Patient's question:

Patient Gender: Male
Detailed Condition and Purpose of Consultation: There is discharge from the urethra in the morning.

Doctor's answer:

Hello, there is a lot of discharge from the urethral meatus (purulent discharge or dripping white): Urethral discharge is mainly seen in sexually transmitted diseases, such as white substances leaking out or some viscous liquid sticking around the urethral meatus. It is mainly seen in gonorrhea, urethritis, balanitis, etc. This condition generally indicates an infectious or obvious inflammatory stage, which is a critical moment for treatment.
