[Effect of Wenyang Huazhuo acupuncture therapy on endometrial receptivity and pregnancy outcomes in patients with repeated implantation failure of spleen and kidney yang deficiency pattern].

Chinese researchers studied whether a specialized acupuncture approach called "Wenyang Huazhuo" (warming yang and resolving turbidity) could help women experiencing repeated implantation failure during IVF treatment. The study included 73 women who had experienced multiple failed embryo transfers and were diagnosed with "spleen and kidney yang deficiency" according to traditional Chinese medicine principles. Half received standard frozen embryo transfer procedures, while the other half received acupuncture treatments three times weekly for two months before their embryo transfer, with 30-minute needle retention each session. The results were significant: women receiving acupuncture had substantially higher clinical pregnancy rates, embryo implantation rates, sustained pregnancy rates, and live birth rates compared to the control group. Ultrasound measurements showed that acupuncture improved endometrial thickness and blood flow patterns, creating more favorable conditions for embryo implantation. Laboratory analysis revealed that acupuncture increased levels of three important proteins (HOXA10, ITGB5, and LIF) in the uterine lining that are known to support embryo implantation. This study suggests that for women experiencing repeated IVF failures, particularly those with cold-pattern symptoms in traditional Chinese medicine diagnosis, acupuncture may significantly improve the chances of successful pregnancy and live birth by enhancing the uterine environment. If you're considering acupuncture for fertility support, seek a licensed acupuncturist with specialized training in reproductive health and experience working alongside fertility clinics.

This randomized controlled trial examined Wenyang Huazhuo acupuncture in 73 women with repeated implantation failure and spleen-kidney yang deficiency. The treatment group (n=36) received acupuncture three times weekly for two months prior to frozen embryo transfer (FET), with 30-minute needle retention. Control group (n=37) received standard FET only. Results showed statistically significant improvements in the treatment group: increased clinical pregnancy rate, embryo implantation rate, sustained pregnancy rate, and live birth rate (P<0.05-0.01). Ultrasound findings revealed significantly increased endometrial thickness, higher Type A endometrial morphology rates (P<0.01), and decreased uterine artery resistance index (P<0.01). Western blot analysis demonstrated significant upregulation of mid-luteal endometrial receptivity markers HOXA10, ITGB5, and LIF (P<0.05-0.001). The mechanism appears to involve enhanced endometrial receptivity through improved protein expression and uterine hemodynamics. This represents promising evidence for acupuncture as adjunctive therapy in recurrent IVF failure cases with yang deficiency patterns.
