Pre-implantation Genetic Testing is an advanced genetic test designed to improve the implantation rate of in-vitro fertilization and give birth to a healthy child. Morphological appearance of an embryo cannot be used to evaluate chromosomal abnormalities. IVF outcomes are greatly influenced by a number of factors including
advancing woman's age,
number of embryos produced and
One of the main causes of the relatively low reproductive success rates seen in humans is numerical chromosome abnormalities (aneuploidy). The diagnostic methods such as preimplantation genetic testing-A (PGT-A, Aneuploidy for numerical chromosome abnormalities) and PGT-M (testing embryos for disease causing mutations) enable a detailed investigation of the chromosome content of human gametes and embryos towards a healthy birth outcome.
