Erectile dysfunction (ED) are common problem in males with lower urinary tract symptoms suggestive (LUTS).The aim of this study is to evaluate whether there is an association between PSA levels and ED or not. This study included total of 54 males aged 45-75 years old, who attended in department of urology. International Prostate Symptom Score (IPSS) was used for LUTS measurements. The International Index of Erectile Function questionnaire-5 (IIEF) was used ED measurements. We evaluate the relationship between PSA and ED or LUTS. Patients were divided into3 groups according to PSA level. Group 1: 0,1-1,3 ng/dl, group 2: 1,3-3,2ng/dl and group 3: 3,2-10 ng/dl. The IPSS score was 16,9 in group 1, 18,1 in group 2 and 21 in group 3. The IIEF score 16,4/14,1/13,8 respectively. The severity of ED or LUTS was associated with the PSA level. PSA showed a significant positive correlation with ED and LUTS. In group 1 patients having lowest PSA level, sexuel function was better. ED was positively correlated with LUTS. ED and LUTS were significantly and independently correlated with PSA level. PSA may be a predictor factor for ED. But, there was no significant difference between PSA level and ED. Nevertheless, multicenteric, controlled, long-term, randomized studies are needed.
