Research progress on intrauterine infusion therapy for recurrent implant failure
The rapid development of human assisted reproductive technology has improved the clinical pregnancy rate of infertile couples,but the pregnancy rate of patients with repeated implantation failure still remains low.Repeated implantation failure brings multiple pressures to patients' bodies,spirits and finances.Its'etiology is complicated,inclu-ding maternal factors,embryonic factors and male factors,among which the most important is the endometrial factor.In recent years,improving endometrial receptivity of patients with repeated implantation failure and promoting good preg-nancy outcome has become a reproductive hotspot.Uterine perfusion is an effective treatment method to improve endom-etrial receptivity,but it is still in the clinical research stage.Based on a large number of relevant data,this paper will review and analyze the progress of intrauterine perfusion on pregnancy outcome of repeated implantation failure,in order to provide clinicians with more extensive diagnosis and treatment ideas.
