What is PGD (Pre Implantation Genetic Diagnosis) or Preimplantation Genetic Testing?

PGD (Preimplantation Genetic Diagnosis), is a process that allows genetic testing of an embryo prior to implantation and before pregnancy occurs. The procedure coincides with In-Vitro Fertilization (IVF) and uses only embryos analyzed as being free of a specific genetic disorder to be transferred for pregnancy.
PGD is broadly used to refer to any testing performed on an embryo prior to it being transferred to the uterus. However, there is a difference in the terms PGD and PGS.
PGD, Preimplantation Genetic Diagnosis, is a test looking for a specific genetic condition (like cystic fibrosis, sickle cell disease, muscular dystrophy) prior to transfer
PGS, Preimplantation Genetic Screening, is testing for overall chromosomal normalcy in embryos. PGS is not looking for a specific disease diagnosis – it is screening the embryo for normal chromosome numbers.
By testing the chromosomes of the embryos available for transfer, fertility clinics can discard embryos with abnormal chromosomal arrangements and pick the embryo(s) for transfer from those with normal chromosomes.
If you answer Yes to any of these questions, PGD could be helpful for you:
            Are you a woman over the age of 35?
            Have you suffered from several miscarriages?
            Have you had a previous pregnancy with a chromosome abnormality?
            Has a past IVF cycle been unsuccessful for you?
            Does low sperm count play a role in your difficulty to conceive?
            Are you aware of any family history of genetic diseases? For example: cystic fibrosis, muscular dystrophy or Huntington disease
            Do you want to choose the gender of your child?
