The Clinical Efficiency of Tb-ERA in Chinese RIF Patients

The Clinical Efficiency of Transcriptome-based Endometrial Receptivity Assessment (Tb-ERA) in Chinese Patients With Recurrent Implantation Failure (RIF)

In order to further explore the clinical utility of endometrial receptivity array in patients with repeated implantation failure, the patients divide into the experimental group or the control group. In the experimental group, those patients undergo endometrial receptivity array. In the control group, those patients do not receive any treatment before next cycle of transfer. In the experimental group, according to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out. Statistical analysis of the two groups of primary endpoint and secondary endpoint are done.

Study Overview

• Status: Completed
• Conditions: Endometrial Receptivity; Repeated Implantation Failure
• Intervention / Treatment: Diagnostic test: Endometrium biopsy

Detailed Description

In the field of assisted reproduction techonology, there are still 10% of patients with repeated implantation failure. In order to further explore the clinical utility of endometrial receptivity array in patients with repeated implantation failure, the patients divide into the experimental group or the control group. In the experimental group, those patients undergo endometrial receptivity array. In the control group, those patients do not receive any treatment before next cycle of transfer. In the experimental group, according to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out. In the control group, no intervention will be performed. Statistical analysis of the two groups of primary endpoint (clinical pregnancy rate) and secondary endpoint (endometrial implantation window evaluation results, embryo implantation rate, biochemical pregnancy rate, early abortion rate, ectopic pregnancy rate) are done. Through the comparative analysis of clinical outcomes to verify the clinical efficacy of endometrial receptivity analysis in patients with repeated implant failure, this method will provide a new treatment for repeated implant failure population.

Experimental: ERA group; In the experimental group, those patients undergo endometrial receptivity array. According to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out.	Diagnostic test: Endometrium biopsy; In the experimental group, those patients undergo endometrial receptivity array. In the control group, those patients do not receive any treatment before next cycle of transfer. In the experimental group, according to the results of endometrial receptivity array, the transplantation time will be adjusted and retransplantation will be carried out. In the control group, no intervention will be performed.
No Intervention: Control group; In the control group, those patients do not receive any treatment before next cycle of transfer. In the control group, no intervention will be performed.
