Is there a relationship among age, international index of erectile function, international prostate symptom score,...

To investigate the relationship among the International Index of Erectile Function (IIEF), International Prostate Symptom Score (IPSS), and Aging Males' Symptoms (AMS) scale scores in various age groups of males.

A total of 307 male patients enrolled in the study. Mean age was 52.3 (range 21-77) years. Group 1 consisted of 51 (< or =39 years), Group 2 consisted of 160 (40-59 years), and Group 3 consisted of 96 (> or =60 years) patients. First five and 15th questions of the IIEF, IPSS, and AMS scale were replied by all the patients. The patients were assessed based on the IIEF for erectile dysfunction (ED), IPSS for lower urinary tract symptoms (LUTS), and AMS scale for Symptomatic Late-Onset Hypogonadism (SLOH).

ED, LUTS, and SLOH symptoms were detected in 236 (76.8%), 162 (52.8%), and 184 (59.9%) patients. Except for total AMS scores, IIEF and IPSS scores were significantly different among the groups (p (AMS) = 0.320, p (IIEF) = 0.000, p (IPSS) = 0.000). In the comparisons of the IIEF scores between the each group, significant differences were observed (p (Group1-Group2) = 0.000, p (Group1-Group3) = 0.000, p (Group2-Group3) = 0.000). Nevertheless, IPSS score was significantly lower in the patients with age < or =39 years than the other age groups (p = 0.000).

In the present study, ED ratio and LUTS severity significantly increased in older men. We did not find significant relationship between aging and SLOH symptoms. In the light of our results, LUTS seems to be an important risk factor on erectile function.
