PGS and PGD are types of genetic testing that may be performed once an embryo is created through IVF. PGS can determine if an embryo has the correct number of chromosomes and the gender. PGD can determine if an embryo is affected or a carrier of a specific disease that has been discovered in either of the parents’ DNA.
A woman undergoes egg retrieval and her eggs are fertilized by an embryologist via IVF. On the 5th and 6th days after retrieval, the viable embryos will grow to a blastocyst stage. It is at this stage that the biopsy takes place, in house, removing 4-6 cells from the trophectoderm (which becomes the placenta). The embryos are cryopreserved (frozen) after the biopsy. The biopsied samples are then shipped to an outsourced company that performs the specific requested test and reports the results directly to DVIF&G. Once the results are reported, the ideal embryo will be chosen for a Frozen Embryo Transfer (FET).
