Preimplantation Genetic Testing for Aneuploidy (PGT-A) involves analyzing cells from a developing embryo created through in vitro fertilization (IVF) to determine if they have the correct number of chromosomes. This process aims to identify embryos with a normal chromosome complement, increasing the chances of successful implantation and a healthy pregnancy. The timeline associated with this chromosomal screening is a crucial factor for individuals undergoing IVF.
This genetic assessment offers significant advantages, including a reduced risk of miscarriage and a higher probability of a successful live birth, particularly for women of advanced maternal age or those with a history of recurrent pregnancy loss. Historically, such testing methods have improved significantly, offering more precise results and enabling informed decisions during the IVF journey, improving outcomes for those at risk.
