Study Finds Possible Link Between Tylenol Use in Pregnancy and Reproductive Changes in Baby Girls
What Happened
A new Danish study found that baby girls whose mothers used Tylenol (acetaminophen/paracetamol) during pregnancy had, on average, smaller ovaries and uteruses, fewer ovarian follicles, and lower reproductive hormone levels at three months of age compared with unexposed infants. The study tracked 302 baby girls and was published in Human Reproduction Open.
Key Takeaways
Researchers stress that the study does not prove Tylenol caused these changes and found no evidence of reduced future fertility. Medical experts and the American College of Obstetricians and Gynecologists said the findings do not change current recommendations, and acetaminophen remains one of the few pain and fever medicines considered safe for use during pregnancy when needed.
