Interpreting Results of Genetic Testing on Embryos

When going through fertility treatment and in vitro fertilization (IVF) you will likely be given the option of genetic testing of the embryos to rule out genetic disorders, increase the chance of pregnancy, and reduce the risk of miscarriage. What do you need to know about interpreting these test results? Host Dawn Davenport, Executive Director of Creating a Family, the national infertility & adoption education and support nonprofit, interviews Dr. Cary Dicken, a Board Certified reproductive endocrinologist with Sher Fertility Institute of New York; and Amy Jordan, a board certified Genetic Counselor with CooperGenomics, and former chair of the Genetic Counseling Special Interest Group for the American Society for Reproductive Medicine.
