Abstract

OBJECTIVE
To compare the obstetric complications and perinatal outcomes of twin pregnancies conceived by In Vitro Fertilization and Embryo Transfer to twin pregnancies conceived naturally.
METHODS
Maternal and neonatal data were reviewed for all twin pregnancies. All twin pregnancies (n=116) were divided into IVF twin pregnancyes group (n=43) and naturally conceived twin pregnancyes (n=72). The obstetric and perinatal outcomes were compared and analysed. Statistical analysis was performed using student's t-test, x2 test, and Fisher exact test. Statistical significance was defined as p<0.05.
RESULTS
There were no significant differences in maternal age and gestational age between two groups but nulliparity was higher in IVF-ET twin group than naturally conceived twin group. Also no differences of obstetrics and perinatal outcomes were seen between two groups.
CONCLUSION
Although twin pregnancies following IVF-ET are more likely to result in bad prognosis, in this study obstetric and perinatal outcomes are comparable to those of naturally conceived twin pregnancies.
