Epidemiology

Epididymitis is a common cause of acute scrotal pain in adolescents and adults.[7] Data on the incidence and prevalence of acute epididymitis are, however, limited. In the US, there are approximately 600,000 cases of epididymitis reported each year.[8]​

One 2005 study in Canada showed that 0.9% of men seen at an outpatient practice over a 2.5-year period presented with epididymitis.[9] In a study in the UK, the reported annual incidence was 2.45 cases per 1000 men between 2003 and 2008.[10] Another study in boys, undertaken in Europe, estimated the annual incidence of epididymitis at 1.2 per 1000 male children.[11]

Epididymitis may present at any age, with the majority of patients aged 20 to 39 years.[12] The majority of cases of epididymitis in children occur around the time of puberty in early adolescence.[13]
