Abstract
We examined the effects of preoperative hormonal values on varicocelectomy success. A total of 136 patients who underwent varicocelectomy for infertility in our clinic were analysed retrospectively. Improvement in semen quality was defined as >50% increase in post-operative total motile sperm count (TMSC) in those with preoperative TMSC >5million and at least 100% increase in those with <5 million. The patients were divided into two groups as benefiting from the treatment (Group A) and no benefits (Group B). The best cut-off value for follicle-stimulating hormone (FSH) and the luteinising hormone/testosterone ratio (LTR) that can predict varicocelectomy success were 7.01 and 0.016 with an area under the curve of 0.844 and 0.856 respectively. The highest sensitivities and specificities of FSH and LTR were 0.845 and 0.788 and 0.821 and 0.846 respectively. Binary logistic regression analysis showed FSH (odds ratio [OR]: 3.7; p<.001) and LTR (OR: 5.2; p<.001) as independent predictive factors in predicting varicocelectomy success. Our study demonstrated that low FSH (7.01IU/L) and LTR (<.016) can be a useful preoperative predictive tool to help identify men who benefit most from varicocelectomy in infertile patients with varicocele.
