STD awareness is on its way up, but knowledge of some types of STDs still remains low. Have you ever heard of Trichomoniasis, Mycoplasma or Ureaplasma? Despite being some of the most common types of STDs worldwide, you have probably never heard of these three types of STDs. LetsGetChecked tell you everything you need to know.

Some STDs are still under-reported. Researchers have found that knowledge of STDs and effective contraception is one of the best ways to ensure good sexual health. Recent statistics from the US showed that states that taught abstinence in schools had the highest positivity rates for STIs.


What Is Trichomoniasis?

This STI is caused by the bacteria Trichomoniasis Vaginalis, which can infect both men and women. Women are more likely to display symptoms than men. Symptoms usually appear after 5-28 days of infection. About 3.7 million Americans are infected with Trichomoniasis, but only 30% of these people will experience symptoms, according to the American Centre for Disease Control (CDC).

Signs and symptoms may include:

  • a frothy, yellow-green vaginal discharge that has an odour
  • discomfort passing urine
  • irritation and itching in the genital area
  • discomfort during sexual intercourse
  • may have no symptoms

Treatment: Antibiotics.


What Is Ureaplasma?

While many might not have heard of Ureaplasma, the STI has been found in up to 70% of sexually active adults and can be transmitted sexually. It is caused by the tiny bacteria Ureaplasma urealytica, which can be found in the urinary and genital tract.

Most people have no symptoms, and if they do, the symptoms are usually localised and similar to those associated with urethritis (inflammation of the urethra).

Symptoms in women may include:

  • abnormal vaginal discharge
  • vulval pain during sex or at beginning of penetration
  • pain passing urine
  • abdominal discomfort/pelvic pressure

Symptoms in men may include:

  • urethral discharge: clear, white, yellow, green or with traces of blood
  • pain passing urine
  • itching
  • discomfort in the penis or pubic area
  • pain in the testicles

Treatment: As this is not a bacterium that is routinely tested for, treatment is not absolutely necessary unless the patient is having genitourinary symptoms and all other infections have been ruled out, except for ureaplasma. The standard treatment is a dose of antibiotics, but a longer treatment might be necessary as resistance can be an issue.


What Is Mycoplasma?


Mycoplasma genitalium is a bacteria found in the urinary tract that can be sexually transmitted. In the last few years, more genitourinary clinics have started testing for the bacteria. It is also being recognized as a sexually transmitted infection. A recent study found that the bacteria is present in about 1% of sexually active people. None of the people in the study who had never had sex tested positive for Mycoplasma.

Symptoms in women may include:

  • green, yellow or white vaginal discharge
  • abnormal bleeding
  • pain during sex
  • abdominal discomfort

Symptoms in men may include:

  • urethral discharge: clear, white, yellow or green (urethritis)
  • pain when passing urine
  • discomfort in the penis or pubic area
  • pain in the testicles

Treatment: Mycoplasma is usually treated with antibiotics.
