Do identical twins get married less?

While having a twin might sound fun, a new study suggests that it could come with some worrying side effects. The study, by researchers from Northwestern Academy of Sciences , has revealed that women with a twin brother are less likely to marry, have children, or go to university.

What happens when identical twins have a baby?
