When autism is mentioned, that mention will almost certainly include a statistic. One of the more common autism-related numbers thrown around these days is the fact that it is four times more likely to occur in boys than in girls. A less commonly discussed phenomenon in the autism community and in the greater mental health community is that autism spectrum disorders ASD occur at a higher rate in transgender people than in the general population. This trend, documented in dozens of case studies and prevalence studies , causes some uncertainty around the four-times-more-common-in-males statistic and raises questions about autism and gender identity. A study conducted by a team of British scientists in found that of a pool of individuals not diagnosed on the autism spectrum, female-to-male FTM transgender people have higher rates of autistic features than do male-to-female MTF transgender people or cisgender males and females.

Individuals on the Autism spectrum tend to be less influenced by or responsive to societal expectations or constraints. This natural inclination to be oneself and not follow the crowd or societal norms, seems to correlate with a higher than average incidence of individuals on the spectrum having greater variance and flexibility in the areas of sexual orientation and gender identity and expression. Many on the Autism spectrum do not subscribe to the prevailing binary definitions. This gender, assigned at birth, is determined by external genitalia and for the vast majority aligns with gender identity and expression. This is called being cisgender.
Sexual Orientation in Autism Spectrum Disorder
Males are more frequently diagnosed with autism than females. It is debated whether this is due to a sex difference in rates of autism spectrum disorders ASD or whether females are underdiagnosed. Several theories exist to explain the sex-based discrepancy, such as a genetic protective effect,    the extreme male brain theory   and phenotypic differences in the presentation between sexes,     which may all be intertwined.
People who do not identify with the sex they were assigned at birth are three to six times as likely to be autistic as cisgender people are, according to the largest study yet to examine the connection 1. Gender-diverse people are also more likely to report autism traits and to suspect they have undiagnosed autism. Cisgender, or cis, refers to people whose gender identity and assigned sex match.
