Genetics and environment likely contribute to the development of medically intractable epilepsy; however, in most patients the specific combination of etiologies remains unknown. Here, we undertook a multicenter retrospective cohort study of sex distribution in pediatric patients undergoing epilepsy surgery and carried out a secondary analysis of the same population subdivided by histopathologic diagnosis. In the multicenter cohort of patients with intractable epilepsy undergoing surgery regardless of etiology (n. = 206), 63% were boys, which is significantly more boys than expected for the general population (Fisher exact two-tailed p. = 0.017). Subgroup analysis found that of the 90 patients with a histopathologic diagnosis of focal cortical dysplasia, 72% were boys, giving an odds ratio (OR) of 2.5 (95% CI, 1.34 to 4.62) for male sex. None of the other etiologies had a male sex predominance. Future studies could examine the biological relevance and potential genetic and pathophysiological mechanisms of this observation.
