[Evaluation of the testicular function using the HCG test in normal and cryptorchid children]

The testicular function has been evaluated by a single dose hCG-test in normal and cryptorchid prepubertal boys using three different protocols. No remarkable difference has been observed using different posologic protocols. Testicular function in boys affected by cryptorchidism was similar to the testicular function in normal controls. However cryptorchid boys older than 6 years of age showed a significant reduction in testicular response to hCG-test in comparison to cryptorchid boys younger than 6 years of age
