What causes scrotal itching?

Scrotal itching seems to be one of the problems encountered by many men. If you do not pay attention to hygiene, the urinary and other reproductive systems are prone to breeding bacteria, causing inflammation and thus illness. There are many reasons for scrotal itching, which may be due to scrotitis or eczema. If the itching symptoms are not relieved, it is best to go to the hospital for a check-up to determine the specific type of disease.

Scrotal itching (pruritus scroti) is a very common symptom, especially in young men. The causes of scrotal itching are relatively complex, with both internal and external factors. Scrotal itching is generally caused by scrotal eczema, allergic dermatitis, scabies, etc. People with allergic constitutions, long-term mental tension, and emotional fluctuations are prone to this disease.

Causes and common diseases

1. Gentle and humid vagina

It is more common in physical laborers, especially in summer, when the genitals are hot, sweaty, humid, and poorly ventilated. The scrotal skin is stained by sweat and rubbed by underwear, causing itching. Wearing tight jeans or non-absorbent, non-breathable nylon underwear can also cause itching.

2. Riboflavin (vitamin B2) deficiency

It can lead to scrotitis. The scrotum will show changes such as erythema, dryness, scaling, papules and crusts, accompanied by itching. At the same time, angular cheilitis, glossitis and oral ulcers may also occur.

3. Inflammation

Scrotitis caused by fungi, such as candidal scrotitis and tinea cruris involving the scrotum, can cause scrotal itching.

4. Other diseases

Neurodermatitis, allergic dermatitis, scabies, eczema, etc. in the scrotal area can all cause itching.

5. Internal and external factors

People with allergic constitutions, those who are under long-term mental stress, and those who have large mood swings are prone to this disease. In addition, people with certain diseases, such as chronic digestive system diseases, gastrointestinal dysfunction, endocrine disorders, and metabolic disorders, are also prone to this disease under the influence of external factors.
