It's a Good Egg (or Embryo)
Aneuploidy — an abnormal number of chromosomes — in embryos is one of the reasons why many in vitro fertilization cycles (IVF) fail. Either the embryo doesn't implant, or there is a miscarriage. As a woman ages, the more likely she is to have eggs with aneuploidy, which is why miscarriages are more likely as a woman gets older.
Many fertility clinics are using preimplantation genetic screening (PGS) techniques that test all 24 chromosomes in conjunction with in vitro fertilization (IVF) in order to help older women or those who have experienced recurrent miscarriage to increase their chances of having a successful pregnancy and healthy baby. This kind of aneuploidy screening helps fertility doctors determine which embryos have a full set of chromosomes and which ones have an abnormal set so they can select the embryos that have the highest chances of implantation in the uterus.
In addition, there are even more exciting advances on the horizon with researchers looking at ways to test a woman's eggs for aneuploidy before they are fertilized in vitro; and a new genetic test (still in clinical trial phase) that offers fertility patients the chance to test their embryos with reduced time and financial strain than existing screening techniques.
Try not to get discouraged if you have had failed IVF or recurrent miscarriage. Every day, there are new developments that may be able to help.
