Preimplantation genetic screening (PGS)
PGS, Preimplantation genetic screening: this technique is used to identify genetic characteristics of the embryos, enabling us to select the most suitable ones for transfer and thus enhancing the chance of success.
PGD, Preimplantation genetic diagnosis: we use this technique in cases where we need to discard embryos affected by a specific inherited disease.
When is PGD necessary?
- Recommended in the following cases:
- Patients affected or being carries of an inherited gene mutation (monogenic disorder) who are at risk of passing it on to their offspring.
- Patients being carriers of chromosomal abnormalities that can be passed on to their offspring.
- Patients at a higher risk of having genetic alterations in their egg or sperm cells that could create genetically abnormal embryos.
