The main way to check for mycoplasma in men is by taking urethral secretions for culture. A small amount of secretion is taken inside and around the urethra using a relatively fine cotton swab, placed in a dry test tube and then promptly sent to a laboratory for culture, where a drug sensitivity test can be done and a sensitive antibiotic can be selected for treatment once the infection is confirmed. The UTI caused by mycoplasma infection is called non-gonococcal urethritis, which is also a more common type of urethritis in men, and the more sensitive antibiotics for treatment are macrolide antibiotics, such as erythromycin, roxithromycin, azithromycin, clarithromycin. Some men with mycoplasma infection can affect semen, leading to sperm deformities and decreased vitality. Mycoplasma infection has an impact on male fertility, which is promptly confirmed by relevant tests and then promptly treated.
