Essentially. what these studies are concluding is that:

• there are marked gender differences in women and men when it comes to autism spectrum disorder or asperger's syndrome
• women may not always exhibit outwardly 'odd' behaviors, like men. This leads to a bias in diagnoses.
• lack of a 'female phenotype' when it comes to autism or asperger's
• most current autism or asperger's research is based in the male experience, therefore, it's harder to diagnose women when their symptoms have not been researched

Therefore, this paper proposes that there should be more research done on the female phenotype in autism.
