Why is the male scrotum moist?

Moisture in the male scrotum may be caused by environmental factors, strong secretion of local sweat glands, fungal infection, scrotal eczema, varicocele, etc. It can be improved by keeping the area dry, drug treatment, surgery, etc.

1. Environmental factors

Being in a hot and humid environment for a long time or wearing underwear with poor breathability may cause local sweat evaporation in the scrotum to decrease. It is recommended to choose pure cotton loose underwear to avoid sitting for a long time. When the working environment is stuffy and hot, you can ventilate regularly to dissipate heat. It can be washed with warm water and dried daily. No special medication is required.

2. Strong sweat gland secretion

In some men, apocrine sweat glands are densely distributed in the scrotum, and excessive sweating may occur during exercise or stress. This condition is a physiological change and can be alleviated by wearing breathable clothing and using sweat-absorbent powder. If combined with odor or itching, it is necessary to check for secondary infection.

3. Fungal infection

Invasion by fungi such as Trichophyton rubrum may cause tinea cruris to spread to the scrotum, manifesting as erythema, scaling and moisture. The diagnosis requires a scurf microscopic examination, and antifungal drugs such as bifonazole cream, miconazole nitrate powder, or terbinafine spray can be used as directed by the doctor. The course of treatment usually lasts 2-4 weeks.

4. Scrotal eczema

Allergic dermatoses may cause damage to the scrotal skin barrier and the appearance of exudative papules with maceration. The onset is related to factors such as exposure to chemical detergents and mental stress. Boric acid solution can be used as a cold compress in the acute stage, and hydrocortisone butyrate cream combined with tacrolimus ointment is recommended in the chronic stage.

5. Varicocele

Venous return disorder will cause abnormal scrotal temperature regulation, manifested as swollen and moist scrotum on the affected side. Mild cases can be improved by scrotal support, while moderate to severe cases require laparoscopic high ligation of the spermatic vein. This disease may affect sperm quality, and men of childbearing age should seek medical attention as soon as possible for evaluation.

In daily life, you should avoid spicy food and reduce your intake of tobacco and alcohol. The water temperature should not be too high when taking a bath, and dry the wrinkled area thoroughly after cleaning. If the symptoms of dampness last for more than two weeks or are accompanied by redness, swelling, and ulceration, you need to see a dermatologist or urologist in time. You can sleep naked or wear mesh underwear at night to maintain ventilation, and change clothes in time after exercise. It is not recommended to use antiperspirant or alcohol-based talcum powder on your own to avoid irritating sensitive skin.
