Correct answer: AOfloxacin 200 mg BD for 14 days

In heterosexual men, particularly those >35 years or with urological risk factors, enteric Gram-negative organisms (E. coli) are the most common cause of epididymo-orchitis. A fluoroquinolone with good urinary tract and prostatic penetration (Ofloxacin 200 mg BD for 14 days) is the recommended treatment per BASHH. This differs from sexually acquired epididymo-orchitis in younger MSM where Chlamydia is more common and Doxycycline is preferred.
