How can Gardnerella be detected in men after years without sexual activity? (Latency explained)

Hello, this is Dr. Changki Lee from Goldman Urology Clinic, Incheon.

It is understandable to feel confused when Gardnerella is detected despite no recent sexual activity.

Gardnerella is commonly associated with bacterial vaginosis in women, but it can also be found in men. Importantly, it is not strictly classified as a typical sexually transmitted infection, as it can behave like part of the normal microbial flora (commensal bacteria).

In men, Gardnerella may persist in small amounts within the urethra or prostate, especially if conditions such as changes in the local environment, decreased immunity, or urinary flow issues allow the bacteria to remain or multiply.

Even after a long period without sexual activity, it is possible that the bacteria were previously present at low levels (latent colonization) and were only detected during a detailed test like PCR.

In most cases, Gardnerella does not cause serious problems in men. However, if it is associated with symptoms such as urethral discomfort or prostatitis, further evaluation and treatment may be necessary.

We recommend visiting a urology clinic for a comprehensive assessment based on your current condition.

At our clinic, we carefully assess each patient’s condition and provide accurate diagnosis and personalized treatment plans.

Identifying the cause is the first step toward effective treatment.

If symptoms persist, medical evaluation is recommended.

Thank you, and we hope this information was helpful.
