Oct. 9 (UPI) -- Health and Human Services Secretary Robert, F. Kennedy Jr. claimed Thursday that there is a strong connection between circumcision and autism, and he linked the higher incidence of the condition to Tylenol.

"There are two studies that show children who are circumcised early have double the rate of autism, " Kennedy said during a Trump administration Cabinet meeting. "It's highly likely because they're given Tylenol.

Kennedy did not specify which studies he was referencing, but a 2015 report from Denmark that tracked 334,000 Gen Z males suggested that males who were circumcised were more likely to develop autism before the age of 10 than those who were not.

Acetaminophen, the active analgesic in Tylenol, is routinely used by pregnant women, but contraindicated by the Food and Drug Administration after 20 weeks gestation.
