For mothers, risks arising from multiple pregnancies range from those that are less serious to those that are life-threatening.
Pregnancy complications including hypertension, pre-eclampsia and gestational diabetes may require an early admission to hospital for the last weeks of pregnancy, and that the birth may have to be induced early. These complications, whilst they can occur in singleton pregnancies, are much more common in multiple pregnancies:
Maternal mortality associated with multiple births is 2.5 times greater than with singletons.
Many other countries have already successfully introduced a single embryo transfer policy – the multiple birth rate has plummeted while birth rates have remained largely unaffected.
