Systemic immune‐inflammation index, neutrophil‐lymphocyte ratio and platelet‐lymphocyte ratio are predictors of sperm presence in microdissection testicular sperm extraction

The aim of this study is to evaluate the value of the haematologic inflammatory parameters in predicting sperm retrieval rates during microdissection testicular sperm extraction (micro‐TESE).159 patients diagnosed with non‐obstructive azoospermia were included in the study.

description The aim of this study is to evaluate the value of the haematologic inflammatory parameters in predicting sperm retrieval rates during microdissection testicular sperm extraction (micro‐TESE).159 patients diagnosed with non‐obstructive azoospermia were included in the study. After excluding the patients that do not fit the inclusion criteria, age, smoking status, body‐mass index, serum luteinizing hormone, follicle‐stimulating hormone, total testosterone levels and neutrophil, lymphocyte and platelet counts were recorded. Neutrophil‐lymphocyte ratio, platelet‐lymphocyte ratio and systemic immune‐inflammation index were calculated. The primary outcome was defined as the presence of spermatozoa during the procedure and the association between the candidate predictors and primary endpoint were evaluated by logistic regression analysis. Then, a baseline model from age, smoking, body‐mass index and hormonal levels was built. Ratios and indexes were included, respectively, and were compared by multivariate analyses. Each of all three parameters was an independent predictor of obtaining spermatozoa during micro‐TESE procedure (all p
