Granulocyte colony-stimulating factor in assisted reproductive technology treatment does not increase the risk of adverse perinatal outcomes in twin pregnancies.

The aim of the study is to compare the perinatal outcomes of twin pregnancies resulting from assisted reproductive technology (ART) treatment in which granulocyte colony-stimulating factor (G-CSF) was used with those in which it was not. In this retrospective study, the clinical data of 122 dichorionic diamniotic twin pregnancies were reviewed. Pregnancies were divided into two groups, G-CSF-treated and non-G-CSF treated. Maternal age, gestational week at birth, oligohydramnios, gestational hypertension, pre-eclampsia, preterm birth, first-trimester bleeding, gestational diabetes, rupture of membrane, foetal congenital anomalies, admission to the neonatal intensive care unit, birth weight (BW), small for gestational age, BW discordance, Apgar score and placental weight were compared between the groups.IMPACT STATEMENT What is already known on this subject? Granulocyte colony-stimulating factor (G-CSF) administrations increase pregnancy outcomes and do not have a negative effect on perinatal outcomes in singleton pregnancies. What the results of this study add? This study showed that the perinatal outcome of dichorionic diamniotic twin pregnancies conceived after assisted reproductive technology (ART) treatment was similar in the GSF administrated and non-GSF administrated groups. What the implications are of these findings for clinical practice and/or further research? Using G-CSF to increase the success of ART does not seem to have an adverse outcome in the dichorionic diamniotic twin pregnancies.
