Sperm
are
produced
in
males
from
the
age
of
puberty
to
old
age.
They
are
produced
in
the
testes
which
are
kept
cool
outside
the
body.
They
are
held
in
place
by
a
layer
of
skin
called
the
scrotum.
The
sperm
are
produced
in
millions
in
the
testes.
They
move
up
the
sperm
duct
(sperm
tube)
into
the
body,
and
pass
glands
which
add
liquids
and
nutrients.
The
sperm
then
become
active,
and
are
able
to
swim
like
tadpoles
by
flicking
their
tails
from
side
to
side.
The
sperm
are
stored
in
the
body,
and
pass
out
of
the
body
through
the
urethra,
a
tube
which
is
also
used
to
pass
urine.
The
sperm
and
liquids
are
now
called
semen,
and
contracting
muscles
force
the
semen
out
of
the
body.
This
is
called
ejaculation
and
happens
during
sexual
intercourse
(mating).
