Reproductive Endocrinology and Infertility at Penn State College of Medicine

The mission of the Division of Reproductive Endocrinology and Infertility is to provide high-quality, humane and evidence-based care to couples and individuals who face barriers to fertility; and to use this approach to treat specific disorders of reproductive functioning and of the reproductive tract that effect the well-being and quality of life of effected individuals.

REI Division Intro Basic Content

Reproductive Endocrinology and Infertility (REI) is a field that addresses some of the most important and foundational issues that patients face in their lives. It is estimated that fewer than 25% of individuals with fertility challenges in the United States access care to have their needs met. In a state where the bulk of REI resources are concentrated in the far east and far west, we consider our program to be a vital part of the landscape in Pennsylvania and an important referral center for a wide catchment of patients who might otherwise be underserved.

The Division of Reproductive Endocrinology and Infertility at Penn State Health Milton S. Hershey Medical Center is a clinical practice in which patients reap the benefits of leading edge technologies and clinical care provided at a high level. Engaging novel, compassionate and streamlined approaches to the current care we administer is a step towards delivering on our clinical mission. As an academic REI division, we also have a track record of research and educational excellence fulfilling the tripartite mission of Penn State College of Medicine.

Education in Reproductive Endocrinology and Infertility

The division supports education in the principles of Reproductive Endocrinology and Infertility both within the department and beyond it. Members of division are active participants in grand rounds presentations, regionally and nationally, and members of our group routinely present educational content to departments whose trainees have overlapping interests with REI.

The division offers rotations both for undergraduate medical education and graduate medical education, and provides didactic education for trainees, students and advanced practice providers.

  • OBGYN Clerkship – Medical students in the core OBGYN clerkship can select to dedicate one week subspecialty ambulatory clinical time seeing patients in the division
  • OBGYN Elective – For advanced medical students who have completed the core OBGYN clerkship, an month-long elective in Reproductive Endocrinology and Embryology is available. This rotation provides exposure to the ambulatory, surgical, and laboratory aspects of the subspecialty and is often sought out by students applying for residency in Obstetrics and Gynecology
  • OBGYN Resident Rotations – Second and third year OBGYN residents complete a rotation in Reproductive Endocrinology and Infertility. The educational goals are mastery of the following: core concepts in the diagnosis and management of infertility, building differential diagnoses for reproductive endocrine disorders, pelvic sonography as pertains to comprehension and interpretation through hands on learning, principles in reproductive surgery
