Many women and most men do not have any symptoms of trich. But if there are symptoms, they usually start within 1 week after infection. In some cases, it can take 1 to 6 months for symptoms to start.
In women, symptoms include a greenish-yellow, frothy vaginal discharge with a different odour, vaginal itching, and pain during urination or sex.
In men, symptoms include discharge from the penis, irritation at the tip of the penis, and a burning feeling during urination.
