Premature Adrenarche Adrenarche is the presence of pubic hair before 8 years of age in girls and 9 years of age in boys. It may be associated with the development of axillary hair and adult axillary odor. It is a benign condition that requires no treatment. There is premature production of increased amounts of dehydroepiandosterone in the adrenal. Higher incidence in African American females.
Some endocrinologist suggest all children be evaluated.
Children should be followed carefully to make sure that other secondary traits don't develop and that there is no abnormal growth acceleration. References Pediatrics in Review. Pediatrics in Review.
