The three-year fellowship program in Reproductive Endocrinology and Infertility at the University of Pennsylvania is designed for candidates who are interested in a career in academic obstetrics and gynecology.

There is a significant research emphasis and 18 months are set aside for research free of clinical responsibilities. The remainder of the time is used for training in the clinical discipline of reproductive endocrinology and infertility, clinical research and/or continuation of bench research as appropriate.

There are two formal fellowship tracks:

  • physician-scientist track 18 – 24 months of bench research if the fellow is selected to be part of the NIH-funded T32 National Training Program in Reproductive Medicine
  • clinician-investigator track if the fellow is selected for formal training in clinical epidemiology and biostatistics leading to a Master of Science degree in Clinical Epidemiology (MSCE).  This program is also funded by an NIH T32 training grant in Reproductive Epidemiology.

Fellows who wish to obtain the qualifications to become IVF laboratory directors can enroll in the physician-scientist track and start their program with 18 months of gamete research, including specific training in the laboratory procedures utilized in a clinical IVF laboratory such as ICSI, microinjection and assisted hatching. This training component should prepare the fellow adequately for participation in the clinical IVF laboratory activities during the second half of the fellowship.

During the clinical training time there is a heavy practice component with emphasis on the surgical aspects of the discipline, assisted reproductive technologies and office diagnostic and therapeutic approaches. Through the Endocrine Sections of the Departments of Medicine and Pediatrics, supplemental clinical experience is available in adult as well as pediatric endocrinology. This is provided as elective rotations, although fellows are encouraged to participate. The use of the General Clinical Research Center of the Hospital complements the investigative aspects of the program. Supplementing the clinical facilities are the clinical research facilities of the Reproductive Research Unit of the Division and the laboratories of the Center for Research in Reproduction and Women’s Health. The reproductive genetics program of the Department of Ob/Gyn and the male infertility program are also involved in fellowship training.

Courses: Graduate courses in statistics and human genetics are required. Fellows in the clinician-investigator track who are part of the Penn MSCE program do not take the basic statistics course, but their curriculum includes multiple other biostatistics and quantitative courses designed to prepare them for an investigative career in reproductive medicine. A typical course curriculum for this track is outlined below:


EPID 502


Fundamentals of Medical Research II: Introduction to Biostatistics

This course is a series of lectures designed to provide an overview of the fundamental concepts of biostatistics.

EPID 510


Introductory Epidemiology

This course is a series of lectures and workshops, designed to teach basic principles of epidemiologic research design. The course provides an overview of the types of research questions that can be addressed by epidemiologic methods.

EPID 521


Statistical Methods for Epidemiologic Research

This seminar focuses on statistical methods for analyzing case-control, cross-sectional, and cohort studies, and clinical trials.

EPID 532


Database Management for Clinical Epidemiology

This course provides students with an introduction to the techniques of database management as they apply to clinical research.

EPID 542


Measurement of Health in Epidemiology

This course is a series of lectures and discussion sessions designed to introduce the student to the concepts of health measurement as applied to epidemiologic studies.

EPID 550


Clinical Economics and Clinical Deicision Making

This course focuses on the application of decision analysis and economic analysis to clinical and policy research.

EPID 560


Issues in Research Protocol Development

This is a seminar that focuses on major issues in research protocol development, including methodological issues regarding different research designs, development of research questions, and plans for analysis. Each student will present his or her research proposal for open discussion during one of the seminar sessions.

EPID 570


Critical Appraisal of the Medical Literature

This seminar focuses on techniques for critical appraisal of the medical literature.

EPID 610


Tutorial in Epidemiologic Research

This is a tutorial given by each student's advisor. Advisor and student meet regularly, usually weekly, throughout the first year of study. Topics include: discussion and review of epidemiologic concepts and principles, guided readings in the epidemiology of a specific health area, and the development of the research protocol. Credit for this course is awarded upon completion of a research project proposal, the one to be used to fulfill the MSCE thesis requirement, which must be approved by the student's advisor. Evaluation is based on the grade received for the proposal.

EPID 646


Reproductive Epidemiology

This is an advanced course that addresses epidemiological research issues as they apply to important clinical topics in obstetrics and gynecology and related clinical disciplines.

EPID 640


Advanced Topics in clinical Epidemiology

This course is designed to introduce students to advanced epidemiologic methods through a series of readings and discussions.

EPID 634


Clinical Trial Outcomes: Measurements, Analysis, and Interpretation

This course is intended to teach students the skills necessary to select and/or design appropriate outcomes for a clinical trial. Participating Faculty

Conferences and Seminars

Throughout the three years of training, fellows are required to attend didactic, research and clinical conferences, which include the ABOG Learning Objectives didactic conference, the Director’s Rounds and Journal Club, the (WWD)2 – Why We Do What We Do - conference, a divisional research conference, Ob/Gyn Grand Rounds and the CRRWH Seminar Series.

Evaluation of Fellows

Given the small number of fellows and close one to one interaction with faculty, performance feedback on clinical practice and on research occurs continuously. However, fellows are also evaluated formally by the faculty through an institutional computerized evaluation system for housestaff that automatically triggers faculty reviews of each trainee every six months.


The REI fellowship at the University of Pennsylvania provides both broad and in depth opportunities for training in all the clinical, educational and research aspects of the discipline.  Fellows continue to take advantage of this rich academic environment and, upon graduation, have excelled in either the clinical or research aspects of the field. Some have achieved both.


All faculty participate in the clinical training of fellows in the office, IVF and operating room.  Collectively, the participating faculty reflect expertise in Reproductive Medicine and Surgery, Clinical Epidemiology, Reproductive Biology, Genetics, Internal Medicine (andrology and endocrinology), Psychiatry, and Urology. The faculty participate in the fellows lecture series, journal clubs, research conferences and are avaialble to mentor fellow research projects.  Faculty primary research, interests are listed below.
