The aim of this study is to describe obstetric and perinatal complications in pregnancies from oocyte donation (OD) cycles, delivering in our centre and to determine the impact of maternal age. Retrospective observational study of a 225 singleton pregnancies, 113 multiple pregnancies and 447 live birth. Pearson’s χ2 test or Fisher’s exact test were used for the statistical analysis. A higher incidence of obstetric complications was observed in multiple compared to singleton pregnancies with regard to preeclampsia (24.8% versus 8%), premature rupture of membranes (9.7% versus 1.8%), preterm delivery at <37 weeks (54.9% versus 10.2%) and caesarean section (81.4% versus 64%) (p < 0.05). If the age factor is added, the caesarean sections are higher in the single pregnancy group aged ≥40 years than in the group of <40 years (73.5% versus 49.4%) (p < 0.05). A higher incidence is found in multiple versus singleton pregnancies for low birth weight (<2500 g) (61.1% versus 8.2%), admissions to the intensive care unit (15.2% versus 4.7%) and perinatal mortality (13.5‰ versus 0‰) (p < 0.05). It is necessary to consider preconception counselling prior to an OD cycle to inform patients about the incidence complications observed and recommend to transfer only a single embryo. © 2015 Taylor & Francis.
