The PGT-A method is an advanced technique used in IVF treatment to select an embryo with the normal number of chromosomes for transfer to the uterus. This selection is crucial as it increases the chances of successful implantation and development throughout pregnancy. Deviations from the normal number of chromosomes, known as aneuploidies, are common in older women and can result in failed IVF cycles or miscarriages. In addition to detecting Down syndrome, PGT-A can also identify other full chromosome genetic abnormalities such as Turner syndrome and Klinefelter syndrome with an accuracy rate of 98%. This method is beneficial for couples who have had multiple failed IVF attempts, older women, or those who have experienced repeated spontaneous abortions. PGT-A enables the identification of a single euploid embryo for transfer, making it a valuable tool in the journey towards a successful pregnancy and childbirth. PGT-A is a reliable method that minimizes the risk of aneuploidy and increases the chances of carrying a healthy child.
