White Spots on the Glans: Causes and Concerns - Urology

Understanding white spots on the glans (the head of the penis) can be a source of concern for many individuals. These spots can arise from various causes, and their persistence or disappearance during an erection can depend on the underlying condition.

Firstly, it’s important to recognize that white spots on the glans can be caused by several factors, including:
1. Pearly Penile Papules: These are small, benign, white or skin-colored bumps that typically appear around the corona of the glans. They are a normal anatomical variant and are not associated with any disease. They do not change with erection and remain present regardless of blood flow.

2. Fordyce Spots: These are small, painless, pale bumps that are sebaceous glands without hair follicles. They are common and harmless, and like pearly penile papules, they do not disappear during an erection.

3. Lichen Sclerosus: This is a chronic inflammatory skin condition that can cause white patches on the glans. The spots may remain visible regardless of whether the penis is erect or flaccid. This condition may require medical evaluation and treatment.

4. Vitiligo: This is a skin condition characterized by the loss of pigment, leading to white patches. Vitiligo can affect any part of the body, including the genital area, and the spots will not disappear with an erection.

5. Infections: Certain sexually transmitted infections (STIs) or fungal infections can cause white spots or lesions on the glans. These may change in appearance with blood flow or inflammation but typically require medical evaluation for diagnosis and treatment.

6. Other Dermatological Conditions: Conditions such as psoriasis or eczema can also lead to white patches or spots on the glans. These conditions may have varying presentations and could change with the state of the tissue.

Regarding your specific question about whether the white spots would disappear or persist during an erection, it largely depends on the cause. For benign conditions like pearly penile papules or Fordyce spots, the spots will remain visible regardless of the state of erection. In contrast, if the white spots are due to an inflammatory or infectious process, they may appear more pronounced during an erection due to increased blood flow and tissue engorgement, but they will not disappear.

If you notice new white spots, changes in existing spots, or if they are accompanied by other symptoms such as pain, itching, or discharge, it is advisable to consult a healthcare professional for a thorough examination. A urologist or dermatologist can provide a proper diagnosis and recommend appropriate treatment if necessary.

In summary, while many white spots on the glans are benign and will not change with an erection, some conditions may require medical attention. Understanding the nature of these spots is crucial for addressing any concerns and ensuring proper care.
