Girls Exposed to Tylenol in the Womb Showed Surprising Changes, Study Finds
Newsweek • • health
Key Points:
- A Danish study found that girls exposed to paracetamol (Tylenol) in the womb showed differences in ovarian and uterine development markers from infancy through adolescence, including smaller ovarian and uterine volumes and altered hormone levels.
- The research, which followed 302 girls initially and was supported by a larger cohort of 1,210 girls, suggests prenatal paracetamol exposure may affect female reproductive development, but does not prove causation or confirm impacts on future fertility.
- Experts caution that the observed differences were small and based on markers rather than long-term reproductive outcomes, emphasizing that pregnant women should continue to use paracetamol only when necessary and under medical guidance.
- Lead researcher Dr. Margit Bistrup Fischer highlighted that while the findings add to concerns about paracetamol use during pregnancy, current medical advice remains unchanged, and decisions should be individualized in consultation with healthcare professionals.
- The study underscores the need for larger, long-term research to determine whether prenatal paracetamol exposure has clinically meaningful effects on female fertility later in life.
