The study is unlikely to have significant direct market impact, but it may reduce public anxiety and potential litigation concerns related to circumcision and acetaminophen. It could slightly benefit companies involved in neonatal care and pediatric health by clarifying a debated issue.
A large U.S. cohort study published in JAMA Pediatrics on August 3 found no association between neonatal medical male circumcision and autism spectrum disorder (ASD) or autism-related traits. The analysis, led by Monica McGrath of the Johns Hopkins Bloomberg School of Public Health, examined 2,771 boys from the NIH-funded ECHO Cohort. After adjusting for confounders, circumcision was not linked to autism diagnosis (OR 0.83, 95% CI 0.59-1.17). The study was prompted by public comments from Health Secretary Robert F. Kennedy Jr. in September 2025, who claimed circumcised boys were twice as likely to develop autism due to acetaminophen use. The findings challenge earlier observational studies from 2013 and 2015 and provide reassurance to parents. Acetaminophen exposure was too rare to analyze. The study also found no association with autism-related traits or behaviors, and results were consistent across regions, preterm birth, and NICU admission.
