Methods:According to the oxygen concentration of in vitro culture environment, the IVF-ET performed in the Women's Hospital, Zhejiang University School of Medicine during 2013 and 2015 were divided into low oxygen concentration group (n=2036, 5% O2) and high oxygen concentration group (n=4617, 20% O2). The rate of fertilization, good quality embryo, clinical pregnancy, ectopic pregnancy, abortion and birth defect were compared between two groups. Results:The good quality embryo rate was significantly higher in the low oxygen concentration group (P<0.05). However, no significant differences were found between two groups in the rate of fertilization, clinical pregnancy, ectopic pregnancy, abortion and birth defect (all P>0.05). Conclusion:Low oxygen environment may improve the potential of embryonic development, but its impact on pregnancy outcome and birth defect is not significant.
