Symptoms of Trichomoniasis

Introduction

Trichomoniasis is a common, treatable sexually transmitted infection (STI) caused by the protozoan parasite Trichomonas vaginalis. This page provides comprehensive information on trichomoniasis, including symptoms, treatment options, and prevention strategies.

What is Trichomoniasis?

Trichomoniasis, often referred to as “trich,” is a very common STI. Although symptoms vary, most people infected with trich do not realize they have it.

Symptoms of Trichomoniasis

In Men:

  • Itching or irritation inside the penis
  • Burning after urination or ejaculation
  • Discharge from the penis

In Women:

  • Itching, burning, redness, or soreness of the genitals
  • Discomfort during urination
  • Clear, white, yellowish, or greenish vaginal discharge with a fishy smell

Symptoms can range from mild irritation to severe inflammation and can appear within 5 to 28 days after infection.

Complications

Trichomoniasis can increase the risk of contracting or spreading other STIs, including HIV. In pregnant women, it can lead to premature birth or low birth weight babies.

Transmission

Trichomoniasis spreads through sexual contact with an infected person, including vaginal, oral, and anal sex. The infection can occur even without visible symptoms.

Diagnosis

Diagnosis involves:

  • Physical examination of sores
  • Laboratory tests such as PCR to detect viral DNA
  • Blood tests for HSV antibodies
