Everything You Need to Know About PGT-A Testing and IVF

IVF, or in-vitro fertilization, is a fertility treatment that involves extracting eggs and sperm, combining them in a lab dish, and transferring the resulting embryos to the uterus. IVF has helped many couples achieve their dream of having a baby. However, it is not always successful. One of the factors that can affect the success rate of IVF is the quality of the embryos. This is where PGT testing for IVF comes in.

What is PGT-A testing?

Preimplantation genetic testing for aneuploidy, is a procedure that checks the number of chromosomes in an embryo. An embryo with an abnormal number of chromosomes is called aneuploid. Aneuploidy is a common cause of miscarriage and failed IVF cycles. PGT-A testing can identify aneuploid embryos, allowing the selection of the best-quality embryos for transfer.

How is PGT-A testing done?

PGT-A testing is done on embryos that have been created through IVF. During IVF, multiple eggs are retrieved from the woman’s ovaries and fertilized with sperm in a lab dish. The resulting embryos are then cultured for a few days until they reach the blastocyst stage. At this point, a few cells are removed from each embryo and sent for PGT-A testing. The cells are analyzed to determine the number of chromosomes present. Once the results are available, the embryos can be ranked based on their chromosomal status.

Who can benefit from PGT-A testing?

PGT-A testing can benefit many couples undergoing IVF. It is particularly useful for women who are of advanced maternal age, those who have a history of recurrent pregnancy loss, and those who have experienced failed IVF cycles in the past. PGT-A testing can also be used in cases where there is a known genetic condition in the family, such as a chromosomal translocation, that increases the risk of having aneuploid embryos.


What are the advantages of PGT-A testing?

PGT-A testing can increase the chances of a successful IVF cycle. By identifying the best-quality embryos, PGT-A testing can improve the chances of pregnancy and reduce the risk of miscarriage. PGT-A testing can also reduce the number of embryos that need to be transferred, which can lower the risk of multiple pregnancies.
