What does Preimplantation Genetic Diagnosis involve?
This technique allows us to perform a genetic screening of the embryos obtained during the In Vitro Fertilization process, thereby detecting possible chromosomal or genetic disorders before the embryos are transferred into the uterus. To perform a PGD, our biologists extract one of the 6-8 cells of the embryo and perform a biopsy. After the biopsy, the embryo is incubated in a culture medium which provides the adequate environmental conditions for its development until it is transferred into the uterus.
The cell obtained during the biopsy is genetically screened in order to check if the embryo carries a chromosomal or genetic disease. The remaining cells of the embryo are genetically identical to the analysed cell and continue to develop in the incubator. The day after the removal or the embryonic cell, we can know which embryos have no genetic disorders and can be transferred into the patient’s uterus. |
