A minor note of correction: though the 105/100 male/female ratio is broadly true for the world at large, there are substantial differences based on geography and possibly genetics. The most significant difference occurs in Africa, where the 105/100 ratio gradually transforms through the Sahel region to 104/100 and down to 103/100 throughout the sub-Saharan African region. The 103/100 ratio also occurs in Haiti (as seen by the sex ratio for the age range 0-4 in the US Census Bureau International Database or IDB) and amongst the black population in the United States (http://infoplease.com/ipa/A005083.html) -- showing that this is probably genetic in origin.

A second variation, of geographic origin, is also seen in a distinct tendency for the ratio to increase further north. The largest ratios, by far, (for the 0-4 age range) in the IDB is from Norway 1989-1991 (130/100). The ratio has tended to go up to around 107/100 to 110/100 for countries in Northern Europe (until recently), and in the northern part of the Far East (Korea, China). The north-south gradation is also seen in striking contrast in India, when the displayed is graphed on a state-by-state basis.

The question of the increasing incidence of special education diagnoses may ultimately be related to the more fragile nature of the genetics underlying the male genome -- an issue that's received recent airplay (particularly from Brian Sykes, Steve Jones) with forecasts about the ultimate loss of viability of the Y (throughout the mammalian world), and with books like Adam's Curse.

Another condition of note that shows a higher tendency for males, as well, is the spectrum disorder known as Asperger's Syndrome: a form of autism also commonly associated with unusual genius.
