We searched for relevant trials registered up to May 2013 in 14 databases. We selected randomized controlled trials (RCTs) that compared acupuncture, with or without additional treatment, against placebo, sham, no treatment, or the same additional treatment. Two reviewers independently performed the study selection, data extraction, risk of bias and reporting quality appraisal. Risk of bias and reporting quality were appraised by the Cochrane risk of bias tool, the consolidated standards of reporting trials and Standards for Reporting Interventions in Clinical Trials of Acupuncture. The outcomes were sperm motility, sperm concentration, pregnancy rate, and adverse events. Pregnancy was defined as a positive pregnancy test. Four RCTs met the eligibility criteria. Acupuncture increased the percentage of sperm with rapid progression (mean difference - 6.35, 95% confidence interval (CI). 4.38-8.32, P〈 0.00001) and sperm concentration (mean difference - 6.42, 95% CI. 4.91-7.92, P〈 0.00001), but these two outcomes were substantially heterogeneous among the studies (F = 72% and 58%, respectively). No differences in pregnancy rate were found between acupuncture and control groups (odds ratio 1.60, 95% CI. 0.70-3.69, P= 0.27, F = 0%). No participants experienced adverse events. The current evidence showing that acupuncture might improve poor semen quality is insufficient because of the small number of studies, inadequacy of procedures and/or insufficient information for semen analysis, high levels of heterogeneity, high risk of bias, and poor quality of reporting. Further large, well-designed RCTs are required.展开更多

Methods: Seven medical journal databases were searched including PubMed, EMBASE, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Oriental Medicine Advanced Searching Integrated System, KoreaMed, and Korean studies Information Service System using 10 candidate terminologies as searching terms. All studies published from their inception to July 26, 2017 were collected. Articles were included if the title stated one of the 10 candidate terminologies consistent with the definition of acupotomy. Priorly established frequency and consistency of each candidate terminology from medical databases were calculated and evaluated. Moreover, the pros and cons of each were analyzed to propose a standard terminology. Results: A total of 112 studies in English databases, 1,129 studies in Chinese database, and 44 studies in Korean databases were included. The most frequently used terminologies were needle knife(35.71%), acupotomy(48.54%) and acupotomy(90.90%) in English, Chinese and Korean database, respectively. Overall, acupotomy and needle knife were the most frequently used. Others like acupotomology, needle scalpel, miniscalpel acupuncture and miniscalpel needle were used within 10% of the total searched literature. Acupotome, stiletto needle, sword like needle, and Xiaozhendao were rarely used. Acupotomy had the advantages of high frequency and consistency but lacked representativeness. Needle knife also showed a high frequency, but the consistency was poor. Though miniscalpel acupuncture and miniscule needle were used less frequently, they had advantages of inclusiveness and clarity. Conclusions: A debate for standardization of the terminology is necessary. This preliminary research can provide a basic outline for the standardization consensus process, and we believe it is noteworthy to discuss miniscalpel needle and miniscalpel acupuncture along with acupotomy and needle knife on the subject.展开更多
