Introduction
Internal factors: These include individuals with certain allergic constitutions, those experiencing significant emotional fluctuations or prolonged psychological stress, as well as those with endocrine disorders, chronic gastrointestinal diseases, or immune system abnormalities—such individuals are more prone to developing scrotal pruritus.
External factors: Scrotal pruritus may be triggered by irritation resulting from sweat accumulation on the scrotal skin or friction from undergarments.
Itching of the scrotum is commonly associated with conditions such as scrotal eczema, allergic dermatitis, and scabies. It is a very common symptom, particularly prevalent among young men.
① Internal factors
These include individuals with allergic constitutions, those experiencing significant emotional fluctuations or prolonged psychological stress, as well as patients with endocrine disorders, chronic gastrointestinal diseases, or immune system abnormalities—all of whom are more prone to developing scrotal itching.
② External factors
Wearing overly tight, poorly ventilated, or non-absorbent undergarments may irritate the scrotal skin due to prolonged exposure to sweat and friction from underwear—potentially triggering this condition, especially during summer when elevated temperature and humidity in the genital area create a favorable environment for irritation. Additionally, individuals with skin allergies who come into contact with parasitic mites (e.g., Sarcoptes scabiei) may develop intense pruritus, as these mites burrow into the epidermis.
Therefore, patients experiencing scrotal itching should maintain a varied and nutritious diet, emphasizing fresh vegetables and fruits—rich sources of vitamins B and C—which may help prevent and alleviate scrotal eczema. At the same time, they should avoid spicy and irritating foods, such as scallions, ginger, garlic, and chili peppers, as well as stimulating beverages including strong tea, coffee, and alcoholic drinks, to prevent exacerbation of symptoms.
