Sex hormones may play a part in autism

A study found that autistic males have lower levels of estrogen receptors and aromatase, an enzyme converting testosterone to estradiol. This could lead to increased testosterone levels, potentially contributing to the disorder's prevalence in men. The findings suggest a possible reason for the gender bias in autism diagnosis.
