What can cause a red foreskin?

A red foreskin can be caused by several factors. Some of the most common causes include:

1. Inflammation: Inflammation of the foreskin, known as balanitis, can cause redness, swelling, and pain. This can be caused by various factors, including infections (such as yeast infections or sexually transmitted infections), allergies or irritants, or poor hygiene.

2. Infection: Infections, particularly sexually transmitted infections (STIs) like herpes or chlamydia, can cause inflammation and redness of the foreskin.

3. Allergic reactions: Allergies to certain soaps, detergents, or other substances that come into contact with the foreskin can cause redness and irritation.

4. Trauma or injury: Physical trauma or injury to the foreskin, such as from rough handling during sexual activity, can cause redness, bruising, and pain.

5. Certain skin conditions: Some skin conditions, such as psoriasis or eczema, can affect the foreskin and cause redness, itching, and irritation.

6. Tight foreskin (phimosis): In cases where the foreskin is too tight and cannot be retracted easily, it can cause irritation, inflammation, and redness of the foreskin.

7. Poor hygiene: Inadequate hygiene, particularly in the genital area, can create a favorable environment for bacteria or yeast growth, leading to inflammation and redness of the foreskin.

8. Medication side effects: Some medications, such as certain antibiotics or chemotherapy drugs, can cause skin reactions, including redness of the foreskin.

9. Cancer: In rare cases, a red foreskin could be a sign of cancer of the penis. However, this is usually accompanied by other symptoms like persistent sores or changes in the appearance of the penis.

If you notice redness of your foreskin, it's important to consult a healthcare professional to determine the underlying cause and receive appropriate treatment. Self-diagnosis and treatment are not advisable as some conditions may require specific medications or interventions.
