Preimplantation Genetic Testing (PGT) is an advanced genetic screening technique performed during an IVF cycle to assess the health of embryos before implantation. A few cells are gently removed from the embryo at the blastocyst stage and analyzed for genetic or chromosomal abnormalities. This process helps identify embryos with the highest potential for successful implantation, healthy fetal development, and reduced risk of miscarriage or inherited disorders.
PGT is classified into three main types based on clinical need. PGT-A (Aneuploidy Testing) screens embryos for abnormal chromosome numbers, a common cause of failed implantation and pregnancy loss. PGT-M (Monogenic Disorder Testing) is used when one or both partners are carriers of a known inherited genetic condition, helping prevent transmission of specific genetic diseases. PGT-SR (Structural Rearrangement Testing) is recommended for individuals with chromosomal rearrangements such as translocations or inversions, which may affect embryo viability.
PGT improves IVF success rates by selecting genetically normal embryos, increasing implantation chances and reducing miscarriage risk. It helps minimize repeated IVF cycles, saving time, emotional stress, and financial burden. PGT supports safer single-embryo transfer, lowering the risk of multiple pregnancies while maintaining high pregnancy outcomes. Couples also gain reassurance and confidence knowing their embryos have been thoroughly evaluated for genetic health.
Preimplantation Genetic Testing (PGT) is chosen to enhance the safety, accuracy, and success of IVF treatment by ensuring that only genetically healthy embryos are transferred. Many embryos may appear normal in shape but still carry chromosomal or genetic abnormalities that can lead to implantation failure, miscarriage, or inherited disorders. PGT helps identify these issues early, significantly improving implantation rates and reducing the emotional and physical burden of repeated IVF cycles. It is especially beneficial for couples with recurrent pregnancy loss, repeated IVF failures, advanced maternal age, or a family history of genetic diseases. By enabling the selection of chromosomally normal embryos, PGT lowers the risk of miscarriage and supports healthier pregnancy outcomes. It also allows safer single-embryo transfer, minimizing the chances of multiple pregnancies while maintaining high success rates. PGT provides clarity, confidence, and informed decision-making, helping couples move forward in their fertility journey with reassurance, realistic expectations, and a greater likelihood of achieving a healthy pregnancy and
