Preimplantation Genetic Testing (PGT)
Preimplantation Genetic Testing (PGT), is a technique used 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.
What is Preimplantation Genetic Testing (PGT)?
Preimplantation Genetic Testing (PGT) is a technique used 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 work?
How the Preimplantation Genetic Testing (PGT) is done
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 detects.
FAQ about PGT
Why is the preimplantation genetic testing (PGT) important?
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.
When is an embryo screening required?
It is especially recommended for elderly women, couples who have had miscarriages, or men who have chromosomal sperm disorders.
When is the embryo biopsy done?
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.
