What causes dampness in the scrotum?

Moisture in the scrotum may be caused by environmental irritation, inadequate hygiene, eczema, varicocele, prostatitis, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Environmental Irritation

The scrotum is part of the male reproductive system and plays a role in regulating local temperature. Exposure to high temperatures or prolonged wearing of tight, non-breathable underwear can easily elevate the temperature in the scrotal area. In response, the scrotum may sweat to cool down—this is a normal physiological phenomenon. It is advisable to wear loose, breathable underwear and avoid tight pants or synthetic materials. Maintaining proper local hygiene and keeping the area dry is beneficial for health.

2. Inadequate Hygiene

Incomplete daily cleaning can lead to accumulation of sweat and dirt on the scrotum, resulting in local moisture. It is recommended to maintain good personal hygiene practices, including washing the scrotum and genital area daily, which helps keep the area clean and dry.

3. Eczema

Eczema is primarily caused by factors such as allergies or local irritation, which can trigger inflammation of the scrotal skin, leading to symptoms like redness, swelling, dampness, flaking, and even erosion. Patients are advised to use medications such as hydrocortisone cream, compound dexamethasone cream, or triamcinolone acetonide-chloramphenicol solution as directed by a physician.

4. Varicocele

This condition may be related to venous valve insufficiency or weak venous walls. When affected, blood flow in the internal spermatic veins may become obstructed, causing blood to pool in the scrotum, which may result in the aforementioned symptoms and possibly a dull ache in the scrotum. Patients should follow medical advice and take medications such as ibuprofen sustained-release capsules, flavoxate hydrochloride tablets, or tamoxifen citrate tablets as prescribed.

5. Prostatitis

This may be associated with bacterial infection or unhealthy lifestyle habits. Inflammation caused by the condition can increase prostatic secretions, potentially leading to scrotal moisture, along with symptoms such as frequent urination and urgency. Patients are advised to take medications such as ciprofloxacin hydrochloride tablets, amoxicillin tablets, or minocycline hydrochloride capsules under a doctor’s supervision to improve symptoms.

In daily life, patients are encouraged to eat a light diet, change underwear regularly, avoid strenuous exercise, drink plenty of warm water, and refrain from staying up late—all of which are beneficial for overall health.
