The influence of age and season on fecal dehydroepiandrosterone-sulfate (DHEAS) concentrations in Japanese macaques ( Macaca fuscata )

Highlights • We examined the potential influence of age and season on fecal DHEAS concentrations among female Japanese macaques. • DHEAS concentration was negatively correlated with age. • Season had no effect on DHEAS concentrations. • Elevated neonatal DHEAS is possibly a residue from fetal adrena...
