Summary

Story summary

Danish researchers found prenatal paracetamol exposure linked to 40% smaller ovarian volume in infant girls.
The study of 302 three-month-old girls reported 13% smaller uterine volume and 23% fewer follicles in exposed.
Exposure before 17 weeks correlated with lower Anti-Müllerian hormone and smaller uteruses at puberty in 1,210 girls.
Authors stress the results do not prove causation, cannot predict fertility, and European and UK guidelines endorse paracetamol in pregnancy.
