Down syndrome is slightly more common among males with most studies showing about 106 to 125 boys for every 100 girls.
In some studies younger mothers, who have a lower total chance of having a baby with Down's syndrome, have a more skewed male:female ratio when they do (as high as 173 boys for every 100 girls).
No one is sure why boy are affected more often.
