Various studies have been reported to predict the success of varicocelectomy. Neutrophil-lymphocyte ratio (NLR) is a frequently used indicator of systemic inflammation. We aimed to evaluate the effect of inflammation on the success of varicocelectomy using the NLR. The data of 86 patients who underwent varicocelectomy for infertility were evaluated retrospectively. Pre-operative demographic characteristics of patients, laboratory results such as haemogram, and semen analysis and clinical data were recorded. The semen analysis with the highest total motile sperm count was accepted as pre-operative value. Control was performed with semen analysis at post-operative 6th month. As described in previous studies, in our study, more than 50% increase in total motile sperm count in post-operative semen analysis was defined as a significant improvement. However, at least a 100% increase was required for patients with a total motile sperm count <5 million in the definition of recovery. Patients were divided into two groups as those with improvement in the semen parameters (Group 1) and those without (Group 2). NLR was statistically significantly higher in Group 2 compared with Group 1. The area under the curve (AUC) in the ROC curve for NLR was 0.89. According to the Youden index, the best cut-off value of NLR for varicocelectomy success was 1.98 (sensitivity: 94.7%, specificity: 75.9%, p < 0.001). Logistic regression analysis showed that NLR (odds ratio: 3.6, 95% confidence interval: 1.69-8.38, p < 0.001) is independent predictor factors in predicting the success of varicocelectomy. The results of this study show that systemic inflammation adversely affects the likelihood of improvement in sperm parameters by varicocelectomy. Additionally, NLR has been shown to be an independent factor in the prediction of varicocelectomy success.
