Seeing double? In Singapore there is a 15- to
20-percent chance of conceiving two or
more babies with IVF (in vitro fertilisation)
treatment. Dr Kelly Loi gives us the
lowdown on the link between multiple
births and fertility treatment.
Does IVF treatment increase a woman’s chance of having a multiple pregnancy?
The chance increases the more embryos are transferred. In Singapore the number is restricted to two or three, but a two-embryo transfer policy is now common in many countries. The restrictionworks to prevent high-order pregnancies (e.g., triplets and quadruplets), which have a higher risk of complications including premature labour, neurological problems and prolonged neo-natal intensive care. In Sweden where 70 percent of its IVF cases involve the transfer of just one embryo, they have the lowest rate of multiple births.
