What causes a white circle on the penis head?

Hello,

Welcome to icliniq.com

I read your query and understand your concern. I opened the file and saw white circles (attachment removed to protect the patient’s identity). They are not very clean, but as you stated without any problems or symptoms. In the first instance, I also thought about it as a fungal infection, as in females, white discharge, patches, or lines are also considered as fungal infection. So you are very lucky by applying fungal cream locally it starts healing. But if it is STD take a full course of treatment. One more thing is that it is a recurring disease. So if needed take again the course of treatment. Maintain hygiene of genital organs very carefully so chances of reoccurrence decrease. You have already gone for tests for major disease. Chlamydia and gonorrhea are very common STDs (sexually transmitted diseases). Laboratory tests also cover them usually. You treated yourself that way. I hope I have cleared all your doubts. Feel free to ask if you need further help.

Thank you.
