Abstract
BACKGROUND
Acupuncture (AT) is widely used in treatment of ovulatory disorder infertility (ODI), but the safety and efficacy of AT for ODI still lack an evidence-based basis.
AIM
To evaluate the feasibility and effectiveness of AT as an adjunct intervention for ODI.
METHODS
The Cochrane Library, Embase, PubMed, VIP, China National Knowledge Infrastructure, WanFang Data, and Chinese biomedical literature databases were searched from inception to January 20, 2024. Two reviewers independently selected studies, collected data, and evaluated methodological quality through the Cochrane Risk of Bias tool. Revman 5.4 was used for meta-analysis, and the Grade system was performed to evaluate the level of evidence for the outcomes of the meta-analysis.
RESULTS
A total of 20 randomized controlled trials with 1677 ODI patients were included. Compared with the clomiphene citrate (CC) group, the AT plus CC group exhibited significant improvement of the pregnancy rate [relative risk (RR) = 1.68, 95% confidence interval (CI): 1.45-1.95, P < 0.00001, I2 = 23%], ovulation rate (RR = 1.34, 95%CI: 1.22-1.47, P < 0.00001, I2 = 32%), serum E2 level [mean difference (MD) = 31.36, 95%CI: 21.83-40.88, P < 0.00001, I2 = 97%], thickness of endometrium (MD = 1.76, 95%CI: 0.71-2.81, P = 0.001, I2 = 98%) and decreasing miscarriage rate (RR = 0.25, 95%CI: 0.09-0.65, P = 0.005, I2 = 0%), serum follicle-stimulating hormone level (MD = -2.10, 95%CI: -3.27 to -0.94, P = 0.0004, I2 = 99%), serum luteinizing hormone level (MD = -6.94, 95%CI: -9.89 to -4.00, P < 0.00001, I2 = 100%), and serum progesterone level (MD = -1.66, 95%CI: -2.98 to -0.34, P = 0.01, I2 = 96%). The AT group had a more favorable effect than CC group for improving pregnancy rate (RR = 1.52, 95%CI: 1.33-1.73, P < 0.00001, I2 = 0%), thickness of endometrium (MD = 2.48, 95%CI: 2.15-2.81, P < 0.00001, I2 = 0%) and reducing miscarriage rate (RR = 0.23, 95%CI: 0.13-0.44, P < 0.00001, I2 = 0%), serum follicle-stimulating hormone level (MD = -0.55, 95%CI: -0.86 to -0.24, P = 0.0005, I2 = 0%), and serum progesterone level (MD = -0.24, 95%CI: -0.28 to -0.20, P < 0.00001). However, the level of evidence was predominantly assessed as very low to moderate.
CONCLUSION
AT can improve the pregnancy outcomes and sex hormone levels for patients with ODI. However, further studies are needed to confirm these findings.
