Acquired cryptorchidism mainly refers to the fact that the testicles can be felt in the scrotum at birth, but they are not usually felt. This condition is mainly seen in many obese children, who are overly obese and have a large amount of fatty tissue accumulated in the groin area and perineum, and the development of the scrotum is small, so that the testicles are usually not felt when the scrotum is in a taut state. Ultrasound can confirm that the testes are below the groin and not in the inguinal canal, they are in the scrotum. It is suggested that the obese child must pay attention to weight loss and should exercise more in general, the scrotum should be effectively stretched more to promote the development of the scrotum, so that the testicles will automatically descend into the scrotum.
