Used to genetically analyze embryos before they are inserted into the uterus.
Preimplantation Genetic Testing (PGT) is a technique used in in vitro fertilization treatments to genetically analyze embryos before they are inserted into the mother’s uterus. The purpose of this diagnosis is to genetically analyze the embryo to ensure that the baby will be born healthy.
How does the PGT/PGS work?
Preimplantation Genetic Testing (PGT) is a technique used in in vitro fertilization treatments to genetically analyze embryos before they are inserted into the mother’s uterus. The purpose of this diagnosis is to genetically analyze the embryo to ensure that the baby will be born healthy.
The technique involves removing cells from the embryo itself through a process called “embryo biopsy.” This is usually done when the embryo is five days old, in the so-called “blastocyst” stage. Learn what’s involved in each phase of Preimplantation Genetic Testing (PGT), what types exist and what each of them detect.
The different genetic tests of embryos are used to detect genetic and/or chromosomal abnormalities, increasing the chances that the baby will be born completely healthy.
It is especially recommended in elderly women, couples who have had miscarriages or in men who have chromosomal sperm disorders.
The PGT technique is normally performed when the embryos are 5 days old, though it is possible to do it on day 3 as well.
