Tylenol During Pregnancy Linked to Reproductive Changes in Baby Girls. Researchers say Tylenol use during pregnancy may be associated with reproductive organ changes in baby girls. However, the study does not prove the painkiller caused these differences or predict future fertility problems. The team examined 302 three-month-old girls whose mothers had Tylenol use monitored regularly throughout their pregnancies. Those exposed in the womb had smaller ovaries, fewer follicles, smaller uteruses and lower hormone levels. Girls exposed before seventeen weeks also showed lower Anti-Müllerian hormone levels, linked with ovarian egg reserves. A separate group followed into adolescence showed smaller reproductive organs after fetal Tylenol exposure during pregnancy. Researchers stress women should not panic, while untreated severe pain or fever can also pose risks. Long-term studies are needed to determine whether these early differences affect fertility or menopause eventually later.
