Preimplantation Genetic Diagnosis:
Newlife Fertility Centre offers Preimplantation Genetic Diagnosis (PGD). This is genetic testing on embryos for chromosomal or genetic disorders thus allowing patients at risk for these disorders to have their embryos tested before transfer during in an in vitro fertilization (IVF) cycle.
PGD requires embryo biopsy and genetic analysis. Only the embryos that have the correct number of number of chromosomes and are free from abnormalities are considered for transfer in the IVF cycle. The genetic material of the embryo is not altered or harmed in any way during PGD Testing.
Who should consider PGD?
Newlife Fertility Centre does not recommend PGD for all its patients. Those who may be considered are:
- Women with recurrent miscarriage
- Chromosomal abnormality in a previous pregnancy
- Multiple IVF failures
- Patients who are carriers of a specific genetic condition (such as cystic fibrosis)
- Women over the age of 35
- Chromosomal aneuploidy (a variation in the number of chromosomes, ie an extra chromosome 21 in Down syndrome)
- Chromosomal rearrangements (inversions, translocations, deletions)
- Single gene disorders (ie cystic fibrosis, Huntington disease)
Preimplantation Genetic Diagnosis may not be available in all circumstances or for all genetic disorders.
