Abstract: The assisted reproductive technology （ART） has met the demands of many infertile couples. With the development of new methods of ART and the increasing population of children conceived via ART，the safety of ART gets more and more attention. In this review，the relationship between ART and pregnancy complications, as well as diverse obstetric outcomes, was discussed. It is suggested that there were increased incidences of hypertensive disorders in pregnancy，obstetric hemorrhage, and gestational diabetes mellitus following ART. In addition，ART children had increased risks of premature，low birthweight, and birth defect. The mechanism of these obstetric outcomes related with ART have not been elucidated; however，those maternal or paternal subfertility may be an important factor. Women with ART pregnancies should get more antenatal care, and give the necessary prenatal screening and diagnosis, so as to have better maternal and perinatal outcomes.
