Robert F. Kennedy Jr. highlights research connecting circumcision to elevated autism rates.

Topics covered
During a recent cabinet meeting, Robert F. Kennedy Jr., Secretary of Health and Human Services, made a provocative claim about the connection between circumcision and autism. He cited two studies suggesting that infants who undergo circumcision may face an increased risk of being diagnosed with autism spectrum disorder.
Kennedy proposed that this risk could be linked to the use of acetaminophen, commonly known as Tylenol.
His remarks have sparked considerable debate about the implications of early circumcision and pain management in newborns. Many are questioning how these practices might affect long-term neurodevelopmental outcomes.
Understanding the claims and studies
Kennedy’s comments came after a press briefing in which the administration highlighted concerns regarding acetaminophen use during pregnancy and its potential links to autism diagnoses in children. Although he did not provide details on the specific studies he cited, a significant research paper from 2015 examined data involving approximately 340,000 boys.
This study found that circumcised boys had a 46% higher likelihood of receiving an autism diagnosis compared to their uncircumcised counterparts.
Clarifying the relationship between circumcision and autism
While Kennedy suggested a connection between circumcision and autism, the studies cited primarily focused on how pain management affects developmental issues, without specifically mentioning acetaminophen. Health officials clarified that Kennedy’s comments pertained to infants and indicated that the post-procedural use of Tylenol might contribute to the observed autism rates, rather than circumcision itself.
This distinction is critical because the research associating autism with circumcision is mostly observational and fails to establish a clear causal link. Other factors, such as parental health behaviors and environmental influences, may significantly impact these findings.
Public response and ongoing debates
Following his recent comments, Kennedy utilized social media to claim that the mainstream media mischaracterized his statements. He emphasized that his assertions were grounded in studies suggesting a doubled autism rate among circumcised infants. This increase may be linked to the use of post-operative analgesics such as acetaminophen.
The Trump administration, where Kennedy holds a position, has pledged to investigate the rising rates of autism in the United States. This increase has been significant, surging from a prevalence of 1 in 1,000 children in the 1980s to about 1 in 31 today. The dramatic rise has led to heightened scrutiny of various potential contributing factors.
The complexities of acetaminophen use during pregnancy
On September 22, President Trump advised pregnant women against using acetaminophen due to its potential association with autism. He urged expectant mothers to avoid Tylenol unless absolutely necessary, emphasizing the need for caution. However, experts stress that while some studies suggest a connection between acetaminophen use during pregnancy and autism, the evidence remains inconclusive.
The American Academy of Pediatrics has noted that the advantages of circumcision often outweigh the associated risks. Hospitals typically recommend pain relief options like Tylenol for infants undergoing such procedures. Nevertheless, this situation has prompted further examination of whether acetaminophen could impact neurodevelopment.
Expert opinions on the debate
Dr. Jeff Singer, a senior fellow at the Cato Institute, highlighted the ongoing research into whether acetaminophen might affect autism risk. He underscored that such investigations should remain within the realm of scientific and clinical experts, avoiding political influence. At the same time, Dr. Mehmet Oz, the director of Medicare and Medicaid Services, noted that it is generally safe for pregnant women to take Tylenol if advised by a healthcare provider.
The conversation surrounding circumcision, acetaminophen, and autism is intricate and multifaceted. While researchers are exploring potential links, it is essential to rely on rigorous scientific inquiry for drawing conclusions. As studies progress, public health officials and parents must carefully evaluate the evidence available to make informed choices about infant care and health.
