Urethral Bumps: Are They STD or Just Sebaceous Cysts? - Internal Medicine

Urological issues


Hello doctor, I would like to ask you about a small, inconspicuous white bump near the urethral opening of the glans.
It is not easily observable, does not hurt, and there are no noticeable sensations.
Additionally, there seems to be an increase in the number of folds around the urethral opening, but there is no discomfort during urination and no issues with urinary flow.
I have not engaged in any sexual activity for the past year.
Could this be a sexually transmitted infection, or is it simply a sebaceous gland prominence? Also, does frequent masturbation have any impact on this condition?

Based on your description, it seems that it is not caused by a sexually transmitted infection or masturbation.
I recommend consulting a urologist for a proper diagnosis.
Please avoid self-medicating.
Thank you for your question.

More Info


When it comes to understanding urethral bumps, particularly those that appear near the glans or urethral opening, it is essential to differentiate between various potential causes. The presence of a small, white bump that is not painful and does not cause any discomfort during urination is often indicative of a benign condition rather than a sexually transmitted disease (STD).

One common explanation for such bumps is the presence of sebaceous cysts or sebaceous glands. These glands are responsible for producing sebum, an oily substance that helps lubricate the skin. Sometimes, these glands can become blocked, leading to the formation of small, painless bumps. These cysts are typically harmless and do not require treatment unless they become infected or bothersome.

Another possibility is the presence of pearly penile papules, which are small, dome-shaped bumps that can appear around the corona of the glans. They are a normal anatomical variation and are not associated with any disease or infection. Pearly penile papules are often mistaken for warts or other lesions but are completely benign.

Given that you have not engaged in any sexual activity for the past year, the likelihood of these bumps being related to an STD is significantly reduced. STDs typically present with additional symptoms such as pain, itching, unusual discharge, or sores. Since you mentioned that there is no discomfort, no changes in urination, and no other concerning symptoms, it is less likely that these bumps are indicative of an STD.

Regarding your question about masturbation, it generally does not have any adverse effects on the skin or the bumps you are describing. Masturbation is a normal sexual activity and, unless it causes irritation or injury, should not influence the presence of sebaceous cysts or other benign skin conditions.

However, if you notice any changes in the bumps, such as increased size, color changes, pain, or if you develop any new symptoms, it would be prudent to consult a healthcare professional for a thorough evaluation. A dermatologist or urologist can provide a more definitive diagnosis and reassurance.

In summary, based on your description, it seems likely that the bump you are observing is a benign sebaceous cyst or a normal anatomical variation rather than a sexually transmitted infection. Regular self-examinations and awareness of any changes in your body are good practices, and maintaining open communication with a healthcare provider can help address any concerns you may have in the future.
