White Bumps Behind the Glans: A Guide for Teens - Urology

Share to:

There are white granular substances located at the back between the glans and the foreskin?


Hello Doctor: I have three hard white bumps located behind the glans.
They are not painful to the touch and cannot be felt when not erect, but can be faintly felt when semi-erect (they can be felt when the foreskin is retracted).
When fully erect, they can be clearly felt without retracting the foreskin.
I am just an ordinary high school student and have not engaged in sexual intercourse yet.

This is a rough diagram of what it looks like when the foreskin is retracted.
My white bumps are located "here" in the diagram.
I am worried that I might have some unusual condition, and I feel too shy to visit a clinic, so I am asking here.
I hope the doctor can explain what is happening with my little buddy...

Classmate: Hello, I can only say that it's hard to determine.
It could be a sebaceous gland issue or other conditions like acne or folliculitis.
I still recommend seeking medical attention.
If there are any unclear points, feel free to ask again, and we can discuss and research further.

More Info


It's understandable to feel concerned about any changes in your body, especially during your teenage years when many changes are occurring. The white bumps you are describing behind the glans (the head of the penis) could be a common condition known as pearly penile papules. These are small, harmless bumps that typically appear in rows around the corona (the ridge of the glans). They are completely normal and are not a sign of any disease or infection.

Pearly penile papules are often mistaken for other conditions, such as genital warts or other sexually transmitted infections (STIs), but they are not contagious and do not require treatment. They are a natural anatomical variation and are more common in uncircumcised males. The fact that they are hard, non-painful, and only noticeable during an erection further supports the likelihood that they are pearly penile papules.

It's important to note that many young men experience anxiety about their genital health, especially when they notice something unusual. However, if you are experiencing any pain, discomfort, or changes in color, or if the bumps change in appearance, it would be wise to consult a healthcare professional for a proper evaluation. They can provide reassurance and rule out any other potential issues.

In addition to pearly penile papules, other benign conditions can cause white bumps in the genital area, such as sebaceous cysts or Fordyce spots, which are small, painless, pale bumps that can appear on the shaft of the penis or the scrotum. These are also normal and do not require treatment unless they become bothersome.

If you are feeling anxious about your genital health, here are a few tips to help you manage your concerns:
1. Educate Yourself: Understanding what is normal and what is not can help alleviate anxiety. Resources such as reputable medical websites or books can provide valuable information.

2. Talk to Someone: If you feel comfortable, discussing your concerns with a trusted adult, such as a parent or guardian, can provide support and guidance.

3. Consult a Healthcare Professional: If you are still worried, consider visiting a healthcare provider. They can offer a professional opinion and help you feel more at ease.

4. Practice Good Hygiene: Keeping the genital area clean and dry can help prevent irritation and infections. Regular washing with mild soap and water is usually sufficient.

5. Avoid Self-Diagnosis: It can be tempting to search online for answers, but this can often lead to unnecessary worry. A healthcare professional can provide accurate information tailored to your situation.

In conclusion, the white bumps you are experiencing are likely normal anatomical features, but if you have any doubts or if your symptoms change, seeking medical advice is always a good idea. Remember, taking care of your health is important, and being proactive about your concerns is a positive step.
