*P-value of comparing androgen levels at three time points.

^aRegression estimate of T1 - T0 changes, values in bold have statistical significance.

^bRegression estimate of T2 - T0 changes, values in bold have statistical significance.

^cRegression estimate of comparing the refitting lines of G1 with G0 and G2 with G0, values in bold have statistical significance.

T, testosterone.

T0: T levels at baseline, T1: T levels on the trigger day, and T2: T levels on the day after the trigger day.
