Share to:

Hello, how can I assist you?


Hello doctor: I would like to ask about a condition where the frenulum of the foreskin extends downward and appears as a narrow red line that is slightly swollen, with one or two small bumps on top.
It is not itchy or painful.
What could this be? Thank you, doctor.

Lee: Hello, I also cannot determine the best course of action, so it is advisable to seek medical attention as soon as possible.
It could be a tumor, warts, infection, inflammation, etc.
If there are any unclear aspects, feel free to ask again, and we can discuss and research further.
Online responses can only serve as a reference; if necessary, it is still important to visit a healthcare facility.

More Info


The symptoms you are describing regarding the redness and swelling in the frenulum, along with the presence of small bumps, can be indicative of several conditions, but it is essential to approach this with a thorough understanding of urological health.

Firstly, the frenulum is a band of tissue that connects the foreskin to the glans of the penis. Any changes in this area, such as redness, swelling, or the appearance of bumps, can be concerning and warrant further investigation. Here are some potential causes for your symptoms:
1. Frenulum Breve: This condition occurs when the frenulum is shorter than normal, which can lead to tension and irritation. While it may not always cause pain or discomfort, it can lead to inflammation and redness.

2. Infection: A localized infection, such as a yeast infection or bacterial infection, can cause redness and swelling. Even if there is no pain or itching, an infection can still be present and may require treatment.

3. Irritation or Allergic Reaction: Sometimes, irritation from soaps, lotions, or other products can lead to inflammation in the area. An allergic reaction to a product can also manifest as redness and swelling.

4. Pearly Penile Papules: These are small, harmless bumps that can appear on the frenulum or around the glans. They are a normal anatomical variant and do not require treatment unless they cause concern.

5. Fordyce Spots: These are small, painless, pale bumps that can appear on the penis and are caused by enlarged sebaceous glands. They are benign and do not require treatment.

6. Sexually Transmitted Infections (STIs): Some STIs can present with symptoms such as redness and swelling. It is crucial to consider this possibility, especially if there has been any change in sexual partners or practices.

Given that your symptoms are not accompanied by pain or itching, it may suggest a less severe condition, but it is still important to seek medical advice. A healthcare professional, particularly a urologist, can perform a physical examination and may recommend further tests, such as a swab or urine test, to rule out infections or other underlying conditions.

In terms of management, if the condition is due to irritation or an allergic reaction, avoiding the offending products may help. If an infection is diagnosed, appropriate antifungal or antibiotic treatment may be necessary. For anatomical variations like frenulum breve or pearly penile papules, reassurance and education about the condition are often sufficient.

In conclusion, while your symptoms may not seem severe, it is always best to consult with a healthcare provider to ensure proper diagnosis and treatment. Early intervention can prevent potential complications and provide peace of mind. If you have any concerns about sexually transmitted infections or other urological issues, do not hesitate to bring these up during your consultation.
