Puberty
• Is the period in the developmental span
when the child changes from an asexual
to a sexual being
• Is derived from the Latin word pubertas
which means “age of manhood” [sic,
womanhood]
• “You're Entering Puberty, Charlie
Brown!” Please take down some notes
on the changes that are going on with
Charlie Brown
Rites of Passage
• Primitive people: observe rites of
passage, in recognition of the fact that,
as their bodies change, children are
emerging from childhood into maturity
(from National Geographic)
• After successfully passing the tests,
they are granted the rights and
privileges of adulthood and are
expected to assume the responsibilities
that accompany that state
Characteristics of Puberty
1. Puberty is an overlapping
period – encompasses the
closing years if childhood
and the beginning years of
adolescence.

Characteristics of Puberty
2. Puberty is a short period
– 2 years or less
- Girls tend to mature
more rapidly than boys
Characteristics of Puberty
3. Puberty is divided into 3 stages
a. Prepubescent stage – secondary sex
characteristics (organs not directly
responsible for reproduction) begin
to appear but the reproductive
organs are not yet fully developed
b. Pubescent stage – sexual maturity
appear, menarche in girls and
nocturnal emissions in boys
c. Postpubescent stage - secondary
sex characteristics become well
developed and the sex organs begin
to function in a mature manner
Characteristics of Puberty
4. Puberty is a time of rapid growth
and change - “adolescent growth
spurt”– may lead to confusion, to
feelings of inadequacy and insecurity
Characteristics of Puberty
5. Puberty is negative phase (by
Charlotte Buhler) – meaning, the
individual takes an “anti” attitude
toward life or seems to be losing some
of the good qualities previously
developed
Growth of research of
endocrinology
- 5 years before children become
sexually mature, there is a small
excretion of the sex hormones in
both boys and girls.
- Close relationship between the
pituitary gland, located at the
base of the brain, and the
gonads or sex glands
- Male gonads – testes
- Female
gonads - ovaries
