SART has developed this predictor based on nearly 500,000 cycles of therapy to more than 320,000 women throughout the United States since 2006 ^1,2. This calculator is meant to help you understand your chances of having a live birth, based on your personal situation. The answers to the following questions influence the likelihood that the IVF treatment will be successful. Some of the answers you may know — like your height and weight. Other answers — such as the diagnosis of the cause of infertility — will depend on whether or not you have been seen by a physician, and may change during your course of treatment. The calculations from this Patient Predictor assume that you have not had prior IVF treatment.
