By Medically reviewed by hellodoktor


What is Mycoplasma Genitalium STD?

Mycoplasma genitalium (MG) was first identified in the early 1980s. It is a type of bacteria that can cause an STD. MG speads through sexual interactions. Even without actual intercourse/vaginal sex, it can still spread via touching and rubbing.

MG can cause a number of complications:

  • A problem that makes your urethra irritated, swollen, and itchy, called urethritis. It can happen to men and women.
  • An infection of a woman’s reproductive organs, called pelvic inflammatory disease (PID), which can make it hard to get pregnant.
  • An inflamed cervix, called cervicitis
  • Scientists aren’t sure if an MG infection can make it hard for men to get a woman pregnant.

How common is Mycoplasma Genitalium STD?

A recent study showed that more than 1 in 100 adults might have it. Please discuss with your doctor for further information.


What are the symptoms of Mycoplasma Genitalium STD?

MG doesn’t always cause symptoms, so it’s possible to have it and not know it.

In men, the symptoms are:

  • Watery discharge from your penis
  • Burning, stinging, or pain when you pee

The symptoms for women are:

  • Discharge from your vagina
  • Pain during sex
  • Bleeding after sex
  • Bleeding between periods
  • Pain in your pelvic area below your belly button

There may be some symptoms not listed above. If you have any concerns about a symptom, please consult your doctor.

Diagnosis & treatment

How is Mycoplasma Genitalium STD diagnosed?

Unlike other STDs, there is no test for MG that the FDA has approved. But if you or your doctor think you might have it, you can get a nucleic acid amplification test (NAAT).

For this test, you might have to give a sample of your pee. Your doctor might also use a swab to take a sample from your vagina, cervix, or urethra, the tube that carries your pee out of your body.

How is Mycoplasma Genitalium STD treated?

MG can be a tricky problem to treat. Common antibiotics like penicillin kill bacteria by damaging a germ’s cell walls. But MG bacteria don’t have cell walls, so these drugs don’t work very well.

Your doctor might try azithromycin (Zithromax, Zmax) first. If that doesn’t work, your doctor might give you moxifloxacin (Avelox).

After a month, you can get another test to make sure the infection is gone, but it’s not a good idea to get routine tests if you don’t have symptoms from MG. If you still have symptoms and you still have the disease, you’ll need to get more treatment.

Your doctor might also focus on treating the other conditions MG can cause, like urethritis, PID, or cervicitis.

Your sex partners should talk to their doctors about getting tested and treated and so they don’t infect other people or give it back to you. You can still get MG again even when you’ve already had treatment for it.

Lifestyle changes & home remedies

What are some lifestyle changes or home remedies that can help me manage Mycoplasma Genitalium STD?

The following lifestyles and home remedies might help you cope with Mycoplasma Genitalium STD:

Condoms can reduce your chance of getting MG, but they can’t guarantee you won’t get it. If you have the disease, avoid having sex for 7 days after you start treatment so you don’t infect others.

If you have any questions, please consult with your doctor to better understand the best solution for you.
