Objective.

The objective of this study was to conduct a systematic review to assess the effectiveness and safety of traditional Chinese herb combined with surgery for male varicocele infertility compared to surgery.

Methods.

Randomized controlled trials (RCTs) data of traditional Chinese herbs combined with surgery for male varicocele fertility versus surgery were collected by searching the Cochrane Library, Embase, PubMed, and Chinese databases.

The risk of bias was assessed using Cochrane Handbook.

Study outcomes were presented as risk ratios (RRs) for dichotomous data.

Results.

Seventeen of 72 potentially relevant trials met the inclusion criteria.

The methodological qualities of the RCTs were low.

Compared with the surgery group, the traditional Chinese herb combined with surgery group had superiority in pregnancy rate at 3-month (RR=1.76, and P=0.008), 6-month (RR=1.58, and P=0.0005), and 2-year (RR=1.58, and P=0.0005) follow-ups.

No RCT was found to describe the side effects.

Conclusion.

On considering the low methodological quality of RCTs, there was no enough evidence on traditional Chinese herb with surgery for male varicocele infertility, and more high-quality RCTs of large sample sizes are required.
