Okay this might sound a bit weird I was wondering

Patient: Okay this might sound a bit weird… I was wondering if a girl could get pregnant without having sex. It’s not for me really… I’m 15 years old and i’m sort of trying to write a book where a girl gets pregnant without having sex WHAT SO EVER. Like never even being naked near a guy. So I guess my question would be this: is there a condition where a girl would have both the male and the female sex organs or something like that which would cause her to get pregnant on her own? Is there a certain disease like that?
