ABSTRACT
OBJECTIVE: The aim of this study was to evaluate and compare neonatal outcome of premature twins conceived by in vitro fertilization (IVF) to those of naturally conceived. METHODS: We retrospectively analyzed neonatal outcome of sixty pairs of premature twins conceived by IVF (IVF twin group) and 34 pairs that naturally conceived (natural twin group). Maternal and obstetric characteristics were also compared. All were born before 35 weeks of gestation between January 2000 and December 2004 at Pochon-Cha Hospital and admitted to neonatal intensive care unit. Student t-test and chi-square test were used for statistical analysis. RESULTS: For obstetrical characteristics, maternal age and rates of nulliparous were sibnificanty twin group. But, other parameters (preterm labor, premature rupture of membranes, pregnancy-induced hypertension, gestational diabetes mellitus) were similar between two groups. For neonatal outcome, gestational age, duration of hospital stay, Apgar score, neonatal mortality and morbidity were reviewed. All parameters were no significant differences in IVF twin group compare to natural twin group CONCLUSIONS: In our study, IVF twin group had no significant differences in obstetric characteristics (except for maternal age and parity) and neonatal outcome compare to natural twin group.
