The primary objective of this trial is to determine whether written educational materials plus brief education by telephone will help patients better understand and participate in the decision on how many embryos to transfer to the uterus during treatment of infertility with in vitro fertilization (IVF). The main study hypothesis is that women and men who receive the study's educational intervention will experience favorable changes in knowledge and beliefs about benefits, susceptibility and severity of multiple gestation that impact decisions about the number of embryos to transfer. Secondary objectives are to understand patient beliefs, knowledge and information preferences regarding other possible risks of IVF, to compare perception of IVF-related risks to familiar risks that are included in routine preconception health promotion, and during IVF, and to prepare couples to manage IVF-related obstetrical risks when they make the transition to prenatal care after becoming pregnant.
