Mycoplasma genitalium is now recognised as a significant STI. Standard antibiotics often fail. Get tested with resistance profiling.
Mycoplasma genitalium (Mgen) is an emerging sexually transmitted bacterium that causes urethritis in men and cervicitis/PID in women. It's particularly concerning because of high rates of antibiotic resistance - standard azithromycin often fails in up to 50% of cases. Our testing includes resistance marker detection to help guide appropriate management.

Mgen has developed high resistance to azithromycin, the antibiotic traditionally used for STIs. Up to 50% of UK strains are resistant. Resistance marker testing helps guide appropriate treatment.
Untreated Mgen can cause persistent urethritis in men and PID in women, potentially affecting fertility. It also increases HIV transmission risk. With correct treatment guided by resistance testing, it's curable.
Mgen is sexually transmitted through genital contact. It can be passed through vaginal, anal, and possibly oral sex. Using condoms significantly reduces transmission risk.
Syphilis blood tests at the 6-week mark typically provide highly reliable results, with accuracy rates exceeding 95% for detecting infection. Understanding test accuracy can help reduce anxiety whilst ensuring appropriate screening decisions.
Experiencing non-consensual condom removal during sexual activity can understandably cause significant concern about potential STI exposure. Understanding your options and the testing process can help provide clarity during what may be a distressing time.
Mycoplasma genitalium (Mgen) has emerged as one of the most concerning sexually transmitted infections in recent years, yet many people remain unaware of its existence. Testing for this increasingly common STI has become critical due to rising infection rates and [growing antibiotic resistance](/blog/mgen-mycoplasma-genitalium-harder-to-treat).
