Reproductive Endocrinology and Infertility
Reproductive Endocrinology and Infertility (REI) is a subspecialty within Obstetrics and Gynecology which requires an additional 3 year subspecialty fellowship. During that period of time, trainees focus on mastering the diagnosis and treatment of endocrine disorders related to the human reproductive system. Additionally, REIs focus on the diagnosis and treatment of infertility utilizing an array of assisted reproductive technologies.
REI physicians are referral sources for disorders of steroidogenesis, sexual development, puberty, menstruation, hirsutism/PCOS, menopause, hormone replacement therapy, thyroid/adrenal function and reproduction, recurrent pregnancy loss, and male/female fertility, among other things. Many also specialize in the genetics of reproduction and inherited disorders, laboratory science, and molecular biology.
REI Educational Resources for OB/GYN Residents
Understanding reproductive biology is imperative for all OB/GYNs. A firm grasp of the fundamentals for many topics under the purview of REIs will ensure a thoughtful approach to many disorders in general gynecology and in the initial work-up and treatment of the infertile couple. The following may serve as educational resources during residency:
- Reproductive Endocrinology and Infertility PROLOG. After studying this unit in the PROLOG series, you should be able to establish differential diagnoses and screen with appropriate diagnostic tests for specific conditions in gynecology and infertility.
- ASRM airLearning. This resource includes lectures (approximately 1 hour) on topics including Pediatric Gynecology, Precocious Puberty, Developmental Disorders, Delayed Puberty, Amenorrhea, Hirsutism, Infertility Evaluation, PCOS, and many more!
- Endotext.org is another excellent source for information about reproductive, medical and pediatric endocrinology. Many of the available chapters have been written by leaders in the field of REI.
Fellowship Training in REI
Whether you are seeking a career in basic sciences, clinical research, or the practice of Reproductive Endocrinology and Infertility, you will find a fellowship to meet your particular needs and interests. All fellowships are standardized to include 18 months of clinical education and 18 months of research education and experience.
