Trichomoniasis (pronounced trik-uh-muh-NEYE-uh-sis) is a common sexually transmitted infection (STI) caused by a tiny parasite called Trichomonas vaginalis. It affects both men and women, but women are more likely to show symptoms.
What Causes Trichomoniasis?
Trichomoniasis spreads through:
– Unprotected vaginal sex (most common)
– Sharing sex toys without cleaning them-
– Rarely, through genital touching
It does not spread through oral or anal sex, kissing, hugging, or toilet seats.
Symptoms of Trichomoniasis
Many people with trichomoniasis have no symptoms, especially men. But when symptoms appear, they may include:
In Women:
– Foul-smelling, greenish or yellowish vaginal discharge
– Vaginal itching or irritation
– Pain during sex or urination
– Vaginal redness or swelling
In Men:
– Burning after urination or ejaculation
– Discharge from the penis
– Mild itching inside the penis
Why It is a Matters
If left untreated, trichomoniasis can:
– Increase the risk of getting or spreading HIV
– Cause complications in pregnancy, such as preterm delivery or low birth weight
– Lead to discomfort and spread to others through sexual contact
Diagnosis
Trichomoniasis is diagnosed through:
– A physical exam
– Lab tests (urine or swab from genitals)
•Rapid antigen tests (results in less than an hour in some clinics)
Treatment
– Treated with oral antibiotics, usually metronidazole or tinidazole.
– Both partners should be treated at the same time to prevent reinfection.
– Avoid sex for at least 7 days after completing treatment.
Prevention Tips
– Use condoms during vaginal sex
– Limit the number of sexual partners
– Get tested regularly, especially if you’re sexually active
– Avoid sharing sex toys or clean them before and after use
Final Thoughts
Trichomoniasis is curable, but many people don’t realize they have it. Regular testing, safe sex practices, and open communication with partners can help prevent it. If you notice unusual symptoms or think you’ve been exposed, don’t wait—see a doctor for testing and treatment.
