What is the condition when there is white substance and a smell of odor in the foreskin?

Patient's question:

After retracting the foreskin, I noticed white substance inside and a bad odor. I've been quite careful with hygiene, but suddenly discovered this two weeks ago. What could this be? Should I take some medication or something?

Doctor's answer:

Hello! Based on your description, it can be determined that it is smegma, which is a condition that occurs in individuals with excessive foreskin. During urination, the foreskin remains covering the glans, and a small amount of urine remains trapped between the foreskin and the glans. The water in the urine evaporates under the influence of body temperature, while the remaining residues form smegma between the foreskin and the glans. Smegma is white and has a foul odor.
Having smegma is not a major issue. It can be managed with regular cleaning. When cleaning, make sure to fully retract the foreskin and rinse it with clean water. It is best to wash it once before bed every day. Additionally, pay close attention to hygiene in your daily life.
