Preimplantation Genetic Testing (PGT)
The heartbreak of a previous lost pregnancy or the worry that you may be passing on an inherited disease can put added stress on a couple seeking fertility treatments. For these couples, preimplantation genetic testing (PGT) may improve chances for a successful pregnancy and bring some peace of mind, especially in women 38 years of age and older.
What is PGT?
PGT is the process of screening cells from embryos for genetic diseases and chromosomal disorders. This test is done in conjunction with in-vitro fertilization (IVF) before the embryo transfer and pregnancy is established.
Various PGT tests can identify embryos with an abnormal number of chromosomes, or structural rearrangements that could prevent successful outcomes. PGT can also identify the presence of more than 4,000 single-gene disorders, including cystic fibrosis, spinal muscular atrophy, and fragile X in couples who are found to be carriers of one of these genetic mutations. Testing enables our physicians to identify the embryos most likely to result in a healthy baby for transfer.
PGT for Sex Selection
PGT technology can also be used to determine the sex of the embryo prior to the transfer into the uterus. Sex selection is offered to couples interested in family balancing who already have at least one child.
What Are My Chances for a Successful Pregnancy With PGT?
Many factors go into a successful pregnancy, including age, the number and quality of your embryos, the results of biopsies, and other fertility-related factors. While pregnancy success cannot be guaranteed, a 60%-70% success rate can be expected with PGT.
