Polar Body Biopsy for Preimplantation Genetic Screening

People with infertility undergoing in vitro fertilization (IVF) can test the embryos using a method called preimplantation genetic screening (PGS) before they are implanted in the uterus to possibly increase their chances of having a successful pregnancy. One or more cells are removed from the embryo. The chromosomes inside the cells are then tested to identify normal or aneuploid embryo(s). The investigators propose to evaluate a test called micro array analysis on the chromosomes of the first polar body. This method tests part of the egg that would normally be lost and may help us choose the embryo most likely to become a healthy baby.
