Obstetric and neonatal outcomes of IVF versus spontaneously conceived dichorionic twins

ObjectiveTo evaluate the obstetric and neonatal outcomes of dichorionic twin (DD) pregnancies after IVF in comparison to spontaneous conception (SC).DesignRetrospective cohort study.SettingWomen Hospital – Hamad Medical Corporation, Doha, Qatar.Material and methodsAll cases of DD twin pregnancies during the period from January 2002 to December 2011 were included. Demographic and clinical data, obstetric and neonatal outcomes of DD twin pregnancies after IVF and SC were compared.Main outcome measuresMaternal and neonatal outcome.Results145 (80%) and 175 (79.6%) DD twins after IVF and SC were included respectively. IVF was not associated with more obstetric complications than SC group. Six neonatal deaths occurred in both groups. The rate of CS was slightly but not significantly higher in IVF pregnancies (78% versus 68%). In IVF and SC there were 15 malformed fetuses in each group.ConclusionsThe present study reported comparable obstetric and neonatal outcomes of DD twin pregnancies after IVF in comparison to SC provided that the same management criteria are applied to both types of twin pregnancy.
