Generally speaking, the “balls” – the testicles – are characterized by a large degree of mobility and protected by a tough white membrane, and are not easily damaged. Most injuries are caused by closed injuries, such as those caused by bruises, kicks, ball strikes, riding injuries and traffic accidents. In general, if there is no obvious hematoma and sphingomyelia, most of the testicular contusions can heal on their own with bed rest, cold compresses and anti-inflammatory symptomatic treatment. For open testicular injuries and closed testicular injuries with severe bleeding, you should go to the hospital for early examination and active surgical investigation to remove the hematoma and repair the white membrane of the testicle to preserve the function and tissue of the testicle as much as possible. And the best way to diagnose testicular injury at present is also the examination – ultrasound. It is worth noting here that in case of a particularly unfortunate accident of severe bilateral testicular injury, there will still be some residual sperm in the testicular tissue for a few weeks at this time, and we should freeze the residual sperm in time to meet the patient’s future fertility requirements.
