Preimplantation Genetic Testing for Aneuploidies
(PGT-A)
Embryo implantation rate decreases with maternal age. Patients under 35 years old have a 31% chance of successful implantation, whereas patients over the age of 41 have only 6%. The dramatic decrease in implantation success correlates with chromosomal abnormality. For example, patients under 35 years old have a 54% aneuploidy rate, while patients between 41-42 have an 82% aneuploidy rate. PGT-A testing is performed to increase implantation rate by selecting chromosomally normal embryos.
