What’s going on with the testicles squirming back and forth?

Testicular creeping back and forth may be caused by physiological factors and cryptorchidism.
1. Physiological factors: when men engage in some strenuous exercise, such as running or playing ball games, the testicles may move back and forth without other clinical symptoms, and may return to normal when resting, and no other treatment is needed.
2. Cryptorchidism: it may be related to genetic factors, anatomical disorders, endocrine disorders and other factors, which can lead to testicular back and forth creeping, and may be accompanied by scrotal flattening, asymmetric scrotum, abdominal mass and other symptoms, which can lead to testicular injury, cryptorchidism torsion, male infertility and other complications in serious cases.
If the testicle moves back and forth and is accompanied by other clinical symptoms, it is recommended to consult a doctor in time.
