If you are considering in vitro fertilization to help you realize your dream of having a family, there are two separate methods of preimplantation testing for embryos to be aware of. Both provide helpful information about the embryos and may assist in planning for your transfer. Risks of a specific genetic disorder in the embryos can be revealed through preimplantation genetic diagnosis. Preimplantation genetic screening on the other hand can be used to look at the chromosomal makeup of the embryos.
Preimplantation Genetic Diagnosis (PGD)
If one or more partners are known carriers for genetic disorders like cystic fibrosis, fragile X syndrome or myotonic muscular dystrophy PGD may be recommended. When the embryos have grown for 5 days and are in the blastocyst stage, a biopsy of the embryo is performed an is sent to an outside lab specialized to evaluate the embryo(s). The testing is limited to that known genetic disorder but does provide information on which embryo(s) are affected by that disorder. In the meantime, the embryo(s) are frozen via cryopreservation until the results from the biopsy are returned. Embryos chosen to transfer can be utilized in a frozen embryo transfer (FET) the following month.
Preimplantation Genetic Screening
The presence of abnormal or unbalanced chromosome numbers can cause complications such as a heightened risk of miscarriage, implantation failure and Down Syndrome. Some embryos are not compatible with life and would not result in a pregnancy. Risks can be identified through preimplantation embryo screening.
