What Does Trichomoniasis Discharge Look Like?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Trichomoniasis discharge is typically yellow-green, frothy, and has a strong fishy odor. This sexually transmitted infection affects up to 3.7 million people in the United States annually. The discharge often appears bubbly or foamy in texture and may be accompanied by itching, burning during urination, or pelvic discomfort. In women, the discharge usually comes from the vagina, while men may experience urethral discharge that's typically clear or white. About 70% of infected individuals show no symptoms initially, making the distinctive discharge an important warning sign. The odor becomes more noticeable after sexual intercourse or during menstruation.
