Mycoplasma genitalium (MG)

Mycoplasma genitalium (MG) is a bacterial infection of the urinary or genital tracts.

Transmission: Unprotected vaginal or anal sex

Symptoms: Many people will not have any symptoms and the infection will clear itself naturally. Others may have one or more symptoms such as:

Symptoms in people with a penis:

  • Pain when urinating
  • Discharge
  • Pain in testicles
  • Inflammation in the rectum causing anal pain/discharge

Symptoms in people with a vagina:

  • Discharge
  • Pain in lower abdomen
  • Abnormal vaginal bleeding – such as in between periods or after sex
  • Pelvic Inflammatory Disease (PID)

Testing: Sexual health clinics do not test for mycoplasma genitalium routinely, and you are likely only going to be tested if you have symptoms.

It is tested by a swab from the tip of the penis and a urine test, or a swab from inside the vagina

Treatment: A course of antibiotics
