That is not how things work. Females are the main drive to reproduction and decide demographic trends in societies where they are not oppressed(also, diagnosed autism levels in minority grpups is higher compared to classical white populations - make from it what you want, but I will avoid comments for this here). And female autism works differently than male autism and a lot of that does not show up, because less females would be diagnosed for the very simple reason that diagnosis is not a disease but how well a person can function in society and females differ from males in that as they are doing better than males. We do not exaclty know variable for amount of females, that have "autistic" genes, but they seems to be main drive to spread autism and very successful at that, regardless how diagnosed male autists are multiplying less. Also, people seem to have wrong idea about how genes spread - it takes SINGLE successful case to spread dominant and successful genes over the next generations.

The main issue that people are thinking of autists, that they are somewhat different from other people - even on biological level and it does not help, that among autistic people there arte those that think in the levels of "autistic nation", because genetically we are even less different to other humans than a lab rat to other rats. And like I mentioned before, spread of succesful autistic genes is irrevelant of the number of direct descendants that person produces, and with genes you can't assume, that they are only present to those that have diagnosis.
