What causes swelling of the glans penis?

Swelling of the glans penis typically refers to the swelling of the penile skin or foreskin, which may be caused by various factors. 1. Sexual stimulation: During sexual arousal, penile vasodilation may lead to skin swelling, which usually subsides naturally after sexual activity. 2. Local trauma: Trauma to the penis, such as friction during sexual intercourse, may cause localized edema, which can be relieved with cold compresses. 3. Inflammation: Conditions such as balanitis or posthitis may occur due to bacterial proliferation, causing inflammation and subsequent swelling; medication may be required for treatment. 4. Disease-related factors: Urethritis, cavernitis, or other conditions may also result in penile skin swelling; treatment should be based on the underlying cause. If glans penis swelling occurs, prompt medical consultation is recommended to identify the cause and follow medical advice for treatment. Additionally, maintaining good personal hygiene and healthy lifestyle habits can help prevent such issues.
