Recent findings The field of REI continues to rapidly evolve largely due to the tremendous advances within the assisted reproductive technologies (ARTs). Alongside this evolution, there is a lessening emphasis on graduates being proficient in all aspects of REI. Ongoing revisions to the REI fellowship structure reflect these changes in technology and contemporary practice patterns. Summary REI is a rapidly evolving field and fellowship training is continually adapting to meet the changing landscape of our field. Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.
