Preimplantation Genetic Diagnosis (PGD)

Preimplantation Genetic Diagnosis (PGD)

A collection of tests that are carried out on the embryo before it is transferred to the mother’s uterus to ensure that it does not suffer from a specific genetic disorder.

We study the DNA of the embryos and select those that are free from chromosomal anomalies and/or genetic mutations.

Indications

To prevent the transmission of a specific genetic disease such as cystic fibrosis, neurofibromatosis, fragile X syndrome or haemophilia, amongst others, from parents to their children.
Structural alterations in the karyotype of one of the parents that can compromise the pregnancy or the health of the future baby.
A history of numerical chromosomal abnormalities in previous pregnancies.
Advanced maternal age. The older we are, the higher the risk of chromosomal abnormalities (e.g. Down’s syndrome).
Implantation failures in IVF cycles; the percentage of affected embryos can be up to 70%.
Altered FISH in sperm DNA. Men with fertility problems can have an increased number of numerical chromosomal abnormalities in their sperm.

Selecting unaffected embryos allows us to increase the possibilities of a pregnancy and reduce the risk of spontaneous miscarriage and therapeutic abortion.
