I seem to recall that the statistics going back for
years and years consistently show that 51% of births
are boys, and that statistically, the mortality rates
for boys is also higher.

I understand that this slight edge may be due to the
fact that Y-type sperm swim slightly faster than the
X-type.  I do know that this difference in speed is
used to seperate the two types of sperm in the cattle
industry to guarantee the sex of calves produced by
artificial insemination.
