简要总结
At present, the evaluation criterion of endometrial receptivity is controversial. The development of a molecular diagnostic tool, the endometrial receptivity array (ERA) for diagnosis of endometrial receptivity . But use of this test in patients with RIF has shown that the window of implantation (WOI) is displaced in only a quarter of these patients and use of a personalized embryo transfer (pET) on the day designated by ERA improves reproductive performance with higher cost .what is known to the others'population? The morphological changes observed on histology for each specific day after ovulation were described by Noyes and his colleagues in 1950 . An endometrial biopsy that shows a difference of more than 2 days between the histologic dating and actual day after ovulation is considered to be ''out of phase''. But such pET studies according to the Noyes criterion are lacking . The aim of this study is to explore the transcriptomic profile of endometrial receptivity in different histological dating of natural cycle and its clinical application.
