The relevance of Chlamydia trachomatis in acute epididymitis in young men

Young men presenting to a General Surgical Unit with acute epididymitis underwent microbiological investigation, including culture for Chlamydia trachomatis. The results were compared with similar investigations in an asymptomatic control population and with patients presenting to the Department of Genito-urinary Medicine with urethral discharge. Chlamydia trachomatis was cultured from 15% of patients with acute epididymitis and a further 15% had serological evidence of exposure to Chlamydia. Nearly 50% of patients attending the Genito-urinary clinic grew Chlamydia from the urethra. The background prevalence of Chlamydia in the control population was low. It is necessary to identify the significant minority of young men with acute epididymitis associated with chlamydial infection, because of the risk of pelvic inflammation and infertility in their female partners. At present this can only be achieved by submitting all young men with acute epididymitis to full microbiological investigation.
