The
pill
is
ingested
through
the
mouth
and
it
releases
progesterone
that
disrupts
the
normal
cycle
making
implantation
difficult
so
the
girl
won’t
get
pregnant.
The
male
condom
is
a
latex
sheath
fitted
over
the
penis
that
traps
the
sperm
so
it
won’t
go
into
the
vagina,
and
it
also
protects
people
against
STDs.
The
vasectomy
mean
cutting
and
tying
up
the
vasa
deferentia
so
there
are
no
sperms
in
the
sperm.
Women
sterilization
is
cutting
and
tying
the
oviduct
so
there
are
no
oocytes
in
the
oviduct,
so
there
is
no
fertilization.
Contraceptives
are
very
important
in
society
because
they
help
prevent
unwanted
pregnancy,
and
most
importantly
some
of
them
help
prevent
the
spread
of
STDs,
so
young
people
don’t
have
to
go
through
them
and
experience
them.
Knowing
how
these
contraceptives
work
and
why
they
are
so
important
is
very
useful
information
nowadays
and
every
teen
should
at
least
be
aware
of
them.
