Objective: To evaluate the obstetrical outcome of in vitro fertilization and embryo transfer (IVF-ET) pregnancy.
Methods: This study compared the obstetrical outcome of 128 cases of IVF-ET pregnancy with that of 11,372 natural pregnancies as control group.
Results: There were 20.3%(26/128) multiple pregnancy, 20.3%(26/128) premature birth, 14.8%(19/128) pregnancy induced hypertension, 25.5%(41/161) small for gestational age, 88.3% (113/128) cesarean section rate and 31.1@1000(5/161) perinatal mortality in the IVF-ET group. However, these data in the control group were 3.3%(380/11,372), 1.0%(119/11,372), 7.6%(863/11,372), 3.6%(416/11,492), 34.7%(3,946/11,372) and 8.9@1000 (102/11,492), respectively.
Conclusion: The incidence of obstetrical complications was significantly higher in IVF-ET pregnancy. Multiple pregnancy is a high risk factor.
