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.


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).


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.
