Glansitis using laser treatment is ineffective, the relevant pathogenic bacterial infection needs to be clarified and the relevant drugs targeted for treatment. First, it is necessary to clarify whether the patient has diabetes or whether there is a condition where the immunity is reduced and the normal flora of the organism is suppressed due to long-term use of antimicrobials. Second, to further analyze the cause of glansitis, if there has been unclean sexual contact, there may be gonococcus, mycoplasma, chlamydia and other infections caused. If there is more dirt for a long time and you don’t pay attention to personal cleaning, you may have glansitis due to non-infectious factors caused by foreskin scale. It can also be caused by common bacterial infections or the presence of infections such as fungi and trichomonas. Different infections need to be treated with different medications, such as bacterial infections can be treated with antibiotic ointment for external application.

For combined trichomonas infections, the use of metronidazole has a specific therapeutic effect, while other drugs are not ideal for treatment.
