If the testicles are one in front of the other, it is recommended to go to the hospital for relevant examinations to clarify the possible causes: 1. When suffering from testicular sphingomyelia, there can be asymmetric testicular position on both sides. The testicles on the diseased side increase in size and are positioned slightly backward, while the testicles on the normal side are positioned more forward, which is usually not accompanied by pain when touched, and can be accompanied by an enlarged scrotal volume with elevated surface tension. The testicular position on the side with syringomyelia is not clear on palpation and requires ultrasound examination of the scrotum to confirm the diagnosis. 2. With severe varicocele, many spermatic veins accumulate in the scrotum, which can cause the scrotum to be positioned slightly forward, while The normal position of the scrotum is slightly backward, and when touched by hand, the testicle is slightly swollen or atrophied, and is accompanied by varicose vascular tissue in the scrotum, with a certain degree of swelling and pain, which is aggravated after activity and can be reduced after rest. It can be accompanied by an increase in the volume of the epididymis and local pain in the acute stage, which needs to be further identified by scrotal ultrasound and tuberculin examination.
