Improve Your Chances of Conceiving a Healthy Baby with Preimplantation Genetic Diagnosis Testing
PGD diagnosis is done in conjunction with IVF or ICSI. Several days after fertilization has occurred, cells from the embryos can be harvested for genetic testing. This testing can allow us to detect any potential abnormalities and select the best embryo for implantation.
Many couples and women who choose to undergo in vitro fertilization (IVF) may be at risk for passing on heritable genetic disorders and can greatly benefit from a screening test that can identify affected embryos. Preimplantation genetic diagnosis (PGD), performed at our New Orleans-based locations, is an optional diagnostic test that can be performed during the IVF process to detect the presence of many genetic abnormalities.
If you or your partner has a family history of one or more heritable genetic disorders, PGD can provide you with the peace of mind you need. PGD is available to any of our patients who feel it may be beneficial. If you think that you could be at risk for passing on an inherited condition and would like more information about PGD testing, please contact our office to schedule a consultation.
The PGD Method
To understand PGD's role in infertility treatment, it helps to first understand how IVF works. After a semen sample is obtained, either from the male partner or a donor, it is combined with eggs outside the mother's body. PGD is performed after fertilization has taken place, but before implantation occurs (when the embryo is transferred to the mother's uterus). When the fertilized egg enters the cell division stage, one or two cells will be removed for DNA sequencing and molecular testing to determine if an abnormal gene is present. After the results have been obtained, healthy embryos that are not affected by the specific genetic disorder will be selected for transfer to the mother's body.
Indications & Candidacy for PGD
PGD is primarily used at The Fertility Institute for patients who are at risk for passing on inherited genetic disorders. Women over the age of 35, carriers of sex-linked disorders, and carriers of single gene defects may be good candidates for PGD.
PGD testing can indicate the presence of many conditions, including:
- Cystic Fibrosis
- Tay-Sachs Disease
- Beta Thalassemia
- Muscular Dystrophy
- Fragile X Syndrome
- Rett Syndrome
- Huntington's Disease
- Sickle Cell Anemia
- Down's Syndrome
As PGD technology continues to improve, it is becoming possible to identify the presence of a growing range of disorders. If you feel that you are at risk for passing on any conditions to your children, please talk to one of our specialists about the different options that we have available to our patients.
PGD is performed before the embryo is implanted in the uterus. This reduces the need to perform an amniocentesis later and allows the mother the opportunity to decide if she wishes to continue with the pregnancy before it is established. PGD also reduces the risks associated with multiple pregnancies because the test can identify healthy embryos for implantation, allowing our doctors to select just just a small number. This step also minimizes the risk of miscarriage.
