What is it?
Mycoplasma genitalium (MG) is a sexually transmissible infection. It is similar to, but less common than Chlamydia.  There are currently no recommendations to include routine testing for MG in people who have no symptoms and it is advised that testing is limited to those with symptoms or contacts of those with known MG infection only.

If symptomatic MG is left untreated it can cause health problems by spreading to the uterus (womb) and fallopian tubes causing an infection of that area called pelvic inflammatory disease (PID). PID can cause infertility.

How is MG transmitted?
MG is transmitted by having unprotected anal or vaginal sex.  Unprotected means sex without a condom. Some people may not have any symptoms, but can still pass on the infection

What are the symptoms of MG?
While MG often has no symptoms, if symptoms do occur they can include:

In women:

  • Lower abdominal pain/discomfort
  • Pain while having sex
  • Unusual vaginal bleeding (between periods and after sex)
  • Unusual vaginal discharge
  • Pain on passing urine

In men:

  • Discharge from the penis
  • Pain on passing urine

Testing for MG
MG is not routinely tested for.  If testing is required samples are collected from urine or from a vaginal swab. 

The best treatment option for MG is still unclear. If MG is suspected then oral antibiotics are used.
If symptoms were present a follow up test is done after one month if symptoms persist.
A repeat test is usually advised 3 months later to make sure that there has been no reinfection.
All sexual partners over the past six months should also be contacted and treated.

Preventing MG infection
As with other sexually transmissible infections the best way to prevent MG is by using condoms correctly when having sex. For useful tips on condom use check out our condom fact sheet.
