Mycoplasma genitalium (Mgen)

Mycoplasma genitalium is a curable sexually transmitted infection caused by bacteria. It is sometimes called “Mgen” for short.

Many people who have have Mgen will not develop any problems and will clear the infection naturally without needing any treatment.

Mgen is a bacterium that is passed from one person to another during sex.

The bacteria infect the cells lining the cervix (neck of the womb), urethra (tube where urine comes out) or rectum (back passage).

It cannot be caught by kissing, hugging, sharing towels, swimming pools or toilet seats.

Mycoplasma genitalium may cause:

• pain in the lower abdomen (tummy)
• pain during sex in women or trans men
• vaginal bleeding after sex
• pain or burning in the penis when passing urine
• discharge from the penis

Testing for Mgen is not recommended for everyone. A test may be recommended if you have certain symptoms. Our nurses or doctors will be able to advise you.

Mgen tests can be done on a urine sample or swabs taken from the genitals (penis or vagina) or rectum (back passage).

If you are diagnosed with Mgen, we recommend you are tested for other STIs.

Mycoplasma genitalium is treated with antibiotics.

All Umbrella clinics provide treatment for sexually transmitted infections, including Mgen.

A test of cure is recommended at least four weeks after the treatment.

As Mgen is sexually transmitted, it’s important that your current partner(s) is/are tested for the infection too so they can be treated if needed.

You and your partner(s) should not have sex until you and they have finished treatment and have no symptoms.
