Abstract:

Objective: To investigate the factors affecting the clinical outcomes of patients with repeated implantation failure (RIF) following hysteroscopy and endometrial biopsy, and to provide references for improving the clinical pregnancy rate of RIF patients.Methods: From September 2015 to September 2017, a total of 136 patients undergoing hysteroscopy and endometrial biopsy in our hospital were eligible for this study. All patients were diagnosed with RIF. Patients were divided into two groups (pregnancy group and non-pregnancy group) according to the presence of clinical pregnancy after the first embryo transplantation. Data of age, height, weight, infertility years, infertility types, hysteroscopy period (endometrial proliferation/secretion), transplant failure times, endometrial thickness, transfer cycle, time between transplantation and hysteroscopy, embryo type and number of embryos were collected by respectively reviewing patients′ medical records. Univariate analysis and multivariate logistic analysis were used to explore the influencing factors of clinical pregnancy following hysteroscopy and endometrial biopsy.Results: The incidence of clinical pregnancy following hysteroscopy and endometrial biopsy was 51.5% (70 of 136 cases). Univariate analysis showed the statistical differences in age and the type of embryo between the two groups (P<0.05). Multivariate Logistic regression analysis confirmed that the age (OR=1.160, 95%CI: 1.041-1.292) and type of embryo transplanted (OR=0.307, 95%CI: 0.108-0.873) were the influencing factors for the second pregnancy of patients with RIF after hysteroscopy.Conclusions: It is relatively easy for younger patients and those patients accepting blastocyst transplantation to obtain clinical pregnancy following the hysteroscopy and endometrial biopsy. The treatment timing of hysteroscopy and endometrial biopsy in the menstrual cycle is not a factor affecting the clinical pregnancy after the first postoperative embryo transfer.
