Gynecologic Health and Disease Branch (GHDB)

Tissue under MicroscopeOverview/Mission

GHDB aims to improve women’s reproductive health by guiding and supporting gynecologic research and career development programs with the vision of a future in which women lead lives free of the effects of gynecologic disorders. The branch portfolio includes studies of healthy functioning endometrium and menstruation, as well as gynecologic disorders including endometriosis, adenomyosis, fibroids, and polycystic ovary syndrome. In addition to abnormal vaginal bleeding and pain throughout the reproductive lifespan, these disorders may affect fertility potential, delay pregnancy, and contribute to maternal morbidity and adverse pregnancy outcomes.

The branch has an interest in pelvic organ prolapse as well as urinary and fecal incontinence related to pelvic floor dysfunction. Obstetric fistula and female genital cutting, which affect international and U.S. immigrant communities, are also areas of interest.

We are interested in applications that align with the following research priorities. For more information about NICHD’s research themes, cross-cutting topics, and aspirational goals, visit the plan’s Scientific Research Themes and Objectives.

Non-Invasive Diagnostic and Screening Tools

Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health
Strategic Plan Cross-Cutting Topics: Disease Prevention, Health Disparities
Strategic Plan Aspirational Goal: Accelerate efforts to definitively diagnose, prevent, and treat endometriosis

Gap: Emerging imaging techniques and insights into the biology of gynecologic tissues provide opportunities for developing innovative approaches to the early detection and clinical monitoring of gynecologic diseases. These tools are likely to play a pivotal role in pursuing natural history studies, better understanding phenotypic variability, reducing the interval between development of symptoms and diagnosis, and determining the safety and efficacy of novel treatments.

Priority: Research that develops and/or applies novel imaging methods and biomarkers to gynecologic disorders, especially endometriosis, adenomyosis, and fibroids. These tests should be non-invasive, rapid, inexpensive, and widely available to medically underserved populations. Of interest are studies that harness the techniques of machine learning and artificial intelligence.

‘Omics in Gynecologic Disorders

Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health
Strategic Plan Cross-Cutting Topic: Health Disparities

Gap: 'Omics approaches have the powerful ability to substantially improve our understanding of the etiology and pathophysiology of gynecologic conditions, as well as the ability to develop new, patient-specific treatments.

Priority: Multidisciplinary investigation of the genome, epigenome, and/or transcriptome as they affect healthy endometrium, menstruation, or the development, progression, and/or treatment response in gynecologic conditions. Examination of the interaction between environmental factors and genetic and/or epigenetic markers are of interest, especially for health disparity populations.

Development of Novel Model Systems to Address Health and Disease

Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health
Strategic Plan Cross-Cutting Topics: Disease Prevention, Health Disparities

Gap: The study of gynecologic disorders is compromised by a lack of model systems that appropriately recapitulate aspects of the conditions. 

Priority: Innovative in vitro, in vivo, ex vivo, and in silico model systems to study healthy endometrium, menstruation, and gynecologic conditions, including whole animal models, cell lines, organoid culture, and tissue-on-a-chip studies, among other techniques.

Stem/Progenitor Cells and Regenerative Techniques in Gynecologic Health and Disease

Strategic Plan Theme 1: Understanding the Molecular, Cellular, and Structural Basis of Development
Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health

Gap: Emerging data suggest a role for stem cells in normal endometrial function, abnormal menstrual bleeding, and the pathophysiology of specific gynecologic disease states, especially endometriosis, adenomyosis, and fibroids. Modulation of stem cell activity shows promise as an effective therapy in other disorders, but it has not been adequately explored for gynecologic conditions.

Priority: Research investigating the role of endogenous stem cells in normal endometrial function and in the etiology and pathophysiology of gynecologic disorders. Of interest is the application of regenerative techniques to the treatment of pelvic floor disorders.

Therapeutics and Devices for Gynecologic Conditions

Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health
Strategic Plan Theme 5: Advancing Safe and Effective Therapeutics and Devices for Pregnant and Lactating Women, Children, and People with Disabilities
Strategic Plan Aspirational Goal: Accelerate efforts to definitively diagnose, prevent, and treat endometriosis

Gap: Most treatments for gynecologic disorders are based upon manipulation of the steroid hormone milieu. There is a need for medical and surgical therapies that can specifically target abnormal gynecologic cell types and minimize off-target impact.

Priority: Research that develops safe and effective non-hormonal therapeutics and devices to treat gynecologic disorders such as endometriosis, emphasizing those that preserve fertility and are safe during pregnancy and lactation. 

Mechanisms of Chronic Gynecologic Pain

Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health
Strategic Plan Aspirational Goal: Accelerate efforts to definitively diagnose, prevent, and treat endometriosis

Gap: There is limited understanding of the prevalence, biological mechanisms, and clinical risk factors responsible for the development of gynecologic pain syndromes. New advances are needed in the area of gynecologic pain research, particularly considering the known gender differences in the perception of and treatment response to pain.

Priority: Multidisciplinary investigations to delineate the genetic, cellular, and molecular factors underlying the etiology and phenotypic expression of chronic gynecologic pain syndromes, with an emphasis on chronic pelvic pain due to endometriosis and vulvodynia.

Natural History Studies in Gynecology

Strategic Plan Theme 2: Promoting Gynecologic, Andrologic, and Reproductive Health
Strategic Plan Theme 4: Improving Child and Adolescent Health and the Transition to Adulthood
Strategic Plan Cross-Cutting Topics: Disease Prevention, Health Disparities

Gap: The natural history of gynecologic disorders has been poorly studied, particularly across periods of reproductive transition and in broadly representative populations.

Priority: Natural history studies that include relevant questions and appropriate biospecimen collection to better understand the risk factors and pivot points for treating and ultimately preventing these disorders. Of interest is the inclusion of patients across puberty, as well as health disparity populations.

  • Seminars in Reproductive Medicine. GHDB chief Dr. Lisa Halvorson served as one of the guest editors as well as author of two articles in the November 2020 issue: New Perspectives on Adenomyosis (PMID: 33232984). Adenomyosis, defined as the presence of endometrial tissue within the uterine muscle (myometrium), is associated with pelvic pain, pressure symptoms on the bowel and bladder, abnormal uterine bleeding, infertility, and pregnancy loss. The issue is a useful resource for clinicians and investigators and encourages increased study of this common disorder.
