A new study published in JAMA Pediatrics has found no link between male circumcision after birth and an increased risk of autism. The research was supported by the National Institutes of Health and analyzed data from a large nationwide project. The findings aim to reassure parents who were worried by earlier reports.
Public concern grew after older studies and media reports suggested a possible connection. At the same time, autism diagnoses in the United States have increased significantly over recent decades. According to health officials, autism rates rose from one in 150 children in 2000 to one in 31 eight-year-olds in 2022.
To test the connection, researchers examined data from 2,771 boys across 14 U.S. locations. About 66% of the boys were circumcised shortly after birth. The results showed an autism rate of 6% among circumcised boys, compared to 9% among uncircumcised boys.
After adjusting for family history and parental age, scientists confirmed there was no significant link. Researchers will now continue looking for other factors that might explain why autism diagnoses are increasing.
