    Mgen Partner Treatment: Do Partners Need Testing?

    Mgen Reinfection: Why It Comes Back & How to Prevent

    Mgen reinfection happens when you get re-exposed to Mycoplasma genitalium after a cure — usually through an untreated partner who passes it back — rather than the original infection never clearing. Tr

    Mgen Symptoms in Women: Discharge, Bleeding & Pain

    Mycoplasma genitalium often causes no symptoms in women, but when it does, the most common signs are cervicitis-related: unusual vaginal discharge, bleeding between periods or after sex, pain during i

    Mgen Test of Cure: Timing & Why It's Needed

    A Mycoplasma genitalium (Mgen) test of cure is a repeat NAAT done 3-4 weeks after you finish treatment to confirm the bacterium is gone. It matters because macrolide resistance now causes the standard

    Mgen in the Throat: Oral Infection Risk & Testing

    There's no good evidence that Mycoplasma genitalium (Mgen) reliably infects or causes disease in the throat. This bug is a urogenital pathogen — it's established in the urethra and cervix, but pharyng

    Mgen vs Chlamydia: Symptoms, Testing & Treatment

    How Mycoplasma Genitalium Spreads (and Oral Risk)

    Mycoplasma genitalium spreads almost entirely through sexual contact — vaginal and anal sex that brings genital mucous membranes and fluids together. It's a true STI, not something you catch from toil

    Mgen Testing: NAAT, Resistance Assay & When to Test

    Mgen testing uses an FDA-cleared NAAT (nucleic acid amplification test) on a urine sample or a swab to detect Mycoplasma genitalium 's genetic material. Because macrolide resistance is now common, cur

    Is Mycoplasma Genitalium Curable? Treatment & Resistance

    Mycoplasma genitalium is usually curable, but the word comes with a condition: cure now depends on matching the antibiotic to the strain. Because more than half of strains in many areas resist the old
