Quick Answer

Yes. A man can carry Trichomonas vaginalis and pass it to partners even when he has no symptoms at all. Most infections in men are silent or cause only mild irritation, and the parasite can live in the urethra or prostate for weeks to months. Testing and treatment with metronidazole or tinidazole cures the infection and stops onward spread.

  • Men usually have no symptoms, so they can carry and transmit the parasite unknowingly.
  • Trichomoniasis is caused by a parasite, not a bacterium or virus, and it is curable.
  • The parasite lives in the urethra and can persist there for weeks or longer.
  • CDC advises treating sexual partners of anyone diagnosed, even if they feel well.
  • A course of metronidazole or tinidazole usually clears the infection.
  • Reinfection is common when partners are not treated at the same time.

The word carrier fits trichomoniasis better than it fits most infections, and the reason is anatomical. The parasite, Trichomonas vaginalis, attaches to the flat, squamous cells that line the lower urogenital tract. In women that lining covers a large surface, so infection often produces discharge, odor, and irritation. In men, the same cells line a much smaller area - mainly the urethra - and the resulting inflammation is easy to miss. A man may notice nothing, or a brief burning sensation he dismisses as nothing important. Because symptoms fade or never appear, many men never seek testing, which is exactly how the parasite keeps circulating between partners.
