untreated trichomoniasis

The parasite Trichomonas vaginalis causes Trichomoniasis, the prevalent STI. It can affect both men and women.

Trichomoniasis symptoms can include itching, irritation, and abnormal discharge.

However, most individuals with Trichomoniasis do not show any symptoms, making them unaware of the need for treatment.

Trichomoniasis can lead to various complications if left untreated.

This article aims to unravel the consequences and solutions of this common yet often neglected Sexually Transmitted Infection.

What happens if Trichomoniasis is left untreated

If left untreated, Trichomoniasis symptoms can escalate, leading to discomfort during sex, genital itching, and abnormal discharge. 

However, many carriers remain asymptomatic, unknowingly spreading the infection.

An estimated 3% of the US population is thought to carry T. vaginalis infection.

Untreated Trichomoniasis can lead to various long-term effects, some of which have been discussed below.

Increased risk of acquiring other STIs

Trichomoniasis increases the risk of acquiring STIs, especially HIV.

Women with Trichomoniasis and HIV are more likely to pass both diseases on to their partners.

Trichomoniasis can disrupt the mechanical barrier provided by the vaginal mucosa, making it easier for HIV to enter the body.

It can also impair the immune response, making the body less able to fight off HIV infections.

Therefore, it is essential to address and treat Trichomoniasis to help reduce the risk of HIV transmission and acquisition.

Pelvic Inflammatory Disease (PID)

The connection between untreated Trichomoniasis and Pelvic Inflammatory Disease (PID) is not fully understood, but there is evidence of an association. 

Trichomonas vaginalis can get into the upper urinary system and cause Pelvic Inflammatory Disease if it is not treated. 

One study found that T. vaginalis was present in about 13% of people with PID. 

However, it’s important to note that Trichomonas is not known to cause PID directly.

The exact nature of the connection between Trichomoniasis and PID is still being studied, and further research is needed to understand this relationship’s implications fully.

Furthermore, people who had Trichomoniasis were twice as likely to have Endometritis, a disease in which the lining of the womb becomes swollen and itchy. 


Untreated Trichomoniasis can lead to infertility in both men and women. 

In women, the infection can induce inflammation in the reproductive organs, which can cause scarring and damage, making pregnancy more difficult.

Untreated Trichomoniasis in males can cause Urethritis, Prostatitis, and Epididymitis, which can negatively affect male fertility.

Furthermore, Trichomonas vaginalis can reduce sperm motility, further impacting male fertility.\

Trich can lead to chronic genital discomfort and pain during intercourse. Don’t forget to practice safe sex to prevent contracting the infection.

Adverse birth outcomes

Untreated Trichomoniasis in pregnant women can lead to adverse birth outcomes.

These include preterm delivery, pre-labor rupture of membranes, and low birth weight.

Trichomoniasis can cause inflammation in the reproductive organs, leading to tubal damage and making it more difficult to become pregnant.

Additionally, perinatal transmission of T. vaginalis can occur, leading to vaginal and respiratory infections in newborns.

Cervical or prostate cancer

Because it causes chronic inflammation, Trichomoniasis can lead to cancer of the cervix or prostate if it is not addressed. 

Trichomonas vaginalis infection has been associated with an increased risk of cervical carcinogenesis. 

The infection can contribute to the development of Cervical cancer by causing inflammation, abruption of the cervical epithelium, and influencing the immune system to eliminate HPV.

However, it’s important to note that there is still some ambiguity and controversy regarding the relationship between Trichomoniasis and Cervical cancer.

Trichomoniasis can make the prostate swell, which makes them more likely to get Prostate Cancer and Benign Prostatic Hyperplasia (BPH).

How is Trichomoniasis diagnosed and treated

Trichomonas can be diagnosed through a physical examination of the genitals and laboratory tests, such as swabs, urine tests, or cell cultures.

A short course of antibiotics prescribed by a doctor can effectively treat Trichomoniasis.

The most common antibiotics prescribed for this purpose are Metronidazole and Tinidazole.

It is essential to complete the entire course of antibiotics and avoid having sex until the infection is treated.

Treating both partners simultaneously is crucial to prevent reinfection.

Regular testing post-treatment ensures complete eradication of the infection.


Untreated Trichomoniasis can have serious consequences.

These include long-lasting infections, adverse birth outcomes, PID, and an increased risk of HIV transmission.

A physical examination of the genitals and laboratory testing, such as swabs, urine tests, or cell cultures, can be used to diagnose Trichomonas.

Trichomoniasis can be successfully treated with antimicrobial medications such as Metronidazole or Tinidazole, which are available by prescription.

Consult a medical professional for a better understanding of the repercussions of untreated Trichomoniasis. 

Frequently Asked Questions

How long does Trichomoniasis last untreated?

Trichomoniasis can be treated with antibiotics. Untreated Trichomoniasis can persist for an extended period. However, the duration can vary among individuals. If left untreated, it may last from months to years, potentially leading to chronic symptoms and increasing the risk of HIV and spreading the infection to others.

Can Trichomoniasis go away on its own?

No, Trichomoniasis does not typically resolve on its own. It can last for months or even years if not treated, and the infected individual can continue to carry the infection to their sexual partners. Seeking treatment is crucial to address the infection and prevent potential complications effectively.

Is Trichomoniasis preventable?

Yes, Trichomoniasis is preventable. The most effective way to prevent it is by practicing safe sex, which includes using condoms during sexual activity, avoiding sharing sex toys, and getting tested and treated if you or your partner have any symptoms or have been exposed to the infection.

Can Trichomoniasis be transmitted through non-sexual means?

Trichomoniasis doesn’t usually transmit through non-sexual means except through the sharing of unwashed or unprotected sex toys and transmission from a pregnant mother to her baby during delivery. Trichomoniasis is an STI, and its transmission emphasizes the importance of safe sex practices to reduce the risk of infection.
