Trichomoniasis

Trichomoniasis is an STI caused by a tiny parasite called Trichomonas vaginalis (TV). It can be easily passed on through sex and most people don't know they're infected.

In women, trichomoniasis can cause a frothy yellow or watery vaginal discharge that has an unpleasant smell, soreness or itching around the vagina, and pain when passing urine.

In men, trichomoniasis rarely causes symptoms. You may experience pain or burning after passing urine, a whitish discharge, or an inflamed foreskin.

Trichomoniasis can sometimes be difficult to diagnose and your GP may suggest you go to a specialist clinic for a urine or swab test. Once diagnosed, it can usually be treated with antibiotics.

If you have no symptoms and want a straightforward test you can:

  • either order a smart kit online for home delivery
  • or attend one of our clinics where you can collect a smart kit without needing to wait and see a clinician.

This is a quick, easy and confidential way to screen for chlamydia, gonorrhoea, HIV and syphilis.
