There is a foul-smelling white substance in the coronal sulcus

White substance with bad odor in the coronal sulcus will have many adverse effects on the patient's daily life. Usually, white substance with bad odor in the coronal sulcus is mostly caused by balanitis due to excessive foreskin. Patients with balanitis need to be diagnosed and treated in time to avoid transmitting the inflammation to their partners. It is recommended that other male friends should also take preventive measures in their daily lives to avoid such situations.

Because the foreskin is too long, the internal secretions cannot be cleared in time, allowing bacteria to grow and multiply here, which will cause an increase in the foreskin's internal secretions and smegma and odor. In severe cases, it will cause local inflammation, namely balanitis.

Patients with balanitis have abundant sebaceous glands in the foreskin, which can secrete a large amount of sebum. When the foreskin is too long, the secretions of the sebaceous glands in the foreskin cannot be discharged, and the sebum and the sediment in the urine synthesize into the cheese-like and smelly "smegma".

Smegma is suitable for bacterial growth, so it can cause inflammation of the glans penis and foreskin. Bacteria can also cause urinary tract infection through the urethra. Inflammation occurring at the urethral opening can cause the urethral opening to narrow after healing, resulting in difficulty in urination.

Candidal balanitis is more common in men with prepuce that is too long or phimosis. It is often transmitted from the spouse's candidal vaginitis, and can also be transmitted through sexual contact.

There is diffuse flushing of the inner foreskin and glans penis, and light red erosions and thin-walled pustules may be present on the glans penis and coronal sulcus, but Candida albicans is often not found, which may be caused by skin allergy to Candida albicans.

Prevention of candidal balanitis includes:

1. Be sure to complete the treatment according to the doctor's instructions;

2. Sexual partners receive examination and treatment at the same time;

3. Avoid sexual intercourse during treatment, and use condoms for recurrent patients;

4. Eliminate related predisposing factors, such as stopping the use of birth control pills, antibiotics, corticosteroids or immunosuppressants, controlling diabetes, not wearing synthetic or tight clothing, and circumcision for males with excessive foreskin;

5. Improve sanitary conditions, wash the vulva frequently, do not take a bath in a tub, change underwear frequently, and pay attention to the quality of sanitary napkins.
