Abstract:
Objective To compare perinatal outcomes of the singleton and twin pregnancies , and explore risk factors associated with twin pregnancies. Methods The data of 1 026 patients in single and twin pregnancies treated with IVF/ICSI between January 2014 to March 2015 were retrospectively analyzed. Results The early miscarriage rate and early pregnancy loss rate in the singleton group was significantly higher than the twin group (16% vs 5.41%; 16% vs 6.98%) and the late abortion rate in the singleton group was significantly lower than the twin group (1.93% vs 7.12%), but the total pregnancy loss rate was not significantly different between the groups. The premature delivery rate in the twin group was significantly increased (9.19% vs 41.89%), the term taking-baby-home rate was significantly lower (56% vs 37.89%), but the total taking-baby-home rate was significantly higher in the twin group than the singleton group. The low weight delivery rate in the twin group was significantly increased (1.2% vs 14.8%), but the rate of birth defects was no significantly different between the groups. There were significant differences in age and number of embryo transfer between the two groups. Conclusions Twin pregnancies may increase the risk of late abortion and premature delivery and low weight delivery significantly. Age and number of embryo transfer may be the risk factors for twin pregnancies.
