 Hines and Kaufman (1994) found that 50% of girls with CAH reported a preference for boys as playmates, while less than 10% of their non-CAH sisters preferred boys as playmates.Another study found that girls with CAH still preferred same-sex playmates, but their atypical play styles resulted in them spending more time alone engaging in their preferred activities.Girls with CAH are more likely to have masculinized genitalia, and it has been suggested that this could lead parents to treat them more like boys; however, this claim is unsubstantiated by parental reports.
