A visit to the urologist turned into an eye-opening experience for a married man in Taiwan after doctors discovered a 30-year buildup of smegma—a natural but potentially harmful secretion—trapped beneath his foreskin. The man had sought medical help after experiencing sudden pain and noticing strange, yellowish flakes in the shower, fearing they might be kidney stones.
Dr. Chen Zhaoan, the urologist who examined him, was shocked to find a hardened, crust-like layer of smegma that had accumulated over decades. The patient, who had never been taught to clean beneath his foreskin, had no idea the buildup was even there. Medical staff carefully removed the deposits, which had become so solid they resembled scales, and preserved them for educational purposes.
The case, though rare, highlights a serious gap in basic hygiene education. Dr. Chen explained that while smegma is normal in small amounts, neglecting to clean it can lead to infections, unpleasant odors, and even long-term health risks. The patient’s lack of awareness was particularly surprising, as he had gone nearly 30 years without realizing the importance of proper cleaning.
Images of the extracted material later went viral, sparking discussions about male hygiene and the need for better health education. Dr. Chen reassured the public that doctors are there to help, not shame, and encouraged men to practice regular cleaning with water and mild soap.
The story serves as a wake-up call about the importance of personal hygiene—and how even the most basic habits can prevent shocking medical discoveries.
