Introduction: Premature ejaculation (PE) and erectile dysfunction (ED) are considered pre-testicular causes of male subfertility. No previous study systematically evaluated the prevalence of ED and PE along with their possible correlations with clinical and colour-Doppler ultrasound (CDU) features in infertile men.

Methods: Ejaculatory status, erectile function, prostatitis symptoms and psychopathological traits of 244 men complaining of couple infertility were evaluated by Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function-15 (IIEF-15), National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and Middlesex Hospital Questionnaire (MHQ), respectively. PEDT score ≤8 indicates no-PE. IIEF-15 erectile function domain (IIEF-15-EFD) score <26 indicates erectile dysfunction. All patients underwent simultaneous hormone evaluation, seminal analysis and interleukin 8 (sIL8), a reliable surrogate marker of prostatitis, along with penile, scrotal and transrectal CDU, before and after ejaculation.

Results: PE was found in 38 (15.6%) and ED in 43 (17.8%) subjects. After adjusting for age, a positive association between PEDT score and prostatitis symptoms (NIH-CPSI score) and signs (sIL8) was observed. In addition, subjects with a higher PEDT score more often had CDU features suggestive of prostate inflammation, including hypoechoic texture, hyperaemia and a higher arterial peak systolic velocity (APSV). Finally, they showed a higher prevalence of psychopathological traits (MHQ score). In a multivariate model including age and calculated free testosterone (also positively related to PEDT score), APSV, NIH-CPSI and MHQ score were independently positively associated with PEDT score. IIEF-15-EFD score was positively associated with mean arterial blood flow acceleration at basal penile CDU, while a negative association with NIH-CPSI and MHQ score was observed. No correlation between IIEF-15-EFD or PEDT score and semen parameters was observed.

Conclusions: PE and ED should be ruled out in infertile patients. However, they have no impact on semen parameters. PEDT score is positively associated with prostatitis symptoms and signs including CDU features.
