Preimplantation Genetic Testing (PGT)

Knowing if an embryo has a genetic or chromosomal alteration is already possible.

With Preimplantation Genetic Testing (PGT) we can study the genetic or chromosomal constitution of an embryo before transferring it to the uterus to detect if it has any alteration.

The PGT, consists of biopsy some cells of the embryo when it reaches its fifth day of embryonic culture, in the Blastocyst state. Cells of the so-called Trophectoderm are extracted. These cells are the ones that form the implant structures and the placenta. Cells of the so-called Internal Cellular Mass, which are the ones that form the fetus, are not extracted. With this cell we can make different variants of the PGT:

PGT-A: Refers to the PGT of Aneuploidies. Aneuploidies are alterations that affect the number of chromosomes or their structure. They can be complete or partial.
PGT-M: Refers to the study of diseases caused by mutations in a gene. It is a technique to prevent the transmission of monogenic diseases (affecting a single gene) such as cystic fibrosis or haemophilia.

When is it advisable to perform a preimplantation genetic diagnosis?

Women over 37 years
History of two or more misscarriages
Couples with altered karyotypes
Men with chromosomal abnormalities in sperm detected by sperm FISH study
People with genetic (non-chromosomal) diseases that can be transmitted to offspring

It must be taken into account that preimplantation genetic testing (PGT) is a partial study of the genetic material of several cells, so we can only provide information on what is studied in each case, not on the entire embryo.
