Evaluating the effect of sleep quality and chronotype differences on erectile dysfunction

İngilizce (OpenAlex)

OBJECTIVE: Erectile dysfunction (ED) refers to an inability to achieve or maintain a firm penile erection sufficient for satisfactory sexual intercourse. Insufficient, irregular sleep and sleep disorders adversely affect human health, including sexual function. Significant differences between biological rhythms (chronotypes) have been reported. In the present study we examine the effect of sleep quality and chronotype differences on ED patients and a control group. PATIENTS AND METHODS: The study included 69 patients who presented with ED and 64 healthy controls. The respondents completed a sociodemographic data form, and disease severity in the ED group was measured using the International Index of Erectile Function (IIEF). The participants were further administered the Hospital Anxiety and Depression Scale (HADS), Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI) and Morningness-Eveningness Questionnaire (MEQ), and the scale scores were compared statistically between the patient and control groups. RESULTS: There was no difference in the age, body mass index (BMI), alcohol use and smoking of the ED and healthy control groups, while the IIEF score was significantly lower in the ED group than in the control group. The PSQI subscale scores other than for sleep duration subscale, the PSQI global score and the HADS score were higher in the ED group than in the control group, while there was no difference between the groups in the MEQ and ISI scores. The IIEF score was correlated with the PSQI and HADS scores, and the PSQI score with the ISI and HADS scores. CONCLUSIONS: It would be useful to evaluate sleep quality in addition to anxiety and depression while evaluating patients with ED. Our study found no relationship between chronotype differences and ED.
