What is it?
Pre-implantation Genetic Diagnosis (PGD) makes it possible to identify the presence of genetic diseases or chromosomal alterations of oocytes and/or embryos obtained during an in vitro fertilisation cycle before they are transferred into the female partner’s uterus.
The procedure consists in analysing the polar bodies, blastocele fluid or a sample of cells from the embryo in order to transfer only embryos seen to be normal during analysis.
In addition to the normal IVF-ET/ICSI cycle procedure to be undergone by the couple, PGD may also require a preliminary biomolecular phase for the preparation of the laboratory material (known as probes), essential for the subsequent disease analysis performed on the oocytes and embryos.
The technique requires sophisticated technology, specialised staff and a dedicated special organisation and it is only recommended for couples with a high reproductive risk.
