We observed an increased risk of intrauterine growth retardation after egg donation abroad, which could essentially be explained by the association between advanced maternal age and multiple gestation. For other obstetric and perinatal complications, the differences between both groups were less important than expected, but very high in both groups, whether the egg donation was realized in France or abroad. The complications seem mainly due to the multiple gestations, justifying the transfer of a single embryo whenever possible.
