Objective: To evaluate of the correlation between lower urinary tract symptoms (LUTS), and premature ejaculation (PE) in Korean men aged more than 40 years old.

Material and Methods: A total of 258 men aged more than 40 years old presenting were studied by questionnaires which were composed of International Prostate Symptom Score [IPSS: total scores, storage symptoms (ST), voiding symptoms (VD)], 5-item version of the International Index of Erectile Function (IIEF-5) and Premature Ejaculation Diagnostic Tools (PEDT). Comparative analysis was done to examine the relationship between lower urinary tract symptoms (LUTS) and premature ejaculation (PE). PE in PEDT was defined as higher than 11 score.

Results:. In PEDT, prevalence of PE was 29.1 percent, and PE to be reported by themselves was 49.5 percent. In 40-59 years old men(21.3%), prevalence of self-reported PE was 30.9%, and in 60-79 years old men(78.7%), 28.1%. Mean of PEDT score in 40-59 years old and in 60-79 years old were 8.65 and 7.88, respectively. Mean of IPSS total score was 13.5 in 40-59 years old and 12.38 in 60-79 years old. Mean of IIEF-5 score was 15.83 in 40-59 years old and 13.69 in 60-79 years old.

There were no significant correlation in the total score, ST- and VD-subscale scores of the IPSS (p=0.204) and PEDT score (p=0.309) with age. But, there were significant correlation between IIEF-5 and age (p=0.002). Also the PEDT score showed significant coefficient correlation with ST-IPSS (r=0.326, P<0.001), VD-IPSS (r=0.183, P=0.005), total IPSS (r=0.310, p<0.001) and IIEF-5 (r=-0.248, p<0.001).

Conclusions: Even though PE was not associated with age, PE was significantly related with not only LUTS, especially storage symptoms but erectile function. This data suggested that control of both erectile dysfunction and LUTS may play a important role in management of PE in elderly men
