Abstrakt:	Background/aim: Testosterone is essential for prostate cancer development and growth. This study aimed to investigate the relationship between testosterone in seminal vesicles and prostate cancer incidence and its malignant phenotype. Patients and Methods: After obtaining institutional review board approval, seminal vesicle fluid samples were collected from patients who underwent prostatectomy or cystectomy. Pathological review demonstrated that 26 patients had benign prostate tissue and 149 had prostate cancer. First, testosterone levels in seminal vesicle fluid from benign prostate and prostate cancer samples were compared. Next, the relationship between pathological stage, International Society of Urological Pathology (ISUP) score, and testosterone concentrations in seminal vesicle fluid in the prostate cancer group were examined. Results: Testosterone in seminal vesicles was significantly higher in the prostate cancer group [median (range), 1.94 (0.17-4.32) ng/ml] than in the benign prostate group (mainly bladder cancer) [1.45 (0.60-2.78) ng/ml] (p=0.001). Testosterone in seminal vesicles showed no difference in relation to pathological stage (pT2 vs. pT3) or ISUP score (12 vs. 345) (p=0.480 and p=0.964, respectively). Neoadjuvant chemotherapy for other cancers (e.g., bladder or rectal cancer) significantly reduced testosterone in seminal vesicles (p=0.013). Multivariate regression analysis revealed that testosterone in seminal vesicles was significantly correlated with prostate cancer, and not with neoadjuvant chemotherapy (p=0.023, p=0.457, respectively). Conclusion: Testosterone in seminal vesicles may contribute to prostate cancer incidence, but has no relationship with pathological grading.
