Abstract

Testosterone was assayed in the saliva of 32 female and 42 male 3-5 month old infants, and the lengths of their finger segments between flexion creases were measured. While expected sex differences were identified in the finger measures, these sex differences were not correlated with salivary testosterone in either sex.
