What causes men’s testicles to be cold?

Cold testicles may be caused by abnormal scrotal temperature regulation, blood circulation disorders, chronic prostatitis, varicocele, hypothyroidism, etc. As an important male reproductive organ, the testicles are relatively sensitive to temperature changes, and potential causes need to be investigated in a timely manner.

1. Abnormal scrotal temperature regulation

The skin of the scrotum has a special thermal regulation function. When the ambient temperature is too low or the clothes are too tight, excessive local heat dissipation may occur. Behaviors such as sitting for long periods of time and taking cold baths will interfere with the voluntary contraction function of the scrotum, causing continued coldness of the testicles. It is recommended to wear breathable cotton underwear to avoid long-term exposure to low temperature environments. If necessary, you can use a warm water sitz bath to improve it.

2. Blood circulation disorder

Arteriosclerosis, diabetic vasculopathy, etc. may affect the perineal blood supply, resulting in insufficient perfusion of testicular tissue. Such patients are often accompanied by symptoms such as numbness of the lower limbs and intermittent claudication. Improvement requires controlling underlying diseases, moderate levator ani exercises to promote pelvic blood circulation, and severe cases require vascular surgical evaluation.

3. Chronic prostatitis

There is a nerve reflex connection between the prostate and testicles, and chronic inflammation may cause abnormal testicular temperature perception through nerve reflex arcs. Patients are often accompanied by frequent urination and perineal swelling and pain. They can use Qianlieshutong Capsules and Tamsulosin Hydrochloride Sustained-release Capsules combined with warm water sitz baths to relieve symptoms as directed by the doctor.

4. Varicocele

Obstruction of spermatic vein return will lead to the accumulation of local metabolic waste in the testicles and affect the temperature regulation function. The incidence rate is higher on the left side, and in severe cases, earthworm-like protrusions on the surface of the scrotum can be seen. Mild cases can be improved by scrotal support, while severe cases require surgical treatment such as high spermatic vein ligation.

5. Hypothyroidism

Thyroid hormone deficiency will lead to a decrease in the basal metabolic rate of the whole body, manifested by cold limbs and low testicular temperature. Patients are often accompanied by fatigue and weight gain, and require oral levothyroxine sodium tablets for replacement therapy after diagnosis by the endocrinology department, and regular monitoring of thyroid function.

In daily life, you should avoid sitting and cycling for long periods of time, reduce the intake of tobacco and alcohol, and maintain moderate aerobic exercise to promote blood circulation throughout the body. If it is accompanied by pain, induration or decreased fertility, you need to see a urology department promptly for scrotal color ultrasound, hormone level testing and other examinations. Breathable thermal protective gear can be used in winter, but care must be taken to avoid excessive local heat.
