In Vitro Fertilisation failures
Why did the IVF fail?
In some cases after In Vitro Fertilisation cycles, pregnancy is not achieved.
When the womb is well prepared for receiving the embryo the cause is usually embryonic since most human embryos do not have the correct chromosome dotation to be able to develop.
In an in-vitro fertilisation cycle, better quality embryos are selected to be transferred to the woman’s womb. But the morphological evaluation of the embryo does not make it possible to distinguish chromosomal anomaly carrying embryos.
In these cases it is necessary to study the embryos to be able to identify those that are chromosomally normal. This is carried out by an In Vitro Fertilisation cycle with Preimplantation Genetic Diagnosis.
