Tuberculous epididymo-orchitis

Last edited: 4/10/2026

Overview

Tuberculous epididymo-orchitis is an inflammation of the epididymis and testis caused by Mycobacterium tuberculosis. It is a less common cause of epididymo-orchitis, particularly in developed countries, but should be considered in endemic areas or in individuals with risk factors for tuberculosis 1.

Diagnosis

  • Objective swelling and tenderness on testicular examination should prompt empirical treatment 1.
  • Diagnostic tests include microscopy, culture, and nucleic acid amplification tests (NAATs) for Mycobacterium tuberculosis* 1.

    Management

  • Empirical treatment should be initiated in patients with objective swelling and tenderness on testicular examination 1.
  • First-line empirical treatment for sexually acquired epididymo-orchitis is ceftriaxone 1g intramuscularly and doxycycline 1.
  • Higher doses of ceftriaxone are recommended to ensure effective treatment of strains with reduced susceptibility 1.
  • Ofloxacin or doxycycline is recommended for patients with epididymo-orchitis likely due to non-gonococcal organisms (e.g., negative Gram stain for intracellular diplococci or no risk factors for gonorrhea) 1.
  • Key Recommendations

  • Empirical treatment should be started in patients with objective swelling and tenderness on testicular examination 1. (Evidence: Expert opinion)
  • First-line empirical treatment for sexually acquired epididymo-orchitis has changed to ceftriaxone 1g intramuscularly and doxycycline 1. (Evidence: Expert opinion)
  • Higher dose of ceftriaxone in line with the BASHH 2018 gonorrhoea guideline ensures effective treatment of strains with reduced susceptibility 1. (Evidence: Expert opinion)
