Research Progress in Rat Models of Intrauterine Adhesion

doi:10.12300/j.issn.1674-5817.2022.025

Abstract

Abstract:

Intact endometrium and proper endometrial thickness are the necessary conditions for normal uterine reproductive function. Intrauterine adhesion (IUA) can cause recurrent abortion and infertility, which seriously affects the normal reproductive function of patients. At present, the treatment methods for IUA include surgery elimination and use of estrogen, but there are problems such as poor effectiveness, high rate of recurrence, and still with low pregnancy rate. The specific pathogenesis and developmental mechanism of IUA and the repair mechanism of damaged endometrium are still unclear. Establishing an appropriate animal model is conducive to the research of human IUA in all aspects. Here, we introduced the common rat models of IUA in recent years, including physical and mechanical damage method, chemical damage method, biological damage method and combined damage method, and described its application from the aspects of modeling rate, stability, and pathogenesis of IUA, and discussed the observation indexes to evaluate the success of modeling, in order to provide useful reference for selecting appropriate modeling methods. Generally, the combined model of repeated endometrial damage and infection of pregnant rats may be more suitable for the clinical IUA caused by multiple abortions and infections after curettage.
