Tue Oct 21 13:36:08 UTC 2025: ## Kennedy’s Autism-Circumcision Claim Debunked by Experts
Washington D.C. – Claims made by U.S. Health and Human Services Secretary Robert F. Kennedy Jr. linking circumcision and autism have been widely refuted by experts who cite a lack of scientific evidence.
On October 9, Kennedy stated that studies suggested a correlation between early circumcision and a doubled rate of autism, potentially due to the use of acetaminophen (Tylenol) for pain relief. He referenced a 2013 and 2015 study, as well as a yet-to-be-peer-reviewed paper from WPLab, a company promoting a link between acetaminophen and autism.
However, a closer look at the studies reveals significant limitations. Neither study definitively proves a causal relationship between circumcision and autism. The 2013 study, a “hypothesis generating exploratory analysis,” merely explored a potential association between circumcision rates and autism prevalence in different countries. It didn’t track individual acetaminophen use and explicitly cautioned against drawing causal inferences.
The 2015 Danish study found a slight increase in autism risk among circumcised boys but had a small sample size and was criticized for methodological issues. Moreover, circumcision is rare in Denmark and primarily practiced by religious minorities, further complicating the analysis.
Experts emphasize that neither study considered other crucial factors like cultural background, demographics, or other potential influences on autism rates. Helen Tager-Flusberg, professor emerita at Boston University, emphasized the importance of considering such confounding variables when examining associations between risk factors and autism.
The WPLab paper cited by Kennedy has not undergone peer review, a standard process to ensure scientific rigor. It promotes the controversial claim that acetaminophen triggers autism, a view not supported by scientific consensus.
Decades of research have established acetaminophen as safe for infants and children when used as directed by a pediatrician, and there is no evidence to support a link between acetaminophen use in childhood and increased autism risk.
While infant circumcision is often performed with local anesthetics, some hospital guidelines advise parents to administer acetaminophen for post-procedural pain. The connection between acetaminophen and circumcision is not always consistent or directly linked.
Despite the lack of supporting evidence, Kennedy defended his statements, pointing to the WPLab paper and the 2015 study on social media. His claims have sparked concern among medical professionals who worry about the spread of misinformation regarding autism and common medical procedures.
