Abstract

Introduction: The most common sexual dysfunctions in men are premature ejaculation (PE) and erectile

dysfunction (ED). There is little data about the existence of these two pathologies with each other. The aim of

this study is to determine frequency and severity of erectile dysfunction in patients with premature

ejaculation, and to compare with healthy controls.

Materials and Methods: Forty-eight patients suffering from PE, who are married and/or have a regular

sexual partner, were included in this study. The patients who had additional causes of ED like diabetes

mellitus, coronary cardiac disease, and hepatic or renal failure were excluded from this study. PE was defined

as the erection loss with ejaculation before vaginal penetration or within 2 minutes of penetration in more than

50% of sexual intercourse. Age matched 30 men who applied to our clinic for reasons other than sexual

problems were taken as a control group. International Index of Erectile Function (IIEF) was applied to all

subjects in both groups and erectile function domain scores (IIEF_ED) were calculated with 1-5 and 15th

questions of the IIEF questionnaire. ED was classified into four categories based on the scores: severe (6-10),

moderate (11-16), mild (17-25), and no ED (26-30). Patients who had severe and/or moderate ED were

described as the complete ED. In statistically analysis, independent samples t-test, chi-square and correlation

analysis were used. Significance was defined as p<0.05. Statistical tests were performed by using the SPSS

statistical package.

Results: The results are given as mean ± standard deviation of mean. The mean ages of the patient and

the control groups were 31.68±7.94 (range 20-55) and 29.40±6.26 (range 19-46) years, respectively. There was

no significant difference between mean age of groups. The mean erectile dysfunction domain score of the

patients with PE and controls were found 18.85±4.96 and 26.73±4.40, respectively (p<0.001). Although ED was

found in 36 (75%) of patients with PE, it was determined only in 6 (20%) of control subjects, and the

difference between groups was statistically significant (P<0.05).

Conclusion: Premature ejaculation is one of the most common and an important sexual problem in

sexually active males. The prevalence of ED in patients with PE is controversial. In our study, highly prevalent

and severe ED was found in the patients with PE to compare with control group, according to IIEF_ED

domain score. In conclusion, the presence of the ED in the patients with PE must
