INTRODUCTION: Various factors related to an "in vitro" fertilization (IVF) procedure may influence the rate of small for gestational age (SGA) newborns in such pregnancies.
AIM: The aim of the study was to determine neonatal SGA incidence in singleton IVF pregnancies compared to spontaneous ones.
MATERIALS AND METHODS: We conducted both a prospective and a retrospective study within the period of January 2013-December 2017, which included 336 patients with a singleton IVF pregnancy at the time of delivery - the study group (SG), and 493 women with a spontaneous conception - the control group (CG).
RESULTS: Neonatal SGA rate was significantly higher in the SG as compared to the CG, p < .05, as well as in case of multiple embryotransfer (ET), vanishing twin syndrome (VTS), fresh ET against frozen embryotransfer (FET), female infertility factor.
CONCLUSION: Singleton pregnancies after an IVF technique show a higher neonatal SGA rate compared to spontaneous ones.
