Preimplantation genetic testing, also known as PGT, evaluates the genetic health of an embryo prior to a transfer to the uterus, where it can implant and grow during a pregnancy. PGT is an option that some patients may want to take, particularly if they’d like to prevent any known genetic disease from continuing down the family line or if they have experienced repeated pregnancy losses due to egg quality.
The technology and science behind genetic testing for embryos has grown in leaps and bounds over the years, with specialists now able to be incredibly precise when performing a detailed chromosome analysis. A better understanding of the genetic health of embryos allows your care team to select the healthiest possible embryo to increase your chances of success.
Join Dr. Juan Alvarez as he discusses everything you should know about preimplantation genetic testing. We’ll cover the basic info and terms you should know, the different types of PGT, the diagnoses that PGT can help with, the process from beginning to end, and helpful info that can guide you during treatment.
