What causes yellow stains on male underwear?

Yellow stains on male underwear can be caused by various factors, including:

1. Sweat: Sweat, especially if it is allowed to dry on the fabric, can leave yellow stains due to the salts and oils present in sweat.
2. Urine: Accidental dribbling of urine or inadequate cleaning after urination can result in yellow stains on underwear.
3. Body oils and secretions: Body oils, skin cells, and other secretions can accumulate on the fabric and lead to yellow discoloration.
4. Hygiene: Poor hygiene practices, such as not washing underwear regularly or using harsh detergents, can contribute to the development of stains.
5. Medical conditions: Certain medical conditions, such as fungal infections or excessive sweating (hyperhidrosis), can also cause yellow stains on underwear.

To prevent and remove yellow stains, it is recommended to:

• Wash underwear regularly with a gentle detergent.
• Avoid using bleach, as it can react with sweat or urine and worsen the stains.
• Ensure thorough cleaning after urination.
• Consider seeking medical advice if the stains persist or are accompanied by other symptoms.
