is
produced
in
the
small
seminiferous
tubules
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
goes
into
a
larger
tube
called
____________________
____________________
,
which
eventually
carries
them
to
the
external
male
reproductive
organ
,
the
____________________
.
Along
the
way
,
sperm
is
nourished
by
a
sugary
fluid
from
the

,
a
chemical
fluid
from
the
prostate
which
is
the
most
common
site
of
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

,
the
fluid
ejaculated
from
the
penis
during
____________________
.
Before
a
male
can
ejaculate
the
spongy
tissue
surrounding
the
penis
becomes
engorged
with
blood
causing
the
penis
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
