About this study
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.

personal embryo transferProcedure or surgery
According to the histological dating and transcriptomic profile of endometrium of natural cycle in control group, to explore the effectiveness of intervention by advanced or delayed personal embryo transfer .
The establishment of standard control group: Frozen embryo transfer patients according to the inclusion and exclusion criteria were evaluated for histological dating and transcriptomic profile by endometrial biopsy on 7 days after ovulation. After routine time transfer in the frozen embryo transfer cycle, the standard of histological dating and transcriptomic profile were determined according to the pregnancy. outcome of the FET cycle .

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
clinical pregnancy rate (time frame: at least one intrauterine gestational sac with cardiac action by ultrasound performed 28 days after embryo transfer). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03222830, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jan 2022.
