Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a prevalent chronic urological disease. CP/CPPS severely impacts patients' quality of life. It is characterized by recurrent pelvic floor pain, lower urinary tract symptoms, and often accompanied by psychological issues and sexual dysfunction (duration ≥3 months, no confirmed infection/pathology). The investigators have completed a large-sample, multi-center randomized controlled trial (RCT) involving 440 patients with CP/CPPS before. The clinical trial confirmed the sustained efficacy of acupuncture for the symptoms of pain, lower urinary tract symptoms, and anxiety and depression among patients with CP/CPPS. However, the trial revealed no significant improvements in sexual dysfunction in the acupuncture group compared to the sham acupuncture group after 8 weeks of treatment.To address this limitation, the current study is designed, which aims to optimize the clinical acupuncture protocol for CP/CPPS and evaluate whether it can enhance outcomes for psychogenic erectile dysfunction (ED) associated. Additionally, mass cytometry and liquid suspension chip technology will be used to explore systemic and local immune mechanisms underlying acupuncture's effects for CP/CPPS. Functional magnetic resonance imaging (fMRI) and metabolomics will be integrated to analyze patients' systemic states from central nervous system and metabolic perspectives, comprehensively elucidating the multi-dimensional mechanisms by which acupuncture alleviates CP/CPPS.
