Can povidone-iodine be applied to the glans penis?

Povidone-iodine is a commonly used disinfectant, primarily composed of iodine and polyvinylpyrrolidone. It is often used for cleaning and disinfecting the skin. In certain situations, such as balanitis caused by phimosis or post-operative cleaning, appropriate use of povidone-iodine to clean the glans is acceptable. However, the following points should be noted: 1. Sensitivity test: Before use, perform an allergy test on a small area of skin first, as some individuals may be allergic to iodine or its components. 2. Gentle application: Avoid excessive rubbing to prevent irritation to the delicate skin. 3. Appropriate concentration: Ensure the concentration of povidone-iodine is suitable for topical application. Usually, a low concentration (1% or lower) is safer. 4. Avoid prolonged contact: Povidone-iodine should not be left on the skin for extended periods. It should be rinsed off promptly after cleaning to minimize skin irritation. If you are unsure whether it is appropriate to use or if symptoms are severe, please consult a doctor for advice.
