At present, the evaluation of endometrial receptivity (ER) is a routine research direction in the diagnosis and treatment of infertility, and it has been an key problem that have to be settled urgently in clinical practice. The definition of ER is the ability that endometrium receives embryo implantation, thereby the concept of implantation time windows was proposed. Ultrasound was applied to evaluate ER has series advantages included of convenience, safety, non-invasive and repeatability.
