Trichomonas (also called “Trich”) is caused by a parasite in the vagina or urethra (the tube or duct through which urine leaves your body). It can be cured with antibiotics. Symptoms usually begin to show 3 to 21 days after infection occurs, especially in girls and women.

Girls, you may have trichomonas if you're experiencing:

  • Change in vaginal discharge (like an increase in the amount you produce or a change in texture [thinner or frothy]; the discharge may also have a musty/fishy smell)
  • Soreness, itching, and inflammation in and around the vagina
  • Pain when peeing
  • Pain when having sex
  • It is possible to have not symptoms, get tested.

Most males with trichomonas have no signs or symptoms. But you may have trichomonas if you have irritation or pain inside your penis, a mild discharge or slight burning after you pee or ejaculate.

For men, there is no way to test if you have trichomonas. It is important for females who test positive for Trichomonas to tell their male partners to come in and get treated.

Protect yourself against trichomonas by using condoms and dental dams. Tell your partner if you have trichomonas so they can get tested and treated.
