Trichomonas infection is often called “trich.” It's caused by a parasite that is passed during sex. This makes trich a sexually transmitted infection (STI). An STI is sometimes called a sexually transmitted disease (STD). Both men and women can get trich, but it more commonly causes complications in women.
Most people who have trich don't have any symptoms at first. Symptoms in men are not very common. If symptoms do occur, they may take weeks or months to develop. Men may have trich and pass it to women during sex without knowing they were ever infected.
Symptoms in men can include:
- Itching or sore feeling inside your penis
- Fluid or frothy discharge from your penis
- Needing to urinate often
- Burning after urinating
- Burning after ejaculating
Trich is most often treated with antibiotics. Without treatment, trich can increase the risk of more serious health problems, such as HIV and certain other STIs.
Trich passed on to a female partner and not treated can lead to problems, such as:
- Pelvic inflammatory disease
- Preterm delivery. This means giving birth to a baby early if you're pregnant.
