What is the reason for cold balls?

Coldness in the scrotum may be caused by low ambient temperature, poor blood circulation, varicocele, chronic prostatitis, hypothyroidism, etc.

1. Low ambient temperature:

The skin of the scrotum is thin and rich in temperature receptors. When the ambient temperature drops sharply or when you wear too little, local blood vessels constrict and reduce heat dissipation, causing the scrotal temperature to be significantly lower than the body temperature. Being in a low temperature environment for a long time may affect the spermatogenic function of the testicles. It is recommended to keep warm in winter and avoid sitting on cold objects for long periods of time.

2. Poor blood circulation:

Sitting for long periods of time, compression from tight pants, or vascular disease can cause blood flow to the scrotal area to slow down. When accompanied by symptoms such as lower limb edema and varicose veins, circulation can be improved through levator exercises and warm water sitz baths. Diabetic patients who experience persistent chills should be investigated for vascular neuropathy.

3. Varicocele:

When the left spermatic vein backflow is blocked, congestion causes abnormal scrotal temperature regulation, which manifests as swollen, swollen and cold scrotum on the affected side, which is aggravated by standing and relieved by lying down. Severe varicose veins may be accompanied by testicular atrophy, which can be diagnosed by ultrasound, while mild cases can be alleviated by scrotal tape.

4. Chronic prostatitis:

When pelvic congestion and inflammation spread to the scrotum, it may cause symptoms such as coolness in the perineum, frequent urination and urgency. Such patients are often accompanied by anxiety and need to cooperate with psychological counseling to avoid excessive attention to local temperature changes.

5. Hypothyroidism:

Patients with hypothyroidism have a decreased basal metabolic rate, obvious symptoms of cold sensitivity throughout the body, and the scrotal temperature is often lower than 35°C. When symptoms such as fatigue, hair loss, and constipation are present at the same time, thyroid hormone levels need to be tested, and hormone replacement therapy can improve them.

Daily recommendations include wearing breathable cotton underwear to avoid local moisture, brisk walking or swimming three times a week to promote pelvic blood circulation, and adding an appropriate amount of zinc-containing foods such as walnuts and oysters to the diet. If the scrotum remains cold and accompanied by pain, induration, or fertility problems, it is necessary to promptly check for testicular torsion, hydrocele and other diseases. In winter, you can use warm baby clothes to keep warm, but you need to prevent low-temperature burns. The temperature is suitable for applying on the back of the hand without burning.
