An important decision that must be taken after discussion with the couple involves the number of embryos transferred to the uterus. We will inform you about the quality of your embryos before the embryo transfer.
According to national legislation the number of embryos transferred must not exceed three for women below the age of 40, and four for women over 40 years of age. However, this number can be further reduced in special cases (e.g. young woman with good quality embryos) without impairing the outcome. The factors that must be taken in consideration include embryo quality, age of the woman and medical history.
The choice of number of embryos transferred must meet a fine balance between the increasing pregnancy chances, which are usually enhanced by increasing the number of embryos, and at the same time reducing the chances of a multiple pregnancy, which is achieved by reducing the number of embryos.
Internationally, there is a tendency to reduce the number of embryos for transfer to one, as multiple pregnancy is not regarded as a successful achievement any more, but an undesirable side effect of IVF.
