abstract：:Rats were made unilaterally cryptorchid by cutting the gubernaculum testis at birth. At 100 days age, the rats were injected with 600 IU/kg hCG. A biphasic testosterone response was seen in the scrotal (Scr) testis in response to hCG, with maxima at 1 h and 3 days after injection. The acute peak of testosterone was of...
