Testicular retraction is mostly normal, and in rare cases surgery is required. Surgery is usually required for sliding testicles. Testicular retraction is a normal physiological phenomenon that can occur under the influence of external temperatures. In rare cases, testicular retraction may also be due to a sliding testicle, cryptorchidism, etc., which may require aggressive surgical treatment. While the testicles remain in the scrotum under normal physiological conditions, a sliding testicle is a testicle that retracts into the inguinal region, which needs to be differentiated from testicular retraction. It may lead to atrophy or hypoplasia of the testicle, which can be treated surgically with testicular immobilization. If testicular retraction or sliding testicle is found, it should seek medical treatment in time and under doctor’s guidance, and should not be treated without authorization, so as to avoid delaying the condition. Pay attention to rest on weekdays and avoid overwork.
