Red Dots on the Glans: What Could They Indicate? - Urology

There are small red spots on the glans?


Hello, doctor.
I am a senior in high school.
Last night, while using the restroom, I suddenly noticed about 10 small red spots on the surface of my glans (approximately the size of a 0.5 mm pen dot on paper).
They are not painful or itchy, and they are flat, meaning they do not feel raised when touched.
What could this symptom be? I am a bit worried it might be a sexually transmitted infection, as I have engaged in sexual activity with someone.

Hello, it could be a sexually transmitted infection or a common skin condition.
Since you have ten red spots and are concerned, I recommend that you visit a urology clinic for an examination.

The appearance of red dots on the glans (the head of the penis) can be concerning, especially for someone who is sexually active. However, it's important to understand that not all red spots or dots are indicative of a sexually transmitted infection (STI) or any serious medical condition.
Based on your description, the red dots are small, flat, and not associated with pain or itching. This presentation could suggest several benign conditions. Here are a few possibilities:
1. Pearly Penile Papules: These are small, harmless bumps that can appear around the glans and are often mistaken for warts or other lesions. They are a normal anatomical variant and are not associated with any disease or infection.

2. Folliculitis: This is an inflammation of the hair follicles, which can occur anywhere on the body, including the genital area. It can present as small red bumps and is usually not painful unless there is an infection.

3. Allergic Reaction or Irritation: Sometimes, irritation from soaps, lotions, or even friction from clothing can lead to localized redness or bumps. If you've recently changed any products or had increased friction, this could be a cause.

4. Infection: While less likely given the absence of pain or itching, certain infections can present with red spots. For example, a mild yeast infection or a bacterial infection could cause such symptoms. However, these typically come with other signs such as discharge, itching, or discomfort.

5. Sexually Transmitted Infections (STIs): Certain STIs can present with red spots or lesions. For example, herpes can cause small red bumps that may eventually blister, and syphilis can cause sores. However, these usually come with additional symptoms.

Given your concern about STIs, it is advisable to consult a healthcare professional for an accurate diagnosis. They may perform a physical examination and, if necessary, conduct tests to rule out any infections.
In the meantime, here are some general recommendations:
- Avoid Irritation: Keep the area clean and dry. Avoid using harsh soaps or lotions that may irritate the skin.

- Monitor Symptoms: Keep an eye on the red dots. If they change in appearance, become painful, or if you develop other symptoms (such as discharge, fever, or swelling), seek medical attention promptly.

- Practice Safe Sex: If you are sexually active, using condoms can help reduce the risk of STIs.

In conclusion, while the presence of red dots on the glans can be alarming, many potential causes are benign. However, due to your sexual history and the nature of the symptoms, it is essential to seek medical advice to ensure proper evaluation and peace of mind.
