AGE-RELATED CORRELATION BETWEEN ERECTILE DYSFUNCTION AND PREMATURE EJACULATION

초록

Background and objective To evaluate the relationship between erectile dysfunction (ED) and premature ejaculation (PE) among men aged 40-79 years and to compare age-related differences between men aged 40-59 years and 60-79 years. Materials and methods From January 2014 to January 2019, records of 892 men aged 40-79 years were analyzed. We performed correlation analysis using the self-reported intravaginal ejaculation latency time (IELT), premature ejaculatory diagnostic tool (PEDT), Male Sexual Health Questionnaire-ejaculation (MSHQ-EjD), and International Index of Erectile Function5 (IIEF5) questionnaires. Results The mean age of the 892 males was 52.8 +/- 7.3 years (40-76). All subjects were divided into group 1 (40-59 years old) and group 2 (60-79 years old). The IIEF5 score of group 1 was significantly higher than that of group 2 (18.7 +/- 5.5 vs. 17.7 +/- 5.7, p = 0.049). Of the total subjects, 71 (8%) had IELT value of less than 1 min. A total of 51 (6.9%) and 20 (13.5%) were in groups 1 and 2, respectively (p = 0.02). The PEDT total score was higher and more subjects were identified as suffering from PE (PEDT = 9) from amongst the ED subjects (IIEF-5 = 21). In both groups 1 and 2, more PE subjects were identified in ED subjects (IIEF-5 = 21) than normal subjects (IIEF-5 > 21) (all p < 0.01). In the total subjects, group 1 and 2, the IIEF-5 and PEDT score showed a weak negative correlation (r = -0.302, r = -0.361, r = -0.248, all p < 0.01). In group 2, the IELT and MSHQ-EjD score also showed a weak positive correlation between the IIEF-5 score (r = 0.166, p = 0.044 and r = 0.164, p = 0.047, respectively). Conclusion More subjects defined PE value as less than 1 min on the self-reported IELT in the elderly group =60 years than those among the 40-59 years age group; moreover, the lower the IIEF5 total score among subjects = 60 years, the higher the PEDT score and the lower the IELT and MSHQ-EjD scores.
