Tylenol Use In Pregnancy May Reduce Daughters' Fertility, Study Finds

Female reproductive organ development could be impacted by a mother taking Tylenol - also known as acetaminophen or paracetamol - during pregnancy, according to researchers in Denmark.

On average, infant girls exposed to the pain relief drug in the womb had smaller ovaries; fewer ovarian follicles, which are the structures that contain immature eggs; smaller wombs; and lower levels of reproductive hormones, according to the findings of the study published Wednesday in Human Reproduction Open.

Long-term follow-up will be required to determine whether the differences observed in infants have implications for fertility later in life and a woman's age at menopause, study leader Margit Bistrup Fischer of Rigshospitalet in Copenhagen said in a statement accompanying the study.

Animal studies have previously suggested that fetal exposure to Tylenol, the most commonly used drug in pregnancy, might affect ovarian egg reserve and later reproductive function, but this is the first time that research has reported similar findings in humans.
