Pre-implantation genetic diagnosis (PGD)
This is a series of procedures aiming to learn the genetic characteristics of the embryos obtained by means of in vitro fertilisation, in order to those which are suitable for their transfer to the uterus.
When is pre-implantation genetic diagnosis (PGD) used?
This technique can be useful in different situations:
- Patients infected with or carrying genetically transmittable diseases due to the alteration of a gene, known as monogenic diseases.
- Patients who are carriers of transmittable chromosome alterations.
- Patients with greater risk of genetic alterations in their gametes (oocytes and spermatozoa), which could determine the formation of genetically abnormal embryos.
