What are my chances with ART?
While more models are coming soon, this model includes sequential transfers of fresh embryos only, no frozen transfers.
Welcome to the SART Patient Predictor. 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.

Multiple embryo transfer & Risk of multiple births

The goal of IVF treatment is a healthy singleton baby born at full-term gestation 3-5. On this page we are comparing the live birth rates and the chance of a multiple birth (twins, triplets, or quadruplets) when two embryos are transferred.
Why are pregnancies with twins, triplets and multiples high-risk?
Compared to singletons, the risk of infant death is more than 4-fold higher with twins and 13-fold higher with triplets.
