Mycoplasma Genitalium (Mgen)
Last updated: Jul 25, 2025
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.

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.
