side of the body might develop faster than the other
 Voice change:
– Happens to different boys at different times and in different ways;
everybody sounds different.
 Body odour & acne:
– Both result from an increase in hormone levels and affect everyone
differently.

7. Differences amongst girls
 Breast development:
– Breasts are all different shapes and sizes
 Body hair & pubic hair:
– As with boys the colour and thickness of body hair and pubic hair varies
between girls
 Menstruation (a monthly bleed or ‘period’):
– Girls can start their period within a big range of ages; it could be at age
8, or it could be at 16
– No two girls’ periods are exactly alike, some last 2 days, others a week
 Body shape:
– Hip size varies between girls, as does overall size and shape
 Body odor & acne:
– Just like boys, odor and acne result from an increase in hormone levels
and affect everyone differently
