What Is Mycoplasma Genitalium (Mgen)?

Mycoplasma genitalium (Mgen) is a sexually transmitted bacterium that can infect the urinary and reproductive tracts in both men and women.

It belongs to the broader group of Mycoplasma bacteria, which are atypical in that they lack a cell wall. This structural difference makes them naturally resistant to certain antibiotics such as penicillin.

While Mgen is specifically linked to sexual transmission, other species in the same group, such as Mycoplasma pneumoniae, are not sexually transmitted and are more commonly associated with respiratory tract infections like atypical pneumonia.

Mgen does not usually go away on its own and typically requires medical treatment to clear the infection. If left untreated, it can be passed to sexual partners and may lead to complications, particularly in women.

How Is Mycoplasma Genitalium Transmitted?

Mgen is transmitted primarily through unprotected sexual contact, including vaginal, anal, and possibly oral sex.

The bacteria can spread through bodily fluids and may infect the urethra, cervix, or rectum. It can also be passed from one person to another even when no symptoms are present, making it difficult to detect without proper screening.

Mycoplasma Genitalium Symptoms & Complications

Many people with Mgen do not experience noticeable symptoms. When symptoms do occur, they can differ between men and women.

These symptoms are non-specific and often resemble those caused by other sexually transmitted infections (STIs), such as chlamydia or gonorrhoea, which makes precise diagnosis important.

If left untreated, Mgen can lead to serious health complications, particularly in women.

Men Women
Symptoms
  • Pain or burning during urination
  • Discharge from the urethra
  • Irritation or discomfort in the penis
  • Unusual vaginal discharge
  • Pain or burning during urination
  • Bleeding between periods or after sex
  • Pelvic discomfort or pain
Complications
  • Urethritis
  • Epididymitis (inflammation of the tube behind the testicles)
  • Pelvic inflammatory disease (PID)
  • Infertility caused by damage to the fallopian tubes
  • Chronic pelvic pain
  • Increased risk of ectopic pregnancy

Mycoplasma Genitalium Testing & Diagnosis

Diagnosis of Mgen typically involves testing a urine sample or a swab from the genital area using a nucleic acid amplification test (NAAT), which detects the bacterium’s genetic material.

Testing may be recommended if you have ongoing symptoms of a sexually transmitted infection, especially if other common infections such as chlamydia or gonorrhoea have been ruled out.

Mycoplasma Genitalium Treatment

Treatment for Mgen generally involves a course of antibiotics, although antibiotic resistance is a growing concern.

The treatment plan may involve more than one type of antibiotic and is often adjusted based on the strain’s resistance pattern and how well the initial treatment works.

Because resistant strains are increasingly common, your doctor may recommend follow-up testing or resistance testing to guide further management.

It is important to take the full course of medication, even if your symptoms improve, and to return for follow-up testing to make sure the infection has been successfully treated.

Mycoplasma Genitalium Prevention

You can reduce your risk of Mgen by taking preventive steps such as:

  • Using condoms consistently during all types of sexual activity.
  • Limiting the number of sexual partners.
  • Avoiding sexual contact with someone who has symptoms of a STI.
  • Getting tested regularly if you are sexually active, especially with new or multiple partners.
  • Being open with your partner about STI testing to help reduce the risk of transmission.

There is currently no vaccine for Mgen, so these preventive behaviours play an important role in lowering your risk.

Frequently Asked Questions (FAQ)

Mycoplasma genitalium may remain contagious until the infection is fully cleared, which is why follow-up testing is often recommended after treatment. Although antibiotics are used to eliminate the infection, resistant strains can persist and continue to spread. Your doctor may advise post-treatment testing to confirm that the infection has been fully cleared before resuming sexual activity.
In Chinese, Mycoplasma is commonly referred to as “支原体” (zhī yuán tǐ), a term that covers the entire genus of Mycoplasma bacteria. Mycoplasma genitalium, the sexually transmitted species, is often written as “解脲支原体” (jiě niào zhī yuán tǐ) or simply referred to under the broader category depending on context.
Mycoplasma genitalium is considered contagious and can be transmitted through unprotected sexual contact, even in the absence of symptoms. The likelihood of transmission can vary depending on the site of infection, type of sexual activity, and presence of resistant strains. It is advisable to consult a doctor if you suspect exposure, particularly when symptoms persist or other sexually transmitted infections have been ruled out.
Mycoplasma genitalium does not usually go away on its own and often requires antibiotic treatment to fully clear the infection. Without treatment, the bacteria can persist in the body, potentially leading to complications or ongoing transmission. It is advisable to consult a doctor for proper testing if you suspect exposure or are experiencing symptoms.
Mycoplasma genitalium can remain in the body without causing symptoms, which may seem like a dormant state, but the infection is still active and transmissible. Its ability to evade the immune system may lead to persistent or low-grade infections. It is advisable to consult a doctor if you suspect exposure or are experiencing symptoms, as proper testing is needed for diagnosis.
Mycoplasma genitalium is transmitted primarily through unprotected sexual contact, including vaginal, anal, and possibly oral sex. It spreads through sexual fluids and can be passed between partners even when no symptoms are present. Using protection consistently and correctly, along with regular testing, can help reduce the risk of transmission.
The incubation period for Mycoplasma genitalium is not clearly defined but is generally estimated to range from one to five weeks. During this time, symptoms may be absent while the infection remains transmissible. If you suspect exposure and are unsure when to test, it is advisable to consult a doctor for appropriate guidance.
Yes, Mycoplasma genitalium is a sexually transmitted infection (STI) that is primarily spread through sexual contact, including vaginal, anal, and possibly oral sex. Although many people with the infection do not experience symptoms, it can still be transmitted and may lead to complications if left untreated.
If left untreated in men, Mycoplasma genitalium may cause persistent or recurrent urethritis, epididymitis, and potentially increase the risk of sexually acquired reactive arthritis. As the infection can also be transmitted to partners, timely diagnosis and treatment are important. It is advisable to consult a doctor if symptoms persist or return after treatment.
Mycoplasma genitalium is primarily transmitted through unprotected sexual contact, which means your partner may have acquired it from previous or current sexual activity. Because the infection often causes no symptoms, it can unknowingly be passed between partners. It is advisable to consult a doctor if you or your partner suspect exposure or are experiencing symptoms, as proper testing and treatment may be required.
Mycoplasma genitalium is a significant sexually transmitted infection due to its ability to cause complications and its growing resistance to antibiotics. While some infections remain asymptomatic, untreated Mgen can lead to conditions such as urethritis, pelvic inflammatory disease, and infertility.
It is unlikely to contract Mycoplasma genitalium from kissing, as the infection is primarily transmitted through unprotected vaginal, anal, or possibly oral sex. It is not typically spread through saliva or casual contact. If you are concerned about possible exposure, it is advisable to consult a doctor for appropriate testing and guidance.
Mycoplasma genitalium is difficult to treat due to its natural resistance to common antibiotics and its ability to develop further resistance. Treatment often requires specific antibiotics and may involve follow-up testing.
The only way to confirm a Mycoplasma genitalium infection is through a nucleic acid amplification test (NAAT), usually using a urine sample or genital swab. Since many cases have mild or no symptoms, it is advisable to consult a doctor for testing if you have persistent symptoms or may have been exposed to a sexually transmitted infection.
