Effect of the mode of assisted reproductive technology conception on obstetric outcomes for survivors of the vanishing twin syndrome

Survivors of the "vanishing" twin syndrome, which occurred in dichorionic twins only, and singletons that began as singletons, had similar mean gestational duration and birth weights, as well as similar frequencies of maternal and neonatal complications. This similarity persisted when conventional IVF and IVF plus ICSI cases were separately evaluated.
