What is Pre-Implantation Genetic Screening (PGS)
Pre-Implantation Genetic Screening/Testing (PGS) , (also known as aneuploidy screening) involves checking the chromosomes of embryos created by in vitro fertilizations (IVF) or intracytoplasmic sperm injection (ICSI)for abnormalities. Embryos with abnormal chromosomes often end in miscarriage, a failed treatment cycle or the child may have a condition like Down’s Syndrome. During PGS, a single cell or a small number of cells is removed from the embryo. The DNA of these cells is then tested to see whether they have any chromosomal abnormalities. Only embryos without chromosomal abnormalities are placed back in the womb.
WHY PGS?
PGS is often recommended for Women over 35 years Old. As Maternal age Advances, a higher proportion of embryos are genetically abnormal. This higher Prevalence of Genetically abnormal embryos is the primary contributor to the decreased chance of successful pregnancy and Increased chance of Miscarriage in older Women. American Fertility Center Of Pakistan uses Advance PGS, with Best Qualified Doctors.
PGS May Considered when both partners are Carries for a specific Genetic Disorder. With Some other genetic Diseases, half of the embryos will be abnormal. Also, patients may have an increased risk for miscarriage because one of the partners carries a genetic rearrangement in their chromosomes, and genetic testing of embryos for these Couples may reduce the risk of miscarriage.
