| Résumé : |
Autism Spectrum Conditions (ASC) are strongly biased towards males, with a male:female ratio of 4:1 for classic autism and over 10:1 for Asperger Syndrome. The cause of the observed sex difference in ASC remains a topic of debate. The Extreme Male Brain (EMB) theory proposes that autism is an exaggeration of typical sex differences in empathizing and systemizing. Although this theory originally defined the ‘male and ‘female’ brain purely in psychometric terms, it has since been suggested that increased levels of prenatal androgens (particularly testosterone) may produce excessive masculinization of the brain and thereby increase the risk of ASC. An important candidate mechanism for the development of sex-typical behavior is exposure to hormones such as testosterone during pregnancy. Evidence that elevated testosterone levels may be a risk factor for ASC is discussed. |
