Clinical observations of sequential therapy with Chinese medicine and hysteroscopic mechanical stimulation of the endometrium in infertile patients with repeated implantation failure undergoing frozen-thawed embryo transfer / 中国结合医学杂志

<p><b>OBJECTIVES</b>To investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.</p><p><b>METHODS</b>In the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.</p><p><b>RESULTS</b>Endometrial thickness, E2 and P levels, and the E2/P ratio on embryo transfer day and other factors had no significant differences among groups. The biochemical pregnancy, clinical pregnancy, and implantation rates of the CM and hysteroscopy groups were significantly higher than the control group (P<0.05), and there were no significant differences between these two groups. The abnormal pregnancy rate had no significant difference among the three groups.</p><p><b>CONCLUSIONS</b>Sequential therapy of Yupei Qisun could significantly improve the clinical outcomes of rif-fet cycles, being equivalent to hysteroscopic endometrial mechanical stimulation, and provided a reliable method to treat such infertile couples.</p>

Effects of Yupei Qisun Sequential Method of Chinese medicine on correlated indices of repeated implantation failure patients in the fresh cycle / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the clinical effects of Yupei Qisun Sequential Method (YQSM, by Shen supplementing and Pi invigorating) of Chinese medicine on correlated indices of repeated implantation failure patients in the fresh cycle.</p><p><b>METHODS</b>Sixty patients with more than three failure cycles of in virto fertilization and embryo transfer (IVF-ET) or intracytoplasmic sperm injection (ICSI) were recruited. They were assigned to the treatment group (treated by IVF/ICSI and Chinese medicine) and the control group (treated by IVF/ICSI alone), 30 in each group. The total dose of gonadotropin (Gn), the days of controlled ovary hyperstimulation (COH), the thickness of endometrium on the day of embryo transplantation, the number of retrieved oocytes, the fertilization number, the embryo number, the high quality embryo number, the pregnancy rate, and the implantation rate were compared.</p><p><b>RESULTS</b>In the treatment group the numbers of embryo and high quality embryo were 7.5 +/- 4.9 and 5.1 +/- 3.2 respectively, which were both higher than those of the control group with significant difference (5.1 +/- 3.2, 3.2 +/- 1.8; P < 0.05). No significant difference existed in aspects of the total numbers of Gn, the days of COH, the thickness of endometrium on the day of embryo transplantation, the numbers of retrieved oocytes, the fertilization number, the pregnancy rate, and the implantation rate between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>YQSM combined with COH could improve the quantity and the quality of embryos, which was promising to increase the accumulative pregnancy rate of RIF patients.</p>
