Though apparently it has a feminine form, eadem. I don't know enough about Latin grammar to know that girls should use that form, or if the form should be used with feminine subjects, or both.
It should be used if the thing to refer to is (grammatically) feminine. Considering that English (unlike Latin) doesn't differentiate between sexus (actual gender) and genus (grammatical gender), we could probably say that
eadem should only be used if the subject one refers to is actually feminine. Considering that we use
idem only to refer to posts, sentences or statements, which are all neutral, we should use the neutral form, which is identical with the masculine form (
idem).
(Small note: there are differences between the male and neuter form of
idem, for example, the masculine form actually has a long I, while the neuter has a short I, and if they are inflected, they differentiate even further (the plural nominative, for example, of the male form is
idem, but the one of the neuter form is
eadem).)
