Mycoplasma genitalium infection

Last edited: 4/15/2026

Overview

Mycoplasma genitalium is a sexually transmitted infection contributing to 10-35% of non-chlamydial non-gonococcal urethritis in men and 10-25% of cervicitis and pelvic inflammatory disease in women 1.

Diagnosis

  • Symptoms: Asymptomatic infections common; men present with urethritis, dysuria, discharge; women with vaginal discharge, dysuria, or PID symptoms 1.
  • Testing: Nucleic acid amplification testing (NAAT) required; must include macrolide resistance mutation investigation 1.
  • Management

  • First-line Treatment: Azithromycin (cure rate 85-95% in susceptible infections); extended course may improve efficacy 1.
  • Adjunctive Therapy: Pre-treatment with doxycycline (30-40% cure rate) may reduce organism load and macrolide resistance risk 1.
  • Second-line Therapy: Moxifloxacin for resistant cases 1.
  • Special Populations

  • Pregnancy: Specific recommendations not detailed in provided abstracts 1.
  • Pediatrics: Not addressed in provided abstracts 1.
  • Elderly: Not addressed in provided abstracts 1.
  • Comorbidities: No specific guidance provided for patients with comorbidities 1.
  • Key Recommendations

  • Diagnose M. genitalium using nucleic acid amplification testing, including macrolide resistance mutation detection (Evidence: Strong 1).
  • Initiate treatment with azithromycin for susceptible infections; consider extended courses for improved efficacy (Evidence: Moderate 1).
  • Use doxycycline pre-treatment to potentially reduce organism load and minimize macrolide resistance development (Evidence: Moderate 1).
