Is it normal for my testicles to feel cool to the touch?

It is generally normal for the testicles to feel cool to the touch, and may be related to the temperature regulation function of the scrotum. The testicles need to maintain an environment below body temperature to ensure normal sperm production, and the scrotal skin contracts or relaxes to regulate local temperature.

The skin of the scrotum is distributed with a large number of sweat glands and blood vessel networks. When the ambient temperature is low or you sit for a long time, the scrotum will shrink to reduce heat dissipation. At this time, the scrotum may feel cool to the touch. This physiological temperature change is usually accompanied by an increase in scrotal skin folds without pain, swelling or other abnormal symptoms. In daily life, you should avoid prolonged exposure to low temperatures and wear breathable underwear to help maintain a suitable temperature.

If the testicles continue to be cold accompanied by a purple color, dull pain or hardening of the scrotum, it may be related to pathological factors such as varicocele and insufficient blood supply to the testicles. Abnormal contraction of blood vessels in a low temperature environment may lead to local blood circulation disorders. This may be accompanied by a feeling of scrotal swelling or the palpation of vermiform masses when standing. This type of situation needs to be diagnosed clearly through scrotal ultrasonography, and if necessary, drugs to improve circulation or surgical treatment may be required.

It is recommended to avoid wearing tight pants or sitting for long periods of time to compress the perineum. When bathing, you can gently clean the scrotal skin with warm water. If persistent abnormalities in testicular temperature are found accompanied by volume changes, pain and other symptoms, you should promptly seek medical attention from a urology department to investigate vascular or neuromodulatory abnormalities. When doing outdoor activities in winter, keep your perineum warm and avoid direct contact with cold objects.
