Compared with their non-autistic peers, young autistic girls have a thicker cortex that thins more quickly with age.

The Gender Self-Report could help autism researchers include more gender-diverse people across a range of ages and neurotypes in their work.

Male rats prenatally exposed to a maternal immune response have atypical responses to other rats in distress, according to a new study.

Common diagnostic and research practices may be adding to autism’s sex bias, but there are some simple steps scientists can take to counteract it.

Such high expression levels may account for the condition’s sex bias, a new preprint suggests — but not everyone agrees with that logic.

The function of microglia and astrocytes in the brain may mediate the intersection of sex-differential biology and autism biology.

The findings, based on Swedish national registry data, suggest a critical need to expand mental health services for autistic people.

The rare variants are also linked to ADHD and Tourette syndrome, two other conditions that disproportionately affect boys and men.

Siblings of autistic females are more likely to have autism than siblings of autistic males are, and mothers of autistic children carry more common, autism-linked variants than fathers do.

The male sex bias in autism may in large part be a product of how common diagnostic tools measure traits in boys versus girls at a single point in time, according to a new study.
