Mycoplasma genitalium is a lesser known STI but is very common. It has similarities to both chlamydia and gonorrhoea. Most infections of mycoplasma genitalium do not show any symptoms and therefore, it is difficult to know if you have it without being tested.

As mycoplasma genitalium frequently occurs together with other STIs, it can be difficult to diagnose without being tested comprehensively. Studies have indicated that it is prevalent in 1% of the U.S adolescent population.

Mycoplasma genitalium is passed on through unprotected sexual contact. This can be through vaginal, anal and oral sex.

Like most STIs, mycoplasma genitalium can lead to other, more serious conditions. It is the main cause of nongonococcal urethritis in men – chlamydia can also cause this. Mycoplasma genitalium is the bacterium that has been found in association with bacterial vaginosis in women. The long term complications are very similar to chlamydia and gonorrhoea, including pelvic inflammatory disease and endometritis in women.
