Testosterone-cortisol ratio

In human biology, the testosterone-cortisol ratio describes the ratio between testosterone, the primary male sex hormone and an anabolic steroid, and cortisol, another steroid hormone, in the human body.[1]

The ratio is often used as a biomarker of physiological stress in athletes during training, during athletic performance, and during recovery, and has been explored as a predictor of performance.[1][2][3] At least among weight-lifters, the ratio tracks linearly with increases in training volume over the first year of training but the relationship breaks down after that.[1] A lower ratio in weight-lifters just prior to performance appears to predict better performance.[1]

The ratio has been studied as a possible biomarker for criminal aggression, but as of 2009 its usefulness was uncertain.[4]
