Training
Fellowship in Pediatric and Adolescent Gynecology (PAG)
The NICHD Fellowship in PAG is a non-Accreditation Council for Graduate Medical Education (ACGME)-accredited, 2-year fellowship program comprising faculty from NICHD and Children’s National Hospital (CNH). The fellowship is housed within NICHD at NIH, and the care of patients will take place at NIH and CNH .
Fellowship Mission
- Ensure all graduates possess the knowledge, skills, and professional attributes essential to provide outstanding PAG clinical care.
- Grow the next generation of PAG leaders and researchers.
General Information
The goal of this fellowship is to train graduates of an ACGME-accredited obstetrics and gynecology residency in the gynecologic care of patients between birth and age 21. The fellow will learn the diagnosis and management of common problems in pediatric gynecology as well as uncommon and more complex conditions, such as congenital reproductive anomalies and anorectal malformations, variations in sex characteristics (VSC), pediatric and adolescent pelvic masses and gynecologic malignancies, gynecologic disorders in medically complicated children, reproductive endocrinopathies, fertility preservation, sexual abuse, and vulvar conditions.
The fellows also will receive extensive surgical training and will perform complex gynecologic surgeries in children of all ages, including those related to pelvic masses (benign and malignant) and congenital anomalies of the reproductive system, including those with anorectal malformations, in collaboration with the colorectal team. In addition, fellows will receive training and support for research development. Our goal is that graduates will pursue careers that advance the field of PAG in all areas, including research, education, and patient care.
Our fellows will interact with fellows in reproductive endocrinology and infertility and pediatric endocrinology within NICHD as well as pediatric surgery, pediatric urology, and adolescent medicine fellows at CNH. Opportunities for collaboration with Women and Infant Services fellows at MedStar Washington Hospital Center are also available. This interaction nurtures a rich academic environment that promotes excellence in clinical care, education, and research. Furthermore, our location is in the nation’s capital, which houses the American College of Obstetrics and Gynecology.
The Fellowship in PAG at NIH and CNH will entail 70% clinical work and 30% research, with rotational blocks dedicated to fellow research time. During clinical time at CNH, fellows will participate in general pediatric gynecology clinics as well as a variety of specialty clinics staffed by the PAG team. Fellows also will participate in emergency surgeries and those generated by the general and specialty clinics. Multidisciplinary clinics include those that care for patients with fertility preservation and survivorship, heavy menstrual bleeding, variations in sex characteristics, colorectal anomalies, Turner syndrome, anorectal malformations, complex endocrinology conditions, and rheumatologic conditions. In addition, fellows will have opportunities to rotate with providers specializing in eating disorders and child abuse. At the NIH, fellows will participate in the consult service and assist in the gynecologic care and research for studies in McCune-Albright, congenital adrenal hyperplasia, Turner syndrome, Mullerian agenesis (MRKH), fertility preservation and androgen insensitivity syndrome (AIS).
