While there are many benefits to choosing Preimplantation Genetic Testing, let's break down four of the main benefits and why they're important here. Each of these has a clear upside, but depending on your health history or genetic concerns, certain benefits may stand out to you personally.
Overall, PGT is considered safe with no known increase in associated risk of birth defects or genetic disorders. The biopsied cells are removed from the outer ridge of the embryo that ultimately becomes the placenta, not the fetus, which limits the risks.
Also, these same cells can be used for PGT-A, PGT-M, and PTG-SR. That said, there is always a slight chance that removing the cells from the trophectoderm could damage or disrupt the embryo. The risk of this is said to be less than 1%.
