U.S. Health Secretary Robert F. Kennedy Jr. has recently sparked controversy by linking early childhood circumcision to a doubled rate of autism, attributing this connection to the administration of Tylenol – which is paracetamol in this country – during the procedure. Making these remarks during a Cabinet meeting, Kennedy suggested that the pain relief given at the time could be a significant factor in the increased autism diagnoses observed among circumcised boys. This latest claim builds on the current administration’s unsubstantiated narrative that prenatal exposure to Tylenol during pregnancy may contribute to autism. However, experts and health professionals widely reject these assertions due to a lack of credible scientific evidence supporting them.
Kennedy’s remarks appear to draw loosely on a 2015 study published in the Journal of the Royal Society of Medicine, which identified a higher prevalence of autism diagnoses among circumcised boys. Notably, this study did not suggest any causative link nor did it examine the role of painkillers such as paracetamol, making Kennedy’s leap to associate the medication with autism particularly tenuous. Several autism researchers, including Helen Tager-Flusberg, have criticised the methodological quality of the studies Kennedy cited, describing them as fundamentally flawed and cautioning against conflating correlation with causation in complex neurodevelopmental conditions like autism. As Scientific American highlighted, these studies have been thoroughly discredited by the scientific community for their lack of rigorous evidence.
The conversation around autism also intersects with LGBTQ+ identities. Research indicates higher rates of gender variance among autistic individuals, and similarly, transgender and nonbinary people show higher rates of autistic traits compared to their cisgender peers. This overlap has increasingly influenced contentious legislation, such as restrictive policies requiring autism evaluations before diagnosing gender dysphoria in transgender youth. While there is no evidence that autism causes transgender identity or vice versa, studies from institutions like the University of Cambridge suggest that autistic people, particularly women and girls, are more likely to identify along diverse sexual orientations or gender spectrums.
Mental health advocates and parents of autistic children have expressed frustration at the focus on speculative causes of autism at the expense of pragmatic support and social inclusion. As the debate unfolds, it remains critical for public health messaging to rely on robust scientific consensus and to prioritise the lived experiences and dignity of autistic individuals over unproven theories.
