Preimplantation genetic screening (PGS) is a procedure used to check the chromosomes of an embryo created by in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) for abnormalities. PGS does not check for specific genetic diagnoses, but rather screens for chromosomal abnormalities.
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 for potential implantation.
Women who are older are more likely to have eggs with the wrong number of chromosomes, which is believed to be the primary reason why older women may experience difficulty conceiving or may have a higher risk of having a baby with Down syndrome. However, PGS involves taking a biopsy, which can sometimes cause damage to the embryo and prevent it from developing once it has been transferred into the womb.
PGS may be recommended if a patient has a family history of chromosomal problems, if the sperm is at risk of carrying an abnormal chromosome, or if the patient has experienced several miscarriages or failed IVF attempts without explanation.
