What Condition Could Cause Small Red Dots on the Glans Penis without Pain or Itching?

Red dots on the glans penis are usually caused by conditions such as balanitis, pearly penile papules, and genital warts. Specific diagnosis requires detailed examination at a hospital.
1. Balanitis: Mainly caused by bacterial infection, it can lead to local itchiness, redness, and swelling. Due to inflammatory irritation, small red dots may appear locally. In the early stages, it does not cause pain or itchiness. Patients can take medications such as Levofloxacin Hydrochloride Tablets, Amoxicillin Capsules, and Metronidazole Tablets as prescribed by their doctors.
2. Pearly Penile Papules: Often caused by factors such as excessive foreskin or poor personal hygiene, it generally results in localized skin protrusions on the penis without causing pain or itchiness, leading to small red dots on the glans penis that are painless and non-itchy. Patients can undergo circumcision for treatment.
3. Genital Warts: Mainly due to poor sexual habits, genital warts usually grow on the glans penis. In mild cases and early stages, they do not cause pain or itchiness, resulting in small red dots on the glans penis that are painless and non-itchy. Patients can undergo laser surgery for treatment.
In addition to the above causes, other possibilities include repeated friction of the glans penis and allergies. Pay attention to self-care and maintain local cleanliness in the short term.
