Abstract
Summary
Both erectile dysfunction (ED) and herpes simplex virus (HSV) infections are related to cardiovascular events. However, the relationship between ED and HSV infections remains undetermined. The aim of our study was to investigate the possible influence of HSV infections on the development of ED using the Taiwan National Health Insurance database. We identified patients with HSV type 1 or type 2 infections from the 1 000 000 sampling cohort data set. Male patients of age 18 years or older who had been diagnosed as cases of HSV infection since January 1, 2001 were enroled. Patients with previous history of stroke, spinal cord injury or malignancy were excluded. A control group was selected, comprising male patients without HSV infection, stroke, spinal cord injury or malignancy. The age, time of enrolment and comorbidities were matched in the two groups. A total of 1 717 HSV subjects (mean age 43.29 ± 15.97 years) and 6 864 control subjects were enroled. During an average of 3.91 ± 1.93 years' follow‐up, HSV‐infected subjects experienced a higher incidence of ED than control subjects (1.7% vs. 0.7%, respectively). The log‐rank test showed that patients with HSV infections had a significantly higher incidence of ED than those without HSV infections (p p < 0.001). In conclusion, HSV infections were associated with risk of ED in this cohort.
