Preimplantation genetic diagnosis (PGD)
Preimplantation genetic diagnosis or PGD is a vital study for couples who are known to be carriers of certain diseases that do not wish to pass on their offspring for their future health and well-being. This study helps couples to be certain that their children will not carry such ailments and thus facilitate their health and quality of life.
The Preimplantation Genetic Diagnosis Program aims to avoid transmitting to children genetic diseases that parents know to carry as hemophilia, cystic fibrosis, muscular dystrophy, among others, and also when it is known that there are nn eminent risk that the baby is born with a genetic syndrome such as Trisomy 21 (Down syndrome).
The presence of these diseases is analyzed in the DNA of the ovum or embryos to select those that comply with certain characteristics and discard those that have hereditary alterations.
In order to arrive at the Preimplantation medical diagnosis, in vitro fertilization done and the embryos formed in the laboratory are studied before transferring them to the mother’s uterus. During the study, one of the cells of the embryo is extracted and sent to a genetics laboratory and only the embryos whose cells are normal are transferred to the mother’s uterus.
To date babies born using this technique have not had adverse effects, but the long-term effects have not yet been assessed, and for this reason only this diagnosis should be performed when the benefits exceed the risks.
Inser is the pioneer fertility institute in this study throughout the country. To learn more about this study.
