Abstract
OBJECTIVE: To analyze the effect of intrauterine infusion on platelet-rich plasma on hormone levels and endometrial receptivity of patients with repeated embryo implantation failure (RIF). METHODS: A total of 64 patients with repeated implantation failure and re-fertilization-embryo transfer who were admitted to our hospital from January 2019 to December 2021 were analyzed retrospectively. Among them were 30 patients who did not receive the platelet-rich plasma perfusion therapy. This became the control group (CG). The 34 patients who received the therapy were regarded as the research group (RG). The changes of hormone levels before and after the treatment and endometrial receptivity after the treatment were evaluated. The outcomes of IVF assisted pregnancy, including rates of embryo implantation, clinical pregnancy, and early miscarriage, were compared after the treatment. Risk factors for clinical pregnancy were analyzed by logistic regression. RESULTS: After treatment, the estradiol (E2) level increased and the follicle stimulating hormone (FSH) level decreased (P<0.05), but there was no marked difference in luteinizing hormone (LH) before or after the treatment (P>0.05). The E2 level in the RG was higher than that in the CG, and FSH in the RG was lower (P<0.05). In comparison to CG, the endometrial thickness on the day of human chorionic gonadotropin (hCG) injection and embryo transfer in the RG increased dramatically (P<0.05). The uterine artery pulsation index (PI) and uterine artery resistance index (RI) decreased (P<0.05). The embryo implantation and clinical pregnancy rates in the RG increased markedly (P<0.01), and the early abortion rate decreased significantly (P<0.05). The logistic regression analysis identified that age, number of transplant failures, treatment regimens, and FSH were risk factors for clinical pregnancy outcomes in patients. CONCLUSION: Intrauterine infusion of platelet-rich plasma can improve the hormone levels in RIF patients, increase endometrial thickness, and enhance endometrial blood flow, increasing the pregnancy rate of patients and improving clinical pregnancy.
