FIG. 3. (A) Average circulating T in calling (n ¼ 20) and non-calling males (n ¼ 16). The numbers on the bars indicate sample size. T was significantly higher in callers (t34 ¼ 2.987; P, 0.01). (B) Average circulating CORT in calling (n ¼ 19) and non-calling (n ¼ 17) males, where CORT was elevated in non-callers (t ¼ 2.153; P ¼ 0.0381). Box size is based on the range of data points falling between the 2nd and 3rd quartiles. Mean is represented by 36 the filled circle and median by the bold line.
