The introduced fluid serves as a carrier that contacts material present within the uterine cavity. After mixing, withdrawal collects suspended endometrial cells, microorganisms, secretions, and other intrauterine contents in a recoverable specimen. This allows investigators or clinicians to examine material from the uterine environment rather than relying only on the fluid itself.
A recovered lavage sample may contain cells from the endometrium, microorganisms, secretions, and other material located within the uterine cavity. The composition depends on what is present locally during sampling. Because several material types can be collected together, the specimen can support cytological, microbiological, or molecular evaluation.
Its purpose depends on the clinical context and the material being targeted. When the priority is sampling, the recovered fluid is examined for cellular, microbial, secretory, or molecular information. In other situations, introducing and withdrawing fluid can help remove intrauterine contents, making the same general procedure useful for different clinical aims.
The procedure begins by introducing sterile fluid into the uterine cavity through a catheter. The fluid is then allowed to mix with material present in the endometrium or uterine space. Afterward, the fluid is withdrawn, producing a recovered sample that can be retained for analysis or used to remove intrauterine contents.
Recovered lavage fluid can undergo cytological analysis to examine cellular material, microbiological analysis to investigate microorganisms, or molecular analysis to assess molecular features. These complementary approaches allow the same sample type to support different investigative goals, including evaluation of intrauterine inflammation, infection, reproductive disorders, and local uterine biology.
In medicine, uterine lavage supports investigation of intrauterine inflammation, infection, and reproductive disorders. Research applications extend beyond clinical investigation by using lavage fluid to study uterine biomarkers and local physiology. The method therefore provides a way to examine processes occurring within the uterine environment in both diagnostic and research settings.
