Can men get trichomoniasis?

Yes, men can get trichomoniasis, though they are less likely to develop symptoms. Men can carry and transmit the parasite without knowing, making partner testing important.

What does trichomoniasis discharge look like?

In women, trichomoniasis typically causes a frothy, yellow-green vaginal discharge with a strong, unpleasant (often fishy) odour. In men, discharge is usually thin and whitish.

Can trichomoniasis come back after treatment?

Reinfection is common if partners are not treated simultaneously. Both partners must complete treatment and avoid sex for 7 days after treatment to prevent reinfection.
