What is Trichomoniasis?

Trichomoniasis is an STD that is caused by the parasite Trichomonas vaginalis. This STD is not often tested for immediately at the GP or local GGD unless you are negative for other, more common, STDs. Its symptoms vary between individuals, but in most cases they are limited. However, while Trichomoniasis is the most common non-viral STD worldwide, it is not the most diagnosed due to the lack of symptoms and testing. Trichomoniasis often goes unnoticed, but reduces your immunity, making you more prone to contracting other, more serious STDs.

How do I get Trichomoniasis?

Trichomoniasis can be transmitted through unprotected sexual contact and can cause an infection in a woman's genital tract (vulva, vagina, cervix, urethra) and a man's penis and urethra. Trichomoniasis can be transmitted through vaginal penetration, vagina on vagina, and fingering. There is an 80% chance of contracting Trichomoniasis when having unprotected sex with someone with the STD. Besides transmission through sex, it is possible to get infected by objects that have been contaminated by an infected person such as sex toys, a toilet seat, or a towel.

Do I have Trichomoniasis?

The majority of people who contract Trichomoniasis show no symptoms and may remain asymptomatic throughout the entire infection. Generally, women experience symptoms more often than men, and about 20% to 50% of infected women develop symptoms at some point during the infection. But even if they do, these symptoms can arise years after being infected. As symptoms are mild and often limited, individuals are often not tested for Trichomoniasis. However, even without symptoms you can still be infected and transmit it to your sexual partner(s). Below are gender-specific symptoms for Trichomoniasis.

Symptoms in men include:

  • Abnormal discharge from the penis
  • Inflammation of the glans and/or skin of the penis
  • Pain / burning sensation while urinating

Symptoms in women include:

  • Red, inflamed, and/or painful vagina
  • Itching of the vagina
  • Change in vaginal odor (often described as fishy smell)
  • Yellow-green vaginal fluid (possibly foamy)
  • Pain / burning sensation while urinating

What are the risks?

Over het algemeen zijn de langetermijngevolgen van een Trichomonas-infectie niet extreem gevaarlijk. Vooral bij vrouwen kan het voor ongemakken zorgen, maar dat is vooral als zij symptomen ervaren.

When should I get tested?

Trichomoniasis has an incubation period of 4-28 days. This means that before this time the bacteria are often not detectable yet. In case you are experiencing symptoms we recommend waiting for 4 days before getting tested. In case you are not experiencing symptoms we recommend waiting longer: at least 28 days. When you get tested too early it's possible the test will come back negative, even if you are infected. Therefore it's important to wait the recommended period before getting tested.


Trichomoniasis can easily be treated using antibiotics, which can be taken orally. At How Are You Diagnostics we provide you with an certificate with the test result, which can be downloaded from our result portal. In case you test positive for Trichomoniasis you can download the certificate to show to your GP. This prevents getting retested at the GP.
