The initial manifestation of an impact on the testicle is pain. Because there is an envelope on the outside of the testicle, the testicle is a substantial organ and when it is impacted, there is a sudden increase in tension on the inside. If the impact is weak, the pain will be more obvious. If the impact force is too strong, it may cause the parenchyma of the testicle to rupture and bleed, or even the peritoneum of the testicle to rupture and bleed. It is recommended that if the pain persists more obviously after the testicle is impacted, you must go to the hospital for an ultrasound examination of the scrotum to observe whether there is a hematoma in the testicle and whether the testicle has ruptured. If there is no rupture and no hematoma, rest in bed and observe closely. If there is a rupture, it is recommended that an emergency surgical exploration should be performed to remove the hematoma and repair the testicle.
