What causes men's scrotum to itch?

For a man, the health of the testicles is probably the most important thing that cannot be ignored, because the testicles are a very important reproductive organ. If there is a problem with the testicles, it will affect fertility. For example, some men may find that the testicles are itchy. Since itching is not a very serious problem, many men will ignore it directly. This is not correct. People need to understand why men have itchy testicles.

Scrotal itching

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 large 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 tension and 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.

Differential diagnosis

1. Scrotal swelling

It refers to the lesions of the scrotal skin and its contents (the tunica testis, epididymis and spermatic cord), or the descent of abdominal contents (ascites and viscera) into the scrotum, causing the scrotal volume to increase.

2. Scrotal eczema

Small white bumps on the scrotum may be an important symptom of scrotal eczema, the most common type of eczema, which is limited to the scrotal skin, sometimes extending to the anus, and rarely to the penis. This disease is severely itchy, the rash is polymorphic, and it is easy to relapse. It can be treated. To achieve the goal of radical cure, personal hygiene needs to be paid attention to, medication is taken regularly, and family members should be avoided from being infected.

3. Scrotal prolapse

Orchitis and epididymitis are common causes of scrotal prolapse. There is usually an acute attack of fever, acute swelling of the epididymis and testicles, and pain, which then turns into a chronic condition, followed by prolapse pain, which is sometimes mild and sometimes severe. Sometimes the patient can feel a small painful nodule in the scrotum.
