Preimplantation Genetic test is a specialized procedure that screens embryos for chromosomal aberrations or monogenic hereditary diseases before they are transferred into the uterus. This procedure is an essential part of in vitro fertilization (IVF) and serves three main clinical purposes: preimplantation genetic testing for aneuploidy (PGT-A), for monogenic disorders (PGT-M), and for chromosomal structural rearrangements (PGT-SR). This is crucial as studies have shown that aneuploidies, or numerical chromosomal abnormalities, are a leading cause of infertility. The ultimate goal of preimplantation genetic test is to select healthy embryos for transfer, increasing the chances of a successful pregnancy. This testing requires an embryo biopsy performed by our expert embryology team, which is a safe but invasive procedure. The embryo is typically biopsied on day 5 or 6 of development by removing a few cells from the trophectoderm. These cells are then analyzed for abnormalities, and the embryo is cryopreserved until the results are available. Preimplantation genetic testing provides couples the opportunity to have a healthy child and reduces the risk of passing on genetic disorders to future generations.
