“Imagine you walked down the street and asked random people what autism is. What would they say? My guess: They’d talk about social skills, and the rising prevalence, and probably the vaccine nonsense. And they’d almost certainly mention that it happens to boys.
The idea that autism is a mostly male disorder is pervasive in the news, pop culture, and scientific circles. And it’s not just an academic curiosity. Last year a popular fertility clinic in Sydney, Australia, reported that about five percent of couples went through in vitro fertilization just so they could select a female embryo and thus lower the kid’s risk of developing autism.
The sex skew in autism is real: A diagnosis of autism is almost five times more common in 8-year-old boys than in 8-year-old girls, according to the latest statistics from the CDC.”
