____________________
,
diagnosing
amenorrhea
is
a
matter
____________________
first
determining
whether
pregnancy
is
the
etiology
.
In
the
absence
of
pregnancy
,
____________________
challenge
is
to
determine
the
exact
cause

a
workup

amenorrhea
should
start
.
Secondary
amenorrhea
is
defined
____________________
the
cessation
of

menarche
has
occurred

Oligomenorrhea
is
defined
as
menses
occurring
____________________
intervals

No
consensus
has
been
reached
regarding
the
point
at
which
oligomenorrhea
becomes
amenorrhea

authors
suggest
the
absence
of
menses
for
6
months
constitutes
amenorrhea
,
____________________
the
basis
____________________
this
recommendation
is
unclear
.
For
a
post
-
menarchal
girl
or
a
reproductive
-
aged
woman
to
experience
a
menstrual
cycle
interval
of
more
than
90
days
is
statistically
unusual
.
Practically
speaking
,
this
should
be
____________________
indication
for
an
evaluation
____________________
seek
the
cause
.
