A study in 2013 examining a total of 2.3 million individuals born in Sweden in 1950-1970, using government health care records, found evidence for substantially lower fertility among sufferers of various mental illnesses. The fertility of the mentally ill was computed by measuring the fertility ratio (e.g. a FR of .5 would mean that the diseased group had on average half of the children of the general non-affected population, a FR of 2 would mean double the offspring on average) which reflected the mean number of children that individuals with various mental disorders had, as compared to control individuals of the same age and sex, also accounting for variables such as family size, affected status and parental status. The youngest individuals involved, at the time their data was recorded, were 40 years old, and had thus likely largely completed their reproductive careers. | A study in 2013 examining a total of 2.3 million individuals born in Sweden in 1950-1970,<ref>https://incels.wiki/w/Scientific_Blackpill#Mental_disorders_significantly_reduce_male_fertility.2C_substantially_more_than_they_do_for_women</ref> using government health care records, found evidence for substantially lower fertility among sufferers of various mental illnesses.

The researchers found evidence of substantially strong selection pressure against autism with a male FR of .25 vs a female FR of .48. Since there is evidence that female autism is underdiagnosed due to the condition being stereotyped as male,<ref>https://www.theguardian.com/society/2018/sep/14/thousands-of-autistic-girls-and-women-going-undiagnosed-due-to-gender-bias</ref> it is even conceivable that many milder cases of autism in females go unnoticed, who presumably have higher reproductive success. This should imply that these figures only give us a lower bound on the sex difference in how autists are sexually disadvantaged. | The researchers found evidence of substantially strong selection pressure against autism with a male FR of .25 vs a female FR of .48.
