The International Federation of Gynecology and Obstetrics FIGO is an international organization that links about international professional societies of Obstetricians and Ffigo. In FIGO recognized two systems designed to aid research, education, and clinical care of women with abnormal uterine bleeding AUB in the reproductive years.

FIGO classification of uterine bleeding – Wikipedia

This page is a summary of the systems and their use in contemporary gynecology. Abnormal uterine bleeding AUB in the reproductive years, unrelated to pregnancy, is rarely life-threatening, but is frequently life altering. The symptoms frequently interfere with quality of life and those girls and women afflicted with chronic AUB spend significant amounts of personal resources on menstrual products and medications.

Such women are 30 per cent less productive at work, and, consequently, suffer a similar reduction in income. The problem of AUB burdens the economy, employers, as well as women and their families. With the massive clwssification impact of both acute and chronic AUB, the relevance of safe and effective clinical care cannot be overestimated.

Although common sense interventions such as iron therapy are often underused in developed countries and frequently unavailable in developing nations, these and related classificatino deal with reducing the consequences HMB the symptom, not the cause itself.


Abnormal uterine bleeding in the reproductive years comprises a complex set of disorders that include abnormalities in endocrine, endometrial and clzssification function and a number of structural anomalies that fio polyps, adenomyosis and leiomyomas or fibroids.

Determination of the causes of AUB in the reproductive years remains a major challenge for investigators, clinicians and educators. Investigators have to conceive and classitication execute relevant bench and clinical investigation; clinicians must deal with the patient in their office or hospital and educators of medical students and postgraduate trainees such as residents and fellows are encumbered with the task of providing a mechanism for understanding AUB that facilitates proper investigation and therapy.

For a number of investigators and educators, it became apparent that there were at least two major impediments to dealing with these challenges.

The first was a disjointed collection of poorly defined and inconsistently used terms and definitions that undermined effective communication among investigators, clinicians and trainees classififation. These circumstances lead to difficulties with the interpretation of both basic science research and clinical trials as since specimens and patients could be “contaminated” with potential confounders. As a result, in order to obtain clearly informative basic science as well as translational and clinical investigation, a comprehensive approach to both investigation and clwssification was needed.

Starting ina group of experts that comprised those from the FDA, related professional societies and gynecologic medical journals, and representatives from the basic, translational, and clinical sciences were assembled to tackle the issues in claxsification systematic fashion. The development of these systems was in large part based upon a process was conducted using RAND’s Delphi process. The results allowed for a collective recognition of the disparity and inconsistency in definitions and terminology a circumstance that was a surprise to many.


The result of this process was a near unanimous decision to create a new set of descriptive and unambiguous terms that could be translated into a wide spectrum of languages.

Coagulopathies require confirmation by laboratory testing, while, at least for fibo present, ovulatory and endometrial disorders are primarily, and at least clinically, defined by a structured history. Irregular ovulation or anovulation can be supported by a number of laboratory and histopathological assessments, not typically applied in clinical settings.

It is recognized that each of the major categories may include subgroups that are known or suspected to have clinical relevance.

Added clwssification a category for submucous myomas that make contact with the endometrium but do not distort the endometrial cavity Type 3and subclassification for intramural leiomyomas and the various types of subserous myomas.
