Relevance for mental health professionals: The study highlights prenatal hormonal milieu, inferred from finger-length ratios, as a possible influence on early brain development. For clinicians focused on developmental trajectories, this work adds a biologically grounded context for variability in neurodevelopment that may shape later cognitive and behavioral patterns. A notable finding is that higher prenatal estrogen was linked to larger head size in newborn boys, suggesting sex-specific developmental pathways relevant to understanding early risk indicators.
