Effects of acupuncture on ovarian blood supply and pregnancy outcomes in patients receiving assisted reproduction

Pregnancy Benefit of Acupuncture on in vitro Fertilization: A Systematic Review and Meta-Analysis

BACKGROUND

Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate.

OBJECTIVE

To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis.

METHODS

Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I2 statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests.

RESULTS

A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I2=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I2=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I2=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I2=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence.

CONCLUSION

Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings. (Registration No. PROSPERO CRD42021232430).

Acupuncture and Chinese Herbal Medicine Effects on Assisted Reproductive Technology: Six Cases and Their Clinical Significance

Background: Assisted reproductive technology (ART) is the routine treatment for infertility. The success rate for individual sessions is generally not high, and many patients need to undergo several cycles. To increase their chances of success, many patients turn to acupuncture to complement ART. Many clinical trials of acupuncture helping in vitro fertilization (IVF) have focused only on IVF-embryo transfer (ET). In some difficult cases, when even IVF cannot be offered, acupuncture and Chinese herbs can improve the patients' conditions to reach a level at which ART can be successful. Cases: Six cases showed how acupuncture and Traditional Chinese Medicine (TCM), using Chinese herbs, can make IVF possible in difficult cases and how they can also help prevent miscarriage afterward. The cases included patients with amenorrhea, sperm disorders, polycystic ovary syndrome, diminished ovarian reserve (DOR), tubal blockage, premenopause, and premature ovarian insufficiency. Results: Acupuncture and Chinese herbs worked together to help make ART possible or easier. The ART used for these patients included intrauterine insemination, IVF, IVF with a donor egg, and introcytoplasmic sperm injection. In 3 cases, IVF was not initially successful but was successful after TCM treatment. Conclusions: These 6 cases demonstrated the positive effect of a combined approach, using acupuncture and herbs to reduce DOR and regulate hormonal disorders, creating sustainable environments for conceiving and maintaining pregnancy, thus, translating into clinical success. Clinical observation of these cases sheds new light on designing future clinical trials and practice of TCM for practitioners who provide infertility treatments.
