Vulva itching and redness can make people feel very uncomfortable. At this time, you should go to the hospital for examination and treatment in time, because many times, the cause of this symptom is disease. Today, the editor will introduce to you in detail the causes of vulva itching and redness, hoping to be helpful to you.

Disease 1: Scrotal itching

Cause: Local dampness is a major cause of scrotal itching. The scrotum itself has glandular secretions, and sweating is frequent. If you often wear tight, synthetic underwear that is not good at absorbing sweat and is not ventilated, it is easy to cause scrotal itching. Having sex with a woman with candidal vaginitis can also cause scrotal itching due to the irritation of the male genitals by the inflammatory secretions. In addition, mental tension, the stimulation of spicy food, friction, static electricity, and the irritation of the vulva skin by detergent residue on the underwear can also induce scrotal itching.

Disease 2: Scrotal eczema

Cause: It is related to the individual's eczema predisposition, so allergy is an important inducement, including underwear materials, dyes, shrimp, crab, beef, peanuts, alcohol, etc. in diet, which can induce scrotal eczema. In addition, humidity, friction, mental and nervous factors and seasonal climate can induce or aggravate the disease.

Disease 3: Candida infection

Cause: Candida infection is a fungal infection. Diabetic patients have high sugar content in their bodies, poor resistance, and fungi are easy to grow; chronic disease patients who often use immunosuppressants, anti-tumor drugs, and hormones have poor body resistance and are also difficult to resist fungal invasion; long-term use of antibiotics will cause flora imbalance, which is conducive to fungal reproduction; having sex with women with the disease may also cause infection.

Disease 4: Tinea cruris

Cause: Fungal infection. It often occurs in summer, and young men who love sports and sweat a lot are susceptible.
