What causes scrotal itching and how is it treated?

Generally, scrotal itching is caused by friction, sweat irritation, allergies, scrotal eczema, or scrotal dermatitis. If abnormal symptoms occur, it is recommended to seek timely medical evaluation to determine the underlying cause and receive appropriate treatment. Specific causes are analyzed as follows:

1. Friction

Friction between clothing and skin can cause minor skin damage, making the skin more susceptible to irritation and infection, leading to itching. This may be accompanied by redness, pain, or slight abrasions. It is recommended to wear loose, breathable cotton underwear to reduce friction. Using moisturizing skincare products can help repair damaged skin.

2. Sweat Irritation

In hot weather or after intense physical activity, sweating in the scrotal area is common. The salt and bacteria in sweat may irritate the skin and cause itching. Wearing breathable cotton underwear and avoiding tight-fitting clothes is advised. Applying baby powder or specialized anti-itch powders containing zinc oxide can help absorb moisture and reduce friction.

3. Allergy

Certain skincare products, detergents, or other substances may trigger allergic reactions in sensitive individuals upon skin contact, resulting in redness, papules, severe scrotal itching, and dry skin. Recommended treatments include avoiding known allergens or irritants and using medications such as hydrocortisone cream, triamcinolone acetonide cream, or fexofenadine tablets to reduce inflammation and relieve itching.

4. Scrotal Eczema

Scrotal eczema may result from impaired skin barrier function and abnormal immune responses. It primarily manifests as redness, swelling, oozing, and itching of the scrotal skin. Symptoms can be managed under medical guidance with topical treatments such as fluocinonide acetate ointment, calamine lotion, or zinc oxide ointment.

5. Scrotal Dermatitis (Inflammation)

Scrotal dermatitis is usually caused by bacterial or fungal infections. These pathogens irritate the scrotal skin, triggering an inflammatory response that leads to itching and pain. Symptoms may include redness, erosion, and exudation of the scrotal skin. Doctors typically prescribe antimicrobial agents based on the causative pathogen, such as levofloxacin tablets, metronidazole tablets, or clotrimazole cream, along with maintaining a dry and well-ventilated scrotal area.

It is recommended to maintain daily cleanliness and dryness of the scrotal area, follow a healthy lifestyle with sufficient sleep, improve dietary habits, regulate overall physical condition, and promote general health.
