The clinical value of acupuncture for women with premature ovarian insufficiency: a systematic review and meta-analysis of randomized controlled trials

Objective The aim of this study was to evaluate the therapeutic implications of acupuncture on improving ovarian function in women diagnosed with premature ovarian insufficiency (POI) through the implementation of randomized clinical trials (RCTs). Methods A comprehensive search of eight databases was conducted to identify RCTs up until 5 October 2023. The outcomes included the levels of sex hormones, antral follicle count (AFC), Kupperman score, and total effective rate. The risk of bias (RoB) tool was utilized to evaluate the quality of the included studies. In order to guarantee the robustness and reliability of the findings, subgroup and sensitivity analyses were performed to investigate potential sources of heterogeneity. Results A total of 13 RCTs comprising 775 patients were included in the study. Acupuncture demonstrated significant efficacy in reducing follicle-stimulating hormone (FSH) SMD = 0.83, 95% CI (0.27, 1.39), I 2 = 92%, p = 0.004, enhancing estradiol levels (E 2 ) SMD = 0.50, 95% CI (0.07, 0.93), p = 0.02, I 2 = 87%, and increasing anti-Müllerian hormone (AMH) SMD = 0.24, 95% CI (0.05, 0.44), p = 0.01, I 2 = 8%, as well as improving the overall effective rate RR = 1.22, 95% CI (1.10, 1.35), p 0.01, I 2 = 14%. Subgroup analysis revealed that compared with non-acupuncture therapy, the acupuncture with Chinese herbal medicine (CHM) and hormone replacement therapy (HRT) group exhibited a substantial reduction in FSH levels SMD = 1.02, 95% CI (0.52, 1.51), I 2 = 60%, p 0.01. Furthermore, the acupuncture with CHM group also exhibited a substantial reduction SMD = 4.59, 95% CI (1.53, 7.65), I 2 = 98%, p 0.01. However, only the acupuncture with CHM and HRT group demonstrated a significant increase in E 2 levels SMD = 0.55, 95% CI (0.23, 0.87), I 2 = 12%, p 0.01. Conclusion Acupuncture has demonstrated superiority over non-acupuncture in diminishing serum FSH levels and increasing serum E 2 , AMH, and the overall efficacy rate in women diagnosed with POI. These research findings suggest the necessity for broader-scale research with meticulous designs to fully demonstrate the efficacy and safety of acupuncture in the treatment of women with POI.
