Intention-to-treat analysis: Forest plot depicting odds ratio and 95% confidence interval for pregnancy outcome in the four randomized controlled trials on varicocele repair or observation in men with abnormal semen parameters and clinical varicocele [18–21]. The random effect model was used (heterogeneity χ2=14.60 [df=3]; p=0.024).
OR=odds ratio; CI=confidence interval.

“As-treated” analysis: Forest plot depicting odds ratio and 95% confidence interval for pregnancy outcome in the four randomized controlled trials on varicocele repair or observation in men with abnormal semen parameters and clinical varicocele [18–21]. The random effect model was used (heterogeneity χ2=7.41 [df=3]; p=0.060).
OR=odds ratio; CI=confidence interval.

4. Fig. 3
Forest plot depicting mean improvement (with 95% confidence intervals) in sperm concentration in the 22 prospective varicocelectomy studies in men with abnormal semen parameters and clinical varicocele. The random effect model was used (heterogeneity χ2= [df=21]; p < ) [18,35,49,56,63,64,67–81].
CI=confidence interval.

5. Fig. 4
Forest plot depicting mean improvement (with 95% confidence intervals) in percent sperm motility (total motility) in the 17 prospective varicocelectomy studies in men with abnormal semen parameters and clinical varicocele. The random effect model was used (heterogeneity χ2= [df=16]; p < ) [35,49,56,63,64,67,70–73,75,77–80,82].
CI=confidence interval.

6. Fig. 5
Forest plot depicting mean improvement (with 95% confidence intervals) in percent progressive sperm motility in the five prospective varicocelectomy studies in men with abnormal semen parameters and clinical varicocele. The random effect model was used (heterogeneity χ2=16.23 [df=4]; p=0.003) [18,68,69,74,76].
CI=confidence interval.
