Congenital adrenal hyperplasia. II. Cognitive and behavioral studies

Abstract
A sample of 31 patients with congenital adrenal hyperplasia was matched to a control group by sex, age, height, full-scale IQ score, and urban/rural site of residence. Patients and matched controls were tested on measures of masculinity and femininity and on sex-typed tests of cognitive ability. The two groups did not differ significantly on these measures. The finding is in disagreement with earlier reports of “masculinization” of behavior in female patients with congenital adrenal hyperplasia.
