Preimplantation Genetic Testing for Aneuploidies (PGT-A)
What Is PGT-A And Why Should You Consider Utilizing It With Your IVF Cycle?
Preimplantation Genetic Testing for Aneuploidies (PGT-A) is a genetic test that is proven to increase your chances of a successful pregnancy. In addition, it contributes to having a healthy and happy pregnancy. Preimplantation genetic screening was first introduced for use with IVF in the United States in the mid 1990s. PGT-A allows for the determination between normal (euploid) embryos from abnormal (aneuploid) ones. PGT-A testing evaluates all 46 chromosomes, the 44 non-sex chromosomes plus X and Y. When an embryo is tested using PGT-A, the test identifies whether or not the embryo contains: the correct amount of genetic material, the correct number of chromosomes and the correct copies of them, too.
Who Can Benefit from PGT-A?
On-going research has shown that about 50% of embryos tested with PGT-A are aneuploid and this rate significantly increases with one’s age; especially, after the age of 35. As a result, PGT-A is appropriate for nearly ALL IVF patients. Research also has shown IVF pregnancy rates increase by more than 20% in patients who’ve utilized PGT-A versus those that have not.
