The long-term objective of this research is to improve patient understanding of the known and strongly suspected risks from treating infertility with assisted reproductive technologies such as in vitro fertilization (IVF). During IVF, when more embryos are transferred to the uterus, the risk of pregnancy with multiple fetuses increases. In addition, single infants conceived with IVF are at greater risk for low birth weight. This study will promote behaviors that may reduce these risks. One in 3 women who completes a pregnancy conceived with assisted reproductive technologies such as IVF delivers multiples, and these treatments produce over 12,000 multiple birth deliveries annually in the United States. This study will lead to a better understanding of the most effective ways to counsel IVF patients about the embryo transfer decision. This study will also help define how to prepare IVF patients to work most effectively with their prenatal care team to manage IVF-related obstetrical risks.
