Tylenol use in pregnancy may be linked with uterus, ovary changes in daughters: Study
Researchers found later pregnancy paracetamol exposure was linked to 23% fewer ovarian follicles in baby girls, while doctors said the drug remains safe when needed.
- A new study published Wednesday in Human Reproduction Open found girls exposed to acetaminophen in the womb had, on average, 40% smaller ovarian volume, 13% smaller uterine volume, and 23% fewer ovarian follicles.
- Scientists in Denmark enrolled 685 women during the first trimester of pregnancy, evaluating 302 of their baby girls at 3 months old to assess reproductive development.
- While noting the findings are "impressive," Dr. Hugh Taylor of the Yale School of Medicine cautioned that the study does not establish acetaminophen exposure causes reproductive organ changes.
- The American College of Obstetricians and Gynecologists maintains acetaminophen remains the safest medication for pain or fever during pregnancy, advising use only in moderation.
- Last year, acetaminophen became a political issue when President Donald Trump urged pregnant women to "tough it out" regarding pain, despite established medical consensus supporting the drug's safety.
