Abstract
Background: Increasing studies focused on the efficacy of acupuncture on pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization-embryo transfer (IVF-ET). However, debatable conclusions have been drawn from different randomized controlled trials (RCTs), which might be related to different doses of acupuncture.
Objective: To evaluate whether acupuncture has a dose-dependent effect on pregnancy outcomes in patients with PCOS undergoing IVF-ET in systematically reviewing.
Methods: Seven electronic databases were searched from inception to October 10th, 2024. The Cochrane Collaboration's tool ROB 2.0 (ROB 2.0) provided an assessment for the risk of bias. The acupuncture dose was extracted, then categorized into high, medium, and low dose according to the scoring system results, the evidence was assessed by Slavin's qualitative best-evidence synthesis approach in a rigours methodological way. Clinical pregnancy rate (CPR) was regarded as the primary outcome.
Results: A total of 953 subjects met the eligibility criteria in 12 RCTs were included, among which two studies were low dose, four were medium dose, and six were high dose. The overall quality of included studies was low, 50.00% (6/12) studies were low risk, 16.67% (2/12) studies were some concerns, and 33.33% (4/12) studies were high risk. Comparing the results, the consistent high-dose result among high-quality trials provides strong evidence for a positive correlation between high-dose acupuncture and pregnancy outcomes.
Conclusion: A trend indicates that higher acupuncture doses yield better outcomes for PCOS patients undergoing IVF-ET. Further confirmation through direct comparisons of different doses was needed.
Trial registration: The systematic review has been registered on PROSPERO ( https://www.crd.york.ac.uk/prospero/ ), and the registration number is CRD42023400187.
