Data are presented on Testosterone Production Rate TPR in eight normal men acutely exposed to high altitude. The mean control value at sea level was 6.693 mg24 hr. similar to that obtained after 60 hr. in Cerro de Pasco altitude 14.200 ft 5.648 mg24 hs. p0.5. However, there was a considerable individual variation and no correlation between the TPR and the urinary excretion of testosterone. It is concluded that the determination of the TPR by urinary methods is not adequate in circumstances of adrenal stimulation by ACTH. The excretion of radioactivity in the urine was similar at sea level and high altitude 79.4 and 78.2 respectively the same occurred with the 17-Ketosteroids for which mean values were 19.77 and 22.09 mg48 hr. p0.5.
