Abstract:

Embryo implantation is a complicated and sophisticated process, which is mainly regulated by embryo, endometrium and the interaction between the two. With the development of embryo laboratory technology, the embryo quality and embryo selection system have been improved significantly. However, the evaluation system and standard of endometrial receptivity have not been clarified yet. In recent years, the accurate assessment of endometrial receptivity has become a focus with the proposal of personalized embryo transfer (pET). More and more researches were focused on how to assess endometrial receptivity, from the initial ultrasound and pinopodes examination to various molecular markers, and to endometrial receptivity array, endometrial receptivity profile and proteomics, lipidomics and other indicators. The author hereby reviews various indicators for evaluating endometrial receptivity. It is helpful for the future work and study, such as individualized embryo transfer, so as to improve clinical pregnancy rate and live birth rate.

Key words: Embryo implantation, Proteomics, Endometrial receptivity, Endometrial receptivity array, Personalized embryo transfer
