About PGD Testing
To increase the possibility of a healthy pregnancy, the embryo, during its early stages, should be screened genetically to see whether or not there are abnormalities. This can be done through in-vitro fertilization (IVF) procedures. Determining chromosomal abnormalities before transferring the embryo, is done via a method called Preimplantation Genetic Diagnosis (PGD). This method is performed after the woman's egg has been fertilized in-vitro and prior to transferring the developing embryo back within the "mother's" womb. The embryo will naturally split into separate cells (known as bastomeres) after the stage of fertilization. At this point, each individual cell is essentially almost exactly the same. Meaning, testing one of these cells can tell a lot about the overall integrity of the embryo. With the use of different micro-manipulation methods, PGD is able to physically separate a cell from its embryo. The procedure usually removes a cell or two -- without damaging the embryo in any way. The cells that have been separated are then tested for abnormalities. Also, the "mother" and/or "parents" can opt to find out the gender of the embryo. Preimplantation Genetic Diagnosis is for women who are in their mid thirties and/or older. It is also highly recommended for women who have suffered recurrent miscarriage and/or IVF without pregnancy occurring. PGD is also very much recommended for people who want to choose their baby's gender and for people who are predisposed to genetic disorders which are gender related.
