Efficacy
Statistical methods / analysis
We estimated, using current data, that a significant difference in inflammation score could be standarized at 25%. Power of the study was calculated at 90%, using https://www.dssresearch.com power calculator, so each Group should have 50 enrollments (totally 100).
Statistical analysis of our results will take place using non-parametrical methods.

Summary
Brief summary
The aim of the study is to determine the effect of Serenoa Repens use on prostatic inflammation, based on histological and immunohistochemical criteria. Patients with prostatic inflammation based on biopsy results are randomized to receive either Serenoa Repens 320mg/d (Group 1) or no treatment (Group 2). Patients will receive a second biopsy 6 months later. Inflammation score and immunohistochemical results, with or without treatment with Serenoa Repens, will be statistically compared, so as to evaluate the effect on the prostatic inflammation.
