Preimplantation Genetic Diagnosis (PGD)

 

Preimplantation Genetic Diagnosis (PGD)

Preimplantation Genetic Diagnosis (PGD) is a technique that allows a detailed analysis of the embryo before being transferred to the maternal uterus. This makes it possible to transfer embryos free of any hereditary disease. It is recommended as long as the patient has an optimal response to ovarian stimulation and the genetic disease under study is within the legal limits of techniques of assisted human reproduction.

The designed technique is only to be applied in case of the detection of serious hereditary diseases in an early appearance and in case there is no susceptible to postnatal curative treatment. This in order to select embryos that are not suitable for transfer. Likewise, this technique serves as well for the detection of other alterations that may compromise the viability of the embryo.

Once the first phases of the diagnosis have been carried out, such as embryo formation and embryo biopsy, we proceed with the different genetic analyses. It is at this point that the thorough study of hereditary diseases becomes fundamental.
