Sex is a universal individual difference, not a regional one.  In that
sense, there should be no need to adjust sample size to reflect regional
sexual representation.  The tacit assumption is that, no matter how many
men and women there are in the region of test application, now and
forever, whatever potential differences in test performance there may be
between the sexes, should hold.

Besides, if the tests in question rely on some form of deviation score,
radically different subsample sizes would have an impact on the magnitude
of the standard deviation for each sex.
