Itchy glans with white discharge should be considered first for the presence of infectious factors and then for other non-infectious factors. Infectious factors are the most common cause, most likely due to infectious factors, such as Escherichia coli, Mycoplasma or Chlamydia, gonococcus, enterococcus, candida, etc. For glansitis caused by infectious factors, you should first take appropriate treatment measures for the causative pathogenic microorganisms, such as enterococci or E. coli, you can apply some antibiotic ointment, if it is caused by streptococci, you can apply antifungal ointment, if it is caused by trichomonas, you can use metronidazole-type drugs to treat. It can also be caused by other non-infectious factors, such as the use of external cleansers or allergies to condoms or substances inside condoms, etc., resulting in more glans irritation and discharge. Of course, there is also the possibility that the foreskin is too long combined with the lack of attention to personal hygiene resulting in too much dirt stored between the foreskin and the glans, stimulating the glans to itch. The first thing you should do is to take care of your personal hygiene, wash your glans and change your underwear regularly, and your underwear should be loose and breathable to help improve and recover from the condition. For long foreskin, circumcision can be done. For the condition of itchy glans and white discharge, you should go to the hospital in time to do a checkup to clarify the cause and then do targeted treatment.
