What should men do if their penis itches?

If a man finds that his penis is itchy, he should pay attention to it, because if there is balanitis or some early symptoms of sexually transmitted diseases, it may cause this itching symptom, so he must pay attention to treating the symptoms.

1. Contact dermatitis: A small number of men with allergic constitutions may develop dermatitis reactions such as erythema and papules on the skin in contact with the underwear, causing itching, because the clothes are close to the perineal skin and the area is easily soaked by sweat.

2. Balanitis: Men with excessive foreskin or phimosis usually suffer from chronic inflammatory reactions due to the accumulation of smegma in the coronal sulcus of the foreskin. They are also prone to condyloma acuminatum and often experience local itching.

3. Pubic lice: Pubic lice have special hook-shaped claws that grab the skin in the pubic area and the sweat hair around the anus. Their bites and the stimulation of their saliva toxins can cause local skin itching, folliculitis, and eczema-like changes.

4. Tinea cruris and tinea glutealis: Men with obese and sweaty physiques are prone to fungal growth and reproduction due to their sweaty and moist vulva, which can lead to tinea cruris and tinea glutealis. The symptoms are ring-shaped red papules at the base of the thigh or buttocks, which often cause scaling and itching.

5. Caused by non-infectious factors, including local trauma, friction, contraceptives, soaps and detergents, etc., the local area may show edema, erythema, erosion, exudation and even bleeding. If secondary bacterial infection occurs, it may cause suppuration and form an ulcer surface.

6. People with allergies, chronic mental tension, and mood swings are also prone to penile itching.

7. People with chronic digestive diseases, gastrointestinal disorders, endocrine disorders, and metabolic disorders are also prone to penile itching due to external factors.
