UNDERSTAND THIS REPORT
This report is completely re-designed from the past. We did this to provide patients with outcomes that reflect changes in the way infertility is treated through IVF. In recent years, there has been increased emphasis on embryo cryopreservation, genetic testing, and single embryo transfer that was not adequately captured by the old reporting system. This report captures the treatment burden to the patient (the number of cycles) as well as the best outcome (delivery of a healthy child) by tracking outcomes over time for an individual, accounting for both fresh and frozen embryo transfers. We hope this will help you better understand the expected outcomes from Assisted Reproductive Technologies (ART). If you want to get a more personalized prognosis for your chances, please visit the SART patient predictor.
