I. Can cryptorchidism be touched? Cryptorchidism can generally be touched if it is in the groin, but not if it is in the abdominal cavity or other locations. The cryptorchidism that cannot be touched may also be congenital testicular agenesis or testicular atrophy, which must be clarified through surgical exploration. 2.Does cryptorchidism have to be operated? If the testicle does not descend or is in an abnormal position, without the temperature regulation of the scrotum, the texture of the testicle will change. As time lengthens, the hidden testicle will shrink and the tissue that produces sperm will be underdeveloped. The chance of cancer in a cryptorchid is about 30-50 times higher than in a normally positioned testicle. Early descent of the testicle into the scrotum can significantly reduce the possibility of malignant transformation. When is the best time to have surgery for cryptorchidism? To minimize the impact of cryptorchidism on the reproductive function of children, testicular descent surgery must be performed before the age of 2. IV. Is cryptorchidism surgery big? What are the complications? Cryptorchidism surgery is done delicately, mainly by loosening some unnecessary tissues, making the spermatic cord long enough and then fixing the testicle in the scrotum. The development of the testicle after cryptorchidism surgery is determined by its own nature. It may develop well in the future, or there may be complications such as atrophy (becoming smaller or absent) or retraction (due to the short spermatic cord and the high tension of the pulling, the testicle goes back up and is not in the scrotum). A retracted testicle needs to be operated on again.
