What Causes Itching in the Scrotum Among Adolescents?

In general, itching of the scrotum in adolescents may be caused by inadequate hygiene, irritation and friction from clothing, scrotal eczema, scrotal dermatitis, or fungal infection. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under a doctor's guidance. The specific analysis is as follows:

1. Inadequate hygiene: Adolescents are physically active and prone to sweating. Sweat accumulation in the scrotal area can lead to bacterial growth and skin irritation, causing itching. Wash the scrotum and perineal area daily with warm water, gently pat dry with a clean towel afterward, and keep the area dry and fresh.

2. Clothing irritation and friction: Wearing tight synthetic underwear or pants made of coarse materials can continuously irritate and rub against the scrotum, leading to skin itching. Immediately switch to loose, breathable cotton underwear and choose loose-fitting pants to avoid compression and friction from tight clothing.

3. Scrotal eczema: Factors such as damp environments or mental stress may trigger scrotal eczema, characterized by redness, papules, and itching of the scrotal skin. Patients may use calamine lotion, desonide cream, or mometasone furoate cream as directed by a physician, and avoid scratching to prevent skin damage.

4. Scrotal dermatitis: Deficiency of vitamin B2 or bacterial infection may lead to scrotal dermatitis, presenting with erythema, scaling, and significant itching. Patients should take vitamin B2 tablets and apply mupirocin ointment or fusidic acid cream as prescribed, while increasing dietary intake of vitamin B2-rich foods such as eggs and spinach.

5. Fungal infection: Contact with contaminated clothing, towels, or other personal items may result in fungal infection of the scrotum, manifesting as ring-shaped red patches accompanied by itching. Patients may use terbinafine hydrochloride cream, bifonazole cream, or miconazole nitrate cream as directed by a doctor, and avoid sharing personal hygiene items with others.

In daily life, avoid washing the scrotal area with hot water or using harsh soaps and shower gels. Change underwear frequently, wash used underwear promptly, and sun-dry them for disinfection. Maintain regular sleep patterns, reduce consumption of spicy and irritating foods, and avoid worsening itching due to mental stress.
