Preimplantatiol Genetic Testing

What is the Preimplantation Genetic Testing (PGT)?

PGT (Preimplantation Genetic Testing) is an embryo screening technique that allows the detection of genetic alterations in embryos before their transfer to the uterus. We speak of PGT-A when the study is done at the chromosomal level, and PGT-M when it is the study of a particular gene.

At Vida Fertility, our goal is to offer effective solutions to all fertility problems. We believe that PGT is one of the greatest advances in assisted reproduction and a fantastic way of achieving the desired ongoing pregnancy.

Preimplantation Genetic Testing

Who is it for?

Preimplantation genetic testing (PGT) can be performed on any treatment once we have viable embryos in the laboratory. However, there are particular cases for which our experts will indicate a PGT in order to increase the chances of successful results and improve the prognosis for an ongoing pregnancy:

  • Couples carrying genetic abnormalities.
  • Altered karyotype even for only one of the parents.
  • Women over 40 years of age, as there is a higher risk of having embryos with chromosomal abnormalities.
  • Patients with several previous failed in vitro fertilisation (IVF) cycles.
  • Patients with a history of repeated miscarriages.
  • Altered FISH in sperm.

What is the Preimplantation Genetic Testing procedure?

To perform a Preimplantation Genetic Testing, we need to extract several cells from the embryos at the blastocyst stage (Day 5-6 of embryo development). During this biopsy, about 8 cells are extracted in order to have enough genetic material and to be able to give a reliable result regarding the viability of the embryo.

After the biopsy, the embryos are vitrified (frozen) until receiving the test results, which takes about 3-4 weeks. With this test, we will be able to know with certainty whether the embryos will be able to result into an ongoing pregnancy, which considerably increase the life birth of a healthy baby.

Advantages of the PGT

The transfer of these viable embryos following genetic testing reduces the risk of miscarriage, implantation failure or transmission of genetic diseases.

Using this technique, we reduce the waiting time to achieve an ongoing pregnancy, which considerably lowers the stress for many patients facing the uncertainty of a viable pregnancy.

Preimplantation Genetic Testing in Spain

PGT or Preimplantation Genetic Testing is a technique that is authorised and easily accessible in Spain. Depending on each patient’s case, our gynaecologists and fertility specialists will be able to recommend the use of this technique to improve the embryo selection. PGT can be carried out as a preventive measure, or if there is a high risk of transmitting diseases to the child.
