Loss of ovule quality becomes especially relevant at 40 years of age, when a high proportion thereof, and therefore of the embryos available for transfer, may show chromosomal alterations.
Most of these abnormal embryos either will not produce a pregnancy or will end in pregnancy loss, but some may evolve producing children with serious malformations or mental retardation.
After 40 years of age, over 65% of embryos are altered.
Assisted reproduction laboratories have tools such as the time lapse system or the long-term culture, which allow selecting the embryos with the least chance of showing chromosomal anomalies. But apparently healthy embryos can show alterations that are not detectable by these systems, especially in older patients.
You can avoid failure or having a child with an alteration.
WHAT DO WE GET WITH PREIMPLANTATION GENETIC DIAGNOSIS?
By this state-of-the-art technology, we are capable of studying the genetics of all the embryos obtained by one in vitro fertilization cycle, and transfer only the embryos that we are sure are chromosomally normal.
The probability of achieving pregnancy with normal embryos selected by PGD is much higher, and similar to that obtained with donor’s ovules, even in patients over 40 years of age
With the Healthy Embryo program, based on PGD, you can avoid failure or having a child with an alteration.
In addition, being able to select chromosomally normal embryos enables us to be much more selective when it comes to transferring only one embryo, reducing the risk of twin pregnancy without reducing your chances of taking a healthy child home.
