Why are extra X chromosomes in females not considered a problem?

Not a problem from a reproductive standpoint or from a morphological standpoint but those with the XXX or with XXX mosaic syndrome who have intellectual developmental issues may beg to differ. Issues are not nearly as profound for XXX trisomy as for their XXY male counterparts. The effects of trisomy can vary considerably from person to person.
