Limits to ART treatment

Permitted number of embryos IVF/ICSI

In IVF/ICSI the number of embryos that can be transferred per cycle is restricted by Belgian law.
The aim of this restriction to limit the number of multiple pregnancies as much as possible. This is because a multiple pregnancy implies an increased risk for mother and babies.
This limitation applies for all women having ART treatment in Belgium.
