Animal model of intrauterine adhesions and its application in the treatment of intrauterine adhesions

Abstract

Abstract:

Intrauterine adhesion (IUA) is the main cause of modern female infertility, which is mainly manifested by endometrial fibrosis. It is very important to establish a suitable animal model for the study of the mechanism of uterine adhesion. In this paper, we summarized the development process and methods of different animal uterine adhesion modeling, including the establishment of IUA models using mechanical injury, 95% ethanol injection, double injury, etc., to provide reference for researchers. At the same time, the current research progress on the treatment of uterine adhesions using IUA animal models is reviewed. Although the current popular stem cell therapy, platelet-rich plasma, and bioengineering technology continue to develop, the treatment of IUA has not been unified. In the future, it is still necessary to explore the pathogenesis of IUA to find the best treatment plan for IUA.

Key words: adhesions of uterus, animal model, treatment methods
