There are white flakes on the glans?


Hello doctor, in the past few days, I have noticed small white flakes on the glans, and there is also some dirty residue rubbing against the inner side of the foreskin.
Could you please help me with this? Thank you.

It might not be cleaned properly.
Essentially, there are sebaceous secretions around the glans and foreskin, which can lead to the issues you've noticed to some extent.
If there is no pain or itching and it is cleaned well, then there is no cause for concern!

More Info


The presence of white flakes on the glans (the head of the penis) can be concerning and may indicate several potential conditions. The most common causes of this symptom include smegma accumulation, fungal infections, or skin conditions such as psoriasis or lichen sclerosus. Understanding these causes can help in determining the appropriate treatment and management strategies.

1. Smegma Accumulation: Smegma is a natural substance made up of dead skin cells, oils, and moisture that can accumulate under the foreskin in uncircumcised males. It can appear as white flakes or a cheesy substance. Regular hygiene practices, including gentle cleaning of the area with warm water, can help prevent smegma buildup. If you are uncircumcised, it is essential to retract the foreskin during cleaning to ensure that smegma does not accumulate.

2. Fungal Infections: Conditions such as candidiasis (a yeast infection) can lead to white patches or flakes on the glans. This is often accompanied by itching, irritation, or a burning sensation. Fungal infections can occur due to various factors, including a warm, moist environment, poor hygiene, or antibiotic use that disrupts normal flora. Antifungal creams or medications prescribed by a healthcare provider can effectively treat these infections.

3. Skin Conditions: Certain dermatological conditions can also cause white flakes on the glans. For instance, psoriasis can lead to scaly patches, while lichen sclerosus may cause white, shiny patches and can be associated with itching and discomfort. These conditions often require a dermatologist's evaluation and may be treated with topical steroids or other medications.

4. Sexually Transmitted Infections (STIs): Although less common, some STIs can present with similar symptoms. If there is any suspicion of an STI, it is crucial to seek medical attention for appropriate testing and treatment.

5. Hygiene Practices: Regardless of the underlying cause, maintaining good hygiene is essential. This includes washing the genital area daily with mild soap and water, ensuring the area is dry afterward, and avoiding irritants such as harsh soaps or lotions.

If you are experiencing persistent symptoms, discomfort, or if the condition worsens, it is advisable to consult a healthcare professional. They can perform a physical examination, take a detailed history, and possibly conduct tests to determine the exact cause of the white flakes. Based on the diagnosis, they can recommend appropriate treatments, which may include topical medications, lifestyle changes, or further investigations if necessary.

In summary, while white flakes on the glans can be benign and related to hygiene, they can also indicate underlying conditions that may require medical attention. Regular cleaning, awareness of any accompanying symptoms, and seeking professional advice when needed are key steps in managing this issue effectively.
