Red spots on the glans of the penis that fluctuate in severity?


Hello doctor, I have a question.
Sometimes I notice red spots on my glans and coronal sulcus, but they come and go.
They are more noticeable when I am erect.
I have visited the doctor three times, and each time the physician found nothing abnormal.
However, during self-examination, I sometimes see red spots in the same area, and sometimes I do not.
Is this normal? Thank you, doctor.

When it comes to occasional red dots on the glans (the head of the penis) and the coronal sulcus (the groove where the glans meets the shaft), it’s understandable to feel concerned, especially if you notice changes in their appearance. Based on your description, it seems that you have already consulted with a physician multiple times, and they have not found any abnormalities. This is a positive sign, but let’s delve deeper into what these red dots could signify and when you should consider seeking further medical advice.

Firstly, it’s important to recognize that the skin on the glans and surrounding areas can be sensitive and may react to various stimuli. The occasional appearance of red dots can be attributed to several benign causes, including:
1. Irritation or Friction: Activities such as sexual intercourse, masturbation, or even vigorous cleaning can lead to temporary irritation. This irritation can manifest as redness or small red spots, particularly during or after an erection when blood flow increases to the area.

2. Allergic Reactions: Sometimes, products such as soaps, lotions, or even condoms can cause allergic reactions that result in localized redness or spots. If you’ve recently changed any personal care products, consider reverting to your previous ones to see if there’s an improvement.

3. Pearly Penile Papules: These are small, harmless bumps that can appear around the corona of the glans. They are a normal anatomical variation and are not a cause for concern.

4. Folliculitis: This is an inflammation of the hair follicles, which can occur in the genital area. It can present as small red bumps and is usually self-limiting.

5. Infections: While your doctors have ruled out any significant issues, it’s worth noting that certain infections (like sexually transmitted infections) can cause changes in the appearance of the skin. If you experience additional symptoms such as pain, discharge, or persistent redness, it would be prudent to seek further evaluation.

Given that you have had thorough examinations and your doctors have not found any concerning issues, it is likely that what you are experiencing is benign. However, it’s essential to monitor the situation. Here are some guidelines on when to seek further medical attention:
- Persistent Symptoms: If the red dots do not resolve or if they become more frequent or widespread, it’s advisable to consult a healthcare professional again.

- Accompanying Symptoms: If you notice any additional symptoms such as pain, itching, swelling, or discharge, these could indicate an underlying issue that requires further investigation.

- Changes in Appearance: If the red dots change in color, size, or shape, or if new symptoms develop, it’s important to have these evaluated.

- Mental Health Impact: If the appearance of these red dots is causing you significant anxiety or distress, discussing your concerns with a healthcare provider can help alleviate your worries, even if the physical examination does not reveal any issues.

In conclusion, occasional red dots on the glans that come and go, especially when evaluated by a physician without any findings of concern, are often benign. However, staying vigilant and aware of any changes or accompanying symptoms is crucial. If in doubt, don’t hesitate to reach out to a healthcare professional for peace of mind. Your health and comfort are paramount, and it’s always better to err on the side of caution when it comes to changes in your body.
