What Is Pre-Implantation Genetic Testing?
How can pre-implantation genetic testing help?
More than eight million children have been born through the process of IVF. IVF or in vitro fertilization involves ovarian stimulation to produce multiple eggs, which produces multiple embryos.
In the past, these embryos were evaluated by the embryologists looking at the embryo and assigning a grade to the embryo. Now with the use of the technology pre-implantation genetic testing for aneuploidy, the embryologist is able to evaluate the embryo by sending it to a laboratory and having the cells of the embryo tested.
After your egg donor goes through an egg retrieval the embryos are fertilized with sperm and these embryos are then grown to day five or day six. At that time the outer cells of the embryo, not the cells that ultimately make the baby, but the outer cells of the embryo are then biopsied and sent to a laboratory. Damage to the embryo is very unlikely during this transportation. This testing determines if the embryo has a normal amount of DNA and these are called euploid embryos. Transferring chromosomally normal embryos has a higher chance of implantation and a reduced risk of miscarriage. The goal of your fertility clinic is like yours, to help you take home a baby and the use of pre-implantation genetic testing for aneuploidy is one tool that can help make that happen.
