REI Certification Standards Update

Watch this short video that offers an overview about this important REI certification standards update.



Starting with Academic Year 2022 - 2023, ABOG will be implementing important changes to the Reproductive Endocrinology and Infertility certification standards to advance training and respond to the contemporary practice of the subspecialty.


All updates are listed below, but you can download a printable PDF here: 2021 Apr New REI Standards 2022-2023 AY FINAL. Additionally, here is a table illustrating the comparison between previous and new standards: REI Table Standards Comparison


Email fellowship@abog.org with questions regarding any of the information provided here.


Change #1:

Renaming of the Clinical Experience standard to REI Core Clinical Experience to emphasize the importance of these topic areas and increase consistency among graduates’ knowledge, judgment, and skills in REI.


These expanded domains are outlined in the REI Blueprint and include:


  • Basic Science, Physiology, and Pathophysiology
  • Diagnostic Techniques and Interpretation for the Management of Reproductive Disorders
  • Evaluation, Diagnosis, and Management of Reproductive Endocrine Function and Disease
  • Female Fertility, Female Infertility, and PCOS
  • Male Infertility
  • Recurrent Pregnancy Loss
  • Assisted Reproductive Technology (ART) Techniques
  • Evaluation, Diagnosis, and Management of Complex Reproductive Disorders
  • Complex Reproductive Surgical Procedures
  • Genetics
  • Core Competencies and Cross Content

Change #2:

Increasing REI Core Clinical Experience from 12 months to 18 months.  This emphasizes the importance of clinical training and the experiences that comprise the core knowledge, judgment, and skills needed to practice REI.

The current REI standards broadly define core clinical experience to permit programs to have flexibility in designing an REI curriculum and scheduling of clinical experiences.  Programs should consider experience in genetics, male infertility, medical endocrinology, and pediatric endocrinology as parts of the REI core curriculum.


The Bulletin for REI also describes the core requirements of an REI curriculum as follows:


  • The candidate must gain diverse experience in the management of a wide variety of clinical problems affecting the development, function, and aging of the human reproductive system to include disorders of both men and women.  Specifically, the candidate must be trained in the following areas:


  • Medical disorders
  • Surgical techniques
  • Ultrasound
  • Laboratory procedures


Change #3:

Enhancing flexibility for programs and fellows to increase clinical experience using elective months of training.  In most programs, this may allow fellows to increase core clinical or elective clinical experiences by up to 6 months. The standard increases the opportunity for core clinical experiences from up to 18 months previously to up to 24 months. 

Fellows may choose to participate in more core clinical or elective clinical experiences that are related to REI and approved by the program and the fellow.

Change #4:
Enhancing flexibility for programs and fellows to integrate research experience during core clinical or elective clinical months of training.  The focus of any clinical experience months must be clinical care (for example, evaluation, diagnosis, management, and procedures).  However, ABOG does not restrict fellows from also participating in some research during these months.  The new standard preserves a minimum of 12 months focused on research and allows some longitudinal participation in research in clinical months experience.


Change #5:

Enhancing flexibility in scheduling research and elective research months.  The recommendation that a consecutive 12-month block of time be scheduled has been eliminated.  A continuous 12-month research experience may be optimal for some types of research. Distributing the research months experience over 36 months is also appropriate.


It may be beneficial for some fellows to choose up to six months of research electives.

Change #6

Aligning the certification standards and leave policy to assist fellows who need to take approved parental, caregiver, or medical leave during a fellowship.  In the 2019-2020 AY, ABOG increased the limits on approved leave that would not require an extension of a fellow’s training.  The yearly limit increased from 8 weeks to 12 weeksThe total leave limit increased from 15 weeks to 20 weeks.  Any leave more than either of these thresholds requires an extension of a fellowship. 

The new standards and policy permit a fellow to take up to 12 weeks in a year and up to 4 weeks in each of the other two years without the need to extend training.   Fellows are required to meet the minimum number of 18 clinical core and 12 research months (with satisfactory evaluations) to meet the new certification standard. The policy now focuses more on meeting the minimum standards for certification than setting limits on leave.
