The Unexpected Connection Between Estrogen and Autism | SciShow News

Researchers have long struggled to understand the distinct brain development in individuals with autism spectrum disorder (ASD), particularly since it is more prevalent in boys. Previous theories linked high prenatal testosterone to ASD, but recent findings from Cambridge and Danish scientists suggest estrogen may play a significant role instead. They analyzed amniotic fluid samples and found elevated levels of estrogen, especially estradiol, correlated with a higher likelihood of autism diagnoses in male fetuses. This research challenges the traditional focus on male hormones, indicating that prenatal estrogen might influence brain development in ways that contribute to autism traits. However, further studies are needed to explore these findings across genders and understand the complex interplay of genetics and hormones in autism development.
