About this trial
This study seeks to validate the hypothesis that nulliparous pregnant women after Assisted Reproductive Technology (ART) are at high risk of preeclampsia and perinatal complications and represent a subgroup for which aspirin prophylaxis during pregnancy may be effective in the prevention of preterm preeclampsia and other perinatal adverse outcomes.
